Examples of how we stimulate innovation across the highways sector

We align our projects with our five innovation themes:

• design, construction and maintenance​
• connected and autonomous vehicles​
• customer mobility​
• energy and environment ​

Our projects are generally cross-cutting, applying to more than one theme.

Design construction and maintenance

Trimble sitevision– augmenting reality, the challenge.

We have been using drawings to explain where services and structures are located for many years. This requires both excellent drawing skills, and the ability to visualise the drawn data in the real-world environment, which can be a complex task.

The project

As part of the A14 Cambridge to Huntingdon project, we trialled the mixed-reality application Trimble SiteVision.

SiteVision uses cloud stored geospatial data, allowing on-site users to:

• visualise buried assets and building information models (BIM) live in the field.
• easily note and report back issues and observations

In the recent pandemic, we successfully trialled Trimble SiteVision together with Microsoft Teams. This helped the offsite engineering team to understand construction issues that site based workforce were experiencing.

Although it needs good data and good internet connection, the SiteVision device brought benefits from day one. It reduced the number of engineering visits needed for site clearance and boundary works as well as flagging potential issues earlier than normal.

Automated cone laying vehicles

We need cones to protect road users and road workers while essential work is carried out on our roads.

At the moment, putting out cones is still a manual task, involving two people on the rear of a vehicle working in tandem.

We do most of this work at night, in all weather. Workers can lift up to 10 tonnes of equipment per shift. With motorway traffic thundering past, it can be a dangerous and frightening task.

Working with a group of industry experts, we have developed two automated vehicles which will take the human element out of cone laying.

Our aim is for both vehicles to be the routine go-to options for cone laying on our network. This will eliminate one of the biggest risks facing roadworkers.

Highways Care

The Highways Care vehicle has completed its on-road trials and can now be taken out to the marketplace for use on the strategic road network.

King Highway Products

The second vehicle, developed by King Highway Products, is quite different. It uses a ‘revolver’ style rotating drum to lay and collect cones.

The King vehicle has recently completed extensive off-road testing at Manston Airport, Kent.

If successful, it will also be taken out to the marketplace along with the Highways Care version, for use on the strategic road network.

Design, construction and maintenance

Transforming road markings

We’re always looking to improve how we operate and maintain our roads.

When road markings need to be altered or removed, for example when lane layouts change, faint traces of the original markings can remain.

These 'ghost lines' can confuse motorists, particularly in very bright or wet conditions.

The competition

In partnership with Roadcare and Kier, We launched a global search for effective roadmarkings that:

• can be completely removed without damaging the road surface
• don’t leave ‘ghost lines’.

We used our Innovation Designated Fund to help finance the competition.

We received thirty-six entries from around the world. We chose seven winners and tested their materials including:

• lab trials in Madrid, where products were subjected to two million 'wheel overs'
• real-world all-weather testing on the M5 motorway in South West England.

The results

After laboratory testing, we installed the winning solutions on the M5 in April 2019. We tested their performance periodically and assessed the results against data from the laboratory turntable testing. We also tested five removal systems on each of the markings.

After two years of testing in all weathers on a stretch of road that saw 31 million vehicles pass through in that time, we have produced a full report of our findings.

The findings are to be considered as part of a road markings action plan within National Highways.

Connected and autonomous vehicles

Connected and autonomous plant (cap), the opportunity.

The introduction of Connected and Autonomous Plant (CAP) will positively change all aspects of the construction industry. The possible benefits of this new technology are vast.

We should explore, develop and adopt CAP across the highway sector.

As part of our digital roads vision, together with i3P, we led the development of a roadmap to 2035, for the introduction and implementation of CAP.

This was a collaborative project which drew together over 70 representatives from clients, academia, industry, and government.

Stakeholders shared the development of the vision and explored how to overcome challenges in technology, standards, legal and commercial constraints.

The uptake of CAP into the construction industry could deliver a 20-25% improvement to construction productivity and transform safety.

The roadmap challenges industry to work together to embed digital and automated techniques to revolutionise construction.

Design, construction and maintenance Connected and autonomous Vehicles

We're always looking for ways to use our existing infrastructure to push out information about traffic updates, speed limits and diversions – helping vehicles to plan journeys more effectively. This is a key part of our Digital Strategy .

Technology has emerged in recent years that allows us to make wider use of our lighting infrastructure. The roll-out of 5G and the IoT (Internet of Things) makes it practical to equip lights with devices such as wireless access points and cameras.

​The project​

Together with Kier Highways, we carried out a proof-of-concept trial on the Illuminate intelligent street lighting system at M40 junction 15 Longbridge roundabout near Birmingham. ​

We installed CCTV and communications technology in street lamps at the same time as we upgraded them to greener, more energy efficient LED lighting.

The Illuminate trial took place over five months in 2021 and successfully proved the concept. The technology was able to communicate data to office equipment and tablet computers.

Installing communication technology when we replace street lighting is efficient and safe. It's also less disruptive to the public, as it reduces the number of road closures we need.​

​The knowledge gained from the trial will help to shape our strategy for managing the Connected and Autonomous (CAV) infrastructure.

Customer mobility

Mobile barrier

Working in live lanes is a real risk to our workforce.

To work safely, we often need full carriageway closures which inconveniences road users. With increased traffic volumes this also puts more pressure on the network.​

​The mobile barrier provides exceptional protection for both road workers and motorists and reduces the severity of incidents in and around work zones.​

​It provides physical protection, absorbing the impact of vehicles strikes from the side. A lorry mounted crash cushion gives protection from the rear, with approved lighting and signage providing ample visibility for all.​​

The barrier offers a number of benefits to road workers, including:​

• ​all round impact protection
• available for use 24/7 with correct maintenance
• versatile and adaptable to near-end far side works
• less resources, exposure time and costs with the ability to mirror off-side lane closure
• reduced overall night shifts on schemes​

​We are working with Kier we're exploring how the US made barrier can enhance safety measures and reduce road worker exposure. ​

​Mobile barriers are an innovative way of to increase protection for road workers. ​They’re helping customers too, because the faster we can get the work done safely, the better people’s journeys will be.

iDrain – intelligent flood alert system

Flooding is one of the greatest persistent problems faced by the national strategic road infrastructure. It is becoming an increasing risk due to more severe weather events and ageing underground pipe networks that are difficult to monitor.

The risk of road traffic accidents and closures increases significantly during periods of heavy rain. Excessive carriageway surface water significantly reduces skid resistance. In extreme cases, it can cause aquaplaning and total loss of control.

Together with Carnell, we developed a low-cost sensor connected solution that is triggered when water in drainage systems reaches criterial levels.

Designed to prevent flooding events on the strategic road network, iDrain allows us to monitor drainage chamber water levels remotely. It provides accurate live data on high risk flooding areas so we can target proactive maintenance.

If widely adopted, the solution will help reduce accidents and road closures, improve reliability on the network and ultimately boost the economy.

Design, construction and maintenance Customer mobility Operations

Progress-O-Meter

The Progress-O-Meter is a customer information board which displays a monthly countdown and progress bar to scheme completion. We designed this initiative to help improve customer confidence that we will meet advertised roadwork completion dates.

During a trial on the M6 between junctions 13 and 15, we conducted customer insight surveys to gauge reactions to the Progress-O-Meter boards. We also sought trial scheme feedback and monitored social media activity. We assessed the safety impact of the Progress-O-Meter billboards using closed-circuit television (CCTV) monitoring and M6 J13-15 incident logs.

The trial findings indicate that the board was considered safe and that customers liked the information we were giving. Almost all customers who saw the Progress-O-Meter said they gained some new information about the progress of the roadworks. All of these customers found the new information very or fairly useful.

