Types of construction are expected to range from cine- <br /> i <br /> or two-story wood frame to four-story office buildings of , say, steel- <br /> frame or concrete construction. Concrete slab-on-grade floors are <br /> expected to be typical. <br /> Study Procedures <br /> Office study included review of published Bolo is li <br /> and stereo air-photo coverage. Subsurface soils data was reviewed <br /> from exploration by Caltrans and ths__office__for several hi_ wa <br /> E <br /> See the attached list of " <br /> JRfane. for specific literature and soils data referenced . <br /> Field study included site reconnaissance and supplemental <br /> "baseline" subsurface soils data obtained by means of seven sampled <br /> test borings to maximum depth 52 ft (estimated elev. -44) . "Undis- <br /> turbed" samples were recovered from the borings by means of 2.0-inch <br /> OD "standard penetration" and 2. 5-inch ID "thin-wall" samplers advanced <br /> with standard 350 ft-lb striking force. Bulk samples were recovered <br /> from shallow hand-dug test pits and drill cuttings. <br /> The borings were logged and soils field-classified by an engineer <br /> IE <br /> or geologist as to consistency, color , gradation, texture, etc. on <br /> � j� <br />
