Dan
As requested. 1 have performed a structural review of the top running crane rail connections for the runway beams
on both the MCC Building (3 T; '_> and Compressor Building (5 Ton) cranes for the above referenced project
The intent of this review w.as not to verify the struct i 1 design or overall installation of these crane rail systems as
that is the responsibility of the bridge crane engineer and stated vendor This letter is to provide a summary of the
review of the ASCE crane rnfl spot (tack) welds that were employed as a method to facilitate the erection of the
runway beam assemblies prior to the installation of the vendor detailed ".1 -Bolts"
After reviewing the crane construction documents and the provided pictures; it appears that the overall structural
integrity rigs not been compromised by these welds and the intent of of the crane system is in compliance with the
attached details from the crane supplier, American Equipment, Inc. Attached to this letter are these pictures
illustrating the welds and the prescribed "J -Bolt" connections. See the crane vendor runway beam connection
details (page 3) for additional information After reviewing the crane rail drawings and the fact that the ASCE rail is
intended to serve as a "runway" for the bridge support beams I see no evidence lo indicate a diminishing of the
intended struct ral adequacy of this system The tkelds in question do not impair either the cap channels or the rails
themselves.
Please feel free tc contact me if you have any questions regarding this letter.
Sincerely.
