<br />Do not intermix gravel, stone or gravel crushings, or sand in the
<br />same excays Cion or connected excavations. (See paragraph 8
<br />covering use of soil stabilization and filter fabric to prevent
<br />migration between dissimilar soils).
<br />S. INSTALLATION OF SOIL STABILIZATION/FILTER FABRIC
<br />All pipe trenches will be lined with an approved soil stabiliza-
<br />tion filter fabric, regardless of soil conditions and type of
<br />backfill material used.
<br />Approved materials include the following:
<br />DuPont "Typar" Style 3401 - 4 oz/S.Y.
<br />Monsanto "Bidis" C-22 - 4 oz/S.Y.
<br />Phillips "Supac" Fabric - 4.1 oz/S.Y.
<br />Celanese "Mirsfi" 140 Fabric - 4.1 os/S.Y.
<br />Material should be cut to an appropriate width for the depth and
<br />width of the pipe trench so that there is sufficient material to
<br />overlay the top edges of the trench during pipe installation and
<br />make a complete envelope of the backfill at subgrade as shown on
<br />the drawings with a minimum of 6" lap at the top. Laps of
<br />material along the trench excavation should be a minimum of 2
<br />feet.
<br />6. BEDDING OF PIPE
<br />A minimum 6" deep compacted bed, graded to give the proper slope
<br />or depth of pipe runs, must be laid in trench before pipe runs are
<br />installed. Pipe runs should be fabricated at grade and installed
<br />and properly spaced on the completed bed. After making necessary
<br />connections of runs, branches or fittings which must be made up in
<br />the trench, bed material should be placed back under the piping
<br />andP ro erl acted.
<br />P Y compacted.
<br />7. TESTING_ AND INSPECTION
<br />After all lines have been installed, and before they are back-
<br />filled, lines.are to be disconnected from the tanks, plugged or
<br />capped, subjected to a minimum 50 psi gauge air pressure (or as
<br />required by local or state codes) and checked for leaks with a
<br />"soapy" solution in the presence of the Owner's representative for
<br />a minimum of 30 minutes. Gauges for this test should be
<br />.0-100 psi range.
<br />Air testing.of fiberglass piping is not a recommended practice by
<br />manufacturers unless certain safety precautions are followed.
<br />Contractor about,] obtain appropriate procedures from fiberglass
<br />pipe suppliers and assume responsibility for following same for
<br />prescribed testing pressures. Their recommendations will include
<br />covering pipe between joints, placing sand bags or other
<br />restraints at intervals and numerous safety precautions for
<br />personnel working on site and/or involved in the test or
<br />inspection.
<br />Prior to making the high pressure test in the presence of the
<br />Owner's representative, it is recommended that the contractor
<br />first apply a low pressure 5 psig leak test to insure that all
<br />adapters are securely threaded into place, that adhesive has been
<br />applied to every joint and properly cured. The low pressure leak
<br />test can be applied in a short time, thus, locating any hadly made
<br />joints immediately. The line should be tarefully inspected for
<br />evidence of leakage - either using a soap solution on the points
<br />of Iitening for the hissing sound of escaping air. Once it has
<br />been determined that the tine is tight, the full test pressure
<br />should be applied ,and allowed to remain as long as specified.
<br />After reconnection of all lines and prior to backfilling of same,
<br />the entire system, to include tanks and all lines, is to be
<br />subjected to a final air test of 5 psig for a minimum of one hour
<br />without a measurable loss of pressure. Gauges for this test
<br />should be 0-15 psi range.
<br />The contractor will provide the owner's representative with a
<br />certificate of testing and inspection indicating that the piping
<br />and complete system has been tested in accordance with these
<br />skecificattons and has been found to he tight and in compliance
<br />w th all state and local 'odes oovertnR such an installation.
<br />i Product Pcptng Pressurization During Construction
<br />Upon completion of the "final acrtest" of 5 psi on the entire
<br />cyst ,rx, the prndutt piping systems are In he disconnected
<br />from the submersible pumps .and tapped or pluggeA and a 50 psi
<br />air pressure re-applied and allowed to remain under pressure
<br />until all excavation in the yard and final paving is
<br />completed- Pressure gauges, 0-100 psi range, should he
<br />installed on each product system and monitored each workday
<br />for a sudden loss in pressure which would indicate piping
<br />damage. Steed valves at the gauge should be secured
<br />1plugged) to prevent tampering with the system while
<br />pressurized. Gauges should be accessible/visible for
<br />inspection by the Shell Engineer, either in one of the
<br />dispenser shear clamp boxes or subpump manhole.
<br />8. BACKTILLING OF PIPING
<br />___1,.._ ._- ...
<br />After satisfactory completion of all required testing and inspec-
<br />tion of piping, backfilling of trenches to subgrade elevation
<br />should be completed as required for the material used,
<br />If at becomes necessary during the course of construction to
<br />switch from the standard backfill material to an alternate such as
<br />$and, soli stabilization and filter fabric must he installed as a
<br />• barrier between the two noncompatible materials. Approval of the
<br />owner's representative must be obtained for making such a
<br />substitution.
<br />9. FINAL ITEMS
<br />a. Tanks to be gauged for product level and water. Any measur-
<br />able amount of water will be removed from the system.
<br />b. All product piping is to be bled tarefully for .n r as sub-
