Re: Lot 81, Huntington Hills Filing No. 5
506 St. Michaels Drive; Fort Collins, Colorado
Dear Mr. Bonnema,
Shear Engineering Corporation was present during caisson drilling and concrete placement for
the above referenced site on Monday, September 15, 1997. The soils within the excavation were
noted at this time. The soils noted at the bottom of the basement excavation, and throughout the
excavation, consisted primarily of claystones and weathered claystones. The soils noted are
generally consistent with those noted by Earth Engineering Consultants in their geotechnical
investigation report for the Huntington Hills Filing No. 5 area titled Subsurface Exploration
Report for Huntington Hills P.U.D. 5th filing. A caisson type foundation was recommended for
this area.
Waterproofing will not be required. At a minimum, all foundation walls shall be dampproofed to
within 12" of the proposed finished grade according to the requirements of "91 UBC, Appendix
Chapter 29, Waterproofing and dampproofmg foundations".
Caisson construction was performed in substantial conformance with the foundation plan for this
residence which was prepared by Shear Engineering Corporation. Concrete was placed
immediately after drilling.
If you have any questions concerning our caisson construction observations, please call at (970)
226-5334.
