I inspected the upper terminal building footer repair this afternoon (Sheet S1c). The concrete is
scheduled to be poured on the afternoon of Friday 12/21. The purpose of the inspection was to verify
rebar and footer widths. No layout verification or footer elevations were confirmed. I noted one step
location that is indicated on the drawings as"2'-6 hold". Based on a survey mark (assumed exterior
corner of wall) on the poured footer, it appears that the footer step needs to be moved north by 0'-9.
This dimension is noted as critical due to the potential interference with the first floor joist. See the
attached sketch for further clarification.
I noted a few other minor items that needed to be modified prior to the pour.
1.) Any dirt clumps on the rebar or loose rebar in the forms needs to be removed prior to pouring.
2.) Due to an existing splice at the north footer step, it was not possible to expose 54" of rebar from
the existing footer for splicing. The concrete contractor instead bent the horizontal bars from
the lower footer up vertically. To make this modification work, each corresponding rebar from
the lower footer to the upper footer needs to be tied in three locations along the splice.
3.) Minimum rebar clearance as the top horizontal bars go under the step form needs to be
maintained.
4.) The contractor's changes to the rebar design in the lower step are acceptable.
A Wacker ground heating machine is onsite and was operating at the time of my inspection. At the time
of the inspection the outgoing line of the machine indicated a temperature of 173° and I physically
noted the incoming line was also warm. The forms should be covered until concrete is onsite. Based on
the forecasted high of 45 degrees for Friday's pour, I do not need to come verify the forms are at a
minimum of 30 degrees.
