This is a Specifications document for the City of Moorpark, California, detailing requirements for the trenchless rehabilitation of a 1,200 linear feet storm drain pipe system. The project involves the in-place lining of existing 60-inch corrugated metal pipe (CMP) along Pembridge Street, extending from approximately 80 feet north of Pederson Road to Whitman Court near Moorpark Road. Contractors may utilize either Spin-cast Geopolymer Mortar Lining or Cured-In-Place Pipe (CIPP) lining technology to restore structural capacity and extend service life without open-trench excavation. Work scope includes construction of a new utility maintenance hole, removal and replacement of existing access structures, adjustment of manhole frames and covers, temporary stormwater management or bypass pumping as necessary, traffic control, surface restoration, and project closeout. The specifications reference Drawing Number 22-11A (Sheets 1-6) and establish the technical standards and performance requirements that contractors must meet throughout project execution.

The specifications establish detailed technical requirements for materials, installation methods, testing procedures, and quality assurance standards applicable to the selected rehabilitation technology. Contractors must comply with industry standards and local requirements for trenchless pipe rehabilitation, including specifications for geopolymer mortar properties, CIPP resin formulations, cure times, and structural performance verification. The document outlines inspection and testing protocols, surface restoration standards, and temporary protection measures during construction. All labor, materials, tools, equipment, and incidentals necessary for project completion are the contractor's responsibility, with work execution designed to minimize construction duration, surface disruption, and utility impacts to the surrounding residential neighborhood.
