Developing advanced technologies for security, space exploration, healthcare and energy applications, Draper Laboratory consolidated selected research on one floor. Renovations created ISO 4-7 cleanrooms, enabling MEMS and multi-chip module R&D. The bay and chase layout, designed within an existing 1970’s era office building, overcame ceiling height, dispersed utilities, air entrainment, asbestos, hazardous production materials and waste disposal challenges. A new rooftop penthouse contains make-up air and heating. One wing’s process exhaust systems were replaced. The fast track renovation took place in an urban constricted building in Technology Square, Cambridge, housing more than 1,000 employees.
