Aun: Scott Henriksen 303 AABC. Suite J Aspen, Colorado 81612 scott@silichhomcs .com Project No. 16-7-438 Subject: Construction Observarion and Testing Completion Letter, Proposed Residence, Lot 74, Ironbridge Development, 1171 River Bend Way, Garfield County, Colorado Gentlemen: As requested, we are providing a summary of our observation and testing services provided for the above referenced project. The reports of the services requested and performed for the subject project are attached. Hepworth-Pawlak Geotechnical (now H-P/Kumnr) previously conducted a subsoil study for design of foundations at the site and presented our findings in a report dated May 29, 2015, Job No. 113 471E. The foundation bearing soils within the building excavation were observed and lested for compaction on April 8 and 14, 2016 and are suitable for the recommended bearing pressure of 1,500 psf. Grade beam reinforcement steel was observed on May 19, the post-tensioned slab tendons were observed on May 20 and the fresh concrete for the foundation was sampled on May 24, 2016. Tensioning of the tendons was observed on May 27, 2016 according to the projecl specifications. The results of the tendon tensioning were submitted to Fuhrmann & Graf for their approval. We did not observe placement of rigid foam insulation along the building perimeter, but since the perimeter grade beam has a minimum depth of 36 inches, it provides adequnle frost protection rather than by insulation. Silich Construction, Inc. September 14, 2016 Page 2 Based upon inferences drawn from our observations 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 observation and testing of very limited amount of the overall work to evaluate the construction compJiance. If you have any questions or need further assistance, please call our office.
