EASTLINE (2100 Telegraph Avenue)
The planned mixed-use project at 2100 Telegraph will occupy the entire 3.2-acre block, making it one of the largest developable sites in downtown Oakland. Running beneath the site are three concrete tunnel box structures that contain Bay Area Rapid Transit's (BART) rail lines. Langan evaluated the soil and groundwater conditions at the site and developed conclusions and recommendations regarding the site seismicity and seismic hazards, probable foundation types for the new structure(s), foundation settlement behavior, floor slab support, construction considerations, and seismic design criteria in accordance with the 2013 California Building Code. Langan's civil engineering services included performing boundary and topographic surveys and support the project through the initial Planning Application of the project.
