Most important projects per specialty
I-93 FAST 14 Rapid Bridge Design-Build Replacement
This unprecedented fast-track, design-build project replaced 14 deteriorated bridge superstructures on I-93 in Medford, MA under the Accelerated Bridge Program during 10 weekends between June and mid-August 2011. The extremely compressed timeframe was “every day critical”. An Ultra-High Performance Concrete achieving 2,000 PSI within 4 hours of final set (~10,000 psi in 28 days) was developed on the project for use in the “closure pour” joining the precast deck modules and completing the deck prior to opening to traffic on Monday mornings.
Fore River Bridge Design-Build Bridge Replacement
The new vertical lift bridge includes two 500-ft-fixed approach spans, earth ramps and all navigable channel dolphins and fenders from Quincy and Weymouth replaced the existing temporary drawbridge. The bridge provides 175 feet of vertical clearance above mean high water when in the open position and 54 feet of vertical clearance in the closed position. The navigable channel increased in width from 175 feet to 250 feet. The construction of the deep foundations and towers was facilitated through the installation of two temporary work trestles 35 feet wide by 200 feet long utilizing 30-inch diameter pipe piles and steel framing.
Longfellow Bridge Design-Build Rehabilitation
This historic 11-span open spandrel steel arch structure with two steel stringer approach spans and is founded on timber pile supported concrete and masonry abutments and piers.
Cedar Street Design-Build Bridge over Route 9
The main objective of the project was to upgrade the deteriorated components of the bridge substructure and replace the existing bridge superstructure with a new bridge deck that has an increased load capacity and 1’-3” greater vertical clearance under the bridge to Route 9 below.
