The reports of the services requested and performed for the project are attached. We previously conducted a subsoil study for design of foundations at the site and presented our findings in a report dated October 16, 2015, Job No. 113 471J. The foundation bearing soils within the building excavation were observed and tested for compaction on March 7 and 9, 2016 and are suitable for the recommended bearing pressure of 1,500 psf. Grade beam reinforcement steel was observed on March 22, the post -tensioned slab tendons were observed on March 23 and 24 and the fresh concrete for the foundation was sampled on March 24, 2016. Tensioning of the tendons was observed on March 28, 2016 according to the project specifications. The results of the tendon tensioning were submitted to Fuhrmann & Graf for their approval. We did not observe placement of the rigid foam insulation along the building perimeter, but since the perimeter grade beam has a minimum depth of 36 inches, it provides adequate frost protection rather than by insulation. Based upon inferences drawn from our observation and testing, as documented by the attached daily field and laboratory 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 Parker 303-841-7119 • Colorado Springs 719-633-5562 • Silverthorne 970-468-1989 Silich Construction Inc.
