San Diego-based Contractor's Bid Apparent All-American Canal Winner
Award is expected by the end of May of a contract for two reaches of the All-American Canal near California's border with Mexico following a March 22 bid opening by Imperial Irrigation District (IID). San Diego-based Ames/CSI is the apparent low bidder at $8.187 million for both sections. Other bidders include Alamo, Calif.-based R&L Brosamer Inc. at $9.2 million; Vancouver, Wash.-based Kiewit Pacific Co. at $16.16 million; and Bozeman, Mont.-based Barnard Construction Co. Inc. at $20.968 million. By replacing 23 miles of the 82-mile unlined canal built about 1900 with concrete-lined canal, the work will stop 67,700 acre-ft of seepage from the 3.1 million acre-ft of Colorado River water that flows through it each year.
Construction requires excavating a canal prism from the sand and running a paving train to place the concrete, insert joints and apply a curing compound. It will require 4.7 million cu yd of earth excavation, 375,000 sq yd of 4-in.-thick concrete, 600,000 sq yd of PVC geomembrane lining and some dewatering for transition structures. Work could start in the summer and be complete in 2008.
