ENGINEERING REPAIR DIRECTION

This Engineering Repair Direction provides for the repair of the damaged wall structuresin full compliance with the requirements of the FLORIDA BUILDING CODE 5thEDTION (2014), including the FLORIDA BUILDING CODE, BUILDING, the FLORIDABUILDING CODE, RESIDENTIAL and the FLORIDA BUILDING CODE, EXISTINGBUILDINGS. The following specific directions are provided for the repair and restorationof the damage identified in the Madice residence located at 1 Festiva at Lionspaw,Daytona Beach, FL (32124). The specific directions are provided relative to the wallsection shown in Attachment "A".

Shoring - Prior to demolition of the damaged portions of the exterior bearingwalls, shoring must be provided to insure that the roof and roof structures areadequately supported during the repair and restoration.

Demolition - Upon removal of the interior wall covering materials from damagedareas of the walls, including the exterior wall, the full extent of the damaged woodstructures will be identified. All of the structurally damaged wood material is to beremoved and replaced. Based on the preliminary evaluation, this may involve theremoval of a number of the 2"X4" wall wood studs including the corner, king andjack studs adjacent to the window opening, the header above the windowopening, sections of the double 2"X4" top plate and portions of the Vz CDXPlywood sheeting. The pressure treated 2"X4" bottom plate is undamaged,however some additional attachment to the existing concrete foundation structuremay be required. The portion of the double 2"X4" top plate, which is found tohave been damaged must be removed in such a manner that the replacementsection of double top plate will be provided with a minimum 16" of overlap splice.

Load Bearing Frame Wall - The schematic load bearing wall structure is shownin Attachment "B". This attachment should be employed in the repair andrestoration of the damaged exterior load bearing wall structure. The requiredstrapping and connectors for the rebuilt and restored bearing walls are identifiedin the attachment with capital letters. These or equivalent connectors must beemployed as shown and are documented as follows:

o A - This is a SIMPSON MSTA24 strap securing both ends of the loadbearing header to the Jack and King studs. The SIMPSON MSTA is to besecured employing 18 —10d nails and provides a tension load capability of1640 pounds.

o B - This is a SIMPSON LSTA9 strap connecting the header to the 2"X6"cripples between the header and the double top plate. The SIMPSONLSTA9 is to be secured employing 8 - 10d nails and provides a tensioncapability of 740 pounds.

o C - This is a SIMPSON SSP stud plate tie, securing the 2"X4" cripplestuds and the full length studs to the double top plate. The SIMPSON SSPconnected to the double top plate is to be secured employing 7 -10d nailsand provides uplift allowable capability of 435 pounds.

o D - This is a SIMPSON SSP stud plate tie, securing the 2"X4" full lengthstuds to the pressure treated bottom plate. The SIMPSON SSP connectedto the bottom plate is to be secured employing 5 -10d nails and providesuplift allowable capability of 455 pounds.

o E - This is a SIMPSON DSP stud plate tie, securing the two King Studs tothe double top plate. The SIMPSON DSP connected to the double topplate is to be secured employing 14 -10d nails and provides upliftallowable capability of 825 pounds.

o F - This is a SIMPSON HTT4 tension tie securing the King and JackStuds to the foundation. The SIMPSON HTT4 is to be secured to the

foundation employing a 5/8" anchor bolt and to the studs employing 18 -16d nails which provide allowable tension load capability of 4235 pounds.

o G - This is a Yz" diameter Anchor Bolt with a 2" washer. This is to be

provided to secure the pressure treated bottom plate to the foundation forall bearing frame walls. The Yz" anchor bolt is to be installed 6" from theend of the wall and all openings and then 24" on center. (This connector isnot required for second floor frame construction)

o H - This is a SIMPSON MTS12 twist strap with 14, 10d X V/z nailssecuring the double top plate to the roof rafters or roof trusses, providingan uplift capability of 1000 pounds.

Double Top Plate - The damaged portions of the 2"X4" double top plate must beremoved such that a minimum of 16" is available for the splice to insure adequatecontinuity for the "continuous" top plate system. The new sections of double top

plate are to be nailed together and to the undamaged portions of the top platewith 12d nails installed a maximum of 3" on center.

Wall Sheathing - The new Yz plywood exterior sheathing material is to besecured to the 2"X4" studs employing 8d ring shank nails, 4" on center along allthe edges and 8" on center in the field of the plywood, however where nailing isnot possible, the studs may be secured to the plywood employing generousamounts of waterproof, exterior grade construction adhesive. The replacementstucco material is to be provided with the required double layer of vapor andmoisture barriers installed over the plywood sheathing and then installed as athree coat stucco system reinforced with galvanized or stainless steel wire meshand secured with galvanized or stainless steel fasteners. The three coat stuccosystem is to provide a minimum thickness of 7/8" of masonry material. Thestucco is to be finished and painted to match the existing stucco materials. Inthose areas where the existing stucco is to be retained over new plywoodsheeting, the stucco is to be secured to the new sheeting with #10 X 2"galvanized or stainless steel wood screws, installed 16" on center horizontallyand vertically.

Window Installation - The existing window is to be reinstalled into the repairedopening and secured with #8 X 3" galvanized or stainless steel screws, 6" fromall corners and then 12" on center on the sides and top to insure that the windowis secured to adequately provide for the +25.5 PSF / -27.6 PSF wind loadpressures.

Interior Wall Finish - Upon completion of the structural repair of the wall,including the installation of minimum R14 insulation, the interior walls are to befinished to match the existing.
