Contractors have the information necessary so that they may properly install all necessary connections and equipment. Identify all work items needing access (dampers and similar equipment) that are concealed above hung ceilings by permanent color-coded pins/tabs in the ceiling directly below the item.

D. At the conclusion of each day's work, clean up and stockpile on site all waste, debris, and trash which may have accumulated during the day because of work by the contractor and of his presence on the job.

3.3 UNDERGROUND PIPING INSTALLATION

F. Pipe Joints: Pipe joints must conform to NFPA 13, except as modified herein. Not more than four threads may show after the joint is made up.

Welded joints will be permitted, only if welding operations are performed as required by <NFPA 13 at the Contractor's fabrication shop, not at the project construction site. Flanged joints must be provided as required by NFPA 13. Grooved pipe and fittings must be prepared in accordance with the manufacturer's latest published specification according to pipe material, wall thickness, and size. Grooved couplings, fittings, and grooving tools must be products of the same manufacturer. The diameter of grooves made in the field must be measured using a "go/no-go" gauge, vernier or dial caliper, narrow-land micrometer, or other method specifically approved by the coupling manufacturer for the intended application. Groove width and dimension of groove from end of pipe must be measured and recorded for each change in grooving tool setup to verify compliance with coupling manufacturer's tolerances. Grooved joints must not be used in concealed locations, such as behind solid walls or ceilings, unless an access panel is shown on the Contract Drawings for servicing or adjusting the joint.

G. Reducers: Reduction in pipe sizes must be made with one-piece tapered reducing fittings. When standard fittings of the required size are not manufactured, single bushings of the face or hex type will be permitted. Where used, face bushings must be installed with the outer face flush with the face of the fitting opening being reduced.

Bushings must not be used in elbow fittings, in more than one outlet of a tee, in more than two outlets of a cross, or where the reduction in size is less than 1/2-inch.

H. Pipe Penetrations: Cutting structural members for passage of pipes or for pipe-hanger fastenings must not be permitted. Pipes that must penetrate concrete or masonry walls or concrete floors must be core-drilled or have sleeves installed during wall or floor construction.

3.10 SYSTEM ACCEPTANCE

A. Following acceptance of the system as-built drawings and Operating and

Maintenance (O&M) Instructions must be delivered to the COR for review and acceptance. These drawings must be submitted within two weeks after the final acceptance test of the system. At least one set of as-built

(marked-up) drawings must be provided at the time of, or prior to, the final acceptance test.

3.11 INSTRUCTION AND TRAINING

A. Conduct a training course for the responding fire department and operating and maintenance personnel as designated by the COR for not less than two hours on a date set by the COR. Instruction should include operation and maintenance of the system. Training must start after the system is functionally complete and after the final testing.

The on-site training must cover all the items contained in the approved

Operating and Maintenance Instructions.
