LANL MASTER SPECIFICATION

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 Fire POC. 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.

Specification developed for ML-4 projects.  For ML-1 and 2 applications, additional requirements must be added for increased confidence in procurement or execution (and may be added for ML-3), and independent review is required; see ESM Chapter 1 Section Z10 Specifications and Quality sections. Also, for ML-1 (Safety Class) and ML-2 (Safety Significant) sprinkler systems and water supplies only, DOE has issued guidance in DOE-STD-1066; this guidance will exceed NFPA 13 requirements and some expectations in this section, and requirements will need to be added herein.
