a) Cont. wall footing (with vertical dowels for CMU wall as per note 8) type WF26 along grids A between lines 8 thru
11 completed.
b) Cont. wall footing (with vertical dowels for CMU wall & openings as per note 8 & 9/S4.0 and concrete tie columns
type CC2 [x3]) type WF26 with integrated column pads type F40 (x2) along line 11 between grids A thru E.3
completed.
c) Cont. wall footing (with vertical dowels for CMU wall as per note 8) type WF26 along grids E.2 between lines 8 thru
11 completed.

thru proposed line 12 completed.
e) Cont. wall footing (with vertical dowels for CMU wall as per note 9) type WF20 along proposed line 12 between
grids D.1 thru D.6 completed.
f) Cont. wall footing (with vertical dowels for CMU wall as per note 8) type WF26 along grids D.6 between lines 11
thru proposed line 12 completed.
2. Column pad footings as per S2.0, S1.1 & S4.0/S4.2:

The above mentioned reinforcing steel placement was found to be performed in substantial compliance with the reference
documents except (see below ↓↓↓ *)
(*) as per S1.1 “column / base plate schedule: the bottom hex nut shall be “tack welded secured”. SUNCOR did not include
a clarification/approval question for omission of the tack weld under dwg. Sheet AB1 “approver note”. As per approver note
#2 a plate washer was approved above the previously mentioned hex nut. This plate was found to be loose (floating) not
secured preventing displacement at the time of conc. placement. GC to provide clarification for the observed AS BUILT
conditions. For items 2g & 2h.

Not sure how that missed the schedule. Yes, the reinforcement that has been installed is correct. The thickened slab
should be minimum 12” thick and 1’‐6” wide. Let me know if that is conforming in size.

Mark and Pedro:
I’ve spoken with Jim this morning, and clarified a couple of things, that might help with yesterdays questions. The
question relates to the thickened slab detail 3/S4.2. The reinforcing is not specified in that detail. As currently installed,
there are 3 #5 bars at 12” and the transverse bars are # 5’s at 12” on center. Please confirm the currently installed
reinforcing is adequate.

Brian,
Please let me know if the information on the TS16 snip applies now that the slab is fully demolished.
Installed the three #5 bottom & transverse bars but there is nothing to dowel into because existing slab is gone.

On sheet S2.3 , the Non‐load bearing masonry plan, there are TS16 designations. I’m assuming this is referring to
Thickened Slab. However, I can’t find where TS16 is designated. They are not listed in the Foundation Schedule on S1.1
Can you please let me know the size and reinforcing required for the non‐load bearing wall foundations?
