RE: WTC 776.00 Church Street Underpass at Dey Street-New Escalators, Pre liminary Drawings, Borough of Manhattan
Dear Mr. Carlock:
We have completed our review of the preliminary contract drawings submitted with your letter of June 21, 1983. In keeping with our meeting of July 21, 1983, the following point by point discussion should clarify the comments in the marked-up set of plans we are returning.
The submitted plans did not show provisions for support or replacement of the 3’-6" X 2*-4" sewer which runs along the east wall of the BMT Subway in Church Street. The affected area lies approximately between the north and south building lines of Dey Street. Sewer Record Drawing R457, Route 5, Section 1 dated June 19, 1916 shows three (3) distinct types of construction within these limits. Attached are xerox copies of pertinent sections of R457 for your in formation.
As we discussed in the July 21, . meeting it does not seem likely that the brick and concrete sections of sewer can be supported during the proposed construction, i.e., underpinning of Citibank, driving of soldier beams and temporary support of the subway roof at the escalator opening.
