Moorpark Road Storm Drain Pipe (CMP) Lining and Repair at Pembridge Street.pdf

This is a project specification document for the Moorpark Road Storm Drain Pipe (CMP) Lining and Repair project in California. The project involves the trenchless rehabilitation of approximately 1,200 linear feet of existing 60-inch corrugated metal storm drain pipe located along Pembridge Street, beginning approximately 80 feet north of Pederson Road and ending at Whitman Court, roughly 300 feet east of Moorpark Road. The rehabilitation will be executed using either Spin-cast Geopolymer Mortar Lining or Cured-In-Place Pipe (CIPP) lining methodologies to restore structural capacity and extend the service life of the stormwater facility. Additional work scope includes constructing a new utility maintenance hole, removing and replacing existing access structures, adjusting manhole frames and covers, implementing temporary stormwater management or bypass pumping systems, providing traffic control, performing surface restoration, and completing project closeout activities. The project is governed by Drawing Number 22-11A (Sheets 1-6) and associated specifications and contract documents.

The project utilizes trenchless rehabilitation techniques specifically to minimize construction duration, reduce overall costs, limit surface disruption, and mitigate utility impacts to the surrounding neighborhood. Contractors must furnish all labor, materials, tools, equipment, and incidentals required to complete the work as specified in the contract documents. The trenchless approach eliminates the need for open-trench excavation, representing a modern infrastructure rehabilitation strategy that balances project completion efficiency with community considerations.
