Strip and separately store topsoil on site for later reinstatement landscape works. 8.2.2 Excavation Work Before excavating any public area including roads, footpaths, reserves, and the like, the Contractor shall obtain the approval of Town/County authorities [e.g. DigSafe] and comply with their requirements for public access and fall prevention barriers, alternative traffic arrangements, excavation methods, backfilling, and reinstatement.

Plan, carry out and maintain the work to avoid erosion, contamination, and sedimentation of the site, surrounding areas and drainage systems. 8.2.4 Maximum Slope Limit the slope of embankments to a maximum of 1:4 unless specified otherwise elsewhere in the design documents. Do not exceed the grades recommended in the geotechnical report. Where applicable, depending on the amount of foundation excess soil, soils may be graded on site, compacting to 3500-psi, or removed from the site, based on the tower foundation type as how excess soils will be disposed of. Prior to all site completion, a drainage and weed barrier fabric will be installed throughout the compound area of 50’ X 50’ and then covered with not less than four [4] inches of #1 & 2 washed stone. 8.2.5 Spoil Ground Should unexpected and/or unsuitable material be encountered in the excavation, or soft, wet and unstable areas develop during excavation, consult the geotechnical engineer who carried out the original and/ or undertake supplementary site investigation to determine appropriate remedial works. Submit to the Town, or their authorized representative, details of any alterations to the submitted construction documents resulting from such advice, before undertaking any additional work. 8.2.6 Site Restorations Upon completion of the compound, restore the natural ground surfaces of the site (i.e., the surfaces which the contract does not require to be altered) to the condition existing at the commencement of the work under the contract. 8.2.7 Weed Prevention As necessary, the Contractor shall treat the fenced area with an approved herbicide used in accordance with Local, State, and Federal regulations.
