Improvement at 59th Street
Following a telephone conversation withyou this afternoon I am
diameter sewer in the Park Avenue Tunnel at 59th Street. On
aeach drawing 1 have circled in red the area under considera
tion.
Please note the following facts:
1. The new columns carry lighter dead load (of road deck)
than existing columns to be removed.
2. New columns are all in the same line with respect to
the existing sewer as the existing columns.
3. Footings^which are typical^have been designed for a
maximum of 4 kips per square foot.
I shall appreciate your prompt reply regarding your approval or
comments on the proposed new columns.
Sincerely,
LeRoy Callender/P.C. Consulting Engineers
