At the discretion of the Building Official, more than six inches (6") may be required. In wood frame construction, six inches (6") of clearance shall be maintained from the bottom of any exterior siding to finish grade. Section 1606 CAST IN PLACE CONCRETE. Add new section as follows: Cast in place concrete construction, unreinforced, and reinforced only for shrinkage or t~mperature changes, shall be classified as plain concrete. Plain concrete, other than fill, shall conform to the reauirements for reinforced concrete and have a miuJmun ultimate compressive strength at twenty-eight (28) days of two thousand five hundred pounds (2,500 lbs.) oer sq~mre inch. Except for sidewalks or walkways, slabs on ground or fill shall be a minimun of three and one half inches (3%~") thick and must be re/nforced with a minimum of 6 x 6 - 10 x 10 welded wire mesh, lapped six inches (6"), or its equivalent in reinforcement. Mmke adequate provisions for waterproofing slabs on -15- grade in all structures. Waterproof admixture concrete or membrane on grade shall satisfy this requirement. Termite trea~nent of soil under slabs on grade under structures is required prior to placing concrete. Section 1700.1 (g) GENERAL. Add new paragraph (g) as follows: (g) Ail wood framing, furring, bucks, plates, steads, or any other woodwork coming into contact with any masonry whether the masonry is exterior or interior, shall be pressure treated. Section 1701.3 FOUNDATIONS. Delete and substitute the 'following: Foundations shall be designed and constructed in accordance with Sections 1301 and 1605. Section 1701.4 MUD Sll.l.q. Delete without substitution. Section 1705.1 SIII.~ ON FOUb~ATIONS. Delete existing and substitute the following: Ail masonry shall be finished to provide a true and even bearing surface for wooden structural ~mmbers. Such structural members shall b& securely fastened to the masonry or concrete bearing surface in the following manner: All sills and plates in exterior walls shall be bolted with not less than one half inch (~") diameter bolts of a length to provide a minimmn six inch (6") embedment in the masonry or concrete and spaced not more than four feet (4') apart. There shall be one such bolt within twelve inches (12") of each corner or offset wall. Alternate methods of equal attachment may be used when supported by proper engineering documentation and approved by the Building Official. In exterior wall construction, where foundation walls are not poured monolithic with the footings, bolts must extend through the wall and into the footings, regardless of whether the walls are solid. One half inch (~") steel dowels extending frc~n the footing and adequately lapping full length of the bolts are construed as complying with the rec~rements of this Section. If hollow walls are used, the cell in which the dowels are located must be solidly filled with concrete or grout. Ail foundation sills shall be of approved pressure treated wood for protection against decay and termites.

Add new Section (a) Definition: An aluminun screen enclosure is a structure franed with structural alumin~n having screened walls and screened roof whose primary function is to provide protection from insects and that is erected in a concrete foundation. (b) General: 1. Permit: A permit must be obtained for all screen enclosures. Such plans for drawings as may be deemed'necessary to fully advise and aquaint the Building Official with the location, method of attachement, construction, and material of the installation and the power meter location and drop shall accompany the application and shall be subject to review of the Building Official. Ail plans and specifications shall be prepared and signed and sealed by a professional engineer registered in the State of Florida Unless product approval has been reccranended as provided for in Section 103.6, Alternate Materials. Screen enclosures are structures and shall meet all setbacks required Foundation The minimum monolithic footing shall be 8" x 8" with one (1) f/4 steel reinforcing bar. (b) Exterior walls of all screen enclosures shall be set back a minimun of two inches (2") from edge of slab. 2. Anchors and Connections: (a) Anchors used to fasten the screen enclosure to the slab shall be tested by a recognized testing laboratory and such test results furnished to the Building Official. ~ allowable holding power for each anchor shall be based on the test results with a safety factor of 2.25. Rust resistant approved anchor bolts shall be used. Co) Sheet metal screws will not be permitted under the following conditions: 1. In tension unless the s~rew ~ has a minimun one half inch (~") shank bond. 2. In a moment transferring connection unless the screw has a mJ_ninum of one half inch (~") shank bond. (c) All connections shall be designed for positive fastening with a minimum safety factor of 2.25. for any other structure. (c) Structural Design: 1. (a) -17- (d) Lateral support shall be by self-standing columns or colu~s with braces made of combination c~pression and tension members. Cables are not permissable as required structural supports. (e) Composite section will only be figured as eighty percent (80%0) of unit stress non-composite section. (f) A minimum facia or sub-facia of two inch (2") material properly anchored to the rafter ~nds shall be required to support a screen enclosure. 3. Screening: All screening shall be a minimum of sixty percent (60%) or more open and shall be installed in such manner that it will release frcm the frame ~ith a loading of 10~ per sc~re foot. 4, Design at all members shall be in accordance with Chapter XXVIII of the Standsrd Building Code. 5. Design Loads: Per Chapter XII of Standard Building Code - In addition, all beams will be analyzed for a two hundred pound (200 lb.) concentrated load at mid-span.
