C04 - Attachment 6 - SD_CS-04_Stripping_2022.docx

This is a Construction Specification document (SD-04 Stripping) issued by the Natural Resources Conservation Service (NRCS) for use in the Land Obstruction Removal and Disturbed Land Revegetation contract in South Dakota. The specification outlines requirements for stripping operations, which involve removing topsoil and undesirable materials from borrow areas, foundations, and earth fill areas to expose subsoil reasonably free of roots and organic materials. The excavated earth material suitable for fill shall be placed in designated fill areas, while stripped material appropriate for topsoil shall be stockpiled and placed over disturbed areas as shown on project drawings or as approved by the NRCS inspector. All waste materials must be disposed of according to drawings or NRCS inspector approval.

The document establishes specific technical requirements for foundation stripping and borrow area stripping. Foundation stripping requires removal of loose soil and extension to a reasonably smooth surface in consolidated subsoil, with foundation slopes excavated to a one-to-one gradient or flatter unless otherwise shown on drawings. Borrow area stripping must expose material suitable for earth fill. This specification serves as one of nine attachments to the broader IDIQ solicitation (12FPC126Q0009) for Easement Restoration and Emergency Watershed Protection services, and contractors responding to task orders under this contract must comply with these technical standards for all stripping work performed.
