(min.). - Where 2x P.T. bucks amused for window or door installations, the bucks must be fastened with a 1/4' % 342rr =V TAPCON ® 12' O.C. staggered (min.). 13. RECOMMENDATIONS - The engineer assumes no responsibility for structural damage due to failure of windowe or door or glass breakage. N is recommended that a storm panel system or Impact resistant glazing system be Installed to reduce the chance of major damage due to flying debris. The engineer assumes no responsibility for settling cracks which may develop In a monolithic concrete slab system. The use of a FIBERMESH type concrete additive will greatly reduce the risk of slab cracks due to settlement and temperature changes. The me of diagonal steel at Interior comers of concrete slabs is recommended but not required.
