re:
Cahan Addition
Dear Ms. Turner:
This letter shall serve as explanation for what, on the surface, appears to be a
conflict in the plans as approved by the Developm~n' Review Committee and the
required water line sizes as needed on the site today.
It stems from the fact that the sizes as shown on plans submitted by Walter Nelson
were a reflection of his effort at a "best guess" based on his experience. He
allowed for 1 1/2" pipeline for building service and a 1" line for landscaping. The
problem arises in that none of these portions of the work had actually been
designed yet. In the process of architectural design, building plans and elevations
are generally developed to a point that assures no major changes to consultants
before passing them off for that portion of the work. In that architectural design was
being approved at the same time as site development, Walter did not have at his
disposal accurate loads and information to include in his set. As it turns out, once
the consultants were finished their specifications differed slightly from the original.
The Mechanical Engineer has sized a 2" service line to the building and the
Landscape Engineer required a 1 1/2" line. Therefore, the meter size required for
the site is larger than originally specified on the civil drawings.
I hope this addresses any concerns or questions you might have had about the
r&eent dav2loYmants. If ''?r'6 vu. v2 Ci F+i 'y' Gtii.'.r ei~, pl8a3o viii .'t i'icSiGte t0 vall.
