About this file
This is an Addendum 4 to the 100% Complete Construction Documents for the National Park Service's Replace Wastewater Plant South Rim Village project (GRCA-257282). The addendum addresses bidder questions received on August 27, 2026, regarding the 100% Final Construction Documents dated June 2025.
The addendum documents minor revisions to two drawings resulting from bidder inquiries. Sheet 391 (Drawing 87S1030), the Compost Facility Structural Foundation Plan and Detail, was updated to add Detail 2 for drilled pier reinforcement specifications. Sheet 361 (Drawing 80D3002), the Digester Facility Mechanical Sections, was revised to correct detail numbering and valve sizing. No revisions to standard details or specifications were required. The revised documents are presented in markup format with additions shown in red, deletions in green, and notes in blue. Upon project award, these revisions will be incorporated into the conformed contract documents. The construction documents were prepared by Jacobs Government Services Company (Greenwood Village, CO) under Contract No. 140P2023D0006, Task Order No. 140P2023F0235.
