Nederman Exhaust System

The City of Aurora is procuring a comprehensive diesel exhaust removal system replacement for its Public Safety Training Center (CAPSTC), located at 25950 East Quincy Avenue in Aurora, Colorado. The project involves completely removing the existing Plymovent diesel exhaust removal system from three truck bays and installing a new Nederman diesel exhaust removal system that will run the entire length of the 2nd and 3rd truck bays and a portion of the 1st bay. Key deliverables include removing existing track, hose drop, ductwork, and exhaust fan, and installing new ductwork, a new exhaust fan, and revised electrical connections. The procurement requires a contractor with expertise in mechanical and electrical systems, specifically diesel exhaust management infrastructure. The bid submission deadline is August 11, 2025, with a mandatory pre-bid conference scheduled for July 16, 2025. A third-party commissioning process with NORESCO will ensure the system is correctly installed and meets design performance standards. Project documents indicate a phased development approach, with construction issue documents dated May 16, 2025, and previous milestones including 65% construction documents on December 10, 2024.

The contract includes specific set-aside provisions, including a Small Business Enterprise (SBE) program that requires contractors to make good faith efforts to award at least 10% of subcontracting dollars to SBEs for construction contracts over $250,000. Additionally, the project mandates that at least 80% of labor must be from Colorado residents, emphasizing local workforce engagement. Contractors must provide a 5% bid bond, performance and payment bonds, and maintain specific insurance coverages. The estimated project cost ranges from $150,000 to $175,000, with liquidated damages of $1,000 per day for failure to complete work on time. The project will require compliance with Colorado labor laws, equal opportunity employment provisions, and potential federal funding guidelines. Contractors must be prepared to provide comprehensive documentation, including record drawings, operation and maintenance manuals, and ensure all systems are fully functional and compliant with city codes and specifications. The project is set to be completed by December 31, 2025, with strict adherence to the detailed technical specifications outlined in the project manual.
