Subject: Construction Observation and Testing Completion Letter, Proposed
Residence, Lot 267, Ironbridge Development, 0038 River Vista, 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 project are attached. We previously conducted a subsoil study for
design of foundations at the site and presented our findings in a report dated July 27,
2015, Job No. 113 471N.
The foundation bearing soils within the building excavation were observed and tested for
compaction on March 1, 2016 and are suitable for the recommended bearing pressure of
1,500 psf. Perimeter grade beam reinforcement steel was observed on March 15, the
post -tensioned slab tendons were observed on March 16 and the fresh concrete for the
foundation was sampled on March 17, 2016. Tensioning of the tendons was observed on
March 21, 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
