CIVIL/STRUCTURAL ENGINEERING AND PROJECT MANAGEMENT SERVICES Board of Directors January 11, 2022 c/o ATLANTIS ONE CONDOMINIUM ASSOCIATION, INC. 10102 South Ocean Drive Jensen Beach, Florida 34957 Re: Emergency Corner Balcony Shoring 01 and 10 Cantilevered Balconies Atlantis One Condominium Dear Board Members: While conducting our investigation and evaluation of the individual walkways and individual unit balconies, it has become apparent that the 01 and 10 stack cantilevered balcony slabs has sustained significant long-term deterioration, which has resulted in the excess sagging (deflection) of the said balcony slabs. The degree and/or severity of the slab deflection varies from floor to floor, but the observed conditions raise real concerns about the structural integrity of the horizontal structural elements. In addition, severity of degradation of the perimeter aluminum picket railings also is of concern. Based on our evaluation, we therefore are recommending that all of the 01 and 10 unit corner cantilevered balconies be immediately shored to address the observed deflection conditions. The placement and anchorage of the 5K (min.) post shores around the perimeter of the balconies, in accordance with the included drawing, is imperative to provide support for the existing slabs, preventing any further deflection. The anchored post shores can also provide additional lateral support for the existing perimeter balcony railings, further securing the balconies. The post shores will most likely remain in place until the initiation of the pending concrete restoration and remediation project. I have been asked to arrange for a contractor to initiate the immediate implementation and placement of the shoring of the 01 and 10 stack balcony slabs and also to secure the identified loose railings. I have previously worked with DMF Construction, Inc. who is presently working down the street from the Condominium, and fortunately is available to start with the placement of the post shores by midday tomorrow. During the placement of the shoring and securing of the railings, access to the corner stack balconies will be restricted to only the workers. Once all the shoring has been installed, secured and inspected, along with the perimeter railings, the residents will most likely be able to occupy or use the balconies. 4 my office should there be any further questions.
