About this file
This is a Schedule of Items for federal contract 1240LU26Q0013, updated February 2, 2026, for the Park Lake Dam Rehabilitation project located in the Helena-Lewis and Clark National Forest. The schedule outlines a comprehensive base bid and one optional work package with detailed line items, quantities, units of measure, and provisions for unit pricing and cost calculations.
The base bid encompasses preconstruction activities (mobilization, access road improvements, construction staking, and temporary traffic control); clearing and grubbing (20,300 square yards downstream of dam); deconstruction including dam excavation (22,200 cubic yards in-situ), temporary stockpiling (24,000 cubic yards), and borrow material procurement (3,750 cubic yards); reconstruction featuring embankment fill (24,000 cubic yards compacted), soil mixing and disking (30,260 cubic yards), Class 2 riprap placement for dam and saddle dike (770 and 5,860 cubic yards respectively), multiple filter and bedding layers, drainage pipe installation (270 linear feet perforated and 240 linear feet solid), and a 24-inch riser inlet. The base bid also includes seismic foundation improvements with primary and secondary borings and compaction grouting (132 and 30 units), hydraulic seepage control barrier work with shallow, mid-level, and deep borings (179, 62, and 33 units), road reconstruction with 425 cubic yards of surface aggregate and gate installations, reclamation work including vegetation transplanting, and instrumentation additions (14 piezometers and one early warning system). A saddle dike section requires 6,260 cubic yards of soil borrow and 5,641 cubic yards of embankment fill. Optional work (Option 001) includes roadway reconditioning for 16.8 miles, involving blade work on a 5.6-mile stretch repeated three times. The vendor must provide name, representative, SAM UEI number, phone, and email upon submission.
