This technical specification article is for the building supplier or installer the minimum requirements for a quality and performance level for structural design, material, durability, and workmanship for metal buildings. This specification applies to all projects involving site-erected metal buildings. It is not intended to be directly applicable to shop-fabricated buildings that are shipped to the site as complete units such as those used sometimes for Power Distribution and Control (PDC) or Design Control System (DCS) buildings.
Followings are Specification and technical requirements for Metal Building during installation and erection.
Metal Building Specification and Technical Requirements
- Plans and details have been prepared by Company. The building supplier shall furnish buildings conforming to the dimensions shown therein, for example, length, width, eave height, bay spacing, roof pitch, and interior vertical and horizontal clearances. All buildings for a specific job site shall be of the same style, profile, and color.
- The building shall be the design of a building supplier who is regularly engaged in the fabrication of site-erected metal building structures. The building supplier shall be a member of the Metal Buildings Manufacturers Association and the American Institute of Steel Construction. The standards and criteria listed in Metal Building Installation International Codes and Standards shall be used when applicable in the structural design and fabrication of the buildings addressed in this specification.
- The building supplier shall provide structural components and accessories of material, size, thickness, or shape that conform to standards of his own manufacture and design and that are of sufficient strength to support all design loads, for example, earthquake, dead, live, wind, and auxiliary.
- The materials to be furnished by the building supplier include, but are not limited to, the following:
- Primary Framing • Sliding Doors

- Closures, Mastics, and Sealants • Canopies
- Windows • Insulation
- Service Doors • Interior Architectural Finishes
- Roll-up Doors • Masonry
- All building framing materials shall be completely shop-fabricated to eliminate fabrication on the job site. All parts shall be accurately made and be true to dimension so that they will easily fit together during erection. All material shall be new, unused, and shall be fabricated in a workmanlike manner.
- Fabricated parts shall be identified using an identification mark corresponding to the marking shown on the erection drawings. Markings shall be stamped, stenciled, tagged, or lettered to remain visible after shop painting.
- All material subject to damage during shipment shall be crated or bundled before shipment.
- The building supplier shall submit the following design information to Company according to the contract.
- Anchor bolt setting plan complete with base plate details, anchor bolt sizes, projection, and thread length.
- Certified foundation reactions.
- Letter of certification that building design is in compliance with all applicable building codes.
- Structural analysis calculations.
- Erection drawings.
- As-built erection drawings.
- Load combinations for frame reactions shall be submitted as prescribed in Table 1.
- Product data describing the structural system, roof and wall system, roof and wall accessories, doors and hardware.
- Color chips for wall panel, liner panel, and trim (4 x 4 inch sample).
METAL BUILDING ERECTION
- The erection of the buildings shall be according to appropriate erection drawings, erection guides, and/or other erection documents furnished by the building supplier. It shall be the responsibility of the erector to comply with all of Company’ safety and construction procedures. It is the further responsibility of the erector to determine and provide any and all temporary bracing, shoring, blocking, bridging, and/or securing of components, as required during the erection process.
- Grouting of base plates (when required) shall be performed by the building erector according to Grouting of Equipment and Structural Steel.
- Erection of the metal building, accessories, insulation, and interior finish shall be performed by one of the following:
- Manufacturer’s authorized suppliers and/or franchised dealers.
- Building manufacturer’s crews.
- Other erectors authorized by the manufacturer as trained and qualified to erect that manufacturer’s product. In this case, the manufacturer shall inspect the work and certify its correctness.
