LOGAN INTERNATIONAL AIRPORT
TERMINALS B AND E AND THE GREEN GARAGE
RENOVATIONS, EXPANSIONS
EAST BOSTON, MASSACHUSETTS

Simon Design Engineering performed a Chapter 34 structural building code review of the existing Terminal E annex, formerly known as Terminal D. The existing structure was analyzed and upgraded seismically to facilitate the renovation and expansion of the building which allowed Southwest Airlines to enter the Boston Logan Airport market with new gates and concessions. This 34,000 square-foot renovation project at Logan International Airport provides additional gates for future air carriers, creates new passenger hold room space, develops shell space for a future security checkpoint, and includes a new baggage claim system. A new roof structure was added and floor areas were infilled to create additional occupied space. In addition, there were various existing floor elevations within the space and at the interfaces with adjacent terminal buildings which needed to be adjusted to match.

All MEP systems were upgraded or replaced. The existing moment-frame structure was upgraded with new steel seismic bracing, requiring locations that did not interfere with circulation. New foundations were limited to one additional pile cap located outside the existing footprint, avoiding costly sitework of multiple foundations near existing underground utilities and difficult interior foundation installation.
