Truckee Tahoe Airport – – 2014 PMMP Update 2014 PMMP Update Truckee Tahoe Airport Construction Cost Changes and Lessons Learned: Existing Subgrades in Hangar Areas were found to be variable, soft, unstable, and required overexcavation and stabilization. Hangar Taxilanes A-H need to be reconstructed instead of just removing and replacing the existing AC due to unstable subgrades. Existing subgrade soils in Apron and Runway areas are much more difficult to excavate than originally anticipated due to the amount of cobbles present. Unit prices were increased for excavation in construction estimates to account for difficulty of excavation. Added Reclaimite Seal Coat for some pavements to help surface condition of the pavement. Updated all estimates to 2014 prices. Reinard W . Brandley CONSULTI NG AI RPORT ENGI NEER
