In June, Tampa Bay Water expects to select either Granite Construction Co., Kiewit Infrastructure South or Skanska USA Civil Southeast as the design-build-maintain contractor for the cracked C.W. Bill Young Regional Reservoir. Ranging from $120 million to $170 million, the three recently received bids are to repair the soil-cement erosion-control layer and expand the reservoir by about 40%. Notice to proceed for permitting is scheduled for Sept. 1, with a construction start anticipated a year later. About 12 months after its 2005 opening, cracks began forming in the 15.5-billion-gal reservoir, designed by HDR Engineering and built by Barnard Construction.
