1.
SCOPE
This standard defines the MINIMUM extent of review of vendor and sub-contractor
fabrication procedures which shall be carried out by the MAIN CONTRACTOR.
2.
PURPOSE
2.1
The purpose of this standard is to state the OWNER's requirements regarding the review of
documents related to fabrication, welding and NDE as an instrument of quality control.
3.
DEFINITIONS.
Fabrication procedures are defined as the following:

Material control procedures.

Welding Procedures (These shall consist of a welding procedure specification (WPS) and a
weld procedure qualification record (PQR).

Non destructive testing procedure (radiography, ultrasonic, magnetic particle or dye
penetrant crack detection).

Forming procedures for dished ends of vessels and pulled bends for piping.

Heat treatment procedures (except those which involve treatment of the complete item in a
furnace).

Internal lining procedures.

Pressure test procedures.

Bolt tensioning procedures.
4.
WELDING STANDARDS
4.1
Welding and NDE of equipment and pipe shall comply with the TOSS and National Codes
listed in table 1.
(This table is provided for convenience and is not intended to diminish or alter the
requirements of the PROJECT STANDARDS for particular equipment.)

REVIEW OF PROCEDURES
5.1
When required by Table 1 of this TOSS, Welding and Manufacturing Procedures shall be
submitted by vendors for review by MAIN CONTRACTOR. Where Table 1 indicates
OPTIONAL submission of fabrication procedures MAIN CONTRACTOR shall assess, on the
basis of critical service/fabrication complexity, whether to review procedures for specific
items.
5.2
MAIN CONTRACTOR shall be responsible for reviewing those vendor and sub contractor
fabrication procedures indicated in Table 1. MAIN CONTRACTOR shall ensure that the
fabrication well be of adequate quality, will comply with the referenced codes and standards
and will be fit for service, by reviewing and commenting on the procedures which do not
comply with the codes and standards called up in the requisition and ensuring that the
vendor/sub-contractor complies with such comments.
5.3
MAIN CONTRACTOR shall submit the fabrication procedures (accompanied by MAIN
CONTRACTOR's REVIEW. This submission shall be done in parallel with transmitting
comments to the vendor/sub-contractor.
5.4
The OWNER will advise MAIN CONTRACTOR when there is any disagreement with the
procedure and/or comments thereon.
6.
NDE REQUIIREMENTS
MAIN CONTRACTOR shall ensure that the vendor/sub-contractor complies fully with the
PROJECT STANDARDS.
7.
PACKAGE UNIT
MAIN CONTRACTOR shall review fabrication procedures for equipment and piping in each
package unit as for each individual component item.
Alternatively he shall ensure by inspection that the supplier of the package complies with
para 5.1 above in respect to sub-suppliers' fabrication procedures. In either event the
requirements of para’s 5.1 , 5.2 and 5.3 apply.
