Ms. Stephanie Coffer Director of Construction and Planning Monroe County 1100 Simonton Street Key West, Fl 33040 Re: Monroe County Medical Examiner's Facility Crawl Key, Florida HJCT Comm. No. 01160 Dear Ms. Coffer: This letter is in response to our telephone conversation regarding additional construction costs associated with increasing the 3-second wind gust pressure from the code required 150 mph to the requested 190 mph (see attached letter from Jorge Fernandez dated 4-24-03). Many components of the building will be affected by this increase. While the main cost escalation will be in the structure of the building, other affected components include roofing, sheathing, windows, doors, hardware, soffits, etc. Accordingly, we estimate an increase in construction cost from $160,000.00 to $200,000.00. It is our understanding that when the Florida Building Code took effect in early 2002, it superseded all other code and code modifications. Accordingly, you may want to verify if your previously adopted code modification ordinance is still in effect. We look forward to direction from your office concerning this issue, as it affects the design of many building components. Feel free to call with any questions you may have. Sincerely, " \ // .,Y/ .
