Four contractors are in the running for a £45m office development at Birmingham Snow Hill rail station.
Client RT Group Development (RTGD) is understood to be looking at bids from BAM Construct, Balfour Beatty, John Sisk, and Sir Robert McAlpine.
RTGD is a wholly owned subsidiary of developer Ballymore.
The scheme is the second of four phases in the development of the site, where RTGD owns 1.86 hectares of land.
The first project (pictured) was completed by Kier and is already occupied.
Work on the second phase was suspended during the recession after original backer Anglo Irish Bank pulled out. It left the scheme half-built, with two concrete cores sticking up into the skyline.
However, after selling its interest in the first phase for £126m earlier this year, RTGD is now planning to complete the project.
The 14-floor office development will comprise 310,867 sq ft of office space and is expected to be completed in late 2012.
Law firm Wragge & Co has agreed a pre-let deal for 60% of the building.
A third planned phase of the Snow Hill scheme, which includes a hotel and a 44-storey residential tower, looks set to remain on hold.
