212 725 2121 You will find attached a concrete core report,
including a location plan for the four? cores taken.
Cores No. 2, 3 and 4 were made into the slab and
walls of the twin barrel sewer that runs along the
centerline of Pier 86 in the immediate vicinity of
the proposed entrance/utility building serving the
USS Intrepid Museum activities. They indicate
compressive strengths of 2896, 3846 and 3891 psi.
Core No. 1 was taken to establish the soundness
of the concrete in the existing pier that will sup- ■ ■
port a significant portion of the proposed building.
The 3846 psi compressive strength found is satis
factory for the purpose of our design.
Y/ rs very truly,
Raymond J. deimbuch
