Common use of Geotechnical Investigation and Report Clause in Contracts

Geotechnical Investigation and Report. The Consultant shall coordinate with ▇▇▇▇▇ and ▇▇▇▇▇, a geotechnical subconsultant, to perform a geotechnical investigation. Through its subconsultant, the Consultant shall: • Provide a geotechnical report for the project area to identify and assess potentially adverse conditions, such as ground fissures, the location of mapped faults, and/or areas of known collapsible or expansive soils. • Obtain necessary permits, notify Underground Services Alert, and provide traffic control and plans as necessary to conduct the field exploration. • Selected samples of the soils and rock (if encountered) obtained from the borings will be tested in a laboratory to determine relevant engineering properties of the on-site soils. Testing will be performed under the direction of a geotechnical engineer, in general accordance with applicable AASHTO, NDOT or accepted local standards. Perform laboratory tests to evaluate physical and engineering properties of the subsurface soils, including in-place moisture content and density, gradation, Atterberg limits, expansivity, solubility, and chemical (salt) considerations. Selection of tests will be based primarily on project needs, actual soil conditions encountered during the drilling activities, and quality and quantity of samples recovered from the planned soil borings. • Address field exploration and laboratory test results in a formal report. The report shall contain the following: o Summarize geologic literature and other available geotechnical reports or studies in the area.
