616.03 Construction Requirements.
(A) Installation.
(1) General. The irrigation system shown in the contract is
diagrammatic only. Provide the pipe fittings or substitute other pipe
fittings necessary to complete the connections shown in the contract.
Alterations and changes in the layout may occur to conform to the
ground conditions and to obtain full and adequate coverage of water.
Do not change or alter the system as planned without prior acceptance
by the Engineer.
Ream the pipes after being cut and clean and free the pipes from dirt
or other foreign matter. Make the metal to metal screwed joints with
an accepted non‑soluble and nontoxic lubricant on the male thread
only.
Excavate the necessary trenches and other openings a minimum of 18
inches of depth or to the required depth shown in the contract.
Excavate the additional depth and width where required, to ease
valves, reaction blocks, concrete jackets, rock removal, connections
to other mains or to clear subsurface obstructions. Trenches shall be
of sufficient width to permit snaking of plastic pipe not connected by
rubber ring‑type fittings. The Contractor need not snake the pipe
connected with rubber ring‑type fittings.
Trenches for plastic pipe shall be smooth and free of jagged rubble or
sharp objects that will cause abrupt bending stresses and uneven
weight distribution during backfilling operations. Before backfilling
the pipe line trenches in an area that the Contractor will water,:

Set the risers for sprinklers on slopes approximately perpendicular to
the plane of the slope or half‑way between perpendicular to slope and
vertical for best coverage. Install each series of sprinklers and
adjust and test operate the nozzles to establish the location on the
slope and proper angle of the risers.
If the location of a supply line interferes with the drilling of plant
holes, locate the plant holes to clear the supply lines. Do not
install supply lines through plant holes except in the installation of
emitters or bubble heads.
Install the vertical spring action check valves on the sprinkler
risers or swing joints shown in the contract or specified by the
Engineer.
Before the Contractor removes or disturbs markers showing the location
of existing cross‑over conduits, mark the conduit location on the
pavement.
Connect the underground metallic pipes, valves or fittings made of
dissimilar metals through a dielectric coupling or bushing. Separate
these pipes physically from other metal objects a minimum of one‑eight
inch. The Contractor may require non‑conducting spacers that will
insure physical separation of pipe from foreign objects as decided by
the Engineer.
Before any portion of the pipeline on the supply side of a control
valve is backfilled, expel the air from the line. Then turn the water
and maintain at full pressure for not less than 8 consecutive hours.
Also, before any portion of the pipeline on the discharge side of a
control valve is backfilled, do a similar test except the test shall
be for a duration of one hour. Repair leaks that develop in the
portion of the system installed by the Contractor and replace
defective materials at no cost to the State. Plug or cap the pipe
where the Contractor will install sprinklers while making this test.
