The existing wooded Flume 41 was built on hand-stacked rock built during the 1860s and is an important link in the El Dorado Irrigation District’s water conveyance system. The site is remote, very steep, and often requires the use of helicopters to deliver materails. The work to replace Flume 41 had to be completed during a shutdown of the entire system, during November and the first half of December. There was no relief for any weather impacts, which included snow. New mechanically stabilized earth walls were constructed and precast concrete flume sections installed and sealed. Significant slope stabilization involving rock anchors and shotcrete were installed prior to the shutdown of the flume system.
What makes it interesting?
This project was the most difficult and complex flume replacement project the El Dorado Irrigation District had undertaken to date, due to the scope of the project, access constraints, and site conditions. The flume had been identified as high-priority due to an adjacent landslide, the unstable hand-stacked rock foundation, and degraded structures.
How HCSS Software assisted with this project
ProVen’s project management team was able to pick up the estimate prepared using HeavyBid and quickly comprehend the challenges presented by this project and how the work activities were detailed. The completeness of the bid allowed for critical submittals to be identified and the procurement to be expedited. When the shutdown of the water system went into effect, crews had already done the preparatory work.
