|  | C.) | Staff provided the TAC a review of the Rule Development
  workshop to be held August 7th at the next Commission meeting
  regarding the proposed rule for screen enclosure.  The TAC reviewed the attached preliminary
  text of the proposed rule development “Alternative Design Method for Screen
  Enclosures” and recommended that the Commission adopts the proposed rule “Rule
  61G20-1.002” as is. THE PRELIMINARY TEXT OF THE
  PROPOSED RULE DEVELOPMENT IS AS FOLLWS: 61G20-1.002   Alternative Design Method for Screen Enclosures. (1) The purpose of this Rule is to
  provide an alternate method for designing aluminum screen enclosures as
  defined by the Florida Building Code permitting the loads of the structural
  frame to be based on portions of the screen in the screen walls removed, retracted,
  moved to the open position or cut.  The
  use of framing materials other than aluminum is allowed in accordance with
  section 104.11 of the Florida Building Code, Building. The method
  applies only to walls and roofs with 100% screen. The provisions of Chapter 1
  of the FBC, Building shall govern the administration and enforcement of this
  Rule. 
 
 
 
 (2) Where screen
  enclosures are designed in accordance with the screen removal alternates of
  this rule, removable screen may consist of removable panels, retractable
  panels, or by designating specific screen panels in the design in which the
  screen is to be removed by cutting the screen. Removable panels shall be removed,
  retractable panels shall be placed in the retracted position without
  increasing the load on the affected area. Screen designated in the design to
  be cut shall be completely cut when wind speeds are forecast to exceed 75
  mph. (3)
  Where screen enclosures designed in accordance with the screen removal
  alternates of this rule serve as the barrier required by the Florida Building
  Code at Sections 424.2.17 and R4101.17.1, the required minimum height of the
  barrier shall be maintained when screen panels are retracted, removed, moved
  to the open position, or cut. (4)
  Where screen enclosures are designed in accordance with the screen removal
  alternates of this rule, retractable screen panels, removable screen panels,
  and screen panels identified to be cut shall be clearly identified on
  adjacent structural members with highly visible permanent labels, at each
  panel, or by other means approved by the local building department. (5)
  Where screen enclosures are designed in accordance with the screen removal
  alternates of this rule, the retraction of screen panels, removal of screen
  panels, or cutting of screen panels shall not require the use of ladders or
  scaffolding. (6)
  Engineering documents submitted with building permit applications shall
  identify the panels to be removed, retracted, opened, or cut. | 
|  | D.) | After
  discussion, the TAC provides the following recommendation regarding request
  for Declaratory Statement request
  DS2012-052 by Kavita A. Vallabhaneni 
  of the Baltimore Aircoil Company.  Lavrich recommend using
  language proposed earlier by the Mechanical TAC for both Question 1 and 2 -2nd
  Gascon. Majority in favor. Question 1: To the
  question, Does the
  Florida Statute 553.844(4) exempt exposed mechanical equipment, including the
  cooling tower structural system, from design for wind loads in accordance
  with the Florida Building Code?, the answer is yes, if mechanical
  equipment is fastened to a
  roof or installed on the ground in compliance with the code using rated
  stands, platforms, curbs, slabs, or other means it is deemed to comply with
  the wind resistance requirements of the 2007 Florida Building Code, as amended. Question 2: To the question,
  Does Senate Bill 704
  (Building Construction and Inspection), which was signed by Governor Rick
  Scott, extend the expiration of FS 553.844 until 2013?, the answer is
  yes, HB
  704 provides for extending the expiration of an exemption from the wind resistance
  requirements of the Florida Building Code that are specific to enclosure
  of exposed mechanical equipment or appliances until the effective date of the
  2013 Florida Building Code. |