We’re hoping that after some additional trialling on other schemes, we can roll this initiative out on all Major Projects roadwork. We hope customers will feel more satisfied when driving through roadworks with the awareness that work is progressing.

Energy and environment

Warm mix asphalts.

One of many steps we’re taking to reduce our carbon emissions is encouraging the use of warm mix asphalts (WMAs) as standard across our supply chain.

Typical asphalts are produced at up to 190°C.

The simple principle behind WMA technologies is manufacturing asphalt at reduced temperatures but with additional additives

This uses less energy and delivers meaningful carbon savings without compromising performance.

WMA is produced at temperatures up to 40°C lower than traditional asphalt.

If all production in the UK switched to WMA, it would save around 61,000 tonnes of CO2e a year. This is equivalent to cutting around 300 million miles of car journeys.

With a shorter cooling time and reduced risk of early life deformation, WMA allows longer working windows and increased shift outputs. It can also be recycled back into new asphalts, preventing waste.

In addition to carbon reduction and increased productivity, some of the other key benefits of switching to warm mix asphalts include:

Improved health and safety

Reduced temperatures help reduce risks associated with producing and laying asphalt at high temperatures such as

• exposure to fumes
• steam causing reduced visibility, particularly when wearing safety eyewear

WMA reduces fume generation by around 50% for each 10°C reduction in temperature.

Improved durability

As WMA is laid at lower temperatures and an increased amount can be laid in a single shift. It needs fewer construction joints in the road and less maintenance in the future.

Our next step is encouraging everybody involved in building and maintaining the strategic road network, particularly designers and main contractors, to use WMAs.

More widespread use of WMA will help us achieve our aim of net zero carbon maintenance and construction activities by 2040. Best of all, WMAs can be laid using conventional paving equipment.

Design, construction and maintenance​ Energy and environment ​ Operations

Hyperspectral remote sensing

The oportunity.

In a ground-breaking project with Network Rail, we trialled new technology on helicopters to monitor the country’s rail and road networks.

With ‘eyes in the sky’, our teams explored how we could:

• improve road and rail network management and maintenance
• protect our workforce by reducing the amount of time spent on physical inspections.

Using a helicopter equipped with the latest aerial remote sensing technology, we assessed the UK’s road and rail networks, which are often close to each other.

We trialled various technologies - hyperspectral remote sensor imaging, LiDAR and aerial photography - to assess their potential for monitoring the condition of assets such as manholes, pipes and drainage systems. These technologies could also be used to identify faults in our network so we can perform vital maintenance and renewal work more effectively.

The information gathered in this trial has helped us and Network Rail:

• explore new ways to monitor and maintain our networks
• understand potential infrastructure risks
• improve road safety and plan maintenance.

Due to the successful joint working through this project, our organisations are now working on plans for further trials and collaborations.

Design, construction and maintenance Energy and environment

Green light optimal speed advisory (GLOSA)

In 2019, we ran a competition seeking innovative ideas for developing digital roads and improving air quality.

One winning entry explored technology known as Green Light Optimised Speed Advisory (GLOSA). ​

GLOSA gives drivers speed information that helps them to pass through green traffic lights. This reduces the number of vehicle stop-starts at signalised motorway junctions and can, in turn, improve air quality.​

​The project

We worked with Amey to develop and trial the in-vehicle technology. Other partners involved included:​

• Transport for Greater Manchester (TfGM) – for traffic control systems access​
• Eastpoint – to develop the GLOSA app​
• Ricardo – for emissions testing​

​We ran the trial using traffic lights on three slip roads in the north west.

• the A627(M) Broadway junction
• the north and southbound roundabout approaches at junction 2 of the M66

We used a portable emission measurement system to capture real driving emissions data on these short routes.

We used two vehicles, a light commercial vehicle and a heavy goods vehicle (HGV), completing around 400 trips for the trial. We generated comparable data by doing a number of runs on the same slip road.

Initial analysis of results suggests that vehicle CO2 emissions were reduced by as much as 27% by minimising unnecessary speed changes.

This also led to a 17% reduction in the level of nitrogen oxide (NOx). The most promising results were from HGV testing.​

​We are now testing the technology with a different type of traffic signal control system. If testing is successful, we will start working on a GLOSA Strategy for potential roll-out in our third road period (RIS3 2025-2030).

Wiping out graffiti

We are on a mission to tackle the blight of graffiti by finding new products to remove graffiti but also potential solutions that will prevent the vandalism appearing in the first place.

Graffiti on bridges and next to roads can be distracting for drivers and the clean-up often requires lane or road closures, disrupting traffic. And it is costly – up to £10,000 to remove one instance of graffiti.

We launched a competition with partners Kier and Connected Places Catapult to identify new solutions for dealing with graffiti. The programme sought to award up to six organisations with £30,000 to design a trial of their technology on a road network testbed.

The technology could include:

• Behaviour detection and analysis
• Solutions to reduce disruption to the road network while maintenance work is being carried out
• Visual deterrents
• Surveillance and CCTV
• Removable green walls
• Anti-graffiti coatings and paint
• Asset management solutions

More than a dozen companies submitted their concepts and products. The five most promising are now developing their ideas. They will produce a feasibility study for National Highways to decide on the most promising products to take forward for use on the road network.

The five winning ideas are:

• Audio sensors that will detect the application of graffiti to alert authorities and trigger audio and visual deterrents.
• Artificial Intelligence software that will analyse behaviour to detect vandals at graffiti hotspots and then deterrents such as alarms and lights can be activated.
• Wall-climbing robotics that apply graffiti preventative paints, reducing the risk of such hazards as working at heights for the workforce.
• Using lasers to remove graffiti from surfaces whilst preventing additional damage to the finish of surface coatings and films.
• A 3D chemical coating to prevent the adhesion of graffiti to a variety of surfaces and films.

Maintenance Operations

Road workers are continually exposed to hazards associated with traffic and movement of vehicles on site.

Developed by Carnell, SAFETYcam vans are an intelligent site safety innovation that protects road workers by using two complimentary vehicle detection systems. They record instances of dangerous driving and provide a conspicuous visual deterrent to poor driver behaviour.

When deployed, SAFETYcam virtually eliminates deliberate vehicle incursions and dramatically reduces the number of site vehicles exceeding site speed restrictions.

Features include:

• front and rear high definition video cameras
• speed camera (rear)
• Automatic Number Plate Recognition (ANPR) system
• cloud-based data capture
• on-board wi-fi
• watermarked hard drive
• operator workspace
• welfare facilities

We funded trials using four SAFETYcam vans over a 12-month period. They proved successful in reducing site speeds, clearly demonstrating a positive change in site driver behaviour. We are now implementing the initiative on a wider scale.

During recent works, we used data collected from the onboard ANPR technology to develop a road safety campaign with the Central Motorway Police Group. This included 'education letters' to the registered keepers of 450 vehicles found exceeding the speed restrictions.

Design, construction and maintenance​ Operations

Enhanced customer response unit

Traditionally, we need up to three separate vehicles to deal with incidents on our network:

• Traffic Officer vehicle
• Asset Incident Watchman
• traffic management vehicle.

Our challenge was to develop more efficient approach to incident management, asset inspection and defect repair. Our focus was to improve journey times.

Working with Kier, we've trialled a new Enhanced customer response unit (ECRU).

The ECRU can transport both our Traffic Officers and Asset Incident Watchmen. It carries a greater variety of tools and equipment, so watchmen can carry out repairs and clean and sweep the road in a safer, faster and more efficient manner. This removes the need for other vehicles to attend the incident.

ECRU features include:

• jetting equipment for oil spillages
• on-board welfare facilities, including kitchen and toilet
• Variable Message Signs (VMS) and crash cushions
• a mechanical sweeper to quickly clear up of debris

As a front line response unit, the ECRU will significantly improve incident clear-up times.

