The Ralph Landau Building houses the Department of Chemical Engineering at the MIT. It is a modern, seven-story facility designed by architect I.M. Pei, who is known for such structures as the East Wing of the National Gallery in Washington, D.C. and the Pyramid at the Louvre in Paris. The 130,000 square foot building was constructed in 1976.
CBI was engaged to prepare construction documents for a new 2,000 sq. ft. mezzanine within the existing building. The structural framing for the mezzanine consisted on a lightweight concrete slab supported on composite metal deck and wide flange steel beams. Extensive coordination was required to enable the existing laboratory to remain operational during the construction.
