Additional <br />consideration of this adjacent to the existing building is provided in Section C.4. If adequate oversizing <br />cannot be achieved, we should be consulted as additional recommendations may apply. <br />C.2.c. Excavated Slopes <br />Based on the borings, we anticipate on -site soils in excavations will generally consist of sands and silty <br />sands. These soils are typically considered as Type C Soil under OSHA (Occupational Safety and Health <br />Administration) guidelines. OSHA guidelines indicate unsupported excavations in Type C soils should <br />have a gradient no steeper than 1 1/2H:1V. <br />A-7111" <br />INILK ILC. <br />
