NDST Traffic Signal Rebuild Designs

The City of Centennial, Colorado is seeking bids for the NDST Traffic Signal Rebuild Designs project, a comprehensive infrastructure upgrade targeting four specific intersections: Dry Creek & Monaco, Dry Creek & Quebec, Dry Creek & Willow Way, and Easter & Peoria. This procurement involves fully reconstructing existing pole and mastarm type traffic signals, which requires furnishing all necessary labor, equipment, and materials. The project, identified with construction code 20240153, demands contractors to install new signal heads, poles, pedestrian push buttons, controllers, and associated electrical systems while adhering to City of Centennial and Colorado Department of Transportation standards. Bids are due on October 1, 2025, and must be submitted electronically through the Rocky Mountain E-Purchasing System, with bidders required to provide a 10% bid bond. The contract duration is set at 365 calendar days from the Notice to Proceed, with an anticipated start date shortly after contract award. Evaluation criteria will focus on bidders' qualifications, technical capabilities, compliance with specifications, and overall value to the City.

The procurement does not specify explicit set-aside designations, but it does mandate that contractors employ at least 80% Colorado labor. Contractors must demonstrate financial stability, past performance, and technical expertise in traffic signal infrastructure projects. While specific funding sources are not detailed, the project includes force account items totaling $130,000, with $100,000 allocated for minor contract revisions and $30,000 for electrical services installation. Contractors will need to coordinate with multiple utility companies including Xcel Energy, CenturyLink, Comcast, and various water and sanitation districts. The technical specifications require specific equipment such as an Econolite Cobalt traffic signal controller, a Model 350i ATC Cabinet, and a UPS system with 2000 Volt-Amp capacity. Performance and payment bonds will be required, along with maintaining specific insurance coverages. Although a precise total project budget is not specified, the comprehensive technical requirements and multiple intersection upgrades suggest a significant infrastructure investment for Arapahoe County and the City of Centennial.