The quicker we can return roads to normal service, the more we can ease congestion. Our roadworkers will be safer if they can spend less time exposed to risk on our network.

The recent introduction of Hybrid Annuity Model (HAM) for highway up gradation projects in India marks a significant policy departure. This is aimed at revitalizing private sector led infrastructure development. The model has been pitched as a panacea to the numerous ills plaguing the highway sector, which had led to a record fall in the award of new projects, both in numbers and in value. Taking a dispassionate look, this paper critically examines the extent to which HAM has fulfilled its stated objectives during its introductory stage. The analysis of project award data provides mixed empirical evidence of HAM's initial success. We find that as a development imperative, HAM does encourage private participation in highway infrastructure, and it is a step forward. However, HAM also suffers from extensive de-risking of the private sector, to the extent of making them unattractive for both debt and equity investment. By this, HAM takes the re-engagement of private sector two steps back. We concede that HAM is still in its infancy and a true performance would only be evident once enough number of projects have been delivered through this model. With this view, this paper adopts a more analytical stance, to identify possible pitfalls based upon the telltale signs. This is important as infrastructure projects have a long-life cycle, and an early stage dispassionate analysis and course correction is necessary, lest we move too far down the wrong path.

Uncontrolled population growth, fast urbanism, and industrialism have come from environmental challenges in recent decades. One of the most serious issues is waste as a result of poor management methods. This article provides an overview of current waste management strategies and how waste management techniques are being use by startups to generate cash. Resources are finite, so their use should be maximized, and good waste management is a critical component of achieving this aim. Local governments are being compelled to identify and implement innovative waste management strategies as public awareness of the environment grows. Separation at source, collection, sorting, recycling, composting, and sanitary landfilling are all part of the advised method for maximizing recycling and reducing landfilling of municipal solid waste. The practicality and economics of the recommended approach were also examined in this article.

The valuation of real estate is a central tenet for all businesses. Land and property are factors of production and, as with any other asset, the value of the land flows from the use to which it is put, and that in turn is dependent upon the demand (and supply) for the product that is produced. Valuation, in its simplest form, is the determination of the amount for which the property will transact on a particular date. However, there is a wide range of purposes for which valuations are required. These range from valuations for purchase and sale, transfer, tax assessment, expropriation, inheritance or estate settlement, investment and financing. The objective of the paper is to provide a brief overview of the methods used in real estate valuation. Valuation methods can be grouped as traditional and advanced. The traditional methods are regression models, etc. MRA has been implemented by many researchers to study valuation of real property cite that MRA is possible for coefficient estimates and factor weightings using a large number of actual sale cases.

In INDIA, BOT (Build Operate Transfer) approach has given an undeniably well known task financing to push toward framework improvement. There are numerous complexities in ventures on account of the assortment of elements in undertaking's pattern and furthermore the reliance of task. Because of the complexities and their drawn out working, the tasks meet with vulnerability and various dangers. This exploration study is to concentrate on the Indian foundation segment with an accentuation on various undertakings hazard factor. The advancement of the development area in india has been compratelly moderate. BOT(Build Operate Transfer) implies the administration move the admission to Private Company and the organization is liable for building, working the undertaking, and afterward move the task back to the legislature when the concession time frame terminates. The principle reason for this paper is to explore monetary hazard, specialized hazard, unique and support chance, remote trade risk and commercial chance in BOT projects. BOT venture is exposed to numerous dangers lastly it is changed over into money related risk.base on the audit the basic hazard are found :-change in law, cost overrun, delay in delay in endorsement , development plan budgetary shutting , traffic modification , natural hazard , and so forth The reason for this paper is to examine the hazard related with BOT plans in India

Contracts are highly crucial in any sector, and we all know that claims are quite easy to make in construction projects because there are so many parties involved and each project has its own set of characteristics. In India, the majority of construction contracts are based on the GCC developed by the CPWD, and it has been discovered that due to the rigorous nature of the GCC and differences in the nature, site, and kind of projects, construction industry conflicts are highly widespread. The report aims to demonstrate the efficiency of the CPWD's revised GCC and make recommendations for reducing public contract disputes. An attempt has been made by using real-life arbitration cases and anticipating many parameters. The amended clauses have been analyzed by comparing them to the old clauses, and an assessment has been performed to determine the root reasons of the claims. To make the clauses more understandable, they've been divided into different categories, and then claims have been linked to the relevant factors in various arbitration cases.

Health care is very important to start a good life. However, if you have a health problem, it is very difficult to talk to your doctor. Chatbots can be used to communicate with text or voice interfaces and receive responses via artificial intelligence. Chatbots are programs designed to automatically interact with incoming messages. Chatbots can be programmed to respond the same each time and respond differently to messages containing specific keywords. In addition, you can use machine learning to adapt your response to your situation. More and more hospitals, nursing homes, and even private centers are now using online human service chatbots on their websites. These bots connect with potential patients accessing the site, find specialists, make appointments, and ensure appropriate treatment. In any case, the use of artificial intelligence in industries where people's lives can be a problem still raises personal concerns. The question arises whether the above tasks should be left to human staff. This healthcare chatbot system helps hospitals provide 24/7 online healthcare support. It answers both deep and general questions. It also helps generate leads and automatically delivers lead information to sales. Asking in turn helps the patient by guiding them on exactly what they are looking for. I. ACKNOWLEDGEMENT Priyadarshini College of Engineering is a well established & renowned institute and follows a goal of creating technocrats and brings it into reality, which will perform challenging endeavor in technical field for welfare of human being.

The COVID-19 problem has hit the healthcare industry hard. On one hand, it was responsible for treating COVID-19 patients, but it also faced a number of obstacles, similar to those experienced by other industries. Throughout it all, the industry has had to constantly innovate and come up with new methods to care for people. There have been significant shifts in consumer tastes and behaviour when it comes to accessing healthcare services. Players in this industry would do well to comprehend these behavioural shifts and alter their methods of operation accordingly. In terms of revenue as well as manpower, healthcare has become one of the fastest growing sectors in India. Due to expanding coverage, efficiency, and increased spending by both public and private sectors, the sector is expanding at a lightning speed. In the future, increasing income levels, more health consciousness, and a shift in attitudes towards preventative healthcare are all predicted to increase demand for healthcare services. Healthcare tourism has grown as a result of reduced cost of medical treatments, drawing patients from all over the world.

The basic idea involved in the project is to identify the Constructional and Operational challenges faced in the execution of the highway project and to provide the feasible engineering and managerial solutions to the pertaining problems. Constructional challenges and Operational challenges go hand in hand for every construction project. Identification of the challenges before the initiation of the project is practically not possible. It may happen that the list of challenges before the starting of the project may be identified but there is a chance that a new challenge may be faced while execution and that is why most of the projects delay. When it comes to infrastructure projects like highways this problem is predominant. This is the major reason to categorize the challenges that were faced in highway project into challenges before construction, challenges during execution and challenges after construction. Hence this research project identifies some of the constructional and operational challenges in an infrastructure project with the help of a live case study on a highway project “Rehabilitation and Up-gradation of NH-67 from km 424/650 to km 487/693 (Gooty–Tadipatri section)” which is located in Anantapur district of Andhra Pradesh. Some of the constructional and operational challenges in the execution of the project were identified and proper solutions were specified for the successful completion of the project.

Case Study: National Highways

Appy days for National Highways

This case study highlights improved data management at the roadside and the impact that this has had on National Highways since adopting BORIS:

A new app is making road side data-gathering faster, smarter and easier.

As well as hazardous driving conditions, filling out paperwork at the roadside is an extra challenge for traffic officers.

