Dear Mr. Phillips,
Shear Engineering Corporation conducted foundation excavation observations for the above
referenced site on Friday, July 1, 2005. The soils noted at the bottom of the crawlspace
excavation consist primarily of light brown silty sandy clay. The soils noted at the bottom of the
garage excavation also consist primarily of light brown silty sandy clay. The soils noted in the
excavations are generally consistent with the soils profiles provided by Empire Laboratories, Inc.
in the geotechnical investigation report for Eastgate Apartment Complex titled "Report of a Soils
and Foundation investigation and Development Corporation, Fort Collins, Colorado"; E.L.I.
Project Number 1148-72; report dated April 24, 1972.
Boring Logs No. 6 and 10 were the borings taken on this site. Boring Log No. 6 indicated sandy
clay to a depth of four feet (4% underlain by silty sandy clay to a depth of five feet (5'), underlain
by sand, gravel and cobbles to a depth of fifteen feet (15'), the bottom of the boring. Boring Log
No. 10 indicated sandy clay to a depth of three and one half feet (3.5'), underlain by silty sandy
clay to a depth of six and one half feet (6.5% underlain by sand, gravel and cobbles to a depth of
fifteen feet (15% the bottom of the boring.
This lot is suitable for a spread footing foundation system. The foundation plan for the proposed
residence prepared by Shear Engineering Corporation, dated January 2005 was used. Footings
were designed for a maximum allowable bearing capacity of 2,500 pounds per square foot (dead
load plus full live load) and a minimum dead load of 750 pounds per square foot according to the
recommendations of the geotechnical investigation report referenced. It was determined that a
perimeter drain system was not required based on the depth of excavation.
Shear Engineering Corporation was present on Wednesday, July 13, 2005 for footing formwork
and footing reinforcing placement observations. Shear Engineering Corporation was present on
Monday, July 18, 2005 and Wednesday, July 20, 2005 for foundation wall reinforcing placement
observations. These observations were made to confirm that footing formwork and reinforcing
placement and foundation wall reinforcing placement were completed in substantial compliance
with the direction, details and specifications noted on the foundation plan.
All footing formwork and reinforcing placement and foundation wall reinforcing placement was
completed in substantial compliance with the direction, details and specifications noted on the
foundation plan.

Re: Lot 1, Eastgate 2nd Filing (1120 Montgomery Street); Fort Collins, Colorado
Shear Engineering Corporation was present on Monday, July 25, 2005 for foundation wall
dampproofing observations. Dampproofing observations were made to confirm that
dampproofing material and application was completed in substantial compliance with ASTM D-
449 Type II and ASTM D-41 specifications and the federal specification SS-A-701.
Dampproofing (DECO 20) was applied to the exterior face of concrete basement walls that retain
earth and enclosed habitable space. The dampproofing was applied from the top of the footing to
the assumed finished grade elevation. Dampproofing coating material and application (DISSCO
521) meets the ASTM D-449 Type II and ASTM D-41 specifications and the federal
specification SS-A-701.
If you have any questions concerning our observations, please call us at (970) 226-5334
