In order to satisfy code requirements, subsurface exploration methods are to be selected by the design professional.The number of code-mandated tests is based on the square footage of the project,and the locations of such tests are to be uniformly distributed throughout the project area where the loads would be imposed to the soils.
Depending on the condition of the soils, additional testing may also be required by the design professionals to evaluate slope stability, stratigraphy, soil-bearing capacity, and/or instability due to liquefaction.
Results obtained from pre-construction geotechnical investigations form the basis for the design of project foundations. The design may then require the installation of pile foundations, footings, compacted fills, or any combination thereof. In instances where a project is being constructed on slopes, soil stabilization may also be required.Building codes then require the inspection of foundation work during installation to ensure the soil conditions projected by the design are in place. Additionally, installation of the foundations is to be inspected during construction to confirm the work performed meets the requirements of the contract documents and the local codes.
There are few things that can be worse for a construction project than to complete a project without having performed the required geotechnical analysis or inspection of the foundation work.
We can support you project with qualified geotechnical engineers to meet the needs of the project and the code.
