SCF~/Ces: Drilled pier inspection.
On this date, an H~C Engineering technician arrived at the above ret erenced
jobsite as scheduled for drilled pier inspection at Building B. Upoa arrival,
technician was told of situation a~d decided to discuss with Chris B~tler of
Butler Construction as to what was the purpose of this pier (see attached drawing
for approximate pie: location). No pier designation was provided by contractor.
Chris stated that the purpose of this pier was because two original piers were
too close together a third larger pier was needed :o bridge the other two because
one caved in from original pier hole. Chris also stated he had talked to someone
with HBC about this. Technioiaa% called HB¢ but could not confirmwi:h anyone
there who had ~iscussed pier with Chris Butler. Chris was also asked i: he had
consulte~ with the structural Engineer of Record for the project and he sta:ed
no. Technician informed Chris Butler that if he proceeded with the pier as is,
that HBC would need to report that this pier was not in compliance ~.ith plans a~d
specifications and he agreed. Technician also observed that ~he cr~ne was moved
to this area of the building. It appeared as though it was intende¢ to set tilt
panels on this column line in the next ~ew days which ~ay or may not be enough
time for concrete in this pier to cure and properly hold panel if i~ is set too
soon. Concrete was placed in pie: hole and complete as of l:lSpm 0~ this date.
Rein~0rcing placed i~ pier was not proper for pier of tha~ size. ~ o separate
cages containing six #5 bars each were placed on the east side of p~.er hole and
~ier hole.
did not have balasters to keep rein~o=cing from Couching bottc~ o: ~
Excessive amount of soil :ell to bo:t~n of pier hole when reinforci:~g was placed
in hole by hand and allowed to slide off top of hole. Integrity o£ this pier
should be ques:io~ed. See a~tached sheets ~or recorded data.
