RE: Underpinning (Piering) Project-Final Report
0091 River Bend 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 o/Western 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 the lowest point in the house was at the NW corner near the garage. This comer was lifted
8-5/8" to an elevation that is now just J /4" lower than the highest area of the house at the east side of the
front door. The 8-5/8" represents the maximum lift that was attained . Observation of the "Post-Lift
Elevations" drawing indicates the low area of the house is now at the front wall near the hot water heater.
The total elevation difference over the house foundation walls is now ±112". Prior to lifting this elevation
difference was ±7-3/8 11
•
The garage elevations prior to lifting showed a difference of ±8-3/8". After piering the garage shows an
elevation difference of± J /2", being lowest just west of the rear walkout door.
Other observations are:
• As suspected , the two partition walls at the front room and foyer did not come together
completely with the front wall, nor did the sub floo ring in this front room and the SE bedroom
close completely.
• Resi dential Structural Inspections

• The three large steel beams that support the floor structure never were attached properly to the
foundation walls. They were originally too short to reach the walls and are still not long enough
to reach to the foundation walls . These beams are supported by steel jacks; the beams are
supported laterally. I recommend they be attached to the foundation walls for longitudinal
stability . Steel brackets welded to the beams and bolted to the foundation would provide this
stability.
• Three steel rods have been installed through the north and south walls to help bring these walls
together. These two walls tilted outward as they settled.
• The front wall with the stone veneer has straightened vertically in both directions quite a bit.
• The damaged concrete stem wall at the SW corner of the garage should be properly repaired or
replaced. Except for this portion of concrete wall, the foundation walls are in good condition.
Please call me if you have any questions.
