Transport for London is on the hunt for three contractors to carry out £500m of major roads work in London over the next four years.
Contractors and consultants will be expected to bid in joint venture for the framework, which is part of TfL’s £4bn Roads Modernisation Programme.
TfL said this was because of the “strong design element of work” in the framework.
The winners will carry out design and construction works for the enhancement or refurbishment of London’s highways, structures and tunnels.
This will include cost planning and management, risk identification and mitigation, and early investigation work.
Construction activities will include the main civil works, in addition to temporary works, utility diversions and ancillary works.
The contract will span four years with the option to extend for an additional two, due to the complexity of some of the schemes.
Construction firms have until 11 July to express an interest to bid.
