Construction Observation Report # 1
Project GWCU – Rexburg Branch Project Number 19473
Location HWY 191 and University Blvd Date & Time Tuesday August 10th,
12:00 p.m.
Architect BPA Weather Sunny, clear
Contractor R&O Observer McKay Parrish
Persons Present: Steve Welch – R&O, Cade – Virgin Concrete
Project Status Summary: Foundation walls are being formed
Items of Note: I met with Steve on site and we discussed the following items:
Item No.: Item: Follow-Up / Action Required: Initials Photo:
1-1
Rebar and anchor bolt shop drawings
were not submitted and no rebar cages
were installed for column piers or at
holdown locations as shown in details
3/S2.2, 4/S2.2 and 1/S2.3. It also
appears that all vertical wall dowels were
wet stabbed into the footings.
Because the footing concrete is not fully cured
(it was poured on Monday, August 9th), dowels
using epoxy into uncured concrete have a
significant reduction in tension capacity.
Several options to address the missing
reinforcement were discussed, including the
option to lengthen and lap the threaded rod
anchors at holdown locations. The contractor
submitted RFI #3 for ARW Engineers response
regarding repair options.
#1, #2
1-2
All anchor bolts are to be tied in place
prior to pouring the piers and foundation
walls.
The anchor bolt types and locations were
discussed with the contractor. The contractor
indicated that they would tie anchor bolts in
place prior to pouring piers and walls.
Questions regarding column locations were
discussed and the contractor was advised to
coordinate all dimensions with architectural
drawings and to submit anchor bolt shop
drawings for review.
N/A
1-3
As indicated in note D.1.d on sheet S0.1
and note 8 in the footing and foundation
notes on sheet S1.1, the contractor is
responsible to verify footing elevations
and grades prior to pouring the footings
and walls. All exterior foundations shall
bear a minimum of 36” below the lowest
adjacent final grade as indicated in the
structural notes on sheet S0.1 and in the
Geotechnical Report. Cade (Virgin
Concrete) indicated that he was aware
that the bottom of footings did not appear
to be low enough prior to pouring the
footings.
At locations where finish grade to bottom of
footing is less than 36”, the contractor is to pour
a 6” thick concrete frost wall around specific
locations of the building as shown in the
attached detail. This skirt is not required along
gridline K where the footings step down for the
drive-up canopy, or at locations where concrete
pads or walks are set at finish floor elevations.
This frost wall can be soil formed, 3,000 psi
concrete, and does not require dowels or
reinforcement.

1-4
The cantilevered column footing at the
drive-thru canopy was discussed, and
because anchor bolt shop drawings have
not been submitted, the proposed anchor
bolts on side were not correct.
The contractor indicated that they would install
the 1” diameter A449 anchor bolts at these
columns as indicated in detail 2/S2.2

Item No.: Item: Follow-Up / Action Required: Initials Photo:
1-5 Rebar clearance around foundation wall
penetrations was discussed.
There are foundation wall blockouts proposed
in various locations around the building. At
locations where blockouts occur, the contractor
is to adjust the rebar as required to allow for
required rebar clear cover as indicated in detail
4/S2.1 and as outlined the structural notes.
N/A
1-6
Dowels between the foundation wall and
interior slab on grade were not yet
installed.
As shown in detail 7/S2.2 and 8/S2.2, the
contractor is to install #4 dowels at 24” o.c.
around the entire structure. At the time of our
visit the walls had not yet been formed and
dowels had not yet been installed.
