About this file
This is a technical cross-section drawing document for the India Range Berm project in Massachusetts, which involves the removal and replacement of munitions-impacted soils. The project requires removal of the top 40 inches of existing vegetation and soils down to the inner liner mat, followed by installation of select sand fill material and erosion control systems across the entire berm. Key specifications include screening soil to a maximum particle size of 1/8 inch for select sand fill, placement of 4 inches of topsoil on all disturbed areas, and installation of Tensar-SC-150 BN erosion control matting on all slopes. The berm cross-section indicates varying widths and heights, with detailed specifications for material placement, compaction, and slope configurations. All work must commence after October 1, 2026, and be 100 percent complete by December 30, 2026.
The technical specifications outline the material composition and installation requirements for berm restoration, including the removal and proper screening of existing materials, placement of core fill and select sand fill layers, and application of erosion control fabric and topsoil to prevent erosion on slopes steeper than 2:1. The project involves both site preparation through debris and rock removal and final restoration through hydro seeding. No pricing information, bidding timeline, site visit schedules, or other commercial terms are detailed in this technical drawing document.
