Projects

The scope of this design-build project included the replacement of two bridges: BIN 1040750 NYS Route 209 (3-span continuous steel girder bridge with a total span of 402 feet) over Rochester Creek and BIN 1019700 NYS Route 28 (7-span continuous steel girder bridge with a total span of 994 feet) over Esopus Creek. KC’s geotechnical scope of work included geotechnical investigation, conducting soil borings to depths exceeding 100 feet, and laboratory testing of soil samples; evaluation of design soil parameters and subsurface soil conditions based on borings; review of maximum loading conditions; selection of the foundation type; design and analysis of steel pipe piles extending to more than 100 feet; and L-pile analysis to determine maximum lateral deflections, pile group analysis to determine group efficiency, and settlement analysis for the embankment area. Piles were designed for severe erosion conditions with meandering river flow around the pier foundations. A modified pile foundation design was developed using closed end pipe piles to increase the individual geotechnical pile capacity and to minimize the concrete quantity, which resulted in reduced cost and an expedited construction schedule. Additionally, the scope of work included preparation of working drawings with material notes and specifications, recommendations for pile installation, and testing and inspection requirements.
