RFP-SK-2016-12 - WOLFENSBERGER RD CULVERT REPLACEMENT AT OMNI TRIBUTARY

Summary of Specifications:
Castle Rock is seeking a Consultant Team to provide design engineering services for a culvert replacement capital improvement project under Wolfensberger Road at the Omni Tributary drainageway. The capacity, and condition, of the existing culverts is currently insufficient to convey the 100-year storm event flows. Storm flows are expected to periodically overtop Wolfensberger Road disrupting traffic and potentially impacting adjacent proposed development. The existing Wolfensberger Road culvert system at the Omni Tributary includes two 48-inch diameter corrugated metal pipes (CMPs). The existing Omni Tributary channel in this area has a sandy bottom which varies in width, with bank erosion occurring intermittently along its length, and with upland grasses, shrubs and pine trees located outside the channel. Expertise for this project is solicited in culvert design, floodplain management, transportation design, traffic control, water control, surveying and environmental permitting.
