Safety of the occupants, the construction labor and ihe <br /> building structure are of the first priority. In all cases the contractor is responsible to <br /> provide temporary shoring of the structure as required during the repair of deteriorated <br /> framing. <br /> Determine the magnitude of decay that penetrates into ihe structural framing members <br /> using a small flaihead screwdriver or an awl as a test probe. Expose the wood rot and <br /> decay to thg fullest extent possible. Structurally competent wood should•be resistant to <br /> the insertion of the tool. <br /> A�I rot fs to be rem�ved from the framing member and the structure. <br /> Wood Treatment: All structural framing that has had rot removed or has heen exposed <br /> to significant moisture (with a moisture content above 19%)or is curcently wat should be <br /> treated for both a one time surface growth cleaner and treated to limit future growth. A <br /> c�ood surface treatment cleaner should include a 50/50 watedbleach mixture that is <br /> spray or roller applied and will kill surface growth. A second treatment for a lonyer term <br /> mildicide and growth inhibitor should then be applied. A wood preservative treatment <br /> such as the Jasco Green Termin-8 should be generously applied by brush or roller in <br /> accordance with the recommendations of the manufacturer. <br /> Surface Mold & Funpus arowth: Framing members that have not experienced fungal <br /> - decay but exhibit surface mold may remain in.place provided that ihe mold is removed <br /> through chemical treatment. <br /> � Replacement: Framing members that require removal and replacement based on ihe <br /> criteria below shall be replaced with new wood framing that comp�y with the original <br /> construction documents, unless deviations from these documents are specified in the <br /> n�c nrtact with co c ete hall be pressuhe-t eated. See the General Structural N tes d�lor <br /> recommendations on metal fasteners used to connect pressure treated wood. <br /> Special Condiiions: Where questions arise regarding the extent of deterioration or the <br /> mitigation, the structural engineer will make the final determination. For unique <br /> conditions and areas of significant deteriorati�n the structural engineer is to be <br /> contacted to assist in generaling detailed recommendatfons. <br /> ��/�`� <br /> „ <br />
