20250407 CCLF Ph2 C7 Addendum No. 3.pdf

This document is Addendum No. 3 for the Phase 2 Cell 7 Construction project at the Chaffee County Landfill in Salida, Colorado, issued by Sanborn, Head & Associates, Inc. on April 7, 2025. The addendum addresses a correction in the Schedule of Values (Bid Form) previously provided in Addendum No. 2, specifically noting that the subtotal equation did not initially include mobilization/demobilization costs. The addendum requires bidders to acknowledge receipt of this update in their proposal and includes a corrected Excel file with the revised schedule.

The addendum does not provide additional pricing details or funding information beyond the procedural correction to the bid form. The document is addressed to bidders and copies are distributed to Chaffee County representatives Don Reimer, Beth Helmke, and Shannon Wilcox, as well as Sanborn Head internal contacts Timothy Reed and Marcel Kozlowski. The file is associated with the larger Landfill Disposal Cell Construction project, which involves constructing a 6.6-acre disposal cell with specific geosynthetic liner system requirements, including a geosynthetic clay liner and high-density polyethylene geomembrane.
