Presenter: standard soil testing needs 8–10 ft holes; existing building blocks testing

A presenter explained that standard subsurface investigation for a new development typically occurs in the design phase on a vacant parcel and requires digging multiple test holes to collect soil profiles and infiltration data. The presenter said the team would "dig a few holes uh 8 to 10 ft deep and then we would analyze the soils, we would document the soil profile, we would run infiltration testing in the hole that we dug." The description framed those steps as the basis for the technical data the project team had been asked to provide.
