SECTION 055000

METAL FABRICATIONS

****************************************************************************************************************

Word file at

This section includes shop fabricated metal items, usually of galvanized or primed painted steel, 12gageor heavier or aluminum, sheet, extruded, or cast. Cast iron, brass, copper, or other metals can readily be added to this section.

If the Project requires metal stairs they may be included in one of the following:

A) Section 05 1000 (i.e., stairs are not specifically called out; however, since they are/contain structural framing, they are included by default), or

B) Section 055100, that will have to be developed by the project since it is not included in the LANL Master Specification.

Metal railings may not be included in this section because they are specified in Section 055213. And the same goes for bar gratings (since they’re in Section 05 5313)outside of their use herein (e.g., ladder treads, etc.).

This section is not to be used as a “shortcut” to 05 1000, Structural Metal Framing. If the Project work involves the AISC 360 Scope then 05 1000 must be used: “…AISC 360…[applies] to the design of the structural steel system or systemswith structural steel acting compositely with reinforced concrete...sets forth criteria for the design, fabrication and erection of structuralsteel buildings and other structures, where other structures are defined asstructures designed, fabricated and erected in a manner similar to buildings, withbuilding-like vertical and lateral load resisting-elements…” And the same goes for work involving AISC 341.

This specification section is for use with LANL ESM Chapter 5, Sections I and II in particular; therefore it is primarily applicable to ML-4 (routine) projects. For ML-1, ML-2, and some ML-3, additional requirements and independent reviews may be required; see ESM Chapter 1 Section Z10 Specifications and Quality sections.

This template must be edited for each project. In doing so, specifier must add job-specific requirements. Brackets are used in the text to indicate designer choices or locations where text must be supplied by the designer. Once the choice is made or text supplied, remove the brackets. The specifications must also be edited to delete specification requirements for processes, items, or designs that are not included in the project -- and specifier’s notes such as these.Additional tailoring requirements are contained in ESM Chapter 1 Section Z10 Att. F, Specifications.

To seek a variance from requirements in the specifications that are applicable, contact the Engineering Standards Manual Structural SpecsPOC. Please contact POC with suggestions for improvement as well.
When assembling a specification package, include applicable specifications from all Divisions, especially Division 1, General requirements.
