Attention: 'Mr. Phil Travis
Re: Foundation Visual Inspection
Bonnie Barlow

Grapevine, TX 76051
Dear Mr. Travis:
Independent Foundation Engineers, 'Inc., visited the above referenced .residence to
conduct a .visual inspection of the foundation repairs done by your company. These
piers were installed as shown in the service plan by 1st Choice Foundation Repair. It
is our professional opinion that these repairs are in compliance with 'FHA standards.
At the time of the inspection all piers were installed. The piers have been properly
installed in accordance with methods typical to the foundation repair industry. The
objective of foundation repair is to lift and support the foundation. Lifts seldom return
the foundation to the as new constructed condition; Because of foundation weakness
or excessive weight (such as fireplaces) and as a consequence some slopes may
remain in a repaired area.
It must be understood that no foundation can be made risk -free from future
movement. This recently completed work was to address foundation corrections only
in the location where the repairs were conducted. There are many Variables that can
negatively impact the stability of a foundation. Some of these items are tree roots,
environmental /climate factors, plumbing leaks, ` inadequate drainage conditions
around a foundation, inadequate site preparation by the builder, original foundation
design and construction, inadequate moisture maintenance by the homeowner, etc,
It is the responsibility of the foundation repair contractor, 1' Choice Foundation
Repair to furnish the homeowner a valid warranty, and no warranty is issued or
implied by this inspection or report. Liability is strictly limited to the fee paid for this
report.

Sincerely, w
