Chanel, Inc. retained EI Associates to design and construct a new Screening and Applied Research Laboratory on the second floor of a former warehouse addition. The former warehouse area consisted of a small office, production working areas, storage racks, and miscellaneous equipment. The former area also served as the corridor between manufacturing areas on the second floor. The scope of work was to remove the existing office, racks, equipment, etc. and to convert the area into the new Screening and Applied Research Laboratory. The new laboratory includes office areas for the Executive Director, administrative and research personnel, and a conference room; Histology, Molecular Biology and Biochemistry lab areas; a Cell Culture lab with an airlock; sterilization, dark room, cold room, microscopy, and storage rooms. The pre-existing Service Corridor was maintained between the manufacturing areas. The roof of the building was modified to incorporate the installation of clerestory windows over the area from the Cell Culture Lab to the Conference Room (approximately 62 lf. in length). The new lab and corridor areas are heated and air-conditioned. The new Cell Culture Lab and airlock incorporates a separate self-contained HEPA fan module and a roof mounted exhaust fan to maintain the area in a negative pressure condition in relation to the surrounding areas. The rooftop mounted HVAC equipment was placed over the storage room area as far as possible from the executive office and conference room.
