61G20-1.002 Alterative Design Method for Screen Enclosures
PURPOSE AND EFFECT: The purpose and effect of the proposed rule is to comply with Ch. 2012-13, Laws of Florida, that directed the Florida Building Commission to establish a workgroup to assist the commission in developing a rule for implementing an alternative design method for screen enclosures that allows for the removal of a section of the screen to accommodate high-wind events consistent with the provisions of the Florida Building Code.
SUMMARY: As mandated by law, the proposed rule provides for an alternative screen enclosure design to be required by the Florida Building Code. The proposed alternative is a site-specific engineered design method which allows for cutting, retracting or removing of certain sections of the screen enclosure when winds are forecasted to exceed 75 mph. The proposed alternative is limited in scope to aluminum screen enclosures and provides for labeling and replacement criteria for the screen panels that are designed to be cut.
SUMMARY OF STATEMENT OF ESTIMATED REGULATORY COSTS AND LEGISLATIVE RATIFICATION:
The Agency has determined that this will not have an adverse impact on small business or likely increase directly or indirectly regulatory costs in excess of $200,000 in the aggregate within one year after the implementation of the rule. A SERC has not been prepared by the agency.
The Agency has determined that the proposed rule is not expected to require legislative ratification based on the statement of estimated regulatory costs or if no SERC is required, the information expressly relied upon and described herein: the economic review conducted by the agency.
Any person who wishes to provide information regarding a statement of estimated regulatory costs, or provide a proposal for a lower cost regulatory alternative must do so in writing within 21 days of this notice.

THE FULL TEXT OF THE PROPOSED RULE IS:

61G20-1.002 Alternative Design Method for Screen Enclosure.

(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 Florida Building Code, Building shall govern the administration and enforcement of this Rule.

(a)        Screen enclosure frames designed in accordance with the screen removal alternates of this rule, shall be designed using signed and sealed site-specific engineering and shall be designed in accordance with the wind load provisions of the Florida Building Code, Section 1609.1.1.

(b)       Designs that consider these screen alternates shall comply with Florida Building Code, Building, Section 2002.4 and Table 2002.4 using the 110 mph column as modified by Table 2002.4A with all screen panels in place.

(c)      Designs using strength design or load and resistance factor design in accordance with the Florida Building Code, Building Section 1605.2, or allowable stress design methods of the Florida Building Code, Building, Section 1605.5.3.1 shall be permitted.

(d)       The design shall be by rational analysis or by 3D Finite Element Analysis. Either method will be acceptable.

(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.

(7) Where screen enclosures are designed in accordance with the screen removal alternates of this rule based on removing screen panels by cutting the screen, the contractor shall provide replacement screen for a one-time replacement of all screen and spline designated by the design to be cut.

(8) Where screen enclosures are designed in accordance with the screen removal alternates of this rule, the contractor shall provide written notice to the owner and the local building code enforcement department that the owner must retract, remove, or cut a panel or panels of the screen enclosure in accordance with the project engineering design or the manufacturer’s instructions when wind speeds are expected to exceed 75 mph.
