NOAA Anderson Ditch Project

The National Institute of Standards and Technology (NIST), under the Department of Commerce, is seeking construction services for the NOAA Anderson Ditch Project, which involves maintenance and reconfiguration of the Anderson Ditch easement to ensure a water carrying capacity of 25 cubic feet per second behind the NOAA Skaggs Building on the NIST Boulder Campus. The work includes removing vegetation, relocating boulders and memorial structures, investigating drainage, and ensuring proper ditch access and water flow, with the contractor responsible for completing all work according to the scope without requiring design or engineering services from the government. The solicitation includes a base contract for Phase 1 maintenance and an option for Phase 2 maintenance, with an estimated Notice to Proceed date of August 19, 2025. Proposals will be evaluated based on technical approach, schedule, past performance, and price, with non-price factors being more important than price considerations. The original solicitation was published on July 11, 2025, with three amendments issued to address contractor questions and update wage determinations, and all proposals are due by July 31, 2025, no later than 2:00 PM Mountain Time.

This opportunity is designated as a 100% Small Business Set-Aside under NAICS code 237990 (Other Heavy and Civil Engineering Construction) with a small business size standard of $45.0 million. The contract value is estimated to fall within the $250,000-$500,000 range, with a performance period of approximately six months. Multiple companies demonstrated interest by attending the site visit on June 18, 2025, including Elite Surface Infrastructure, K & M Landscaping and Design, H2 Enterprises, Western States Reclamation, Ecological Construction Services, M1 Mechanical, and Front Range Construction. All work will be performed in Boulder, Colorado 80305, specifically on the NIST Boulder Campus, and contractors must ensure that all personnel complete full badging requirements, with temporary daily badges required until permanent badging is obtained. The project requires contractors to stockpile trees and mulch outside the 12-foot easement and ensure complete removal and proper disposal of all materials by the end of the contract performance period.