But rain-soaked form-filling will soon be a thing of the past – thanks to BORIS.

BORIS is the name of an app on traffic officers’ handheld tablets. It has been customised to create paperless versions of incident report forms (IRFs), watchman reports, recovery satisfaction surveys and more.

Traffic Officer Neil York, based at the Sprotborough outstation on the A1/M in South Yorkshire, was among the colleagues who trialled the app ahead of its launch.

“It’s a huge improvement,” says Neil. “I used to carry a big pad of IRFs in the vehicle for example. When it was dark, cold and lashing down, these were a nightmare to complete in a live environment. Even when it was dry, there was a lot of admin work involved.”

“the app removes all these issues. the tablets are a splash-proof design and the app is extremely user friendly.”.

Of course, it’s about much more than avoiding soggy paperwork.

The app enables traffic officers to gather and send better quality information more quickly. Going paperless also means less admin for traffic officers at the end of a shift. With no data to be transcribed and entered manually, information that could previously take days to log centrally is now available within minutes. It means our teams can see, at-a-glance, all the activity in their region.

Better use of data and developing our IT to enable colleagues to work more effectively are key parts of our organisational plan. This sparked the rollout of tablet devices to traffic officers, of which the BORIS app is the second phase.

“Trials with traffic officers helped us to make the app as easy as possible to use,” says Project Manager Dan Healey, part of the team who developed BORIS.

“there are drop-down lists, pre-populated forms, gps location and time recording. photographs can also be taken and uploaded in seconds.”, “because the app stores the information even if there’s no signal, colleagues can start to complete the forms wherever it’s safe to do so and transmit them later. we’ve also built in flexibility for the app to be updated in the future.”.

Following the launch there was a marked increase in the quality and consistency of information in reports.

As well as helping us develop best practice by learning from incidents, BORIS is also helping us recover costs for damage to infrastructure. More timely and accurate information, especially combined with photographic evidence, means we can make stronger insurance claims.

For Neil, it’s a welcome step towards reducing paperwork and freeing up more time to spend helping customers.

“It really does take the leg work out of completing these forms,” he adds. “I’m quite switched on to technology but this app is so simple, even the least tech savvy people will be able to pick it up very easily.”

NIA seizes Rs 1.13 crore in Naxal Magadh zone revival case

In a major seizure linked with the naxal magadh zone attempted revival case, the national investigation agency (nia) on tuesday seized funds extorted from contractors and others in bihar and jharkhand which were used to finance the medical studies of a relative of some of the accused..

In a major seizure linked with the Naxal Magadh Zone attempted revival case, the National Investigation Agency (NIA) on Tuesday seized funds extorted from contractors and others in Bihar and Jharkhand which were used to finance the medical studies of a relative of some of the accused. The money, amounting to Rs 1,13,70,500, has been seized under the Unlawful Activities (Prevention) Act in the case RC-05/2021/NIA/RNC) registered suo moto by the NIA on December 30, 2021.

NIA investigations have revealed that the amount had been directly transferred to the bank account of a medical college in Chennai, Tamil Nadu for the medical education of a relative of a senior naxal leader. "The transfer was done through the bank accounts of close relatives of the accused persons, under the garb of a loan amount," said the NIA.

The NIA stated that the niece of the FIR-named chargesheeted accused and Special Area Committee naxal member Pradyuman Sharma is the beneficiary of the extorted funds. "She is also the sister of arrested chargesheeted accused Tarun Kumar and cousin of arrested chargesheeted accused Abhinav alias Gaurav alias Bittu," the NIA added.

On January 20, 2023, NIA filed a chargesheet before its Special Court in Jharkhand's Ranchi against two accused persons under various sections of Indian Penal Code and UA (P) Act. In June last year, it filed its first supplementary chargesheet in the case against one more accused, followed by a second supplementary chargesheet against two others in December 2023. (ANI)

Construction Manager-at-Risk Project Delivery for Highway Programs (2010)

Chapter: chapter two - literature, methodology, and case studies.

Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

11 INTRODUCTION This synthesis involves the investigation of the use of CMR by DOTs. This is accomplished through a review of literature to understand what CMR is and followed by a study method- ology that includes several different information collection approaches including CMR project case studies. LITERATURE SUMMARY The literature on CMR generally falls into one of two major categories. The first group encompasses journal papers and documents that report on a comparative analysis of two or more project delivery methods. The second category comprises information on the mechanics of implementing CMR as well as lessons learned from completed CMR projects. The first category is valuable in that it helps define the salient differ- ences between CMR and other project delivery methods at the operational level. Comparative Analysis of Project Delivery Method Performance The most often cited example from the first category is the paper by Konchar and Sanvido (1998) that compared dif- ferent project delivery methods (i.e., DB, DBB, and CMR) in 351 building projects with a standard set of performance criteria. The criteria were both objective and measurable. One of the results of the comparison is: “when all other variables were held constant, the effects of project delivery system indicated design/build projects to be at least 5.2% less than construction management at risk and 12.6% less than design/ bid/build projects on average in terms of cost growth” (Konchar and Sanvido 1998). The authors have divided the projects into six different groups (e.g., as light industrial, complex office, and heavy industrial) to get a more robust result about the trends in each group. The paper’s main conclusion is that CMR and DB projects tended to perform better in most mea- sured criteria than traditional DBB projects. Additionally, a recent NCHRP study of best value contracting (Scott et al. 2006) furnished direct comparison of transportation project performance between delivery methods. Although that study did not include CMR projects, it did include DBB projects awarded on a best value basis where the contractors’ qualifi- cations and past performance were factored into the selection process. This parallels the CMR delivery method. The study found that DB projects had 4.7% less cost growth and 9.3% less time growth. Best value projects had 2.0% less cost growth and 18.5% less time growth. One study in this category was specifically directed at owner perceptions of the various delivery methods (Doren et al. 2005). This was a joint effort between FMI Consulting and the Construction Management Association of America (CMAA). This study had a plethora of interesting findings that will be reported as appropriate throughout the synthesis. The one most directly related to the performance of CMR project delivery versus other delivery methods is summed up as follows: . . . when we asked which method was used most frequently, which is design-bid-build at 66% of all responses followed by CM-at-risk at only 19%. However, when asked which method delivers the best value, both CM-at-risk (35%) and design-build (29%) rated higher than design-bid-build (23%) (Doren et al. 2005; italics added). Thus, although DBB was used three times as often as CMR, CMR was perceived as the project delivery method that fur- nished the most value to the owner. The study went on to dis- cuss project delivery methods in the public sector. Changing the delivery methods used, in the case of these [public] organizations, will often require changing laws and politics, but that is happening, too, because the public is best served when it gets the best value for its tax dollars. . . . CM-at-risk will likely become the more dominant delivery method for this group (Doren et al. 2005; italics added). An article in the CMAA’s CM eJournal summarizes the issues discussed previously: The great advantage to CM-at-Risk for most public Owners is that their governing bodies accept it . . . Most Owners see having a GMP as equivalent to having a Stipulated Sum Cost, and on that basis are willing to enter the experiment . . . The choice then for most public Owners is between CM-at-Risk and the traditional [DBB] system. If they do not want to use the traditional method because of past poor results, and are not bold enough to try Design- Build, they are encouraged in this direction (Strang 2002). Construction Manager-at-Risk Implementation Experience The literature on implementing CMR contracting is reasonably rich and contains the lessons learned by public agencies in all transportation sectors. Rather than attempt to exhaustively relate all the successes and failures, the report will concentrate CHAPTER TWO LITERATURE, METHODOLOGY, AND CASE STUDIES

