• Evaluate the compaction of the building subgrade by conducting in situ density and moisture <br /> content measurements and hand probing <br /> • Evaluate the compaction of the base rock beneath the building <br /> • Verify that a vapor barrier was installed beneath the building <br /> Members of our geotechnical staff observed the geotechnical-related tasks identified above on an <br /> intermittent and on-call basis. Their observations are summarized in field reports, which were <br /> provided to the design and construction team members and are on file in our office. <br /> To the extent observed, the construction outlined above was completed in general conformance <br /> with the intent of the project plans, specifications, and our geotechnical engineering <br /> recommendations. <br /> ♦ ♦ ♦ <br /> We appreciate the opportunity to work with you on this project.
