0 <br />STRUCTURAL NOTES: <br />REVISIONS <br />R 318.1 Termite Protection. <br />Termite protection shall be provided by registered termiticides, including soil applied pesticides, <br />baiting systems and pesticides applied to wood, or other approved methods of termite protection <br />labeled for use as a preventative treatment to new construction. See Section 202, Registered <br />termiticide. Upon completion of the application of the termite protective treatment, a Certificate of <br />Compliance shall be issued to the building department by the licensed pest control company that <br />contains the following statement: 'The building has received a complete treatment for the prevention <br />of subterranean termites. Treatment is in accordance with rules and laws established by the Florida <br />Department of Agriculture and Consumer Services." <br />R 318.1.1 If soil treatment is used for subterranean termite prevention, the initial chemical soil <br />treatment inside the foundation perimeter shall be done after all excavation, backfilling and <br />compaction is complete. <br />R 318.1.2 If soil treatment is used for subterranean termite prevention, soil area disturbed after initial <br />chemical soil treatment shall be retreated with a chemical soil treatment, including spaces boxed or <br />formed. <br />R 318.1.3 If soil treatment is used for subterranean termite prevention, space in concrete floors boxed <br />out or formed for the subsequent installation of plumbing traps, drains or any other purpose shall be <br />created by using plastic or metal permanently placed forms of sufficient depth to eliminate any <br />planned soil disturbance after initial chemical soil treatment. <br />R 318.1.4 If soil treatment is used for subterranean termite prevention, chemically treated soil shall be <br />protected with a minimum 6 mil vapor retarder to protect against rainfall dilution. If rainfall occurs <br />before vapor retarder placement, re -treatment is required. Any work, including placement of <br />reinforcing steel, done after chemical treatment until the concrete floor is poured, shall be done in <br />such manner as to avoid penetrating or disturbing treated soil. <br />R 318.1.5 If soil treatment is used for subterranean termite prevention, concrete over pour or mortar <br />accumulated along the exterior foundation perimeter shall be removed prior to exterior chemical soil <br />treatment, to enhance vertical penetration of the chemicals. <br />R 318.1.6 If soil treatment is used for subterranean termite prevention, chemical soil treatments shall <br />also be applied under all exterior concrete or grade within 1 foot (305 mm) of the primary structure <br />sidewalls. Also, a vertical chemical barrier shall be applied promptly after construction is completed, <br />including initial landscaping and irrigation/sprinkler installation. Any soil disturbed after the chemical <br />vertical barrier is applied shall be promptly retreated. <br />R 318.1.7 If a registered termiticide formulated and registered as a bait system is used for <br />subterranean termite prevention, Sections 1816.1.1through 1816.1.6 do not apply; however, a signed <br />contract assuring the installation, maintenance and monitoring of the baiting system for a minimum of <br />5 years from the issue of the Certificate of Occupancy shall be provided to the building official prior to <br />the pouring of the slab, and the system must be installed prior to final building approval. <br />,If the baiting system directions for use require a monitoring phase prior to installation of the <br />pesticide active ingredient, the installation of the monitoring phase components shall be <br />deemed to constitute installation of the system. <br />R 318-1.8 If a registered termiticide formulated and registered as a wood treatment is used <br />for subterranean termite prevention, Sections 1816.1.1 through 1816.1.6 do not apply. <br />Application of the wood treatment termiticide shall be as required by label directions for use, <br />and must be completed prior to final building approval. <br />R 318.2 Penetration. <br />Protective sleeves around piping penetrating concrete slab on grade floors shall not be of cellulose <br />containing materials. If soil treatment is used for subterranean termite protection, the sleeve shall <br />have a maximum wall thickness of 0.010 inch (0.254 mm), and be sealed within the slab using a non- <br />corrosive clamping device to eliminate the annular space between the pipe and the sleeve. No <br />termiticides shall be applied inside the sleeve. <br />R 318.3 Cleaning, <br />Cells and cavities in masonry units and air gaps between brick, stone or masonry veneers and the <br />structure shall be cleaned of all non preservative - treatment or non naturally durable wood. or other <br />cellulose - containing material prior to concrete placement. <br />Exceptions: Inorganic material manufactured for closing cells in foundation concrete masonry unit <br />construction or clean earth placed in concrete masonry unit voids below slab level termite treatment is <br />performed. <br />R 318.4 Concrete bearing ledge. <br />Brick, stone or other veneer shall be supported by a concrete bearing ledge at least equal to the total <br />thickness of the brick, stone pr other veneer which is poured integrally with the concrete foundation. <br />No supplemental concrete foundation pours which create a hidden cold joint shall be used without <br />supplemental treatment in the foundation unless there is an approved physical barrier. An approval <br />physical barrier shall also be installed from below the wall sill plate or first block course horizontally to <br />embed in a mortar joint. If masonry veneer extends below grade, a termite protective treatment must <br />be applied to the cavity created between the veneer and the foundation, in lieu of a physical barrier. <br />Exception: Veneer supported by a structural member secured to the foundation sidewall in <br />accordance with ACI 530/ASCE 5/TMS 402, provided at least 6 inch (152 mm) clear inspection space <br />of the foundation sidewall exterior exists between the veneer and the top of any soil, sod, mulch or <br />other landscaping component., deck, apron, porch, walk or any other work immediately adjacent to or <br />adding the structure. <br />R 318.5 Protection against decay and termites. <br />Condensate lines, irrigation / sprinkler system risers for spray heads, and roof downspouts shall <br />discharge at least 1 foot (305 mm) away from the structural sidewall, weather by underground piping, <br />tail extensions or splash blocks. Gutters with downspouts are required on all buildings with eves of <br />less than 6 inches (152 mm) horizontal projection except for gable end rakes or on a roof above <br />another roof. <br />R 318.6.1 All building sites shall be graded to provide drainage under all portions of the building not <br />occupied by basements. <br />R 318.6.2 The foundation and the area encompassed within 1 foot (305 mm) therein shall have all <br />vegetation, stumps, dead roots cardboard, trash and foreign material removed and the fill material <br />shall be free of vegetation and foreign material. The fill shall be compacted to assure adequate <br />support of the foundation. <br />R 318.6.3 After all work is completed, loose wood and debris shall be completely removed from <br />under the building and within 1 foot (305 mm) thereof. All wood forms and supports shall be <br />completely removed. This includes, but is not limited to: wooden grade stakes, forms, contraction <br />spacers, tub trap boxes, plumbing supports, bracing, shoring, forms or other cellulose - containing <br />material placed in any location where such materials are not clearly visible and readily removable <br />prior to completion of the work. Wood shall not be stored in contact with the ground under the <br />building. <br />R 318.7 Inspection for termites. <br />In order to provide for inspection for termite infestation, clearance between exterior wall coverings <br />and final earth grade on the exterior of a building shall not be less than 6 inches (152 mm). <br />Exceptions: <br />1. Paint or decorative cementitious finish less than 5/8 inch (17.1 mm) thick adhered directly to the <br />masonry foundation sidewall. <br />2.
