Many of them had dimensional 2x lumber chris-crossed over the top of <br /> the screw jack to pick up two existing fioor framing members. The new dimensionat lumber was piaced flat, in iYs weak <br /> axis so it would not have signif�cant strength or s#iffness to pick up floor loading in#his con�iguration. This is acceptabie <br /> since the purpose of the screw jacks as placed is to just sligMiy reduce the bouncy feeling of the floor framing rather than <br /> to be a primary verticaf load resisting efement. The base of#he jacics are in direct contact with th�conctete floar slab <br /> and is acceptable, but may cause cracking of the floor slab due to ttre concerrtration of the loads dire�tly over the slab <br /> and not distributed over a farger area of the floor slab. The screw iacks shoutd be monitored bv vou for sians of <br /> iaoseninq,movement etc �nd should be anchored to concrete stab wtth a minimum of a sinale anchorto the <br /> stab and should also be na�led to the wood members at the to of the screw"ack. <br /> ExtErior Gradir�c� T,d"ark; <br /> You did�ot do any significant re-grading of the house site and primarity!ef#the site drainage as it has been for Fnany <br /> years. You did s#ate that you did add in a� exterior drain tile system adjacent to the exterioF of the foundation wall and <br /> have it daylight draining away from the house site. This should be acceptable since he did not do any significant <br /> changes to the site#hat would require re-grading. Any future site work shouJd atterr�t to dive�t surfaee mofSture away <br /> from the house and should consider the use of impervious materiaEs at the surface adjacer�to the house to reduce the <br /> potentiaf of moisturE infittration into the basement area. <br /> Front Porch: <br /> 1.

The condition of the exterior should con#inued to be <br /> monitored by you and shoufd be maintained as required. <br /> Continued on next page,,,,, <br />
