About this file
This Schedule of Items details the Park Lake Dam Rehabilitation project for the Helena-Lewis and Clark National Forest, with contract number 1240LU26Q0013. The project encompasses comprehensive dam reconstruction activities including preconstruction tasks, clearing and grubbing, deconstruction, reconstruction, seismic foundation improvements, hydraulic seepage control, road reconstruction, and reclamation. Key quantities include 22,200 cubic yards of dam excavation, 24,000 cubic yards of embankment fill, 20,300 square yards of clearing and grubbing, and multiple specialized activities such as compaction grouting, drain pipe installation, riprap placement, and instrumentation. The scope involves detailed engineering work with specific requirements for materials like filter layers, concrete sand, and aggregate, along with infrastructure elements such as fencing, gates, and road improvements.
