Geotechnical Engineering Report 12 10 2024 submission

Mavis Store #2296 December 10, 2024 ECS Project No. 44:2100 Page 13 5.2.2 Structural Fill Prior to placement of Structural Fill, representative bulk samples (about 50 pounds) of the off-site borrow should be submitted to ECS for laboratory testing, which will typically include Atterberg limits, natural moisture content, grain-size distribution, and moisture-density relationships (i.e., Proctors) for compaction. Import materials should be tested prior to being hauled to the site to determine if they meet project specifications. Alternatively, Proctor data from other accredited laboratories can be submitted if the test results are dated within 90 days of the submission date. Satisfactory Structural Fill Materials: Materials satisfactory for use as Structural Fill must be free of deleterious materials such as construction debris, wood, glass, ash, trash, refuse, roots and other organic matter; and, conform to the following engineering properties and compaction requirements. Additionally, imported materials for use as Structural Fill must also meet the New Jersey Department of Environmental Protection’s Requirements for Soil and Fill Materials. STRUCTURAL FILL INDEX PROPERTIES Subject Property Liquid Limit < 40 Plasticity Index < 20 Maximum Particle Size 3 inches Fines Content (percent passing the No. 200) 15% maximum Maximum Organic Content 5% by dry weight STRUCTURAL FILL COMPACTION REQUIREMENTS Subject Requirement Compaction Standard Modified Proctor, ASTM D1557 Required Compaction 95% of Maximum Dry Density Moisture Content within -2 to +3 percentage points of optimum

, ASTM D1557 Required Compaction 95% of Maximum Dry Density Moisture Content within -2 to +3 percentage points of optimum Loose Lift Thickness 8 inches Fill Placement: Fill materials should not be placed on frozen soils, on frost-heaved soils, and/or on excessively wet soils. Borrow fill materials should not contain frozen materials at the time of placement, and all frozen or frost-heaved soils should be removed prior to placement of fill soils and aggregates. Excessively wet soils or aggregates should be scarified, aerated, and moisture conditioned. Field testing in accordance with ASTM D6938 using the representative results from ASTM D1557 is recommended at a per lift frequency of not less than one (1) test per 1,500 square feet or a minimum of two (2) tests per lift, whichever more frequent, within the planned building footprint and not less than one (1) test per 2,500 square feet in pavement areas. 5.2.3 On-site Soil Re-use Existing on-site, granular soils consisting of inorganic soils classified as USCS: SM, SC, SW, SP, GW, GP, GM and GC, or a combination of these group symbols, per ASTM D2487, resulting from excavations for foundations may be re-used. The materials should be suitably dry; free of organic matter, debris, and other deleterious material; and should contain no particle sizes greater than 4 inches in the largest dimension.
