The Contractor shall strip all grass, weeds, turf, organic topsoil, roots and the like from the areas subject to earthworks before other operations commence. The stripped topsoil shall be separated from other stripped material and separately stockpiled for future reuse in the locations shown on the approved construction drawings or areas otherwise approved by the Engineer. The stockpiles shall have maximum slopes not steeper than 1v:2h and all changes of grade rounded to conform generally to the surrounding landscape.
The Contractor shall use appropriate equipment and procedures to avoid contamination or otherwise affecting the topsoil’s potential for reuse.
The depth of topsoil stripping shall be sufficient to remove all organic material, turf and significant plant roots such as to expose soil containing an insignificant amount of organic material to the approval of the Engineer. Except where limited by boundaries, existing works or other limiting features, stripping shall extend 2.0m beyond the limits of areas subject to earthworks or construction. The Contractor shall determine the proposed stripping depth prior to starting operations and shall avoid unnecessary over-excavation.
