Engineer Reported ‘Major Error’ in Construction of Condo Tower That Collapsed A 2018 engineering report released by the city of Surfside, Florida on Saturday found a “major error” in the construction of the 12-story condominium building that collapsed on Thursday morning, leading to water infiltration that caused structural damage below the pool deck. “The main issue with this building structure is that the entrance drive/pool deck/ planter waterproofing is laid on a flat structure,” says the October 2018 report by Morabito Consultants. “Since the reinforced concrete slab is not sloped to drain, the water sits on the waterproofing until it evaporates. This is a major error in the development of the original contract documents prepared by William M. Friedman & Associates Architects Inc. and Breiterman Jurado & Associates, Consulting Engineers.”
