Soils and foundation investigation involve soil borings, test pits, CPT sounding, using truck-mounted track-mounted and portable drilling rigs. Standard Penetration Test (SPT) is conducted at 5’ or less intervals. During boring operations, disturbed and undisturbed samples are taken for laboratory testing such as moisture/ density, Plasticity, mechanical analysis, shear strength, and consolidation. Corrosion samples will be taken for corrosion tests if requested. Design and construction recommendations are prepared as a signed document for use by the design team and for submittal to the building departments.
