RFQ: On-Call Professional Engineering for Community Network Bikeway Planning Services

The City and County of Denver Department of Public Works (DPW) is rapidly implementing multimodal projects around the concept of completing an entire network within smaller areas of the City, a process the planning team has called the “Community Network” approach. This approach will provide a combination of multimodal projects (pedestrian, bike, transit, vision zero). The intent of network implementation is to meet our modal goals of 30% mode shift and reduction to 50% SOV. This contract focuses primarily upon providing consulting services for multimodal projects within three Community Networks that require planning services. It is the intent of DPW to award three contracts through this RFQ, one contract for each Community Network. Consultants are encouraged to rank each area to indicate which Community Network is best suited for the team. The attached Community Network Bikeway Maps display bikeway projects within the Community Networks that require planning services, as well as those that will go directly to the Design Phase. Consultants should note that a large proportion of projects to be planned include Neighborhood Bikeways. However, in this planning process, improvements for all multimodal transportation should be identified within each community. Planning services will include alternatives analysis, data collection and analysis, concept development, implementing a public participation process, conceptual cost development, risk assessment and working with neighborhood and City and County of Denver (CCD) stakeholders towards developing a multimodal community network concept for design development.