on those factors of CMR that were cited repetitively by a diverse group of authors and agencies. The ones that were found to be most important to understanding the aspects that impact successful CMR project delivery will be discussed in detail. Tables 1 and 2 summarize the advantages and dis- advantages found in the literature. If two or more authors specifically cited a specific factor as an advantage, it was recorded in Table 1. Then the disadvantages cited by the authors shown in Table 2 were tabulated to show their complete experience regardless of how many times an item was cited. The first thing that one can see in the tables is that the infor- mation is very current. Ten of the 15 citations were published between 2005 and 2009. This provides confirmation of the applicability of these experiences to transportation agencies that may be contemplating the use of CMR and are looking for information that will assist them in matching the project delivery method with their project requirements. The next general observation is that the authors appear to have more positive than negative information about CMR. Four of the 15 papers did not list any disadvantages, and there were 17 advantages cited that were offset by 13 disadvantages. Additionally, there are 4 advantages that were cited by at least 10 of the papers (two-thirds of the population), whereas all but one disadvantage was cited by one-third or less of the 12 sample. This appears to infer that the experience with CMR project delivery has generally been positive. It also provides confirmation to the results of the comparison of CMR with other delivery methods discussed in the previous section. From Table 1, the top five advantages based on frequency of citation in the literature are: 1. The ability of the constructor to make substantive/ beneficial input to the design. 2. The enhanced ability to accelerate the project’s delivery schedule. 3. Enhanced cost certainty at an earlier point in design than DBB. 4. The ability to bid early work packages as a means to mitigate the risk of construction price volatility and accelerate the schedule. 5. Owner control over the details of the design. Table 2 shows that the four most frequently cited dis- advantages are: 1. Reconciling the conflict between the primary motivations of the CMR and the designer (i.e., cost control versus conservative design to reduce design liability). Advantages (ref. no.)

13 2. That the owner must still administer/coordinate both a design and a construction contract. 3. The final actual cost is not known until the GMP is established. 4. Agency personnel are trained to properly implement CMR project delivery. Project Delivery Concepts Figure 5 is taken from a textbook on alternative project delivery and graphically illustrates the “three legs of a fair and stable contract” (Gransberg et al. 2006). The five primary advantages cover the three legs of the project delivery process: cost, schedule, and quality. On the other hand, the previously mentioned four disadvantages are basically linked to the con- tract administration process associated with implementing CMR. This is an interesting dichotomy that will be explored in detail in the following sections. Looking at the three major project delivery methods allows the comparison of how each of the three legs is fixed in each method to create a fair and stable contract. In DBB, the quality and schedule legs are fixed by the contract completion date and the construction documents on which the contractors bid. Therefore, cost is the variable leg with the bids showing how much it will cost to deliver the specified quality within the specified time. In DB, the schedule remains fixed by contract and the cost leg is fixed by the design-builder’s lump sum proposal. Therefore, quality is the variable leg in the stool and as a result the owner no longer controls the details of design. In CMR, the contractor is brought to the project during design and helps optimize all three legs of the stool before they are fixed. Thus, CMR holds potential for developing the high degree of collaboration necessary to maximize quality within the project’s time and cost constraints without the interference of the contracts. Quality Aspects of Implementing CMR Two of the major cited advantages deal with quality: con- structor design input and owner design control.

constructor is formally included in the design process: “Con- tractor experience and expertise can aid the design team in preparing more cost-effective traffic control plans, construc- tion staging plans, and perhaps more realistic construction schedules” (Anderson and Damnjanovic 2008). Chapter five of this report will discuss preconstruction services in detail. Two of the services performed by the CMR during the design phase are constructability reviews and design validation. Con- structability is defined by the Construction Industry Institute as “the integration of construction knowledge and experience in planning, design, procurement, and construction phases of projects consistent with the overall project objectives” (“Proj- ect Delivery Systems . . .” 1997). One of the papers cited in Tables 1 and 2 provides useful advice for appropriately timing reviews: Constructability is achieved through the effective and timely integration of construction input into planning and design as well as field operations. For maximum effect, it should be initiated early in the design process and performed at predefined points during the design process in accordance with a well thought-out plan (Martinez et al. 2007). This quote argues for selecting the CMR early in the design process to gain the “maximum effect” or benefit from the constructors’ knowledge and experience before design effort is wasted developing potential alternatives that need to be changed as a result of the budget and constructability reviews. Another paper that reports on a successful CMR stormwater drainage project in Florida confirms this assertion and goes on to describe the benefits: The ability of the CM to input constructability reviews, construc- tion phasing, material availability, and cost estimating throughout the design process reduces the probable occurrences of change orders, project construction delays, and increased project costs due to contractor identification of these elements in the design phase instead of the construction phase (Kwak and Bushey 2000). The above discussion leads to the idea that the constructabil- ity process adds value to the project by enhancing the quality of the design and driving it to produce a buildable project (Jeargas and Van der Put 2001; Dunston et al. 2002). An NCHRP study (Russell et al. 2002) found that one of the major research issues in the transportation sector was implementing a constructability review program in the planning and design phases that focuses specifically on “deficiencies in quality and clarity of construction plans.” It went on to recommend research on how to leverage constructability reviews as a means to increase the speed of construction. “The constructability review process, therefore, is recommended as an indispensable means toward achieving quality in the delivery of transporta- tion projects” (Dunston et al. 2002; italics added). Design validation is not a technical peer review of the design by the constructor. One author stated: “[t]he con- struction manager is not the licensed architect or engineer for the project and should avoid comments in the constructability reports that would more properly be included in a peer review 14 by design professionals” (Martinez et al. 2007). That paper goes on to recommend that design validation reviews by the CMR be limited to “. . . industry standards, previous con- struction experience with similar designs, and previous expe- rience related to re-work or warranty issues.” Thus, design validation becomes the process of reviewing the design prod- ucts to confirm that they can indeed be built as depicted and that they conform to available means, methods, and materials. A complex tunnel project in Portland, Oregon, was delivered by CMR and the owner reported measurable benefits as a result of the “contractor’s early involvement with design review, value engineering, and risk analysis prior to design completion . . . which contributed to significant cost and schedule savings” (Gribbon et al. 2003). The benefits of design validation reviews are confirmed by another paper that reported that CMR project delivery “provides for flexibility in the implementation of design changes late in the design process without impacting construction schedules and final delivery dates” (Kwak and Bushey 2000). The bottom line is that “[q]uality [construction] documents facilitate quality construc- tion and good relations with the construction industry, and projects delivered cost-effectively without extended duration greatly enhance public image for the STA [state transportation agency]” (Dunston et al. 2002). To accrue these potential advantages, the owner can develop a process that manages the greatest disadvantage reported in the literature. This is the reconciling of the differing agendas of the CMR and the designer during design. By con- tract, the CMR is cost-focused during the design phase because the primary reason for an owner to select CMR project delivery is to have access to real-time cost estimating capability that exists only in the construction industry (Martinez et al. 2007). Thus, the owner’s primary charge to the CMR is to ensure that the project does not exceed the budget. On the other hand, the owner charges the designer with ensuring that the project design details conform to all applicable codes, laws, and regulations while at the same time furnishing the desired technical capabilities and capacities. If the project does not meet these requirements, then the designer is liable to cor- rect the problem. Additionally, the designer’s liability for a structural failure in the project tends to last longer than the builder’s. As a result of this issue, designers tend to be con- servative in their designs, which can cause the construction cost to push against budget limits. Doren et al. (2005) pro- vides a list of quality imperatives to be satisfied to reconcile the competing agendas: • Need to pay more attention to controlling scope; • A/Es [designers] need to be more conscious of the cost to build their designs; • More coordination/collaboration among team members; • There needs to be a thorough review of the technical design details; • Need to bring contractors, subcontractors, and suppliers on board in the design phase; and • Need quality reviews from CMs (Doren et al. 2005).

