Subject: Per the attached RFI #70, at Aeration Tank #1 Pass # 1's walls, an existing 1" conduit_ was found to be cast into the existing wall. The conduit runs from an existing control box etween ass #1 & Pass #2 across the eeranon tank influent channel onto the deck. The conduits route across the influent channel is below the existing concrete walkway out to the aeration tanks. This walkway along with the Pass # I walls are to be removed per Drawing S-02 & detail 1 on S-03. This conduit will affect the saw cutting demolition of the wall and the walkway if it is not relocated. Additionally, if the conduit is left in place, it will be cast into the new wall and walk way deck that is shown on Detail 4 on sheet S-07. Additional costs will be present if the conduit is re-routed or if additional labor is required to chip around this conduit during the demolition process. The response stated "the existing V conduit in question feeds power to gates on the East end of the Aeration Tanks. This feed is to be temporarily powered during construction so that the conduit in concrete can ber removed and reconnected when the new concrete in installed.
