Chloride Limits for Concrete as required by ACI 318 Building Code for Structural Concrete VII. CONCLUSIONS The structure elements of the building do not comply the current code. (ACI -530; ASTM C56 & FBC 2020). Based on our inspection, we conclude that the walls are composed of clay masonry units and the cells of these units are empty, without grout and therefore are unreinforced.. All the lintel concrete beams inspected present critical linear cracks, corroding the rebar. Grade beams contain critical damage such as spalling and severe cracking, that might compromise integrity of the structure. Based on our inspection, and the damage and the circumstances described above, it is our professional opinion that the current structure has the potential risk of failure in case of a hurricane or heavy storm scenario. VIII. RECOMMENDATIONS Based on the site observations, the conditions of the structural members of the building and level III alteration required by the Florida Building Code, the structural members of this building need to undergo extensive rehabilitation, including CMU reinforcement, lateral systems construction, and strengthening of the foundations. Moreover, repairs to the roof and spalled concrete have to be done. The required foundations augmentation might compromise the total stability and integrity of the house. In order to raise the structure, scaffolding and temporary framing will be installed under the foundation to jack up the structure. The foundation of the house is weak enough to crumble under such loads during the jacking process, due to the footer being on shallow 10 Page 28 of 98 39 Maximum water soluble chloride ion Max Min f, content in concrete, percent by weight w/cm Exposure Class of cement" Reinforced Prestressed Concrete Concrete CO — Concrete dry or protected N/A 2500 1.00 0.06 from moisture C1- Concrete exposed to moisture but not to external N/A 2500 0.30 0.06 sources of chlorides C2 - Concrete exposed to moisture and an external 0.40 5000 0.15 0.06 source of chlorides Chloride Limits for Concrete as required by ACI 318 Building Code for Structural Concrete VII.