15 To accomplish this task it is necessary that both the CMR preconstruction services contract and the engineering design contract have language that makes “coordination/collaboration among team members” an explicit contractual requirement. The Memphis Shelby County International Airport solved the problem of conflicting agendas by adding a clause in their design contract that puts 10% of the design fee at risk for the quality of the construction documents (measured by the number of design changes made during construction owing to errors and omissions). It stated that this effectively changed the engineers’ attitude from seeing the CMR constructability and design validation reviews as unwanted criticism to seeing the reviews as a valuable component of the design quality management program (Touran et al. 2009a). This also under- scores the need to modify the design contract to facilitate the preconstruction services provided by the CMR. Although chapter seven will discuss the quality manage- ment process in detail, it can be seen from this discussion that CMR provides a mechanism to enhance the quality of the design that necessarily translates into better construction quality owing to increased constructability (Dunston et al. 2002). This is confirmed by four of the papers cited in Table 1 that reported that CMR created a “focus on quality and value” rather than minimizing cost. This is nicely expressed by Dunston et al. when they state: “[t]he message is conveyed that the standard for top performance is measured by quality in terms of biddability, buildability, and maintainability in the project rather than by merely meeting a predetermined schedule” (Dunston et al. 2002). And this leads to the dis- cussion of schedule issues in CMR project delivery. Schedule Aspects of Implementing CMR The second major advantage of CMR project delivery was cited by 10 of the authors reviewed for this report and it deals with the enhanced ability to accelerate the schedule. As with DB, CMR projects do not have to wait for the design to be complete. A careful reading of the literature shows the “construction process” defined to include the procurement activities that a contractor undertakes once it has a signed contract to arrange for materials and subcontractors (Alder 2007; Gambatese et al. 2002). The primary benefit comes from the ability to arrange the work in bid packages that correlate directly with design packages. This permits the CMR to bid out those packages as soon as each package’s design is ready. This also allows the construction to begin before the entire design is finished without burdening the budget with unnecessary contingencies for possible design scope creep. These budget benefits will be discussed in the next section. To effectively accelerate the delivery period, the owner forms both the design and the construction contracts with this goal in mind. It cannot assume that the two can run independently and achieve this mutual goal. “The construction manager should review the overall project schedule and conduct coordination meetings with the design professionals to make sure the design activities are in compliance with and integrated into the construction sched- ule” (Martinez et al. 2007). This issue speaks to the second most often cited disadvantage, which is the owner’s need to properly coordinate and administer two contracts as opposed to the single contract in a DB project. It also advocates con- tractually assigning both design and construction scheduling responsibilities to the CMR. Doing so would ameliorate the cited disadvantage of “lack of clear leadership during design” by requiring the engineer to coordinate its efforts through the CMR for the best interests of the overall project’s schedule. If the design contract does not have this type of language, the owner regresses to dealing with the major disadvantage of refereeing the different agendas of the designer and the builder. Managing schedule risk is always significant in transporta- tion projects and especially so when the project will disrupt the traveling public for significant periods of time. Trans- portation agencies are always looking for ways to reduce design and construction schedules (Ford et al. 2004). One way to manage this risk is to begin design and construction activities as soon as they can technically be started and to maximize the number of parallel activities that occur in the schedule (Touran 2006). As the CMR ultimately is at risk for delivering the completed project on time, it makes sense to involve it in the risk analysis. Touran puts it this way “. . . the CM is the entity who should be performing the risk analysis. The owner can benefit from an experienced construction manager that is present in the project since the beginning and understands the implications of various decisions regarding scope, budget, and schedule . . .” Thus, it appears to be impor- tant that the CMR’s preconstruction services contract be spe- cific about its roles and responsibilities for scheduling during design. Kuhn puts it this way: Preconstruction phase schedule management is one of the key roles of the [CMR’s] preconstruction manager. Creating a real- istic and detailed schedule for all design, approval, estimating, and purchasing activities to ensure that construction activities begin on schedule is the primary objective of the preconstruction schedule. The preconstruction schedule reflects what is expected of the design team, CM, and owner so that packaging and scoping of the work can be accomplished through documents that address required information at each stage of the design process. For this reason, it is critical that the preconstruction manager be involved in the project as early as possible to coordinate deliverables and expectations with the design team (Kuhn 2007). UDOT’s CMR implementation experience confirms that the schedule advantages found in the literature can be realized in the field. This agency cites a number of reasons why they believe that CMR project delivery allowed them to accelerate project schedules but warns that this advantage does not come to the owner risk free: The CMGC [CMR] process has reduced the schedule for most projects. Part of the reason for this is the time saved in the design effort. The contractor’s participation helps to identify solutions quickly and speeds up the design process. Their participation also reduces the detail that must be communicated to the contactor

in drawings and specifications. CMGC in general allows a project to begin at risk. One project began before the railroad right of way issues were cleared . . . By careful construction planning the railroad work was saved for last and right of way issues were cleared in time to complete the project on schedule. Choosing a contractor in the design process also helps to clear utility issues. Utility companies move more quickly to plan and execute solu- tions when they know the contractor they will be working with. Phasing helps to reduce schedule time. Long lead items were purchased during design that would be used later in construction. This is not without some risk (Alder 2007; italics added). The old cliché that time equals money operates in this project delivery method. The risk of not finishing on time almost always results in additional hard costs to the agency and increased user costs to the traveling public. “While sched- ule risk assessment can be performed without regards to cost in most cases, calculation of cost risks has to be tied to schedule” (Touran 2006). This leads to the subject of the next section. Cost Aspects of Implementing CMR Two of the top five CMR advantages were directly related to cost. First, the owner is able to achieve cost certainty earlier in CMR than DBB because the constructor is furnishing esti- mates during design, as well as a GMP before 100% design completion. Additionally, the owner can choose to use a pro- gressive GMP where the CMR commits to incremental bid package GMPs as design packages are complete and finalizes the project GMP when the majority of the work has been bid out to trade subcontractors and material suppliers. This reduces the risk to the constructor and the amount of contingency that the CMR maintains against the cost risks of material price escalation, subcontractor availability, and scope creep during design. The second advantage deals with the role of the GMP as an incentive to control costs. That the CMR is allowed to provide design input and then prepares progress estimates based on that input creates “buy-in” to the final design by the CMR. “If the CM At-Risk has been on board all along, [it] will find asking for changes because of ambiguities in the plans as difficult as ever” (Strang 2002). These benefits are offset in the literature by the require- ment to select the CMR early in the project development process and then wait until the design progresses to the point where a GMP can be established without excessive contin- gencies before the actual total cost is known to the owner. Although this is earlier than in DBB, a lump sum DB project fixes the design and construction costs at award. One of the other cited disadvantages is that the designer is not obligated to incorporate the CMR’s design recommendations into the final design. SYNTHESIS METHODOLOGY The methodology was designed to analyze the output from multiple study instruments to identify intersections between the literature, information found in the case studies, points 16 derived from the structured interviews of agencies, a survey of state DOTs, and the content analysis of CMR solicitation documents. Finally, structured interviews with contractors who have completed the case study CMR projects were con- ducted to validate the conclusions. The conclusions reported in the final chapter are the result of triangulation between three or more of those sources. Effective practices and lessons learned discussed at the end of each chapter are drawn from the intersection of the literature and one of the other study instruments. Thus, the rationale for developing conclusions and effective practices is to be able to map them back to two or three sources that all agree and further validate them by indicated construction industry confirmation. Information for synthesis development was collected using the following study instruments: 1. Review of the current literature; 2. Surveys using a web-based questionnaire to state high- way agencies and other transportation agencies to identify those with CMR experience; 3. Structured interviews with DOTs and other public trans- portation agencies with CMR experience; 4. Content analysis of RFQs/RFPs for CMR transportation projects; 5. Case studies of DOTs and other public transportation agencies that have implemented CMR; 6. Case studies from the transit, airport, and building sectors; and 7. Structured interviews with members of the construction industry. Literature Review All relevant literature was reviewed. Special attention was paid to national and international experience as it may apply to state-level projects. The literature review was used to prepare the survey of state DOTs to ascertain which agencies have actual CMR experience. Additionally, the literature was used as a basis to prepare the case study structured interview questionnaires. The industry structured interview question- naire was also prepared based on information found in the literature review. Finally, the review also looked for parallel case studies from the architectural sector to permit a com- parison of vertical building projects with horizontal transporta- tion projects. These were used to compare the information gained from DOTs that reserve CMR for the delivery of projects with a strong vertical component such as multi-modal centers, airport terminals, and rest areas (i.e., Alaska and Florida). National Survey A short survey was uploaded to a commercial Internet sur- vey site (see Appendix A for details). The consultants then

