Attn: Mr. Robert Fenstermacher
As requested, a representative from GROUND arrived at the project site to inspect bolted
connections as directed by John with Aspen Leaf.
The following is a summary of the services performed on this date:
1) Inspected anchor bolt installation of Simpson Titan HD ½” screw anchors as per ER
#2173 and found missing and re-located anchors on beam support bracket at Units #9
and #19 on the east wall at two places each. Location is due to HSS tube obstruction –
Item #1 on the Discrepancy List. We also found missing and re-located anchor on beam
support bracket at Unit #19 on the west wall due to concrete thickness – Item #2 on the
Discrepancy List. All other areas were found to be in general compliance with ER
#2173, “with a minimum 100’ of torque” and specifications.
John with Aspen Leaf was notified of these results and received a copy of this report and
Discrepancy List.

Re: Fenstermacher Residence
Ridgeview Square #9 & #19
Rob,
The following are responses to your questions from the framing inspector:
Question #1:
One of the brackets is bolted in with three of the four bolts, but the fourth (top) bolt would have
gone into the HSS member rather than the concrete. Please see photo, attached. Our options for
this appear to be:
a) drill into the HSS and concrete and install the fourth bolt
b) weld the top of the bracket to the HSS
c) leave it with three of four bolts and John indicated that the plans show three bolts
Answer:
C. You can leave it with 3 bolts.
Question #2:
Another bracket is also bolted in with three solid bolts into the wall, but the fourth (top) bolt only
had approx 3 inches of concrete behind it due to the floor being removed in the adjacent unit.
John installed the fourth bolt and epoxied it in (with the inspector watching, to make sure that the
epoxying was done properly) for this, our options appear to be:
a) drill another bolt hole in the bracket, a bit lower and install a fifth bolt into the solid
wall concrete
b) leave it with the three solid bolts and the one bolt that installed/epoxied into the ~3" of
cement.
Answer:
B. You can leave it with 3 solid bolts and the epoxied bolt.
Sincerely,
Sean Molloy, P.E.
Senior Project Engineer
