Oroville Dam Spillway Cracking After $500 Million Repair
by Chriss W. Street29 Nov 2017Newport Beach, CA1,042 The California Department of Water Resources acknowledged this week that many cracks have appeared in the new concrete of the Oroville Dam spillway, which cost over $500 million to repair.
The State of California is believed to have spent $100 million each month on Oroville Dam during February, March and April in a crisis effort to try to stabilize America’s tallest dam, which suffered a near collapse and forced the evacuation of 200,000 downstream residents earlier this year.
The Kiewit Corporation, which was issued a $275 million contract in April to repair both of Oroville Dam’s main and emergency spillways, poured a 1,700-foot cement top sheet and then roller-compacted and smoothed the spillway’s surfaces shortly before the November 1 contract deadline. The California Department of Water Resources (DWR) inspected the work and certified the first phase of the massive repair job was completed on time.
