NILES BOULEVARD OVERHEAD BRIDGE REPLACEMENT

FREMONT, CA

Quincy provided a Control Network and performed construction staking services for the replacement of an overhead bridge and roadway approaches located on Niles Boulevard in Fremont. The bridge crosses over BART and UPRR right of way, and as a result, Quincy had to adhere to strict guidelines while performing staking for the bridge bents and abutments. Quincy surveyors performed construction staking activities including, but not limited to: detention basins, swales and other drainage features, utilities and associated structures, curb, gutter and sidewalk, slope staking for the roadway approaches along with other appurtenant structures. Monitoring surveys were performed for the railroad tracks to ensure construction activities did not alter the horizontal or vertical alignment of the tracks.
