Cedar street over Route 9 bridge replacement D/B (Wellesley, MA)

CDR Maguire was engaged by MassDOT to provide project design review and construction oversight of the work performed by the design-build entity using Accelerated Bridge Construction (ABC) methods on its second “Heavylift” construction bridge project.

As part of the MassDOT Accelerated Bridge Program, the bridge beam will be fabricated and supported on temporary tower with deck concrete placed off site, then Self-propelled motorized transporters (SPMTs) will be used to move the bridge to its location. 72 hour traffic shut down will only be allowed for the existing bridge demo and new bridge erection.

CDR Maguire was responsible for review of all design submissions and construction project management for the bridge and highway work; acceptance of the final construction contract package; review of the Design Build team’s QA/QC control program and submissions; maintaining a record of submittals; and providing part-time on-site inspection services.
