Frequently Asked Questions

What is geotechnical engineering and why do I need a soils exploration report?

A geotechnical engineer is a civil engineer who specializes in design of foundation systems considering the strength of the soils, expansive soils, potential hazards (i.e. liquefaction, dynamically induced settlement, site geology, site drainage and other earth related considerations. Geotechnical engineering has a basis in a discipline called soil mechanics which provides engineering solutions to determine the insitu strength of soils and predict its future performance. Geotechnical reports are required in the State of California for all residential, large residential additions, commercial and industrial development.

When do I need deputy inspection and why?
Deputy inspection is a specialized inspection service intended to document the quality and strength of materials (i.e. concrete, mortar, grout, welding, etc.) used in development of highly engineering building systems. Some of the areas requiring deputy inspection are: high strength concrete, reinforced concrete, post tension concrete, pre-stressed concrete, high strength masonry construction, shop and field welding, and replacement anchor bolts.
Deputy inspection is performed to document the specialty construction procedures and service strength to be sure it complies with plans and specifications.
What is engineering geology and why do I need this?

Engineering Geology is a study of the earth’s crust as nature has placed the materials. Specifically an engineering geologist aids the geotechnical engineer in evaluation of the stability of an area, the composition of the area relative to natural formation, alluvium, faulting, rock conditions, rock fall potential and other hazards. In addition, the engineering geologist assists and designs lateral systems to help reduce the potential for damage during earthquakes.

Engineering Geology is sometimes required to ensure that development(s) do not encroach active fault systems. Developments need to be adequately designed to protect life safety, resist lateral damage due to the seismic activity.
