Neponset River Bridge
A subsequent engineering study found that the cracks were due to over-stresses in the flexural steel and abrupt termination of flexural steel in a tension zone.

MTA Subway Station Elevator Replacements
Scope/Solutions
Portions of the New York City subway have been open for more than 100 years and many stations do not meet modern accessibility standards. The Metropolitan Transportation Authority (MTA) undertook a project to replace and upgrade elevators at twenty-six subway stations, including nineteen that lacked an accessible entry. SGH consulted on fire life safety aspects of the installations.
SGH worked with the general contractor and the MTA, who served as the Authority Having Jurisdiction for the project. Highlights of our work include:
- Helping establish the code compliance plans for each station and identifying aspects of the project that are subject to code compliance requirements
- Completing a code compliance checklist for each station
- Evaluating the impacts of new exterior canopies and structural members to be installed at specific stations
- Reviewing existing building codes, ADA compliance, the Uniform Code Provisions for Rail Stations, and NFPA 130 to verify elevator compliance
- Assessing existing structural steel framing to determine fireproofing needs and implement structural steel fireproofing, where required.
- Collaborating with the project team to address compliance issues
