The board approved a $37.5 million construction manager/general contractor agreement with Kiewit Corporation for Task 1 (liner raise from Milepost 3.5 to 7.2) of the Delta-Mendota Canal subsidence correction project. The original cost estimate based on Reclamation's 30% design was $19.75 million, but challenges including high-voltage power line proximity, dispersive borrow soils requiring geotechnical fabric, and safety requirements drove costs up. Staff negotiated Kiewit's initial $46 million proposal down to the final $37.5 million. Construction notice to proceed is targeted for June 19.
