1956 by three former massachusetts institute of technology professors howard simpson werner gumpertz and frank heger sgh specializes in structural design historic preservation and evaluation of building exteriors . 2 the firm has a reputation for assessing structural or interior damage to buildings . nationally sgh is recognized as an expert on the science and causes of structural failure . for example when mirror glass panels began falling off boston s john hancock tower and had to be temporarily replaced with plywood in 1973 sgh was hired to analyze what went wrong . more recently sgh was hired by the national institute of standards and technology nist to investigate the collapse of new york s world trade center and assess the towers structural response to impact damage and fire after the september 11 2001 attacks . 3 nist retained sgh to develop computer models simulating the towers structural response to aircraft impact and subsequent fires . several studies conducted by nist and its consultants provided input for the sgh study including aircraft impact analysis fire dynamics and heat transfer models . nist also tested structural steel recovered from the wtc site to determine its mechanical and metallurgical properties including temperature dependent thermal expansion modulus plastic flow and creep properties . sgh first developed models of components connections and subsystems of the wtc towers and studied their structural response to fire induced temperatures over time . using results of such studies sgh developed computationally efficient global models of the towers and performed fe analyses from initial impact through each tower s collapse . 4 financial development edit under the leadership of chief executive officer glenn r. bell sgh has experienced dramatic growth over the last decade . as ceo a role he has held since 1995 glenn is responsible for all aspects of management and leadership . in his tenure the firm expanded from two offices with 14
