Ten Post Office Square is a thirteen-story, steel-framed structure with a transitional masonry facade. The building, constructed in phases during the 1920s and 1930s, occupies most of a city block. The facade featured a limestone cornice that...
Cambridge Discovery Park is a 27-acre site with a master plan to build 820,000 sq ft of rentable space. As structural engineer of record, SGH designed three base building structures. Challenges of the project included design modifications for...
The 499 Illinois Street project in Mission Bay is a 500,000 sq ft biotechnology center in two buildings with laboratory, office, retail, and parking. SGH provided structural and building enclosure engineering services for the project that...
Harvard University planned to locate a new science complex above a Massachusetts Water Resources Authority (MWRA) brick masonry pipeline that was over 115 years old. The University was concerned about the impact of construction on the 69 in. high...
Georgetown University desired a new science center to maximize collaboration and interdisciplinary research among the biology, chemistry, and physics departments in order to facilitate scientific discovery and advancement. SGH...
Mount Sinai School of Medicine planned to install DNA sequencers, which are extremely sensitive to vibration, in two rooms of their medical school. The mechanical engineer, Vanderweil Engineers, contacted SGH to evaluate the vibration...
New high-strength reinforcing steel bars (HSRB) are under development in the United States, driven by constructability and economic and environmental incentives. An experimental study was undertaken to compare the low-cycle fatigue behavior of...

Buildings located close to transportation corridors experience structure-borne sound and vibration due to passing traffic which can be disruptive to operation of sensitive equipment in manufacturing, and medical facilities. Structure-borne sound...
Abstract: Real-time hybrid simulation (RTHS) has increasingly been recognized as a powerful methodology to evaluate structural components and systems under realistic operating conditions. The concept of RTHS combines the advantages of both...
Abstract: Construction of buildings in congested urban settings often results in damage to existing structures located on adjacent sites. The underlying cause of damage is typically lack of planning and proper care before or during construction,...
Abstract: New construction projects in congested urban settings commonly require demolition of an existing structure and deep excavation to accommodate several levels of below-grade parking or occupied space associated with the new building. The...
Abstract: This paper summarizes a multiphase analytical and experimental study on evaluating the propensity for small delaminations in fiber-reinforced-plastic (FRP) composite panels to propagate under both static and cyclic (wind) loads. Finite-...
Abstract: Investigation determined whether it was earthquakes, vibrations from nearby construction, or stone deterioration that led to claims of damage to this historic mausoleum.
