Report
Summary
As part of the Transmission Main Inspection and Assessment Program, it has been determined there is a need to rehabilitate one mile of 60-inch Pre-stressed Concrete Cylinder Pipe (PCCP) transmission main extending south along 36th Street from Roeser Road to Vineyard Road. A distressed, single-pipe section 20 feet long on Baseline Road will also be evaluated for rehabilitation. This project will evaluate relocation versus rehabilitation alternatives. Included in this analysis will be evaluation of applicable pipe rehabilitation technologies and alternative routes for relocation of the main. Project design will be dictated by the chosen improvement alternative.
Achen-Gardner Construction, LLC will begin in an agency support role for Design Phase Services and then hold the construction contract with the City for construction of the project.
Services during the CMAR Design Phase include: providing detailed cost estimating and identification of marketplace conditions; planning and scheduling project/construction phases to minimize interruption to City operations; evaluating alternate systems; providing constructability studies; advising on potential efficiencies in project delivery; performing and initiating long-lead studies and procurements; assisting in permitting processes; and participating in the Small Business Enterprise (SBE) process to establish the SBE goal prior to construction.
