A “Geotechnical Investigation” is a necessary, preliminary step in planning a construction project. A thorough investigation will yield critical project information pertaining to foundation, roadway section, and retaining wall design. Subsurface conditions that can significantly impact project design and costs include shallow bedrock, shallow groundwater, slope instability, and compressible and expansive soils. The early identification of subsurface conditions and potential problems is often a major reason for a successful on-time on-budget project.

Nelson Engineering works with owners and design professionals to develop a scope of work appropriate to the project and local conditions. We strive to provide a geotechnical work product that provides clear and succinct earthwork and excavation project information for architects, structural engineers, and contractors. Our geotechnical staff has over 30 years of experience on a wide variety projects, including utilities, dams, Superfund and mine sites, bridges, subdivisions, commercial buildings, and residences. Our in-house soils laboratory and construction materials testing facilities allow for an integrated project approach.
