This 2200 sq ft expansion of an existing high bay research facility was constructed to expand the available LBNL B77A space to accommodate two specific large research equipment pieces, including a 27,000 pound furnace and 30,000-pound autoclave. A new open bay steel structure with insulated wall and roof panels was constructed to integrate with the existing building. A new roof top mechanical platform and exterior yard were created to accommodate a new dedicated Mechanical and Controls system. Due to the nature of the equipment to be accommodated a new electrical feed was required within the new extension.
