Keeping The Capital Moving

UK Highway at night

13 September 2016

Costain and Transport for London (TfL) are working to keep the capital moving.

Costain is working with TfL on maintenance to be carried out at the Brent Cross Interchange, one of four work packages in TfL’s STIP 2 (Structures and Tunnels Investment Portfolio 2). This programme is designed to deal with legacy structures that in the past have been challenging to maintain but which are critical to London's key routes. The aim is to make these structures safe and bring them to a good state of repair, so as to lower whole life costs and ensure they continue to serve London's people and economy.

Brent Cross Interchange is at the junction of the North Circular Road and the A41, near the M1 and next to the Brent Cross shopping centre. Built between 1965 and 1967, it comprises 19 bridges, a flyover, subways, culverts and retaining walls. It’s a strategic crossing point on TfL's Transport for London Road Network (TLRN) – the red routes at the heart of London’s road network that, although they make up only five percent of the capital’s roads, carry 30 percent of the traffic. 

“Transport for London (TfL) is focused on ensuring its roads and structures keep London working and growing. Part of this is to bring TLRN structures and tunnels up to a state of good repair and address specific safety risks,” said Marcus Hollan, Costain Project Manager.

“Our role is to support TfL by providing constructability input: that is, reviewing the construction processes from start to finish, advising on how to both operate in and accommodate the complex local environment, developing a comprehensive project budget and a principal programme, and carrying out risk evaluation.

“Key objectives of the first stage of this project are to establish the business outcomes and benefits that the project must deliver, and to secure project and financial authority to progress to the feasibility study as the next stage.”

He added: “Engaging STIP framework contractors like Costain in the very early stages of the project enables TfL to gain the most value for its money, to better understand the risks and to make sure of delivering the benefits and objectives on programme and on budget.

“What’s more, they are also making use of our extensive knowledge and experience from other STIP projects such as the successfully delivered Hammersmith Flyover.”

Work on site at Brent Cross will begin 2018 and is expected to be complete by 2021. The STIP works are being coordinated along with other work in the area including the Brent Cross Cricklewood Regeneration project, which will upgrade some of the highway structures at the junction to provide additional capacity.
