Found¡tion Repair of \ilestem Color¡do
Re. Ficlding Residcnce: 20 Silver Mountrin l)rive,
Ironbridge Subdivision, Garfield County' CO.
Our office originally inspected the noted residence on Dec. I l, 2018. The subject
residence is a singlc story wood ftamed structure over a crawl space with an attached
vehicular garage. The residential portion of the home measures, in plan, approximately
30'-4" east-to-west by 60'-8" north-to-south. The home was originally constructed with
continuous concrete foundation walls and continuous concrete footings. The crawl space
is separated into two (2)-15 foot wide sections which are separated by a continuous, 56
foot lon, interior concrete foundation wall. The perimeter foundation walls had previously
been stabilized with the installation of thirty five (35) hydraulically driven piers.
Our office issued construction documents on December 21,2018 to address the
stabilization ofthe 5ó foot long interior foundation wall. Those documents specified the
installation of seven (7) hydraulically driven steel piles to be installed along the interior
wall. The construction documents specified the location of each pier and the required
"Safe Working Load" that each pier is to support.
Foundation Repair ofWestern Colorado installed the seven (7) steel piers
beginning on January 31 and February 01 of 2019. They subsequently hydraulically
loaded the piers and lifted and reJeveled the center portion of the home. Our office
coordin¿ted with Keith Davis of Foundation Repair of Westem Colorado during the
construction phase. Subsequent to the foundation repair Keith Davis provided a'Pier
Summary" and "Pier Analysis."
Our ofñce reviewed those documents. The Pier Summary includes the driven
depth of each pier and the amount of lift at each pier. The driven depths indicate the
depth at which the piers encountered the underlying granular bearing soils. The driven
depths were as expected: they varied from 59 feet to 72 feet. The lifts, as documented,
were successfi¡I, and were as anticipated: the lift heights varied from l/8" to 718" .
It is my professional opinion that the foundation repairs have been successfully
completed by Foundation Repair of Western Colorado in accordance with the
construction documents issued by our office.
