ST. PAUL, Minn. — A proposed Minnesota legislative office building that is being constructed on a tight timeline is headed back to the drawing board.

The Department of Administration said Monday it was canceling a previous selection process for picking a team to build it. The company was supposed to be chosen by now. Instead, the goal is to issue new guidelines and pick a builder by late September.

The $90 million building is supposed to go up behind the state Capitol and be done by 2015. Officials are under time pressure because the ongoing Capitol renovations will make much of that building a construction zone. Once completed, the new 154,000-square foot facility will have offices for state senators and their staff.

Department spokesman Curt Yoakum says the cost and timeframe shouldn't be affected.
