EXECUTION

3.1

INSTALLATION

Install materials and equipment as indicated and in accordance with

manufacturer's recommendations.

3.1.1

Excavation and Backfilling

Section 02300 EARTHWORK.

3.1.2

Corrosion Protection

Provide corrosion protection for buried steel [and corrosion resistant

steel] piping in accordance with Section 09974 PROTECTION OF BURIED STEEL

PIPING AND STEEL BULKHEAD TIE RODS.

3.1.3

Piping

Provide Non-Destructive Examination (NDE) report for welding of piping.

Unless specifically stated to the contrary, fabrication, assembly, welding,

and brazing shall conform to ASME B31.1 for all piping of the air system.

Piping shall follow the general arrangement shown. Cut piping accurately

to measurements established for the work. Work piping into place without

springing or forcing, except where cold-springing is specified. Piping and

equipment within buildings shall be entirely out of the way of lighting

fixtures and doors, windows, and other openings. Locate overhead piping in

buildings in the most inconspicuous positions. Do not bury or conceal

piping until it has been inspected, tested, and approved. Where pipe

passes through building structure, pipe joints shall not be concealed, but

shall be located where they may be readily inspected and building structure

shall not be weakened. Avoid interference with other piping, conduit, or

equipment. Except where specifically shown otherwise, vertical piping

shall run plumb and straight and parallel to walls. Piping connected to

equipment shall be installed to provide flexibility for vibration.

Adequately support and anchor piping so that strain from weight of piping

is not imposed on the equipment.
