AREA OF DISTURBANCE All excavation areas shall be marked out in advance of excavation by OWNER or AGENT. All sod within the delineated area will be removed and disposed of offsite. 4. EXCAVATION OF EXISTING SAND All sand and drainage materials shall be excavated from the bunker cavity. Any resulting excavated native soil will be stocked piled and used in the reconstitution of the bunker edges and slopes to a maximum of 25 degrees. Contractor will perform removal of the sand and drainage materials in a manner to minimize equipment damage to the bunker complex and surrounding area. Any damage resulting from the removal of the sand and drainage materials will be repaired by Contractor to the approval of OWNER or AGENT.

Sand bunker edges will be marked for trimming by OWNER or AGENT. The cavity edges shall be excavated vertically to a depth of six (6) inches. All bunker slopes will not exceed the angle of repose of chosen bunker sand and will be checked by a digital level to the satisfaction of OWNER or AGENT and Contractor will not be allowed to reconstruct any slopes in excess of the angle of repose of the bunker sand. Where soil material prevents proper foundation preparation at the proposed elevation, the Contractor shall deepen excavation to a level where a proper foundation can be prepared. Any materials removed shall be replaced with acceptable fill until stable at proposed grade. Sand limits will be painted in the field by OWNER or AGENT.

Drainage of sand bunkers shall be accommodated by a drainage trench or multiple trenches connecting to each other, each trench measuring eight (8) inches wide and twelve (12) inches deep connecting into an acceptable and functional outfall pipe. Contractor is responsible for ensuring outfall pipe exiting the bunker cavity is not restricted and functioning Docusign Envelope ID: 06528EA8-C8FB-4176-8C2E-D53F24B897F0
