Title
Award of Contract for Tower/Pena Ramp Construction Management Services
Body
Summary and Background Information: Commerce City and the City and County of Denver have executed an IGA for construction and cost sharing of the Tower-Pena Ramp project. The project will be managed by Commerce City with the construction being performed in the City and County of Denver and DEN right of way. Commerce City and the E-470 Public Highway Authority also have an executed IGA for reimbursement to the City of a portion of the ramp construction costs.
Scope of Work
The Tower-Pena Ramp project will construct a new westbound on ramp at the interchange of Tower Road with Peña Boulevard. The westbound off ramp and the intersection of the westbound ramps will be relocated further south than the current intersection resulting in a “tight diamond” configuration with Peña Boulevard. Therefore, a significant portion of the existing westbound off ramp will need to be re-constructed in a new alignment and the existing traffic signal for the westbound ramps will be replaced. The project will also widen Tower Road from two lanes to four lanes with curb and gutter and a native grass median between 80th Avenue to the eastbound ramps of Peña Boulevard. The Tower Road work will include sidewalks, street lighting, storm water detention and water quality ponds and provisions for future landscaping.
The CM services will span the construction timeframe. Services include, but are not limited to, Construction Management, Inspection, Quality Assurance and Coordination, Construction Contract Management and Mobilization/Demobilization Support.
