Dear Mr. Callender:
This will confirm the discussion held March 27, 1983 between Mr. Andrew
Mireku of your staff and Mr. Michael Nagy, Engineering Review Section
and Mr. Nagy's subsequent discussion with you on April 9, relative to new
column supports in the two Emergency Exit structures.
As you know, the new column footings as proposed in your plan submission
of February 29, 1984 are extremely close to the tops of the two existing
sewers.
It was our recommendation that the column loads be transmitted to the
subgrade of the sewer(s) through some sort of a load transfer mechanism
e.g. grade beams, etc.
This recommendation was also.discussed with Mr. Frank Flores of Metro
North.
It is our understanding that you are now investigating design alternatives
along these lines.
Therefore, our review of this project will continue upon receipt of three
(3) sets of plans revised pursuant to the above. Your submission should
include longitudinal and cross section views showing the sewer(s) in re
lation to the proposed work.
We have arranged for our Maintenance Engineering Unit to conduct an interior
inspection of both sewers in the near future.
' i:"- Very truly yours.
S' FREDERICK NOVOTNY, P.E., CHIEF
Div. of Sewer Regulation &
Control, Bureau of Sewers