17 e-mailed the state construction and design engineers for each DOT and requested that they visit the link on the survey and complete the survey. The purpose was to identify those state DOTs with CMR experience. Figure 6 shows the response rate and the results in a graphic manner. One can see in Figure 6 that five states have some experi- ence with CMR project delivery. The Rhode Island DOT is overseeing a CMR project for the Rhode Island Airport Corporation under the auspices of Special Experimental Proj- ects Number 14 (SEP-14). The Michigan DOT (MDOT) is also overseeing a CMR project to construct a passenger ship terminal for Detroit Wayne County Port Authority. Neither of these DOTs has attempted to procure a typical highway project using the method. The survey response from Rhode Island indicated that the DOT did not have CMR contracting authority, and this is interpreted to mean that it can only use the method via the SEP-14 authorization. Michigan is different in that it does have the ability use the method, but the structured interview with the MDOT project manager indicated that the agency had not yet found a traditional highway project where CMR project delivery made sense. Of the states shown in black in Figure 6, Arizona, Florida, and Utah have the most experience. The Florida DOT (FDOT) has largely used the method to procure transporta- tion projects with a strong component of vertical/building construction, including a $1.3 billion multi-modal center in Miami. The Arizona experience is largely at the county and municipal level, where the local agencies in and around the Phoenix metroplex have a robust and long-standing CMR project delivery program. Arizona DOT has awarded two CMR projects that are underway at the time of this writing. UDOT has the nation’s greatest experience in using CMR (termed CMGC in the literature from Utah) project delivery for typical road and bridge projects. UDOT has a memoran- dum of understanding with FHWA for 24 CMR projects authorized for federal funding with additional CMR proj- ects planned to be funded solely by the state. Of that group, 13 are completed and another 16 are underway. Given this breadth and depth of experience with projects that are of prime interest to this synthesis, the Utah input from the various study instruments is given the most weight in the analysis. A member, UDOT, expressed the opinion stated here. However, UDOT has not adopted this as its policy and continues to select project delivery methods on a project- by-project basis. Use CMGC [CMR] as the primary delivery method unless sched- ule is the principle driver. When a shortened delivery schedule is the primary motivation design build should be used. If the [CMGC] contractor cannot deliver the project for a fair price then the fall back position is [Design] Bid Build. I make this recommendation because we should always want the contractor’s input to reduce risk, cost, and construction time (Alder 2007; italics added). The remaining two states, Alaska and Oregon, have limited experience. The Alaska DOT experience is much like FDOT’s in that it has completed two airport terminal expansion projects and both had a large proportion of vertical construction. The interview with the project manager in Alaska indicated that the agency is looking to expand the use of CMR to road and FIGURE 6 National survey of DOTs’ results (note: unshaded states did not respond).

bridge projects, but will first deal with policy and procurement culture issues. ODOT is using CMR to deliver a major inter- state bridge project with thorny environmental issues, and plans to continue its use of the method based on the positive experience with the first project. Of the states that have authority but have not tried CMR, Nevada and Washington State, are actively pursuing the nec- essary tasks to implement it on a pilot basis. As with Michigan, Washington has not yet found a project that it believed would make a decent pilot project. Nevada received its authority in 2008 and has just embarked on the development of its pro- gram policy and procedures. Colorado and Wyoming both answered the survey by indicating that they had not yet had a project where CMR project delivery made sense. Texas stated that it did not believe that CMR project delivery was appro- priate for horizontal projects. Structured Interviews The primary input to the case studies was gathered through structured interviews with the agencies that had implemented CMR project delivery. The structured interview outlines were developed on lines similar to the method prescribed by the U.S. Government Accounting Office (“Using Struc- 18 tured Interviewing Techniques” 1991). The agency method states that structured interviews can be used where “infor- mation must be obtained from program participants or mem- bers of a comparison group . . . or when essentially the same information must be obtained from numerous people for a multiple case-study evaluation” (“Using Structured Interviewing Techniques” 1991). Both of these conditions apply to this synthesis; therefore, the tool is appropriate for the study. Agency Interviews The structured interviews of the agencies with CMR experi- ence were centered on a single case study project. However, the interview was broadened to include a more general set of policy, procedure, and effective practices for those agencies that had completed several CMR projects. A total of 10 agen- cies were interviewed either face-to-face or telephonically, depending on their availability. The total value of the case study CMR projects associated with these agencies is $2.3 billion. Table 3 shows the salient details on each agency interviewed. This list constitutes most of the DOTs with some sort of CMR experience. It also includes two non-state transporta- tion agencies with significant CMR experience. The list also covers a wide range of project sizes, from a low of $10 mil- Agency CMR Experience (no. projects) Case Study Project Location Size ($) Primary Type Alaska DOT&PF 2 Fairbanks Intl.

19 lion to a high of $1.3 billion. It also covers nearly all modes of transportation. Contractor Interviews It is extremely important for this study to gauge the perception of the construction industry on this particular topic. These stakeholders are directly affected by any change to the require- ments for bidding on public works contracts. The contractors who won the CMR contracts on the case study projects were interviewed (see Table 4 for details). They represented both large and small companies as well as local, regional, and national areas of operation. Three of the contractors had CMR experience with more than one highway agency. All the con- tractors interviewed expressed a strong positive perception regarding their experience with CMR. This included one national contractor that had won the first two CMR projects that were advertised by a given DOT. Solicitation Document Content Analysis The content analyses of public transportation solicitation doc- uments was conducted to create a basis for identifying CMR effective practices and to quantify the state of the practice regarding the procurement phase of CMR projects. The con- tent analysis consisted of gathering and reviewing solicitation documents and searching for the requirements for qualifica- tions that were outlined in the documents. The formal content analysis furnishes quantitative measurements of current DOT requirements for CMR selection factors. They are found by counting the number of times that specific terms of interest are required to be submitted by contractors to be considered for the project. This type of analysis can be used to develop “valid inferences from a message, written or visual, using a set of procedures” (Neuendorf 2002). The primary approach is to develop a set of standard cate- gories into which words that appear in the text of a written document, in this case the structured interview questionnaire, can be placed and then the method uses the frequency of their appearance as a means to infer the content of the document (Weber 1985). This allowed an inference to be made regard- ing the given owner’s approach to CMR selection. When the results are accumulated for the entire population, trends can be identified and reported. The output from the content analysis can then be compared within the population to determine how CMR selection policy is being implemented in project-specific solicitation docu- ments. The output can also be compared with the responses from the survey and structured interviews to map respondents’ output against their respective agency policy and solicitation documents. There are three types of solicitation documents: Requests for LOI, RFQ, and RFP. LOIs are defined as documents that merely ask contractors to respond indicating their desire to compete for a CMR without requiring them to submit a list of specific qualifications or cost information. RFQs require contractors to submit their qualifications, past experience, and other evaluation factors, but do not require any cost or pricing information. RFPs require submission of cost or pricing information in addition to other evaluation factors such as qualifications, past project experience, and schedule. Figure 7 shows the geographic distribution of the content analysis. Table 5 is a summary of the content analysis popu- lation.

