Connect Plus – M25 DBFO program

Connect Plus – M25 DBFO program

London, United Kingdom

Client: Highways Agency

Parsons Brinckerhoff Role: Asset Management and Highways Modeling

 Show Project Details

The Connect Plus consortium is delivering a 30-year asset renewal program for the M25, A282 Dartford Crossing and key arterial routes serving London.

As part of the Highways Agency’s $10.4 billion (£6.2 billion) wider Design, Build, Finance and Operate (DBFO) program, the renewal activity will ensure journey time reliability and safety standards are maintained.

In its fourth year, the consortium delivered its most challenging project: the widening of the M25 between junctions 16 and 23 and between junctions 27 and 30 in time for the London 2012 Olympic and Paralympic Games. These vital works were completed ahead of program and with appreciable cost savings.

“I have been impressed with the real commitment and collaborative working by your staff. It has been a tough job, but one well done. To everyone who contributed - thank you." Graham Dalton, Chief Executive, Highways Agency.

In addition, within the program, we developed innovative strategies for fast pavement replacement and have also delivered simulation models to analyze different operational scenarios for the proposed free-flow charging system at the Dartford Crossing.

About Operations & Maintenance

Parsons Brinckerhoff is a leading provider of operations and maintenance (O&M) services for a wide range of infrastructure assets worldwide, including transportation systems, power plants, and buildings and facilities. Our O&M services are enhanced by more than a century of experience in the planning, design, and construction of all major forms of infrastructure. Our understanding of how an infrastructure asset changes over its life cycle—whether it is a highway, bridge, tunnel, transit system, building, or power station—provides a critical perspective in developing an effective O&M program that will promote safety and efficiency, and reduce long-term operating costs.

Our services include management of condition assessment and inspection programs; maintenance management and training; development of facility management and maintenance programs; and energy management. Our O&M projects range from maintenance of roadway networks for the Highways Agency in the UK, to energy management for major buildings in Asia, to management of large-scale building condition assessment programs in the U.S. We developed condition assessment survey procedures and created deficiency-standards handbooks for one of the largest facility survey programs ever conducted by the U.S. government, involving 10,000 buildings as well as structures and equipment.

Whether provided as stand-alone services, or part of a suite of services supporting project delivery and operation, Parsons Brinckerhoff’s O&M services assist clients in protecting vital—and expensive—infrastructure assets and extending their operational life.
