20250407 Schedule of Values - Addendum No. 3.xlsx

This document is a Schedule of Values Addendum for the Chaffee County Phase 2 Cell 7 Construction Project located in Salida, Colorado. The project involves constructing a new 6.6-acre municipal solid waste disposal cell for Chaffee County, with geosynthetic liner installation as the primary scope. The schedule of values details six primary line items including mobilization/demobilization, geosynthetic clay liner (288,080 SF), geomembrane (288,080 SF), geotextile (156,047 SF), anchor trench and liner terminations/connections, and turf reinforcement mat (2,650 SF). The project requires installing a liner system with a geosynthetic clay liner and high-density polyethylene geomembrane, which will connect to existing Phase 2 Cell 6 and Phase 1 Cell 2.

The contract opportunity involves Chaffee County soliciting bids for a contractor to purchase, deliver, and install geosynthetics for the liner system, with all sitework and earthwork to be performed by Chaffee County Landfill and Road & Bridge Department personnel. While the schedule of values shows a total estimated contract price, no specific dollar amounts are currently populated in the unit price or total price columns. The project's unique characteristics include its location upgradient of Phase 2 Cell 6, which eliminates the need for a leachate sump, and the requirement for the contractor to supply geotextile that will be installed by the county over a sand drainage layer in the cell's base area.
