The emergency repair to the Wanapum Dam was intricate, involving a lot of equipment and resources. The techniques incorporated included high-capacity post-tension strand anchors, underwater bar anchors, and many types of grouting. The first milestone was raising the pool level to be able to increase power generation. Plus, the work was vital to the success of the salmon population in the region.
What makes it interesting?
A crack was discovered in the Wanapum Dam in February 2014, and the water level was immediately dropped to relieve pressure on the cracked area. Officials trying to find out what caused the crack discovered an error in original design calculations, which meant repairs were required across the entire dam.
How HCSS Software assisted with this project
HeavyBid allowed Nicholson to accurately estimate costs, crews, and equipment. Its versatility has allowed Nicholson to change and add elements to the project as it has progressed and grown from a $100,000 job to over $20 million.
