Item C20
BOARD OF COUNTY COMMISSIONERS
AGENDA ITEM SUMMARY
Meeting Date: December 17. 2003
Division: Public Works
Bulk Item: Yes -X- No
Department: Engineering/ConstructionManagemet
AGENDA ITEM WORDING: Approval of Contract Amendment with Harvard Jolly Clees Toppe
Architect, P.A. for Professional Services to redesign the Medical Examiner's Facility.
ITEM BACKGROUND: The existing contract calls for a design based on 155 MPH sustained winds.
This has added $160,000.00 - $200,000.00 to the project cost. Additionally, it is doubtful that all
building components will actually meet this high standard. During design, the County has revised its
policy on wind load requirements - changing it back to ASCE 7 for 150 MPH 3 second gust. By
redesigning this project based on the revised policy we will save $160,000.00 to $200,000.00 in
construction costs.
PREVIOUS REVELANT BOCC ACTION: On January 16, 2002, BOCC approved the contract with
Harvard Jolly Clees Toppe Architects, P.A., to perform architect/engineering services for the Medical
Examiner's Facility for a fee of 6 3/4% of the estimated construction cost, $2,000,000.00. Fee =
$135,000.00.
CONTRACT I AGREEMENT CHANGES: Amended contract for the redesign of the Medical Examiner's
Facility to meet the wind load requirement of 150 mph as defined in the current Building Code.
STAFF RECOMMENDATIONS: Approve as stated above.
TOTAL COST: $29.691.00

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superseded all other code and code modifications.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,
//
. Cobble, AlA
