Water Main Design & Utility Coordination

JR Engineering designed approximately 2,000 linear feet of new 24-inch PVC water main as part of the City of Greeley’s O Street and 59th Avenue Intersection Improvements project. The waterline was incorporated into the larger design of a new roundabout and associated roadway improvements, allowing the City to construct the new water infrastructure concurrently with the intersection project. The overall project was delivered as a Local Agency project requiring coordination and review with CDOT Region 4.

​

The water main extended along O Street and 59th Avenue and required coordination with the roadway design and existing and proposed infrastructure within the project corridor. The broader intersection project included utility locating/SUE and utility adjustments as part of the design process, as well as development of plans through conceptual, 30%, 75%, 95%, and final construction documents.

Railroad Crossing & Agency Coordination

A key component of the waterline design was crossing the Great Western Railroad immediately south of O Street. JR Engineering coordinated with OmniTRAX for a bored installation beneath the existing railroad tracks while also coordinating with the City of Greeley, CDOT, irrigation ditch owners, and other project stakeholders. The RFP specifically required coordination and agreements associated with improvements at the Great Western Railroad crossing, making railroad coordination an integral component of the overall corridor design.

​

JR Engineering prepared plans, specifications, and cost estimates for the improvements and coordinated the waterline design with the overall intersection project. The resulting design provided approximately 2,000 linear feet of new 24-inch City water main while addressing the constraints of the roadway, railroad, existing utilities, and surrounding infrastructure.
