OVERVIEW: As requested by the owner/representative of the above referenced project (client), the Groundworks inspector visited the project and performed a visual inspection of
readily accessible foundation areas (walls and piers) and associated structural framing elements. Unless noted below, destructive testing and evaluation was not performed. Based on this
inspection, the Groundworks Inspector and the client agreed to the following "Scope-Of-Work".
IMG Push Pier Mod PP21617-34 QUANTITY:[SEE PLAN - PAGE 2]
SPACING (Typ):[+/-12"]
A portion of the structure is settling and needs to be stabilized.
STRUCTURE DESCRIPTION:

DESIGN CALCULATIONS:
2,500 plf
8 feet
• Using the wall load and pier spacing indicated above, the load on each pier will be:
20,000 lbs [SEE NOTE 1 BELOW]
• Using a Factor of Saftey of 2, the minimum driving force will be:
40,000 lbs
DESIGN COMMENTS:

• Based on wall loading and building characteristics outlined in the front page of this report.
of this report, assume a wall load of:

GENERAL COMMENTARY
The recommendations provided herein are based on our understanding of the project and subsurface
characteristics at the time of this report. Based on actual field conditions, helical piles may be installed instead
of push piers. If differing project conditions are encountered, Groundworks field personel shall notify
Engineering Department immediately for resolution.
Unless determined by a site specific soil boring and laboratory soils anlysis, the bearing capacity (net allowable
soil pressure) referenced in the first page of this report is based on our experience with soils in the project area
as well as the “Presumptive Load-Bearing Values” as outlined in the referenced version of the IRC. Any
perimeter pier may be installed on the interior or the exterior of the structure at the discretion of the
Contractor.It should be noted that subsurface conditions can vary across the site due to natural occurence or
