BKF provided On-call surveying services for the six-mile, three-station Bay Area Rapid Transit (BART) extension from the Colma Station to the San Francisco International Airport including researching, compiling, and resolving historical records to resolve the right-of-way. As part of this effort, BKF successfully completed GPS control surveys to establish and perpetuate monumentation for over 180 private and public parcels. The extension’s corridor spanned through Caltrans, PCJPB S.F.P.U.C., San Mateo County, and local City and private rights of way.
BKF’s efforts also included the preparation of appraisal maps, right-of-way maps, renewal of survey of entire corridor and encroachment exhibits, the preparation of aerial and underground easements for overhead structures and utilities, topographic surveys, densification of geodetic control, and construction support. BKF was responsible for surveying the location of over 300 utility crossings.
