GLRR 2015-109M14 REBID Bid Sheet 2.5.2016.pdf

This is a bid sheet for a rebid contract opportunity (GLRR 2015-109M14) dated February 5, 2016, for tunnel excavation and support work. The project encompasses two main components: the Everett Tunnel and a Cross Passageway Tunnel (add/alternate). The Everett Tunnel scope includes 15 line items covering mobilization, furnishing and installing 10 steel sets, installing 75 spiles, applying shotcrete across 200 square feet, drilling and injecting pre- and post-excavation grout (chemical and cement), excavating and hauling 20 cubic yards of rubble material, providing 100 hours of QC inspection services, and installing permanent lighting. The Cross Passageway Tunnel component (items 16-29) involves excavating an 8-foot by 8-foot tunnel for 250 linear feet, furnishing and installing 4 steel sets, 8 rock bolts, welded wire fabric, mine straps, and split sets, along with shotcrete application, blasting zone management, and permanent lighting installation.

The bid sheet establishes unit price line items for all work components, with variations in quantities permitted for certain items including steel sets, spiles, grout holes, grout, wood lagging, wood cladding, and rubble excavation, which may vary up to plus or minus 50 percent at the contractor's unit price. The sheet specifies that "furnish only" quantities will be paid in full regardless of installation, while "install only" quantities will be compensated only for work actually completed. The extent of the rubble pile is noted as estimated, acknowledging that actual quantities may differ from the bid sheet projections. This structure allows for cost flexibility while maintaining a defined pricing framework for competitive bidding.
