PART 3 - EXECUTION
3.1 INSTALLATION -GENERAL
A. Staking: Before installation is started, place a stake where
each sprinkler is to be located, in accordance with drawing.
Staking shall be approved by Owner Authorized
Representative before proceeding with work.
B. Excavations: Excavations are unclassified and include earth,
Dose rock, rock or any combination thereof, in wet or dry
state. Backfill benches With material removed, provided that
the earth is suitable for compaction and contains no lumps,
clods rock, debris, etc. Special backfill specifications, if
furnished take preference over this general specification.
C. Backfill: Flood or hand tamp to prevent after settling. Hand
rake trenches and adjoining area to leave grade in as good or
better condition than before installation.
D. Piping Layout Piping layout is diagrammatic. Route piping
around trees and shrubs in such a manner as to avoid damage
to plantings. Do not dig within ball of newly planted trees or
shrubs. In areas where existing trees are present, trenches
shall be adjusted on site to provide a minimum clearance of
four (4) feet between the drip line of any tree or trench. The
Contractor shall notify the Owner Authorized Representative
in
writing of a planned change in trench routing from that
shown on the drawings.
3.2 PIPE INSTALLATION
A. Sprinkler Mains: Install a four (4") inch wide minimum trench
with a minimum of eighteen (18") inches of cover.
B. Lateral Piping: Install a four (4") inch wide minimum trench
deep enough to allow for installation of sprinkler heads and
valves, but in no case, with less than twelve (12") of cover.
C. Trenching: Remove lumber, rubbish, and large rocks from
trenches. Provide firm, uniform bearing for entire length of
each pipe line to prevent uneven settlement. Wedging or
blocking of pipe shall not be permitted. Remove foreign
matter or dirt from inside of pipe before welding, and keep
piping clean by approved means during and after laying of
pipe.
3.3 PVC PIPE AND FITTING ASSEMBLY
A. Solvent: Use only solvent recommended by manufacturer to
make solvent -welded joints. Thoroughly clean pipe and
fittings of dirt, dust and moisture before applying solvent.
B. PVC to metal connection: Work metal connections first. Use
a non -hardening pipe dope such as Permatex No. 2 on
threaded PVC adapters into which pipe may be welded.
3.4 COPPER TUBING AND FITTING ASSEMBLY
SIDEWALK OR
MAINLINE RR
04QUICK COUPLER
NOT TO SCALE
A. Clean pipe and fitting thoroughly and lightly sand pipe
connections to remove residue from pipe. Attach fittings to
tubing in an approved manner using 50-50 soft solid core
solder.
3.5 POP-UP SPRAY HEADS
A. Supply pop-up spray heads in accordance with materials list
and plan. Attach sprinkler to lateral piping with a
semi- flexible polyethylene nipple not less than three 13")
inches or more than six 061 inches long.
3.6 VALVES
A. Supply valves in accordance with materials list and sized
according to drawings. Install valves in a level position in
accordance with manufacturer's specifications. See plan for
typical installation of electric valve and valve box.
3.7 WIRING

valves. No conduit will be required for OF wire unless
otherwise noted on the plan. Wire shall be tucked under the
piping.
B. A separate wire is required from the control to each electric
valve. A common neutral wire is also required from each
control to each of the valves served by each particular
control.
C. Bundle multiple wires and tape them together at ten (109
foot intervals. Install ten (10") inch expansion coils at not
more than one hundred TOO') foot intervals. Make splices
waterproof.
3.8 AUTOMATIC SPRINKLER CONTROLS
A. Supply in accordance with Irrigation Plan. Install according to
manufacturer's recommendations.
3.9 TESTING
A. Sprinkler Mains: Test sprinkler main only for a period of
twelve (12) to fourteen (14) hours under normal pressure. I
leaks occur, replace joint or joints and repeattest.
B. Complete tests prior to backfilling. Sufficient backfill material
may be placed in trenches between fittings to ensure stability
of line under pressure. In each case, leave fittings and
couplings open to visual inspection full period of test.
3.10 FINALADJUSTMENT
A. After installation has been completed, make final adjustment
of sprinkler system in preparation for Owner Authorized
Representative's final inspection.
B. Completely flush system to remove debris from lines by
removing nozzle from heads on and of lines and turning on
system.
C. Check sprinklers for proper operation and proper alignment for
direction of throw.
D. Check each section of spray heads for operating pressure and
balance to other sections by use of flow adjustment on top of
each valve.
E. Check nozzling for proper coverage. Prevailing wind
conditions may indicate that arch of angle of spray should be
other than shown on drawings. In this case, change nozzles
to provide correct coverage and famish date to Owner
Authorized Representative with each change.
3.11 SYSTEM DEMONSTRATION
A. Instruct Owners personnel in operation and maintenance of
system including adjusting of sprinkler heads. Use operation
and maintenance manual for basis of demonstration.
