Our office is the structural engineer of record for the foundation improvements for
the noted residence, and has provided structural foundation construction documents for
the residence. Our office issued construction documents on October 04, 2011.
The foundation improvements include a series of helical piers and helical piers
installed along the lower level, walk -out side (northeast side) of the basement.
Eight (8) helical piers and three (3) helical tiebacks were installed along the northeast side
of the residence. An additional row of five (5) helical piers were installed parallel to the
northeast wall to provide support for a future lower level patio and main level deck.
The contractor for the project is Nathan Moffatt of Hill Builders, Inc. I reviewed
Hill Builders, Inc. proposal for the work prior to commencement. I performed a site
inspection on October 17, 2011 to observe on-going construction. I reviewed the boring
log of pier and tieback installation as provided by Hill Builders, Inc., and compared the
boring log to the exploratory boring log from the original site specific soils report (Report
No,. 101-196-1 by Hepworth-Pawlak, Geotechnical, Inc. (04/13/2006)).
Based upon that review, it is apparent that the helical piers all penetrated through
the upper, fine grained soils, and are embedded in the dense gravels.
It is my professional opinion that the foundation improvements have been
completed as specified on our construction documents.
