[Soils Testing and Earthwork Observations]

Construction Consulting:

• Recommendations regarding specifications for placement of engineered fill
• Settlement monitoring of engineered fill or the underlying soils
• Recommendations for soil stabilization in areas to support buildings, pavements, and engineered fill
• Cut and fill slope stabilization recommendations

Construction Testing:

• Observe proofrolling of the exposed soils after the topsoil is removed to locate areas which may require additional excavation or rework, and monitor excavating operations to determine when specified materials have been exposed
• Perform laboratory tests on representative fill materials to determine soil characteristics and verify the materials will be acceptable for use as fill – this includes investigating the proposed borrow source prior to earthwork operations beginning
• Perform field density tests to measure percent compaction on engineered fill
• Observe retaining structure construction to verify appropriate components are being implemented per the design drawings - types of structures include boulder walls, gravity walls (i.e. gabion walls), soil nail walls, modular block walls, and geogrid reinforced slopes
• Evaluation of in-place fill material which may include proofrolling, density testing, hand auger borings with penetration testing, and test pits