project from 8 different states were analyzed. Additionally, 29 documents from 12 states related to non-transportation projects were analyzed. The content analysis includes docu- ments from a wide range of monetary value, $2.25 million to $2.16 billion for transportation projects and $1.2 million to $114 million for non-transportation projects. Case Studies The primary source of information in this synthesis is the analysis of case studies. The analysis occurred on the follow- ing three levels: 1. Analysis of CMR highway road and bridge projects. 2. Analysis of corresponding public transportation agencies with CMR experience. 20 3. Analysis of case study projects from the airport, transit, and building sectors. The case studies were collected using Yin’s methodology for case study research data collection (Yin 1994). Therefore, the information gleaned from the case studies is coupled with information collected in the survey and the literature review to validate any conclusions drawn from the case studies. Note the case study information was gathered by both face-to-face and telephone interviews. CASE STUDY SUMMARY Case study data were collected based on the results of the literature review. The team proposed to identify and analyze at least four projects from across the spectrum of highway FIGURE 7 Locations of solicitation documents used in the content analysis.

TABLE 5 SOLICITATION DOCUMENT CONTENT ANALYSIS SUMMARY

21 projects that had been delivered using the CMR project deliv- ery method. The team was able to identify and gain access to information on ten projects worth more than $2.5 billion from nine agencies that represent the cross section of variations on CMR delivery. It is important to note that, to the best of our knowledge and confirmed by the survey, every state DOT with some form of CMR experience was contacted. The projects ranged from a low of $10.0 million to a high of $1.35 billion. The project types spanned the upgrade of pedestrian/bicycle access on an urban thoroughfare to a green- field freeway to a billion dollar multi-modal terminal facility. Two different sets of contract responsibility were also found. The first is classic CMR delivery where the DOT holds both the design and the CMR contracts, and the second set involved the DOT in an oversight relationship on behalf of another agency that furnished the funds. Additionally, another enhance- ment to the original study plan was realized when the team was able to identify CMR projects where a state DOT actually delivered multi-modal facilities that interfaced with airports and seaports, as well as rail and light rail. Finally, case studies from the airport, rail transit, and building sectors are presented to allow the reader to compare and contrast the variations on CMR across these industry sectors with the cases from the highway sector. The depth and validity of each agency interview was enhanced, where possible, by an interview with the contrac- tor that held the CMR contract. This allowed the collection of information that compared and contrasted the owner’s per- ceived benefits and constraints with a parallel set of benefits and constraints perceived by the contractor on the same proj- ect. Table 6 is a summary of the case study projects that were sampled for this report. One can see that the projects span from coast to coast but tend to be concentrated in the south- western United States. Details of each case study project are contained in Appen- dix C.

RATIONALE FOR CHOOSING CONSTRUCTION MANAGER-AT-RISK PROJECT DELIVERY The structured interviews asked each agency to explain their rationale for selecting CMR project delivery. First they were asked to identify the factors that they consider in making the project delivery selection decision and next they were asked to identify the reasons they selected CMR for the case study project. Tables 7 and 8 show the output from those questions. An analysis of Table 7 shows that the six major factors that are considered by at least eight agencies in their project delivery method decision are: 1. Monetary size 2. Budget control issues 3. Schedule issues 4. Technical complexity 5. Project type (typical agency project or nontypical agency project) 6. Project type (bridge/structure or road). 22 This shows that the agencies are considering alternative project delivery methods as a means to better grapple with the requirements of budget and schedule, as well as use project type and complexity as decision criteria when making the project delivery method decision. The table also shows that the main factors (at least five cites) that tend to drive that decision toward CMR are: 1. Schedule issues 2. Technical complexity 3. Third-party interface issues. The driving factors are interesting in that they indicate that agencies are looking for constructor assistance in meeting aggressive schedules for complex projects where third-party stakeholders such as utilities, railroads, and permitting agencies could have an impact on the project’s success. The reason why CMR was selected for each case study project shown in Table 8 confirm this observation.

23 CONSTRUCTION MANAGER-AT-RISK PROCUREMENT PROCEDURES The study found that three different models are in use for procuring CMR projects. These will be discussed in detail in chapter four. Table 9 illustrates the content of each case study project’s solicitation documents. The striking thing is the simplicity of most of the solicitations. This shows the major difference between CMR and the other project delivery methods. Because the total construction cost is not part of the selection process, this permits the content of the solicitation documents to be relatively straightforward.

description of the project. Half the projects listed the roles and responsibilities of the CMR and the owner with regard to quality. To respond to the solicitation, each competing CMR pre- pares a submittal that incorporates all the information that the agency wishes to evaluate. As one moves from left to right in Table 10, the size of the proposal gets larger. The primary difference between the RFQ model and the other two models is the lack of cost information. Thus, in the RFQ model, the agency is selecting its CMR solely on a basis of qualifications and past performance. This is the way design professionals are typically selected. It is noted that there are no obvious differences between the highway and non-highway agency case study require- ments in the previous four tables. Therefore, it appears that highway agencies can use examples from other transporta- tion and building sectors in their states. Specifically, com- paring UDOT and Utah Transit Agency (UTA) shows that whereas there are differences in the content of their solic- itation documents and proposal submittal requirements, those differences are not skewed to or away from any single category. 24 Once the submittals are received, the CMR selection process begins. In all cases, it was composed of an evaluation of the written statement of qualifications (SOQ)/proposal and an interview/presentation made by the competing CMRs. Table 11 shows the difference between each case study agency’s selection process. It shows that most keep the pre- sentation focused on the CMR’s qualifications and experience. There is also strong preference to direct point scoring and weighted categories to determine the winner. Price was also used as a selection factor by four of the five RFP agencies. CONSTRUCTION MANAGER-AT-RISK PROJECT ADMINISTRATION The major element of CMR project administration is the decision to establish the GMP. This aspect will be discussed in detail in chapter six. Table 12 shows how each case study project compares with regard to the type of contract used, the timing of the GMP, and the way contingencies were handled. The progressive GMP system allows the CMR to price work and bid out work packages as soon as they are complete. This allows construction to begin before design is complete with- out forcing the CMR to include a large contingency for the undersigned features of work.

PRECONSTRUCTION SERVICES The ability to involve the contractor in the design phase occurs through the preconstruction services contract. This will be discussed in detail in chapter five. Table 13 shows how each case study agency configured the services it wanted from the CMR. The table shows that scheduling, estimating, and con- structability reviews are the most prevalent preconstruction 26 services. Additionally, value analysis and coordination with third-party stakeholders are also very common to these contracts. SUMMARY The salient aspects of each case study will be compared and contracted in the remaining chapters of this report.

TRB’s National Cooperative Highway Research Program (NCHRP) Synthesis 402: Construction Manager-at-Risk Project Delivery for Highway Programs explores current methods in which state departments of transportation and other public engineering agencies are applying construction manager-at-risk (CMR) project delivery to their construction projects.

CMR project delivery is an integrated team approach to the planning, design, and construction of a highway project, to help control schedule and budget, and to help ensure quality for the project owner. The team consists of the owner; the designer, who might be an in-house engineer; and the at-risk construction manager. The goal of this project delivery method is to engage at-risk construction expertise early in the design process to enhance constructability, manage risk, and facilitate concurrent execution of design and construction without the owner relinquishing control over the details of design as it would in a design-build project.
