Batch 3 - Span Wire to Mast Arm Traffic Signal Rebuild Designs

The City of Centennial, Colorado is seeking bids for Project No. 25-09-04, a comprehensive traffic signal infrastructure upgrade known as the Batch 3 - Span Wire to Mast Arm Traffic Signal Rebuilds. The procurement involves reconstructing existing span wire traffic signals with new pole and mast arm type signals at three specific intersections: Arapahoe & Franklin, Dry Creek & Franklin, and Dry Creek & Clarkson. Deliverables include complete traffic signal infrastructure replacement, including electrical work, signage, pedestrian signals, CCTV cameras, fiber optic cable installation, and associated communication systems. The project requires contractors to self-perform at least 70% of the work and employ a minimum of 80% Colorado labor with preference for Colorado-produced materials. Bids are due electronically through the Rocky Mountain E-Purchasing System by 2:00 p.m. local time on October 2, 2025, with a contract time estimated at 365 calendar days from the Notice to Proceed. Contractors must provide a 10% bid security and comprehensive insurance coverage, including commercial general liability, workers' compensation, and automotive liability.

The solicitation does not explicitly indicate specific set-aside designations for disadvantaged enterprises, though it does emphasize local labor and material preferences. The project will require coordination with multiple utility and municipal entities, including Denver Water, Xcel Energy, CenturyLink, and the Southeast Metro Stormwater Authority, particularly for the Dry Creek & Clarkson intersection located in a floodplain. While no incumbent vendors are mentioned, the project involves replacing existing infrastructure with modern mast arm traffic signals, with mast arm lengths ranging from 30 to 55 feet. The geotechnical report indicates the project area consists of predominantly clayey soils, and foundation recommendations follow the City of Centennial's Traffic Signals design standards. Though a specific total project budget is not disclosed, the comprehensive nature of the work, which includes multiple intersections and sophisticated electrical and communication infrastructure upgrades, suggests a significant investment in municipal transportation infrastructure.
