Box 1190 Fort Collins, Colorado 80522 Attention: Mr. John Shepek Irerracon 301 N. Howes • P.O. Box 503 Fort Collins, Colorado 80521-0503 (970) 484-0359 Fax: (970) 484-0454 Re: Construction Materials Compliance Summary Larimer County AST Installation; Building Permit No. B0303677 614 East Vine Fort Collins, Colorado Project No. 20027044 Dear Mr. Shepek: Earthwork At your request, we reviewed the earthwork materials placed and monitored during construction of the AST pad by Terracon on an "as requested" basis. Our services on the project building have included performing laboratory testing of the soils for suitability to the project specifications and the Geotechnical Engineering Report recommendations (Job No. 03-011) performed by Koechlein Consulting Geotechnical Engineers (dated April 3, 2003). As recommended in the soils investigation, on -site or approved imported soils were suitable for placement during construction. Laboratory tests indicated fill material tested by Terracon met the recommendations as outlined in the geotechnical report. The results of the field and laboratory testing were forwarded for review. In addition, the on -site superintendent and subcontractors were informed on a daily basis of the test results performed. Terracon performed 12 in -place density/compaction tests for the AST site subgrade and fill placement. The tests at the locations indicated met or ultimately achieved (after retesting) the compaction specification requirements. Observation of construction procedures, and physical in -place testing was provided by Terracon personnel on a part-time, as -requested basis. Based upon the limited tests and observations performed, results indicate suitable materials and specified compaction at the locations tested. Our test results represent only the materials at the location and time of testing. Terracon did not direct nor control the fill placement and compaction at the site and does not assume responsibility for the placement, compaction or control of the fill materials. Areas of fill which are not representative of our testing may exist, particularly in common fill areas such as slopes or landscaped outside of proposed construction. The foundation type and specific design for each structure will be recommended based on the particular characteristics of the soil type at foundation depth, and on the basis of further evaluations and observations prior to construction.

The reports indicate compressive strength requirements for the project have been achieved. Reinforcing Steel 264�3 lferracon of 2 tests for physical the specified minimum Terracon provided reinforcing steel placement observation in structural concrete placements as requested. The observations were performed per the provided plans and specifications for the project and have been formally reported to the client and designated parties. Foundation Terracon provided observation of the foundation excavations as requested during construction. A summary of the observations and structural review response items were provided in written reports upon completion. Per the project geotechnical report and observations performed, the foundation has been placed in general accordance with the plans and specifications and were placed on the anticipated bearing material identified in our geotechnical report. This report has been prepared for the exclusive use of providing test data and observations to document the earthwork, concrete, and foundation operations conducted for the proposed project.
