Minnesota lawmakers have been told that a final decision on a new Senate Office Building must be made within weeks or a related renovation of the state Capitol will cost more and take longer. The warning adds a new dimension to a politically charged debate over the office project. The building is supposed to cost $63-million with a separate parking complex increasing the project price tag by $27-million. Republicans are criticizing the Democrats who authorized it as supporting a lavish building. House Rules Committee approval of a design is the last known hurdle. Senators are due to move out of the Capitol by June 2015 during the long-planned renovation and relinquish space in the remodeled Capitol because of the new building.
