In one weekend, the MaineDOT replaced a 60-year-old structurally deficient bridge, carrying I-295 over Veranda Street in Portland Maine. Work began to remove the existing structure on Friday at 7 p.m. and by Monday at 7 a.m. the new bridge was in place, paved, striped and open to traffic.

To reduce the long-term congestion of a multi-year replacement and increase the safety of the traveling public and workers during construction, the bridge replacement was completed using Accelerated Bridge Construction (ABC). The method of ABC selected for this project involved building the upper portion of the new bridge to the side of the existing one on temporary supports. At the same time, the new bridge foundations were built beneath the existing bridge. Then, while the roadways were closed, the new bridge was lifted and driven into place using a self-propelled modular transporter (SPMT).

Please join us for a joint meeting with ASCE on Thursday, January 19th at the Sheraton at Sable Oaks for a presentation by:

Come join this combined event between SEANH, SEAMass, and SEAM.

754 Congress is currently in construction using a new framing system: the Deltabeam frame. It is combined with hollow core slabs to allow for a fire rated slim floor.

Constructed as a podium type structure that allows for a shallow floor assembly as well as an integrated fire rating of 3 hours. These characteristics are achieved on the Longfellow hotel, the first Deltabeam project in New England!

Join us on January 12th at 9:00 am for breakfast + site visit of the project with Mark Johanson from Peikko.

Please join us for a virtual presentation of Structural Engineering for SoFi Stadium in Los Angeles, California.
SoFi Stadium is the world-class home of the Los Angeles Chargers and World Champion Los Angeles Rams in Inglewood, California. It has already hosted a Super Bowl and is soon to host the 2023 College Football National Championship and the 2028 Opening and Closing Ceremonies of the Olympics. Located on the former site of the Hollywood Park Racetrack, the unique site is said to be the only plot of land in the Los Angeles area that could host a project of this aspirational scale. However, it sits close in proximity to an active fault and directly below flight paths to and from LAX. An approximately 1 million square-foot roof canopy with select operable panels covers the stadium and the surrounding American Airlines Plaza and sits on some of the largest seismic isolators used in the United States. To keep the roof canopy below the height limit required by the proximity to LAX, the stadium was depressed 100 feet deep in the ground. This cavernous excavation is one of the largest ever achieved near an active fault and is accomplished through a specially engineered Mechanically Stabilized Earth (MSE) wall. The stadium’s bowl structure sits entirely within this excavation and remains structurally independent from both the roof canopy and the MSE wall. This structural separation presented further opportunities for innovation as access to the bowl from the surrounding grade was still essential and the upper levels of the stadium required wide concourses that extended out past the limits of the excavation. Each of these challenges was met with unique structural solutions.
