About this file
The document is a Centrifugally Cast Concrete Pipe (CCCP) Specification for the City of Sandy Springs Mountain Creek Culvert Project, prepared by Pond & Company in March 2025. The specification outlines detailed requirements for installing a concrete pipe liner within existing storm sewer pipe structures, with the goal of creating a continuous structural concrete pipe inside the current infrastructure. The project involves installing CCCP liners that will provide an equal or greater opening area compared to the proposed plans, with measurement and payment calculated by linear foot of installed liner.
The specification includes comprehensive technical requirements for materials, including specific performance standards for compressive strength, flexural strength, tensile strength, bond strength, and abrasion resistance. The CCCP liner geopolymer mortar must be composed of at least 70% Pozzolanic material and verified through third-party X-ray Fluorescence testing. The contract includes provisions for installation conditions, such as temperature restrictions (between 45°F and 100°F), surface preparation, drainage maintenance, and use of a curing compound. Payment terms stipulate that no compensation will be provided for liners that cannot be successfully installed due to existing structure conditions, and the contractor is responsible for all preparatory and remediation work.
