Not all of the specification divisions are required for every construction project. Divisions that are not required for a construction project are normally omitted. Sections under one of these general categories generally begin with GENERAL REQUIREMENTS for that category and continue with the SPECIFIC REQUIREMENTS. An example of a section of Division 15 (MECHANICAL) follows.
In studying the guide specifications for plumbing which follow, study the drawing shown in figure 1-16, keeping in mind that these specifications are for this project and are listed as samples.
Section 15. 1a- Plumbing
15. 1a-01. GENERAL REQUIREMENTS. The work consists of a complete plumbing system, including the sanitary soil, waste, and vent piping; cold- and hot- water supply piping, water meter (if required), plumbing fixtures, hot-water heater, and other appurtenances. The system must be inspected, tested, and approved by local governing plumbing codes before burying, concealing, or covering the various piping systems. Each system must be complete and ready for operation except as specified or indicated otherwise.
15. 1a-02. SANITARY SEWER, BELOW-GROUND level, must be of extra-heavy cast-iron soil piping and fittings of the bell-and-spigot type, extending 3 to 5 feet beyond the foundation wall and graded not less than 1/8 inch per foot. The joint will be made from a good grade of twisted oakum uniformly and well-tamped into the joint and with a l-inch depth of hot poured lead, made in one pouring, and caulked tight. All horizontal soil connections to the system must be accomplished by Y-fittings or combination Y and 1/8 bends. All changes in direction greater than a 1/8 bend must be of the long sweep pattern.
