Re: New York Exposition & Convention Center
PVC Drainage Connection to City Storm' Sewer
Dear Mr. Farag:
As a follow up to our letter of February 8, 1985 and your
telephone call of last week, I am enclosing the following:
a. Load calculations
b. Johns-Manville "Perma-Loc" brochure
You will note' that the 'anticipated loads and associated
deflection on the proposed 24 in. diameter PVC connections -
are well within the limits allowed by the pipe manufacturer -
and Uni-Bell.
If you require any additional information, please contact me.
Very truly yours,
SYSKA HENNESSY ........... . ________ ■>,.*—-
