About this file
This is a Specification Section for Water Distribution Systems (Section 221100) for the Red Canyon Paving project under the USDA Forest Service, R-4.
The project requires furnishing and installing potable water distribution pipe and fittings. Materials specified include galvanized steel pipe meeting ASTM A53 Schedule 40 with threaded ends per ASME B1.20.1, and threaded fittings per ASTM A 338. All materials must be new and unused with proper pressure ratings and classes as shown on project drawings. All work must comply with applicable Federal, State, and Local codes, and piping materials must bear markings from a specified testing agency. Delivery shall include factory-applied end caps maintained through shipping and storage; stored piping must be protected from moisture, dirt, and direct sunlight with proper support to prevent sagging. Pipe sleeves must be installed before aggregate or asphalt placement and extended a minimum of three feet beyond the edge of pavement where waterlines cross road paving. Sleeves require end seals or threaded caps to provide a positive seal against hydrostatic head and prevent soil infiltration, with one 2x4 installed at each end and partially buried for future location. Payment is based on linear feet of pipe sleeve including trench excavation, backfill, and 2x4 placement. Utility interruptions require prior written permission from the Contracting Officer.
