Overview
Berkeley Lab Master Specifications establish the standard technical requirements for design and construction projects across the Laboratory.
These specifications support consistent design quality, regulatory compliance, and maintainability across Berkeley Lab facilities.
Master Specifications are maintained by Facilities Engineering Document Control using the SpecLink specification management system and are regularly published for use by design consultants and project teams.
