Re: Declaratory Statement on Mechanical Code 304.9 and Rule 9N-3 “State Product Approval System”.

Dear Mr. Modani,

My name is Geoff McLeod of MESA Modular Systems, Inc. My Partner and I have designed and engineered an anchored support pad for the HVAC industry. The material that makes up our pad is a HDPE high strength structural foam, loaded with 2.5% Carbon Black for the best UV stability available according to industry testing and standards. The modular, stackable pads are anchored by a galvanized earth anchor to resist 150mph wind loads. This is a ground level application, not for roof top applications. See attached.

I have two questions in need of clarification;

First question: Can the Commission approve our pad according to Mechanical Code Section 304.9 “other approved material”?

Second Question: Does our anchoring system fall within Rule 9N-3, “State Product Approval System”

Please do not hesitate to email or call my cell at 727-798-7701 with any question.

Sincerely,

Geoff McLeod

President, MESA Modular Systems, Inc.
