Up to five major industry players will be shortlisted for the shell and core contract which will take 32 months to complete.

The deal means the Olympic Stadium will not re-open until 2016 at the earliest.

West Ham United are currently preferred bidder for the stadium but the contract notice is deliberately vague about future uses.

It states: “The Stadium will become the new national competition stadium for athletics and has already been chosen to host the 2017 International Amateur Athletics Federation World Athletics Championships.

“It is the intention of the Contracting Authority that the Stadium will become a multi-purpose and multi-function venue that will be capable of hosting winter ball sports, athletics, and other sporting and cultural events.

“The Contracting Authority is seeking to deliver a commercially viable combination of uses that achieves both year round community access and delivers wider public benefits.”

The notice does not put a value on the conversion contract but confirms the £40m contribution by the London Borough of Newham.

Further contracts for work on the stadium will be tendered separately.

The notice states: “The Contracting Authority presently envisages procuring the following works via separate procurement processes: – internal finishes and fit-out works elements, which may include ceilings / walls / floors finishes, joinery and shop-fitting, washrooms and sanitary-related works, fixtures / fittings / equipment, signage / way-finding, audio-visual, and soft furnishings; – works to the warm-up track and community athletics facility, which may include earthworks, groundworks, in-situ concrete structures, below-ground services, above-ground external services, small buildings and structures, internal and external finishes, external hard and soft landscaping works, fixtures / fittings / equipment, signage / way-finding, audio-visual and testing and commissioning and final configuration works.”
