Wembley Stadium designer Mott MacDonald has claimed there were irregularities in the tender process which resulted in Multiplex winning the project.
It makes the claim in a 598-page document it has lodged at the Technology & Construction Court as part of its defence against a £132M claim from Multiplex.
Multiplex blames Mott MacDonald for the cost overruns and delays during construction of the stadium.
The document claims that Multiplex was privy to information and documents that had not been provided to the other contractors involved in the tender process.
The consultant claims that Tropus, which provided project management services to client Wembley National Stadium Limited (WNSL) until August 2001 and was part of WSNL’s negotiating team, had numerous concerns about the tender process and complained to the government that the quantity surveyor, Franklin & Andrews had not been consulted on drafting the Invitation to Tender letter of 14 July 1999.
