'-.rsons, Brinkerhoff, Quade & Douglas, Inc. July 15, 1987 '<^>s Penn Plaza L’ork, NY 10119 c n: Mr. Ahmet Gursoy, Project Manager Re: AMTRAK North Tunnel, Dual Inverted Siphon at West 33rd Street and 11th Avenue, Borough of Manhattan
De a r M r. Gursoy: This in reply to your submittal of plans for the referenced project with your letters dated January 8, 1987 and June 4, 1987, and to your June 30, 1987 submittal of minutes of a meeting held on June 29, 1987. Please be informed of the following comments:
1. Item No. 3 in the minutes states that "Bureau of Sewers has accepted the siphon design hydraulically". This is incorrect. The meeting was held to clarify the relationship between the computation sheets and the contract drawings so that our review could be concluded expeditiously. Hydraulic acceptability can only be given by formal letter from this Department after complete review of all submitted computations and related material. 2. Regarding item No. 2 of your minutes of the meeting, be advised that should your final siphon design computations be found to be deficient, such design may require revision which in turn, may involve changes in sizes and/or elevations of existing or proposed sewers or dimensions of the siphon itself.
3. On drawing No. S-32 of your contract plans you show the existing 3’-0" X 4’-9" combined sewer entering new manhole No. 3 as having a height of 4*-9". Attached herewith for your informatiomn is an extract copy of a contract plan dated July 27, 1939 for the New York Central Railroad Company showing a cross section of this sewer (labeled S-S), indicating that the height is 3’-0".
