Focus on Bridges

At Gill Engineering, our firm's singular focus is clear: sound bridge engineering. We bring practical approach to our assignments. Our engineers have solid technical knowledge of structural engineering theory and codes, and we have a behind-the-scenes understanding of the subtleties behind successful bridge projects. Armed with cutting edge technology, our team is well prepared to efficiently develop sound, innovative solutions to your structural engineering challenges.

Accelerated Bridge Construction Technology

ABC technology is increasingly being implemented to expedite construction projects and reduce impacts to the traveling public.  This is a departure from the old practice of utilizing staged construction to maintain traffic over a bridge during its reconstruction.  ABC adopts a “Get In, Get Out and Stay Out” approach that reduces on-site construction time, minimizes traffic impacts and dramatically reduces project costs and durations.  Gill Engineering is a specialist in ABC, having utilized it effectively on several recent Design-Build projects, earning us numerous national engineering awards. Gill has utilized ABC on several recent design/build projects, including:

  • Construction of prefabricated modular deck units, allowing for replacement of 14 bridge superstructures within 10 weekends on the 93 Fast 14 Project.
  • Roll-In using SPMT (self-propelled modular transport) of two-span continuous superstructure fabricated on-site over a 3-day weekend on the Cedar Street Heavy Lift Project. 
  • Design of a gantry crane system to expedite superstructure construction on the Longfellow Bridge.
  • Jacking existing structures intact to increase clearance over CSX RR tracks on 4 bridges
  • Innovative contracting methods, including Design/Build project delivery
