Building 77 Rehabilitation
Location: Berkeley, CA
Type of Contract: M, E, P, A
Detailed Scope of Work
Building 77 is a high bay, structural steel industrial facility with 57,000 sq. ft., and a partial floor area of 11,500 sq. ft. The building provides precision welding of both, common and exotic metals, metal sandblasting, ultra high-vacuum cleaning and testing, glass shop, ceramic shop, advance metrology, and large apparatus precision assembly. The purpose of this project is to provide environmental controls appropriate to support precision fabrication accelerator components, detectors, superconducting magnets and other advance scientific equipment for DOE projects worldwide.
The Mechanical and Electrical Systems consist of upgrading the HVAC and environmental exhaust systems, to meet current requirements for control of environmental condition for safety and processes. Installed new exit lights, battery powered emergency lights, and fire detection and alarm system in modified areas. We also replaced existing HVAC equipment and systems which required a full design of various new systems including: cooling tower, air handling units, fume and dust removal equipment, air supply, return, and exhaust ducts, variable air volume boxes, chilled water and heating hot water piping, chilled water and heating hot water circulating pumps. LBNL installed a new utility center to serve Bldg. 77 and 77a including the installation of new chillers, cooling towers, boilers and primary CHW/HW pumps. The Architectural services consisted of construction of a new concrete building to house the new Utility Center. Installation of a thermal insulation to roof and walls to control the interior temperature while minimizing energy use. Installed sound absorptive panels on ceilings and walls to minimize hearing hazard to employees. Upgraded fire rated exit paths to meet building code requirements by installing fire rated doors, frames and hardware as well as fire rated partition at selected locations. ADA designs also included providing disable access to toilet restrooms. Civil/Structural Design included to design the new Building 77B structure, equipment anchoring systems, and construction shoring system. Modifying the existing roof structure and installation of new structural supports for roof mounted mechanical equipment and ductwork. Prepared site-grading work for the new Utility Center. Provided a plan profile drawings for the site piping system, and electric ductbank system.
