RE: Underpinning (Piering) Project -Final Report
0129 ruverBend Way
Glenwood Springs, CO 81601
In summary, the concrete foundation walls are stabilized. The push piers were installed in accordance
with the manufacturer's recommendation and specifications. The lift was accomplished in a proper
manner by personnel from Foundation Repair of Wes/em Colorado (FRWC).
The attached two drawings show the post-lift elevations and the amount of lift that was attained. The
"Post-Lift Elevations" drawing can be used as a benchmark for future reference.
Prior to lifting on July 27, 2016, the elevation difference was ±9-3/4", and, after lifting, the elevation
difference was ± 1.0". Post lift indicate's the highest elevation is now at the comer of the master bedroom
adjacent to the master bedroom bath. The lowest elevation is on a line from the NW comer of the front
porch to the walk-in garage door from the garage. Generally, the low area of the house is at the front and
along the house/garage common wall.
The garage elevations prior to lifting showed a difference in elevation of ±6-1/8". After piering, the
garage shows an elevation difference of± 1 /2 11
, being lowest at the north, right rear comer.
Other observations are:
• The outer corner of the front porch slab was lifted 13".
• Residential Structural Inspections
• Foundation Design and Plering

• The garage door needs to be adjusted to fit properly.
• Prior to lifting, the settlement that had occurred caused a gap between the top of the concrete
foundation stem walls and the floor structure . This gap has been eliminated, with the foundation
wall and the floor structure now tightly connected .
• The house superstructure does not fit the concrete foundation walls properly. At the east side the
house framing is 5" beyond the outer edge of the foundation wall. At the west side there is as
much as 4" beyond the foundation wall. FRWC personnel measured the distance between the east
and west foundation walls and found them to be within ±1/2" along their entire length. This
suggests that either the superstructure has shifted so much that it is not tight, or the superstructure
was not constructed properly to begin with.
Please call me if you have any questions.
