Mr. James G. Carlock, P.E, RE; WTC-C-81; World Trade World Trade Center Project Center, Dey Street Administrator Underpass The Port Authority of N.Y. & N.J. Borough of Manhattan 1 World Trade Center New York, NY 10048 Dear Mr. Carlock; In reply to your latest submittal of revised plans for the referenced project with a letter dated June 15, 1981, please be advised of the following comments:
1) The sectional drawings along the route of the proposed 18" diameter rerouted sewer indicate that the clearances between this sewer and adjacent paralled utility lines located above it will leave insufficient trench width for access to the sewer in the event that replacement should become necessary. Therefore, to minimize the possibilities of replacing this sewer, it is required that the proposed sewer be class 56 Ductile Iron Pipe with "Push On" joints, laid on class "35" concrete cradle on un disturbed soil. It is also required to maintain a 4'-0" minimum clear width over the proposed sewer alignment. A sketch is inserted in the enclosed, marked-up copy of the submitted plans to illustrate the above comment.
2) A complete profile of the proposed, rerouted 18" diameter sewer should be shown in the plans. The profile drawing should indicate all clearances with adjacent crossing structures and other utilities.
3) Drawing WTC-C2-81 shows the proposed 18" diameter sewer to be con nected directly to the existing 3'-6" X 2'-0" brick sewer in Church St. just west of the proposed manhole No.3, without the use of a manhole. Since this method of connection may damage the old existing brick sewer, it is required that a manhole be constructed on the existing sewer to receive the new 18” connection. As a suggestion, to avoid interference with the existing telephone ducts located above the sewer, manhole No. 3 may be re-designed as an L-shaped M.H., with the existing brick sewer located within the horizontal leg of the "L". Details of any such manhole should be submitted for review as part of the contract plans. An existing manhole in proximity to this proposed connection may be eliminated, and necessary modifications made to accommodate the existing 12" diameter catch basin connection.
