trench excavations. Any accumulated water shall be promptly removed from the trench to
prevent softening of the trench bottoms and soil changes detrimental to stability of the
subgrade. Although trench size shall be minimized, the trench width and depth shall be such
that proper clearance is provided adjacent to and beneath all parts of the piping and fittings
for placement of the bedding material, cradle, jacket, etc. The minimum clearance on each
side of the piping is 300 mm; the minimum clearance beneath the piping is 150 mm.
C. All piping shall be installed in a continuous envelope of pipe bedding material. The bedding
material shall extend from 150 mm below to 300 mm above the outer parts of the pipe,
fittings, and accessories over the entire width of the excavation. Acceptable bedding
materials/placement shall be as follows:
1. Pipe Bedding: Sand: On-site borrow material, clay to silty fine sands that have been
sampled, tested and approved by the Engineer and which complies with the requirements
specified below under "Civil Works Fuel Hydrants". Place the bedding material such
that the lower quarter of the pipe circumference is in continuous contact with backfill.
Place the material carefully and uniformly up each side of the pipe in 0.15 m layers in a
manner that assures compaction along the sides and haunches. Compact the bedding
material uniformly under and around the pipe.
2. Backfill: Backfill material, which is tested and complies with the requirements specified
below under "Civil Works Fuel Hydrants". Place backfill immediately after the pipe
has been bedded. When required by Section 40980, "Jet A1 Fueling System - Inspection,
Cleaning, Flushing, and Testing", or by the Engineer, leave all joints exposed until all
required testing is performed and accepted. Place and compact trench backfill to
preclude a depression from ultimately forming at the surface along the trench.
D. Complete backfill from top of bedding to grade with backfill. Place backfill materials in
layers not more than 0.25 m in loose depth for material compacted by heavy compaction
equipment and not more than 0.10 m in loose depth for material compacted by hand-operated
equipment. Before compaction, moisten or aerate each layer as necessary to provide
optimum moisture content of the soil material. Compact each layer to the required density
for each area classification as defined below. Place backfill materials evenly adjacent to
piping, tanks, and structures to the required elevations. Do not place layer of loose material
until after compacted layer is tested and accepted by the Engineer.
E. Compaction Density Requirements: Compaction of materials and compaction testing shall be
in accordance with the requirements specified below under, "Civil Works". Results of the
testing shall be submitted to the Engineer for evaluation and approval.
F. Area Classification - Density: Compact soil materials for following area classifications to not
less than the specified in-place density applicable for the type of soil material:
1. Pipe Bedding - Sand: Compact top 150 mm of subgrade and each layer of backfill
material to minimum of 98 percent maximum dry density at 2 percent of optimum
moisture content.
2. Backfill (Balance of Pipe Trench Excavations):

i. Within Structure Lines or Under Pavements: Compact each layer of backfill
material to minimum of 98 percent maximum dry density at 2 percent of
optimum moisture content.
ii. Other areas: Compact each layer of backfill material to minimum of 90 percent
maximum dry density.
G. The full length of each section of pipe shall rest solidly upon the bedding material.
H. Any pipe that has the grade or joint disturbed after being laid shall be taken up and re-laid.
I. Do not lay pipe in water or when trench conditions are, in the judgment of the Engineer,
unsuitable.
J. Anchor pipe, in an approved manner, during installation to prevent flotation prior to
placement in service. If the buoyancy requirements require the installation of concrete
coating or installation of pipe weights, the Contractor shall notify, and obtain prior approval
from, the Engineer, prior to proceeding with these installations.
K. When work is not in progress, securely close open ends of pipe or fittings using approved
expanding type watertight plugs to prevent trench water, earth, or other foreign substance
from entering the pipe or fittings.
L. Pipe coating shall be inspected with an electronic holiday tester in accordance with Section
40980, "Jet A1 Fueling System - Inspection, Cleaning, Flushing, and Testing" prior to
backfilling.

3.6 RADIOGRAPHING AND MAGNETIC PARTICLE TESTING
A. All welds on carbon steel pipe shall be examined by radiographic methods to determine
conformance to the paragraph entitled "Standards of Acceptance". The Contractor shall
employ, at no cost to the Owner, a recognized independent testing laboratory to test the items
indicated below by radiography. All fillet and seal welds shall be tested by magnetic particle
testing method. All costs of testing, including re-testing of repaired welds, shall be borne by
the Contractor. Tests shall be performed for:
1. 100 percent of all circumferential shop welds.
2. 100 percent of all circumferential field welds on underground piping/fittings.
3. Standards of Acceptance: Interpretation of test results for inadequate penetration,
incomplete fusion, porosity or gas pockets, cracks, etc. in welds shall comply with the
requirements set forth under "Standards of Acceptability - Nondestructive Testing" in
API 1104.
B. The Contractor shall cooperate with the testing laboratory and shall give the Owner, the
Engineer, and the testing laboratory adequate advance notice of when welds will be available
for radiographing and that all the work required by the Contractor in connection with the
welding prior to radiographing is properly completed.
C. Laboratory testing report shall be timely submitted, to the Engineer, throughout the progress
of the work, and the Contractor will be notified of any encountered deficiency.
D. Reports of all radiographing and magnetic particle testing shall be prepared in accordance
with the requirements of ANSI B31.4. The reports shall include welder's code, weld
identification and description, whether the weld meets the specification requirements, the
film type and size, and remarks on imperfections. All subsequent report formats shall be in
accordance with the requirements of Section IX of the ASME Code.
E. Radiograph exposure film negatives will be kept on file by the Engineer; the record for such
radiograph film negative will show the date, location of tested weld (coordinate d with weld
location as shown on the Contractor's as-built drawings), area, film number, serial number,
film combination, time, source-film distance, angulation and other pertinent information for
each weld radiographed.
F. A summary of these records along with an expert interpretation of the tests shall be prepared
by the testing laboratory and submitted in a report form for each weld, to the Engineer.
Interpretation of negatives shall be by a Level 3 radiographic technician certified by
examination by the American Society of Non-Destructive Testing.
G. All welds shall be left exposed until all testing (radiographing and magnetic particle) is
completed and welds have been accepted by the Engineer.
H. Acceptance criteria for welds shall be in accordance with ANSI B31.4 and API 1104
requirements for severe cyclic conditions. Welds which do not meet the standards of
acceptability will be judged unacceptable and shall be repaired or cut out and rewelded by
the Contractor as directed by the Engineer at no additional cost to the Owner. Repaired and
rewelded joints shall then be re-radiographed. If the same joint, after the second welding and
radiographing fails again, then the section(s) of involved pipe shall be removed and replaced
at no cost to the Owner.
