I originally met Mr. Larry Coffee onsite November 21, 2008 to view the damages and discuss potential ideas for repair. Mr. Coffee and I discussed the removal of all debris and then reconstruction of the area as a concrete patio versus restoring the original use as a boat launch. The following steps will have to be followed in order for this project to be accomplished: 1. Remove all concrete debris from the damaged boat launch travel surface. The travel surface has been seriously undermined by the wave action on Lake James and I would assume additional pressures that occurred during the flood events experienced during Hurricane season in 2005 and 2006. This material should be removed by barge in order to minimize construction damage to the property and due to the developed nature of the site. 2. Existing Deck slab shall be saw cut as close to the structure as possible to provide a straight joint to adjoin the new deck slab to after construction is complete. 3. A temporary Dike should be erected around the construction site to prevent water intrusion into the construction area. I would recommend a structure such as Porte-Dam due to their excellent performance, however this is can be accomplished by other means. It is critical that the area be diked to prevent intrusion of water into the construction site and to prevent water coming in direct contact with uncured concrete or other construction materials, which may have, potential for contamination of water. 4. Helical Piers shall be installed under the existing house foundation to prevent settling of the structure and support the full weight of the structure to solid ground. 5. The void remaining after Helical Piers are installed shall be filled with Chat stone or sand and compacted to prevent any voids from remaining under the existing floor slab. 6. A concrete footing shall be installed on solid ground on the Lake bottom from inside face to inside face of the existing sidewalls at a distance 5-ft from the house. This footing shall be 16-inches thick with 2 layers of rebar. Each layer shall consist of 3 runs of #4 rebar located 5-inches from the top and bottom surfaces of the footing, with minimum of 3-inches of cover on all sides and ends. One #4 rebar shall be placed every 16-inches OC vertical along the footing tied to the rebar in runs in the footing. Vertical bars shall extend a minimum of 18- inches above the footing surface. 7. A 12-inch block CMU wall shall be constructed to a height 1/2-inch lower than the finished surface of the basement floor, to promote surface water flow away from the home. The wall shall be water tight on each end where it adjoins the existing retaining walls; Mastic or other water seal shall be cast into the end joint to prevent seepage of water behind the wall. 8. One #4 rebar shall be drilled and dowed into the existing wall on each end at 24- inches OC along the height of the wall and 9 gauge ladder reinforcing shall be used in each masonry joint horizontally. This will be to ensure a strong structural tie between the old and new construction materials. 9. One #4 rebar at 16-inches OC shall be dropped into the CMU wall once fully erected. This rebar shall extend from the footing surface to within 3 inches of the top. 10. The 12-inch block CMU wall shall then be pumped full of concrete with minimal vibration to ensure concrete reaches all areas of the walls while not promoting aggregate separation in the concrete. 11. Open area inside the retaining wall shall be filled with sand or chat gravel to within 4-inches of the top of the CMU wall and compacted. 12. Concrete slab 4-inches thick shall be poured allowing 1/2-inch of fall from the finished surface of the basement floor to the top of the CMU retaining wall. Slab shall be separated from the basement floor by an expansion joint cast into the slab with felt material. 13. Entire shoreline along the property with Retaining wall shall be lined with Class B Rip Rap to a height 3 foot up on the retaining wall and 6 foot out from the toe of the retaining wall into the lake to prevent erosion of the shoreline and subsequent undermining of the retaining wall. The shoreline is approximately 82 feet in length. All construction shall be accomplished with ensuring the dike protecting the work site remains erect and sound. Thank you for the opportunity to provide my professional opinion for this repair and modification. Please let me know if my understanding of the project is correct and if this repair/modification is acceptable. Should you have any questions or concerns please do not hesitate contacting me at 828-244-8218. Sincerely, Kevin B.

A temporary Dike should be erected around the construction site to prevent water intrusion into the construction area. I would recommend a structure such as Porte-Dam due to their excellent performance, however this is can be accomplished by other means. It is critical that the area be diked to prevent intrusion of water into the construction site and to prevent water coming in direct contact with uncured concrete or other construction materials, which may have, potential for contamination of water. 4. Helical Piers shall be installed under the existing house foundation to prevent settling of the structure and support the full weight of the structure to solid ground. 5. The void remaining after Helical Piers are installed shall be filled with Chat stone or sand and compacted to prevent any voids from remaining under the existing floor slab. 6. A concrete footing shall be installed on solid ground on the Lake bottom from inside face to inside face of the existing sidewalls at a distance 5-ft from the house. This footing shall be 16-inches thick with 2 layers of rebar. Each layer shall consist of 3 runs of #4 rebar located 5-inches from the top and bottom surfaces of the footing, with minimum of 3-inches of cover on all sides and ends. One #4 rebar shall be placed every 16-inches OC vertical along the footing tied to the rebar in runs in the footing. Vertical bars shall extend a minimum of 18- inches above the footing surface. 7. A 12-inch block CMU wall shall be constructed to a height'/2-inch lower than the finished surface of the basement floor, to promote surface water flow away from the home. The wall shall be water tight on each end where it adjoins the existing retaining walls; Mastic or other water seal shall be cast into the end joint to prevent seepage of water behind the wall. 8. One #4 rebar shall be drilled and dowed into the existing wall on each end at 24- inches OC along the height of the wall and 9 gauge ladder reinforcing shall be used in each masonry joint horizontally. This will be to ensure a strong structural tie between the old and new construction materials. 9. One #4 rebar at 16-inches OC shall be dropped into the CMU wall once fully erected. This rebar shall extend from the footing surface to within 3 inches of the to p. 10. The 12-inch block CMU wall shall then be pumped full of concrete with minimal vibration to ensure concrete reaches all areas of the walls while not promoting aggregate separation in the concrete. 11. Open area inside the retaining wall shall be filled with sand or chat gravel to within 4-inches of the top of the CMU wall and compacted. 12. Concrete slab 4-inches thick shall be poured allowing Y2-inch of fall from the finished surface of the basement floor to the top of the CMU retaining wall. Slab shall be separated from the basement floor by an expansion joint cast into the slab with felt material. 13. Entire shoreline along the property with Retaining wall shall be lined with Class B Rip Rap to a height 3 foot up on the retaining wall and 6 foot out from the toe of the retaining wall into the lake to prevent erosion of the shoreline and subsequent undermining UI L IC retaining wall. The J hor elll IC; Is apps UAII IaLely UL IUUL II I length. All construction shall be accomplished with ensuring the dike protecting the work site remains erect and sound.
