BKF provided on‑call surveying services for the six‑mile, three‑station BART extension from Colma Station to the San Francisco International Airport, supporting one of the region’s most significant transit expansions. As part of this effort, BKF researched, compiled, and resolved extensive historical land‑records to clarify right‑of‑way boundaries throughout a corridor that crossed Caltrans, PCJPB, SFPUC, San Mateo County, local city, and private jurisdictions. The team completed GPS control surveys to establish and preserve monumentation for more than 180 public and private parcels, ensuring accurate and reliable surveying control across the entire alignment.
BKF’s work included preparing appraisal and right‑of‑way maps, updating surveys for the full corridor, and producing encroachment exhibits for overhead and underground utility structures. Additional services included topographic surveys, geodetic control densification, and construction support. BKF also performed parcel surveys for the three BART stations, completed over 300 utility‑crossing surveys using potholing methods, and prepared legal descriptions and plats for approximately 500 parcels. The effort concluded with a 70‑sheet Record of Survey documenting the full BART right‑of‑way, providing a comprehensive and permanent record for the agency.
