Dear Angie,
The purpose of this letter is to provide a project closeout observation summary for the push pier project at
the above listed address. Final construction photos were provided by your office on November 11th,
2025.
This project scope included the installation of push piers at two existing jack locations at the interior area
of the residence. The project piers/jacks are located at each end of the floor beam supporting the fireplace
above. The provided photos have been reviewed for general conformance with the construction and
demolition parameters I provided on September 2nd, 2025 and listed below.
IT IS STRUCTURALLY ACCEPTABLE TO NOTCH INTO THE EXISTING (2) FOOTINGS BELOW THE
(2) PREVIOUSLY INSTALLED JACKS TO INSTALL THE (2) NEW PIERS BELOW GIVEN THE
FOLLOWING REQUIREMENTS:
1. EXISTING BEAMS DIRECTLY SUPPORTED BY EXISTING JACKS ARE STABILIZED AND SHORED
PRIOR TO CUTTING EXISTING FOOTING OR PIER INSTALLATION.
2. A MINIMUM OF 8"x8" SQUARE AREA OF EXISTING FOOTING CENTERED ON THE EXISTING
JACKS AND NEW PIERS REMAIN UNDAMAGED.
3. THE NEW PIER IS INSTALLED DIRECTLY CENTERED BELOW THE EXISTING JACK TO PREVENT
BENDING IN THE EXISTING FOOTING OR SLIPPING OF EXISTING OR NEW JACK/PIER
ELEMENTS.
THIS INFORMATION IS BASED ON A MAXIMUM JACKING LOAD OF 78,000 LB AND THAT THE GC
WILL MONITOR PROGRESSION OF PIER INSTALLATION AND WILL HALT JACK LOADING IF ANY
SIGNS OF DAMAGE OCCUR.
The piers appear to have been installed in conformance with the above parameters at the indicated
locations. Periodic inspection of the supported structures should be conducted by the owner annually to
ensure project success. All findings shall be reported to the structural engineer. The contractor is
responsible for the conformance of the design parameters, means and methods. A geotechnical engineer
should be consulted for further insight about on-site soil conditions and preventative measures.
