Backfilling and Site Restoration

The contract encompasses the backfilling of soil and other suitable materials around an installed tank, with strict requirements for proper compaction to ensure structural stability and long-term integrity. The work must be performed in accordance with engineering specifications to prevent settlement, erosion, or damage to the tank and surrounding infrastructure. All materials used for backfilling must meet approved standards, and compaction procedures must be verified through appropriate testing methods to confirm density and stability thresholds. Following backfilling, the site must be restored to its required condition through final grading that matches the original topography and drainage patterns. This includes eliminating any depressions or high spots, reestablishing natural slopes, and ensuring compliance with environmental and safety regulations. The scope of work is focused solely on site restoration after tank installation, with no mention of tank installation itself or additional construction elements. The contract is classified as a subcontract under NAICS code 238990 and is associated with the Montana State Office of the Department of the Interior, though specific performance location and contact details are not provided.
