Summary
The Val Vista water transmission main includes pipe sizes ranging from 72 inches to 108 inches in diameter. A scoping analysis was completed on the Val Vista transmission main in 2016, which determined that the first four sections of the transmission main require slip-lining. Additional sections will be rehabilitated in future construction phases.
Achen-Gardner Construction, LLC, will assume the risk of delivering the project through a GMP contract. The CMAR will be responsible for construction means and methods, participation with the City in a process to set goals for local and Small Business Enterprise (SBE) participation, and implementation of the local and SBE processes. The SBE goal will be established prior to construction. The CMAR will also be required to solicit bids from prequalified subcontractors and to perform the work using the City’s subcontractor selection process. The CMAR may also compete to self-perform limited amounts of work.
