Diamond Award:
WSP SELLS received a Diamond Award, the highest honor conferred, in the category of Studies, Research and Consulting Services for the firm’s maturity testing for bridge deck replacement for the I-278 Gowanus Expressway Viaduct in Brooklyn, NY, the only interstate highway in Brooklyn, NY and the largest steel viaduct in New York State.
WSP SELLS application of maturity testing for rapid reconstruction of bridge decks is the first application in New York and the first nation-wide ultra-early strength monitoring. The project combined performance and prescriptive requirements on mix design, testing, concrete mixing and curing. Utilizing this research, the firm developed a low-slump workable concrete that could achieve 3,000 psi strength in 15 hours and has low cracking potential. The firm utilized laboratory and field testing using maturity loggers or temperature sensors embedded in concrete rapid deck replacement within a limited time constraint of weekend lane closure. The successful utilization of this new maturity application will lead to state-wide and possibly nation-wide use of the new maturity application and new specifications.
Silver Award:
WSP SELLS received a Silver Award in the category of structural systems for the rehabilitation of Bridge HU 57.53, an undergrade railroad bridge located in the City of Beacon, NY. The bridge has two separate, parallel superstructures, which share common abutments and a center pier and span the mouth of Fishkill Creek, estuarine wetlands. The westernmost structure carries two active Metro-North Hudson Line tracks while the easternmost structure carries a service road utilized by Metro-North Railroad’s Maintenance Department. The object of the construction project was to replace the superstructure and partial substructure of the westernmost bridge while maintaining passenger & freight railroad service by utilizing a high speed temporary track run-a-round to maximize construction efficiency and quality.
