About this file

Written by GovTribe AI · Apr 10, 2025

The document is a set of construction drawings for the Arapahoe Basin Tank Installation project, prepared for the Colorado Department of Transportation (CDOT). The drawings, issued for bid on 4/8/2025 with job number 17133, provide technical specifications for installing one 2,500-gallon sand-oil separator tank and one 5,000-gallon holding tank at the CDOT A-Basin facility located at 28214 Highway 6 in Dillon, Colorado. The project involves utilizing existing floor drain piping to connect the new tanks beneath the exterior asphalt surface and filling the existing 2,500-gallon tank containment with concrete.

The construction drawings (labeled C1-C4) include detailed notes instructing contractors to verify existing site levels and dimensions prior to commencing work. Contractors are advised to carefully review all project drawings, construction notes, and specifications, and to immediately report any discrepancies. The drawings appear to be technical schematics providing precise installation guidelines for the tank replacement and modification project at the CDOT facility.
