During the six-year rehabilitation of the Brightman Street Bridge, SGH provided investigation and concrete design services and performed testing, analysis, and thermal modeling of mass concrete placements.
Constructed in the late 1800s, the Norwottuck Trail Pedestrian Bridge carries the recreational bicycle and walking path over Snell Street. The steel through-girder structure was corroded and the east girder had a large hole. ...
Built in the early 1900s, the pedestrian/equestrian bridge over the Ipswich River at Bradley Palmer State Park was closed because of deterioration. SGH investigated the structure and developed a rehabilitation program, including protection...
The Speen Street Culvert conveys the Beaver Dam Brook and connects Settlement Pond to Fisk Pond in Natick, Massachusetts. The original double-barrel, stone-arch culvert is believed to be over 100 years old. Following the partial...
The 1906 Hoover Mason Trestle at the historic Bethlehem Steel plant transported raw materials on an elevated rail from the ore yard to the plant’s large furnaces. Abandoned for decades, the reinvented trestle is now the backbone of a new,...
The state of U.S. infrastructure and need for funding to improve it has been highlighted through efforts of national engineering organizations such as the American Society of Civil Engineers’ Infrastructure Report Card and the American...
For integral abutment bridge (IAB) design, there is no consensus on the preferable orientation of the piles supporting the abutment, although variations can affect overall bridge behavior and forces in the piles. This paper details a parametric...
