Construction Claims due to Difficult Muck Excavation at the Twin Lakes Dam Enlargement Project
The Twin Lakes Dam Enlargement project, located in Northern Wyoming, was completed in 1998. Foundation excavation for the embankment dam required removal of deep peat bog deposits. The excavation depths and bid quantity were estimated based primarily on hand probe data, with an additional amount added to allow for uncertainty. Due to strong competition, the successful bid for construction was substantially lower than the Engineer's Estimate. The low bidder planned to complete the work in a single construction season, about half of the duration estimated by the Engineer. During construction, much deeper than expected peat bog deposits were encountered. This impacted the schedule, and the Contractor eventually took three full seasons to complete the project. Ultimately, the Contractor negotiated additional compensation for increased costs associated with the muck excavation, including delay impacts and inefficiencies. However, even with large increases from the low bid price, the final construction cost was within 10 percent of the original budget estimate.
