Estudio Patológico de una plataforma de parqueaderos en un conjunto residencial en Bogotá

Abstract

This report presents the pathological analysis of the parking platform at the JJ Vargas Residential Complex, part of which was closed by IDIGER due to structural risk compromising residents’ safety. The platform consists of 0.20 m reinforced concrete retaining walls, a 0.35 m waffle slab with guadua voids, and a 0.10 m topping slab. The methodology included visual inspections with photographic records, review of technical background and previous geotechnical studies, and comparison of findings with the Colombian Building Code (NSR-10). In addition, destructive and non-destructive tests were considered to assess mechanical properties, concrete homogeneity, and reinforcement conditions. Results showed that the main pathologies derive from differential settlement caused by low soil bearing capacity, leading to slab fractures (inclinations of 4° in the upper and 11° in the lower slab), cracking and disconnection of retaining walls, and water infiltration that compromises reinforcement durability. These findings highlight the need for structural intervention, including deep foundations (piles and micropiles), slab and retaining wall strengthening, and reconstruction of non-structural masonry walls, complemented with waterproofing and seismic isolation techniques.
