Birmingham City Council is on the hunt for a contractor to carry out renovation and expansion work on Alexander Stadium to prepare it for the 2022 Commonwealth Games.
The Alexander Stadium, in Perry Park, will host both the opening and closing ceremonies as well as the athletics events for the 2022 Games.
Arup is already working on the designs for the revamped venue, while Mace has been appointed as project manager for the council.
The capacity of the stadium will be increased from 12,700 to 40,000 and 20,000 seats will be retained after the event.
The revamped stadium will also include new community sports facilities within the new stand, a permanent warm-up track and a new conference meeting space created to host business and cultural events after the Games.
The venue is more than 40 years old and is the administrative home for UK Athletics.
A new 15,000 seater west stand will be built and additional seating installed in the north and south stands.
