The two conical exhaust fans on the roof of the CUP are aluminum. Although they will hold up to the
elements better in their natural state, they may be painted. We have directed that they be painted with a flat
"off-white, toward beige" paint color.
I would be happy to address any additional issues you may have.
Sincerely,

RE: Celestica Stainless Steel Boiler Stack
Dear Ted:
Again I wish to present my professional architectural opinion concerning the stainless steel boiler stack. This
stack and its height are required to support the mechanical systems for the entire building. The stack conducts
very high temperature boiler exhaust and if painted the paint will rapidly peel. A field applied paint finish will
not adhere to a stainless steel appliance conducting high temperatures.
Following is a brief history of how the stack got to the existing situation.
The stainless steel stack was specified because of its durability, heat resistance, and ability to resist climatic
elements.
This was a fast track design -build project. In this process all design and system details are not known during
the planning submittal review. They only become apparent as the construction details evolve.
As Planners and Architects we must be able to respond to the rapid requirements and decisions necessary
when dealing with these high technology clients and projects and at the same time attempting to address the
community interests.
This specific situation did not become apparent to the Celestica Team until it was installed. When we
recognized it was an issue with the City, we directed engineering studies to be conducted to mitigate the
problem.
The stack was originally installed to meet engineering disbursement requirements. Additional studies were
conducted to determine if blower fans could be installed to significantly lower the sack height. The cost of
extreme high heat resistant fan motors was astronomical; consequently this option was discarded.
Subsequently, the boiler stack was lowered to the lowest height, which our mechanical engineers identified as
the lowest height for positive emission disbursement.
The top of the stack is as low as it may be located and still function according to design principles. The stack
contains very high temperature boiler exhaust and should not be painted.
This is the type of situation that can occur with a design -build project. We did everything technically possible
to closely meet the City's criteria sand standards. We request you approve the lowered unpainted stainless
steel stack as part of the Administrative Change.
