PART 3 EXECUTION

3.01 PREPARATION

A. Field Measurement: The Drawings are in general indicative of the Work, with symbols and notations for clarity. However, the Drawings are not an exact representation of all conditions involved, therefore, layout piping to suit actual field measurements.

1. No extra compensation will be made for Work due to difference between indicated and actual dimensions.

2. Submit to the Contracting Officer for approval, details of proposed departures necessitated by field conditions or other causes.

B. Interferences: Layout piping systems to compensate for structural interferences, to preserve headroom, and not to interfere with openings, passageways and equipment. Do not install piping with joints and fittings over motors, switchboards, panels, or similar electrical apparatus.

3.02 PERFORMANCE

A. Perform sprinkler piping system installation in conformance with the requirements of NFPA No. 13 as directly appropriate to the work.

B. Perform underground fire line installations in conformance with the requirements of NFPA No. 24 as directly appropriate to the work.

3.03 INSTALLATION

A. The sprinkler system piping is to be provided with sway bracing.

B. General Requirements: The schematic drawings do not necessarily indicate every piping size or alignment. Provide the required pipe sizes, fittings, adapters, etc. as required to construct complete piping systems.

1. Install piping concealed in those areas of the structures having hung ceilings and exposed in all other areas, except where indicated otherwise on the Drawings.

2. Clean piping prior to installation and following installation to prepare for painting. Keep open ends of piping and pipe attachment openings on equipment capped or plugged until actual connections.

3. Construct pipe runs from full lengths of pipe using short sections only for runs of less than full pipe length. Make changes in directions of pipe runs with fittings only.

4. Cut pipe accurately to measurements established in the field and assemble in place without springing, forcing, excessive cutting or weakening of the structure.

5. Install unions and flanges in accessible locations and whether indicated or not, install union adjacent to equipment and wherever removal of equipment for repair or replacement is required.

COMMON WORK RESULTS FOR FIRE SUPPRESSION 21 05 00 - 8

6. Provide reducing fittings where reduction in pipe sizes is necessary.

Bushings will not be accepted.

7. Install gate valves as indicated on the drawings and as required by NFPA No. 13.

8. Provide tamper switches on all valves associated with the fire suppression system.

9. Pipe Supports Installation: Place and support piping runs as specified in Section 23 05 29.

C. Exposed Piping: Install exposed piping parallel or perpendicular to the lines of the building structure and to compensate for structural interferences, to preserce headroom, and not to interfere with openings, passageways and equipment.

1. Install piping a sufficient distance from other work to permit clearance of not less than one inch between the piping or insulated piping and adjacent work.

2. Install piping as close as possible to walls, overhead construction, columns, and similar to facilitate insulating work and removal of piping later.

3. Paint exposed sprinkler piping red; refer to Section 09 90 00.

D. Buried Piping: Perform earthwork involving trenching for buried pipe runs as specified in Section 31 23 33.

1. Keep trenches dewatered until pipe joints have been made and concrete bedding and blocking, if any, have hardened. Under no circumstances lay pipe in water or on subgrade containing frost.

2. Rest each section of pipe on pipe bedding for the full length of its barrel, with recesses excavated for pipe bells so joints can easily be made.

Backfill recesses with bedding material immediately following pipe joining operations.

3. Lay pipe proceeding upgrade true to line and grades given. Lay bell and spigot pipe with bell end upgrade.

4. Take up and relay pipe that is not laid true to required alignment or grade or has its joints disturbed after laying. No deviations from the required line and grade permitted, except with approval of the Contracting Officer.

5. Reaction or Thrust Backing: Install on underground lines at trees, plugs, caps and changes in direction.

a. Use 3000 lb. (Class B) concrete placed between solid undisturbed earth and fittings to be anchored. Perform concrete work as specified in Section 03 30 00.

b. Area bearing on pipe and on the ground shall be approximately nine square feet each.

COMMON WORK RESULTS FOR FIRE SUPPRESSION 21 05 00 - 9

3.04 PIPE JOINING

A. General Requirements: Exercise care when making pipe joints and make joints in accordance with the pipe material manufacturer's recommendations and the following additional requirements.

1. In each instance of pipe joining, those portions of pipes involved must be absolutely clean just prior to assembly.

2. If a joint is extremely difficult to assemble or is not completely sealed, disassemble the joint and correct the difficulty if possible. Remake the joint using new materials when necessary.

B. Ferrous Metal Piping Joints: Cut pipe ends square, deburr and ream to size of original bore.

1. Threaded: Cut threads to standard gauge depth and length and clean threads free of oil and cuttings. Provide thread lubricant as specified to aid in joint lubrication and sealing in joining operation.

2. Flanged: Face accurately, install gaskets and draw up square and tight to ensure full gasket flow and seal.

C. Ductile Cast Iron Pipe Joints:

1. Push-On Joints: Properly seat sealing gasket, evenly and sufficiently lubricate the spigot end of pipe, and fully enter joint until joint line is visible.

Make deflection, if required, only after the joint has been assembled properly.

3.05 FIELD QUALITY CONTROL

A. General Requirements: Conduct tests specified under Piping System Specifications so that each piping system installed in the Project is tested to the Contracting Officer's satisfaction.

1. Flush entire system in accordance with NFPA 13.

2. Provide tools, materials (including clean water), apparatus and instruments necessary for piping system testing.

3. Conduct tests of every kind in the presence of and to the satisfaction of the Contracting Officer.

6. Repair and Retest: When a piping system fails to meet test requirements specified herein, conform to the following:

a. Determine source or sources of leakage.

b. Repair or replace defective material, and if a result of improper workmanship, correct such.

c. Conduct additional tests to demonstrate that piping system meets specified test requirements.
