You've been selected as the geotechnical engineer by a commercial developer. She wants to build a one-story structure with a footprint (plan view) of 50 by 100 ft on a previously developed site. To kick- off the project, she has scheduled a meeting with you, the architect, and the structural engineer. Choose which of the following types of historical information you would review before attending the meeting. Select one: a. Location map, aerial photographs, geologic maps and publications, topographic maps, your internal project files. O b. No review is necessary since the geotechnical study will provide you with all the site information you need.
