PROJECT QUESTION: Regarding wall D2 as a whole - the takeoff SF area difference?

Question: Regarding wall D2 as a whole, the takeoff SF area is 13,382 SF and the plan qty is 13,883 SF. Not as far off as originally thought, but still about 500 SF different than the listed plan qty.

Response: The tabulated areas for causeway walls are slightly conservative and based on a rectangular calculation of sheetpile height to length. The actual sheetpile areas will not be rectangular as they will follow the road profile for the top edge. Wall panel D2-G is tabulated correctly however is drawn with an incorrect bottom elevation. The correct bottom elevation of panel D2-G is 922.0. Revised plan sheets 317, 318 will be included in Addendum 3.
