An OJEU notice published today is the first specialist package for the Olympic stadium conversion job which is expected to cost a total of £150m.
West Ham are preferred bidder for the stadium but its future is still unclear as funding wrangles continue over the conversion costs.
The club would not start playing in Stratford until 2016 at the earliest and a string of interim events have been planned including concerts and athletics meetings.
No value has been put on the roof and associated steelworks package for the stadium which 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 race for the main shell-and-core contract is currently under way with a winner due to be announced in December.
The roofing work will start before the end of this year and the contract will be be novated to the main contractor when they are appointed.
Contractors must register their interest by May 5 with London Legacy Development Corporation Level Ten, Stratford Place, 1 Montfichet Road Simon Matthews E20 1EJ Stratford UNITED KINGDOM +44 2032881800 firstname.lastname@example.org or online at www.supply4london.gov.uk
