We <br /> are the certified installation contractor in the area for this product. Additional information <br /> can be found at our distributor's website,www.structuralanchorsupply.com. <br /> Information Given: <br /> • The existing deck at 1050 Willow View Dr., has suffered damage due to frost heave <br /> and/or settlement of the existing footings. This footing movement has created an un-level <br /> deck. We intend to remove and replace the existing footings with helical piers. The deck <br /> will be shored up to allow the removal of the existing posts and footings. Once the <br /> footings are removed and the resulting holes will be backfilled.After backfilling is <br /> complete the helical piers will be installed. The piers will be installed to a minimum <br /> working capacity of 10 kips,which relates to an installation torque of 2,500ft-lbs for the <br /> 2 7/8"round shaft piers. The piers will be installed to a minimum depth of 10' which <br /> corresponds to a minimum of 5' cover over of the top helical flight. Once the helical piers <br /> are installed the deck will be re-leveled and the posts will be installed on the helical piers. <br /> Submittals: <br /> • 2 7/8"Helical Porch Footing Detail - 1 Page <br /> • Chance RS2875.203 Lead Section Detail - 1 Page <br /> • Chance RS2875.203 Extension Detail - 1 Page <br /> Should you have any questions please contact me at your earliest convenience. <br /> Sincerely, <br /> Atlas Foundation Co. <br /> Brian Sanchez,P.E. <br /> Project Manager <br /> nr, <br />
