The City and County of Denver is issuing a competitive Invitation for Bid (IFB) No. 202578378 for Annual Water Quality Infrastructure Improvements at Denver International Airport (DEN), targeting two distinct project sites involving water quality and detention infrastructure construction. The procurement seeks a qualified contractor to construct regional water quality and detention ponds at 7491 N Gun Club Road and 24735 E 75th Avenue, which will involve comprehensive civil engineering work including earthwork, grading, storm drainage line construction, concrete work, and erosion control measures. The first site will create a regional water quality pond serving a 140-acre tributary area and eliminate three existing water quality ponds, while the second site will construct a consolidated water quality pond for the WorldPort development and decommission two existing ponds. Mandatory contractor qualifications include being prequalified in category 1A: Heavy Civil at or above the $9,000,000 monetary level. Bids are due by May 16, 2025, at 2:00 pm Denver local time, with anticipated construction start in September 2025 and a projected 150-calendar-day project duration. The procurement is driven by DEN's annual erosion control Capital Improvement Plan and compliance requirements under the Denver Revised Municipal Code.
The contract includes a 16% Minority and Women-Owned Business Enterprise (MWBE) participation requirement, creating opportunities for disadvantaged business enterprises. Contractors must submit a bid guarantee of 5% of the total contract amount and provide specific insurance coverage, including commercial general liability, business automobile liability, workers' compensation, and contractors pollution liability insurance. While the exact contract value is not explicitly stated, the comprehensive technical specifications and project scope suggest a significant infrastructure investment. The project will be funded through the airport's Capital Improvement Plan and includes provisions for liquidated damages of $2,000 per calendar day for failing to achieve substantial completion within the specified timeframe. Contractors must comply with prevailing wage regulations, equal employment opportunity provisions, and utilize the Colorado Department of Transportation (CDOT) 2023 Standard Specifications as a baseline for construction methodologies. The technical approach emphasizes water quality management, erosion control, and environmental considerations, with detailed instructions for soil preparation, seeding methods, and infrastructure construction techniques.
Opportunity text
This request is for a competitive Invitation for Bid (IFB) procurement to select a qualified contractor to provide Annual Water Quality Infrastructure Improvements at Denver International Airport (DEN). DEN seeks to construct storm drainage and water quality/detention infrastructure at two distinct project sites under the same project. This procurement is driven by the annual erosion control Capital Improvement Plan (CIP) program that requires DEN to make improvements to stormwater infrastructure as a compliance obligation under the Denver Revised Municipal Code Sec 56-112. The first project site, located at 7491 N Gun Club Road, proposes the construction of a regional water quality and detention pond southwest of the 75th Avenue and Gun Club Road intersection, and east of Second Creek. The proposed pond provides regional water quality and detention for a 140-acre tributary area and will eliminate the need for three existing water quality ponds that are tributary to the site. The construction scope includes earthwork and grading, construction of storm drainage lines and improvements to an open drainage channel, construction of the water quality pond and associated concrete work, and erosion and sediment control measures. The work at this site will also include the demolition and decommissioning of three existing water quality ponds in the vicinity. The second project site, located at 24735 E 75th Avenue, proposes the construction of a consolidated water quality and detention pond that north of the WorldPort #12 Building. Stormwater runoff from the WorldPort development currently drains to two existing water quality ponds, which will be decommissioned as part of the work. The construction scope includes earthwork and grading, construction of storm drainage lines, removal and replacement of asphalt pavement and curb and gutter, construction of the new water quality pond and associated concrete work, and erosion and sediment control measures. The demolition and decommissioning of two existing water quality ponds is included in the scope as well.
