TRI-lakes project weed control

The U.S. Army Corps of Engineers, Omaha District, is soliciting proposals for noxious weed control and vegetation management services across three dam locations in Colorado: Chatfield Dam (435.1 acres), Cherry Creek Dam (252.7 acres), and Bear Creek Dam (314.2 acres), totaling approximately 1,002 acres. Contractors must possess a Colorado commercial applicator license and demonstrate the capability to perform large-acreage spraying operations of 750 or more acres, utilizing only ground-based equipment such as 4-wheel drive vehicles, ATVs, or backpack units. Work must achieve 100% control of total vegetation in designated areas and 85% control of noxious weeds in other areas, with contractors responsible for determining application schedules based on weed growth conditions. Evaluation will be based on past performance (demonstrating successful completion of comparable pesticide application projects within the past three years), technical approach (including recommendations of appropriate chemicals and application rates), support equipment and facilities capabilities, and price, with past performance, technical approach, and equipment capability weighted as significantly more important than price. The proposal due date is March 27, 2026, at 2:00 PM, with offerors required to submit questions in writing no later than seven calendar days prior to the due date; proposals must not exceed 25 pages and be submitted electronically to Contracting Officer Tina Keimig at tina.l.keimig@usace.army.mil.

This solicitation is designated as a 100% total small business set-aside, with the previous contract holder identified as Horizon Vegetation Management Inc. The total award amount is $9,500,000.00, with pricing structured on a per-acre basis across the three dam locations. The base contract period runs from April 1, 2026, through March 31, 2027, with two optional one-year extension periods extending through March 31, 2029, on a firm fixed-price basis. Contractors must maintain minimum insurance coverage including $100,000 workers' compensation, $1,000,000 general liability, and $200,000 automobile liability, and all contract personnel must complete security training within 30 days of award. Work will be performed at three Colorado dam locations in the greater Denver metropolitan area, with inspection and acceptance occurring at both origin and destination, and final oversight conducted by the Contracting Officer's Representative at the Tri-Lakes Project Office in Littleton, Colorado.
