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 26, 2015, Job No. 113 471T. The foundation bearing soils within the building excavation were observed and tested for compaction on December 16 and 17, 2015 and are suitable for the recommended bearing pressure of 1,500 psf. Perimeter grade beam reinforcement steel was observed on January 26, the post-tensioned slab tendons were observed on January 27 and the fresh concrete for the foundation was sampled on January 28, 2016. Tensioning of the tendons was observed on February 3, 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 Sprin gs 719-633-5562 • Silverthorne 970-468-1989 Silich Construction Inc .
