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.
d) Cont. wall footing (with vertical dowels for CMU wall as per note 9) type WF20 along grids D.1 between lines 11
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:
a) Column footings type F66 at grid-lines B.8x9 & D.5x9 completed (*).
b) Column footings type F90 at grid-lines B.8x10 & D.5x10 completed (*).
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.
