Rapid Installment of Modular Precast Civil Infrastructure

The bridges, built roughly sixty years ago, had reached the end of their service lives and were suffering from deterioration. The concrete of the bridge decks was in poor condition. The steel beams under the concrete decks were also in need of repair. MassDOT replaced the steel beams and concrete decks, which together make up the part of the bridge called the superstructure. The bridges’ piers and abutments, which make up the bridges’ substructures, were in good condition. MassDOT repaired the fourteen bridge substructures and revised them to fit the replacement superstructures.

93 Fast Bridge Replacement System Now Being Utilized Throughout US

“… FDE Hydro™ prototype precast concrete module has wide potential for applications, and with adaptation of its design to actual project sites, can be used not only as a non-overflow structure, but also as an overflow (spillway), outlet and intake hydraulic structure. Further adaptation of design can be expected based on actual application for a temporary cofferdam, repair of existing dams and hydraulic structures, and new dam and hydraulic structures. The modularization concept has the potential of wide application and can be customized to any low head dam site. It offers the advantage of high quality control of precast concrete, increased design standardization, and reduces on-site construction time. It also has the flexibility to be combined with other traditional construction and concreting means and methods”.
