About this file
This is a shop inspection materials, products, and equipment exhibit for a Miscellaneous Construction via Job Order Contracting (JOC) Request for Proposal issued by Los Angeles World Airports (LAWA). The document establishes comprehensive inspection requirements for materials and fabricated items to be incorporated into facility repair, alteration, and minor new construction projects at LAX and VNY. LAWA anticipates awarding JOC contracts up to a combined value of $6,000,000 with an expected three-year contract term. The exhibit provides detailed specifications for shop inspection protocols across numerous material and equipment categories, including metal fabrications, electrical equipment, HVAC systems, concrete products, coatings, and mechanical equipment, with 37 numbered notes clarifying inspection requirements and exemptions for specific item types.
The document establishes that contractors bear responsibility for providing only materials and fabricated items that fully comply with contract documents and all inspection and testing requirements, regardless of specific shop inspection notations. Critical inspection requirements apply to welded ferrous or non-ferrous metals, high-strength bolting with ASTM A-325 or A-490 bolts, reinforced concrete products, specified protective coatings, electrical equipment rated at 600 volts and higher, and HVAC components. Certain standardized or catalog items, including flexible ductwork, fixed windows, galvanized sheet metal ductwork, and pre-fabricated assemblies meeting nationally recognized quality standards such as UL Listing or ISO-9001-2000, are exempt from shop inspection. Physical and chemical testing required by specifications must be performed by approved testing laboratories or the City of Los Angeles Bureau of Standards.

REQUEST FOR PROPOSAL
MISC CONSTRUCTION VIA JOC
Los Angeles World Airports
SHOP INSPECTION MATERIALS, PRODUCTS AND EQUIPMENT
General:
The requirements for shop inspection are delineated in the Contract Documents. In addition, items requiring shop inspection will be so stated in the submittal/sample reviewer’s comments. However, lack of such notation does not relieve the contractor of the responsibility to provide only materials and fabricated items to be incorporated into the project that fully comply with the contract documents including all inspection and testing requirements.
Without waiving any specific requirement of the Contract Documents, the following items of equipment and/or material are examples of, but are not limited to, those items that are subject to shop inspections.

NOTES:
1. Fabrication of ferrous or non-ferrous metals, which may include welding, high strength bolting or non-destruction testing shall be shop inspec ted .
2. Bolting with ASTM A-325 bolts, ASTM A-490 bolts or other alternate fasteners shall require shop inspection. Bolting with ASTM A-307 bolts does not require shop inspection.
3. Reinforcing steel will be sampled at the source through the Material Control Group.
4. All forging and castings shall be inspected at the foundry, approved and stamped prior to delivery to the job site.
5. Steel and aluminum guardrails require shop inspection for welding and specified coatings.
6. Metal door and frame fabrication requires shop inspection.
7. Pressure vessels, tanks; boilers and related equipment require inspection of fabrication, welding, and testing.
8. Concrete, asphalt concrete, and mix designs are inspected at the batch plant. These products are plant inspected for conformance to specifications and verification by the Inspector.
9. Both pre-cast and pre-stressed concrete shall receive shop inspection and approval before delivery to the job site.
10. Street lighting standards of steel, aluminum or concrete are required to be shop inspected .
11. Reinforced precast concrete vaults, catch basins, and pipe are required to be shop inspected (See Note 9). Manhole shafts and grade rings without reinforcement or linings do not require shop inspection. Gaskets used for reinforced concrete pipe require testing.
12. FGRC and FGRG (Fiberglass Reinforced Concrete and Fiberglass Reinforced Gypsum) shall be manufactured in an approved facility and be shop inspected.
13. Mortar, grout, and gypsum shall be inspected at the batch plant, unless the products are mixed at the job site from approved packages under the inspection of the Engineer.
14. Concrete Masonry Units (CMU) shall be inspected and sampled at the job site.
15. Lining and coating of ductile iron pipe and fiberglass pipe, as well as welded suppo1ts, are subject to shop inspection. Non-welded pipe supports which can be classified as standard or catalog items are exempt. Vitrified Clay Pipe (VCP) will be inspected and tested by the Physical Laboratory of the City of Los Angeles, Bureau of Standards.
16. Shop inspection is not required for lumber, unless it is treated lumber. Glue-laminated products do not require shop inspection. Each "Gl ue Lam" comes with an individual Certificate of Compliance.
17. Millwork and wood products are not required to be shop inspected unless the Specifications call for equivalency or inspection by the Woodworking Institute of California.
