The onsite material is assumed to be a sandy lean clay <br /> with an internal friction angle of 26". Where unsuitable soils are found, a subcut may be required and <br /> structural fill shall be placed and compacted to provide an adequate bearing foundation. The above minimum <br /> soil strength parameters shall be verified by the project geotechnical engineer prior to construction. CDP shall <br /> be contacted if the above soil strength parameters cannot be met and a redesign may be required. <br /> Wall layouts and elevations obtained from plans provided by Matt Gerken of Southview Design. <br /> We appreciate the opportunity of providing services to you.
