Re: Lot 40, Courtyards at Miramont P.U.D., Second Filing
5000 Boardwalk Drive, #40; Ft. Collins, Colorado
Dear Mr, Albrecht,
A representative from Shear Engineering Corporation was present at the above referenced site on
Thursday, March 4, 1999 and Monday, March 29, 1999 in order to conduct caisson construction
observations. A representative of Shear Engineering Corporation was present on Wednesday,
March 10, 1999 and Wednesday, April 7, 1999 in order to conduct foundation wall steel
placement observations. All observations were made in order to verify caisson construction and
foundation wall steel placement was completed in compliance with the recommendations and
specifications provided with the foundation plan for this lot, prepared by Shear Engineering
Corporation, dated November, 1998. Foundation excavation observations were conducted on
Thursday, March 4, 1999, the date of initial caisson observations.
The soils noted at the bottom of the upper crawlspace and garage excavation consisted of sandy,
silty clay, sandstone and claystone. The soils noted at the bottom of the basement excavation
consisted primarily of weathered claystonelsandstone. The soils were somewhat consistent with
those noted in the geotechnical investigation reports for properties immediately adjacent to
Courtyards at Miramont P.U.D., Second Filing. Boring Log B-4 provided by Earth Engineering
Consultants, Inc. in their geotechnical investigation report titled "Subsurface Exploration Report
Proposed Oak Hill Apartments", was located immediately north of Lot 40. The bore log
indicated sandy clay to an approximate nine foot (9') depth with sandstone below the sandy
clays.
Due to the nature of the soils noted, which had been previously observed in several adjacent lots,
a caisson foundation system was utilized. Similar conditions were originally noted with Lot 43.
A drilled pier (caisson) foundation system was recommended for Lot 43 by Terracon
geotechnical engineers in a geotechnical investigation report for Lot 43, titled "Geotechnical
Engineering Report Home 43, the Courtyards at Miramont'; Terracon Project No. 20975151,
report dated October 13, 1997. Caisson foundations had been provided on Lots 39 and 41 on
each side of this site.
Caisson construction observations made by Shear Engineering Corporation on Thursday, March
4, 1999 were for basement caissons only. These observations indicated that caisson construction
was completed in compliance with the recommendations and specifications provided with the
foundation plan for this site, dated November, 1998. Also in compliance with the
recommendations of the subsurface investigation report for Lot 43.

A representative of Shear Engineering Corporation was present on Wednesday, March 10, 1999
in order to conduct foundation wall steel placement observations for the basement foundation
wall. Foundation wall installation was completed in substantial compliance with the direction of
the foundation plan for this site.
Caisson construction observations made by Shear Engineering Corporation on Monday, March
29, 1999 were for upper caissons only. These observations indicated that caisson construction
was completed in compliance with the recommendations and specifications provided with the
foundation plan for this site, dated November, 1998. Also in compliance with the
recommendations of the subsurface investigation report for Lot 43.
A representative of Shear Engineering Corporation was present on Wednesday, April 7, 1999 in
order to conduct foundation wall steel placement observations for the upper short foundation
walls. Foundation wall installation was completed in substantial compliance with the direction of
the foundation plan for this site.
A perimeter drain system was installed according to the recommendations of Terracon
• Consultants Western, Inc. in their geotechnical investigation report for Lot 43. Waterproofing is
not required. All foundation walls were dampproofed according to the requirements of 1991
UBC, Appendix Chapter 29, Waterproofing and Dampproofing Foundations.
If you have any questions concerning our observations, please call (970) 226-5334.
