design-build Replacement of padelford street Bridge

Steere performed bridge design as a subconsultant for the accelerated design-build replacement of the Padelford Street Bridge (Bridge No. B-08-003) over Route 24 in Berkley, Massachusetts. The project received a 2015 ACEC/NY Platinum Award for Structural Systems and the 2015 CMAA New England Project of the Year (less than $10M).

The new bridge was designed and detailed utilizing accelerated bridge construction (ABC) techniques, including prefabricated bridge units (PBUs) and modular precast substructure elements to minimize the duration of the bridge closure. The PBUs consisted of steel plate girders made composite with a precast concrete deck. Longitudinal closure pours made with rapid set concrete connected the four PBUs and the deck was made continuous over the pier with a cast-in-place link slab. The precast concrete substructure footings, stems, columns, and pier cap units were connected using grouted splice couplers.

Design-Build Team worked collaboratively with the precaster to ensure tolerances could be achieved. Field fit up issues were eliminated by performing 3D modeling, shop fit-up prior to shipping, and the use of templates.
