The reports of the services requested and performed for the project are attached. We previously evaluated the bearing soils for design of foundations at the site and presented our findings in a report dated May 30, 2014, Job No. 114 179A. The foundation bearing soils exposed at the bottom of the excavation were observed on May 21 and 27, 2014, dowel holes and epoxy placement were observed on May 28, 2014, and fresh concrete placed for the foundation was sampled and tested on May 28 and 30, 2014 according to the project specifications. Based upon inferences drawn from our observation and testing, as documented by the attached daily field reports, it is our professional opinion that the referenced construction has achieved the specified conditions. Please recognize that construction observation and testing are sampling functions that involve direct observation and testing of very limited amount of the overall work to evaluate the construction compliance. If you have any questions or need further assistance, please call our office.
