Provide as indicated or specified. Galvanize after fabrication where
practicable. Repair damage to galvanized coatings using ASTM A 780 zinc
rich paint for galvanizing damaged by handling, transporting, cutting,
welding, or bolting. Do not heat surfaces to which repair paint has been
applied.

FIELD QUALITY CONTROL
Perform field tests, and provide labor, equipment, and incidentals required
for testing[, except that electric power for field tests will be furnished
as set forth in Division 1]. The Contracting Officer shall be notified in
writing of defective welds, bolts, nuts, and washers within 7 working days
of the date of weld inspection.

Visual Inspection
**************************************************************************
NOTE: For jobs in Iceland, in lieu of AWS welders
and inspectors, use "Technological Institute of
Iceland" certified welders and inspectors.
**************************************************************************
AWS D1.1/D1.1M. Furnish the services of AWS-certified welding inspectors
for fabrication and erection inspection and testing and verification
inspections. Welding inspectors shall visually inspect and mark welds,
including fillet weld end returns.
3.8.1.2
Nondestructive Testing
**************************************************************************
NOTE: The designer shall indicate the location of
test welds and types of testing desired. The
following information is presented as guidance. Dye
penetrant testing detects small surface defects by
enhancing the visibility of the flaw. Magnetic
particle testing detects surface cracks and
near-surface cracks; this test provides more
information than the dye penetrant testing, and for
approximately the same cost. Ultrasonic and
radiographic testing detect surface and internal
cracks, delaminations, lack of fusion, and density
and thickness variations; these tests offer
basically the same information, but their usage is
limited by location and type of weld. Generally,
fillet welds can only be dye penetrant or magnetic
particle tested. Complete penetration welds at butt
joints should be radiographically tested; all other
complete penetration welds should be ultrasonically
tested.
**************************************************************************
AWS D1.1/D1.1M. Test locations shall be [as indicated] [selected by the
Contracting Officer]. If more than [20] [_____] percent of welds made by a
welder contain defects identified by testing, then all welds made by that
welder shall be tested by radiographic or ultrasonic testing, as approved
by the Contracting Officer. When all welds made by an individual welder
