Costain and Transport for London have started a major upgrade programme for the Brent Cross Interchange in North London.
The work will fall under one of the four work packages in TfL’s STIP 2 – Structures and Tunnels Investment Portfolio 2.
The portfolio is a programme specifically to deal with old structures that have historically needed high levels of maintenance, but are also critical to travel around London. Hammersmith Flyover was another of the structures in the portfolio. The intervention aims to ensure structural safety and perform significant upgrades and repairs so that less maintenance is needed in the future.
The construction of the interchange was completed in 1967 and it includes 19 bridges, a flyover, subways, culverts and retaining walls. It is on the North Circular Road at the junction with the A41.
“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 Costain project manager Marcus Hollan.
“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 will being in 2018 and be completed by 2021. It is part of the wider Brent Cross Cricklewood Regeneration project that will provide further road upgrades in the area to increase capacity.
