HWY A1A – (NORTH BLDG – BLDG. A) – FT. PIERCE, FL 34949 SLC BUILDING PERMIT NUMBER: 2106-0287 PROJECT NAME: Ocean Harbor South Condos – 2021 Balcony Repairs – N. Bldg. / Bldg. A DATE: October 7, 2021 CLIENT: Elliott Merrill Community Management LOCATION: Ft. Pierce, FL CONTRACTOR: Structure-Con PROJECT MGR: Mr. Khris McConnell INSPECTED BY: Mike Lue WEATHER: Sunny WORK INSPECTED: Units 808 & 908 OBSERVATIONS: Unit 808 • The original SGD fasteners penetrated the PT cables under the door track, causing the deterioration. • There are at least (5) corroded and broken cables that require splicing at this area. • The anchor plate of the uniform cable in the north-south direction is located approx. 12” from the slab edge. • The door tracks were recessed, and floor slab is approximately ¾” higher inside of the unit. • Under the door track the required full-depth repairs reach into Unit 708 below. Unit 908 • Approx. 6’ to 8’ of the balcony is visibly lower at the southwest corner. • There are no visual indications of concrete deterioration at this area other than a crack along the slab edge, which will be investigated. • A previous repair has been performed on a larger area of the slab, as evidenced by a pattern change in the stucco on the ceiling. This may not have been formed properly. RECOMMENDATIONS: Unit 808 • We have requested a proposal from a PT testing agency to locate the PT bands and anchors and identify those requiring repair. Depending on their location, these cables and anchors need to be spliced where possible at the west exterior wall or inside the unit. • The broken uniform cable will also require a splice inside the unit, with a new live end at the balcony edge. • The Contractor is to remove the SGD and shoring and provide a weather wall in Unit 708 prior to beginning full depth repairs. Unit 908 • The PT specialist shall locate the uniform PT cable end anchor plate at the balcony edge, confirm that it is under tension, and determine if this could have contributed to the deflection. ______________________________ Michael Lue, P.E.

(1) uniform cable running in the north-south direction is broken. Two sets of bands with (3) cables per band run parallel under south facing SGD. Both the casing and cables of (4) cables have deteriorated due to moisture and penetration from door anchors. Pic 2 Location of bands relative to the door. The (3) cables to the right are directly under the 4” wide door track. M L Engineering Inc.

SLC Building Department Mr. Robert Stark – Structure-Con Mr. Khris McConnell – Structure-Con Page 3 of 3 Pic 3 Anchor plate of broken uniform cable. The anchor plate is located about 12” in from the balcony edge, and it is not a live end. . Pic 4 Note: the interior floor slab is ¾” higher just inside the SGD. When replacing the proposed SGD, the slab should be raised with a structural repair mortar such that the step is outside the door. This will provide an additional ¾” of concrete cover over the cables under the door and ensure a more watertight system.
