The agency is currently identifying and acquiring between 15 and 25 sites for the scheme. The contract includes construction and design services, as well as facilities management, demolition and maintenance works.
In an advertisement inviting expressions of interest in the European Union's Official Journal, the agency said: "SEEDA wishes to procure a range of development and property services … At this stage, it is the intention of SEEDA to meet all the capital costs for the acquisition of the sites, servicing construction and fit-out for each of the proposed buildings."
Up to nine teams will be invited to tender in January. The contract will be awarded on a value-for-money basis.
The move is part of SEEDA's regeneration drive, which includes the establishment of the UK's first brownfield land assembly trust last month.
