Ponte Ave Abutment 2 Support Wall Elevation Reason Code None Question ABR poured the right Support Wall on Abutment #2 at the planned elevation for Abutment #1, which resulted in the wall being 1.02' higher than planned. Attached are two possible solutions for this mistake. Proposed Solution Option A: Pour additional concrete on top of the cap to the same elevation of the Support Wall. Additional concrete at cap will be the same width as the Support Wall and will encapsulate the 5 existing L1 bars. Option B: Pour cap at the planned elevation. 3-L1 bars will be embedded in the cap, the top L1 bar will have 2" of concrete cover. Drill and epoxy dowels down the face of the Support Wall as required to offset the missing L1 bars. Reviewing the rebar supplied, one less wH3 bar was installed than called out in the plans for the height it was poured. Existing top of Support Wall will conflict with the approach slab. The extent of this conflict will be forwarded once it is determined by our surveyors. Only the footings for Abutment 2 have been poured, but neither of the Wing Walls or the other Support Wall. Additional rebar can be added to these walls if needed. Attached Files (none) Section: 3 - Concrete Int.
