Soils and Foundations: • Perform testing of foundation excavations to verify design bearing pressure. • Perform density testing on-site to verify necessary compaction has been obtained for fill material, subgrade, and pipe crossings in accordance with AASHTO T99 and Town of Cary Standards and Specifications. • Provide proof-rolling observations for excavated areas of construction as needed after sub-grade elevation has been attained. Identify area of unsuitable soils, recommend remediation, and establish/verify limits and depths where unsuitable soils have been removed. Verify that all unsuitable soils have been removed and replacement material has been properly installed and compacted. Prepare memos identifying quantity of undercut excavation measured at each location. • Perform soil boring for soil type identification and rock. • Identify ground water presence and correction action recommendations if necessary. • Attend weekly and/or monthly coordination meetings as needed as the project progresses. • Other related geotechnical and construction testing services as may arise during construction. Concrete and Masonry: • Provide concrete and grout material sampling and testing (slump, air content, temperature tests, compression tests, etc.) to ensure compliance of materials and placement methods with contract documents. Asphalt: • Collect core samples of asphalt to ensure compliance with required thickness and density stated in the contract documents.
