Estudio para la Central de Urgencias de la E.S.E Hospital Pedro León Álvarez, de la Mesa Cundinamarca

Abstract

A pathological study was performed on the Emergency Center of the Pedro León Álvarez Díaz de la Mesa Cundimarca Hospital, in order to determine the origin and causes of the visible lesions, define an intervention program and establish preventive measures to ensure the durability of the building. The building consists of one floor, with a slab foundation and sagging beams, structural walls and a thermoacoustic roof with metal trusses. As background, construction began in 2016 (no exact date), and due to economic constraints and design problems, the Departmental Health Secretariat, terminated the construction contract, in May 2018; Leaving the building, exposed to weather and abandonment, which accelerated its deterioration. During the visit, it was performed, visual inspection, photographic record, inventory of injuries, collection of documentary information (architectural and structural plans, technical specifications, soil studies, among others) and proceed to identify damage (cracks, deflections, settlements, moisture, corrosion, carbonation and loss of surface section). In order to evaluate the current structural condition, destructive tests were performed with core extraction, whose resistance results ranged between 46% (brace beam) and 69.6% (footing) with respect to the 3,000 psi of design. 000 psi of design; shims in concrete elements, which showed steels and coatings adjusted to the designs, identifying in addition, 5/8" rods of Mexican origin in accordance with the NTC 2289 standard, according to the test performed (tensile between 605-669 MPa and creep between 432-495 MPa); also, non-destructive tests with sclerometry, with average result of 33 Mpa (4620 p.s.i.) and carbonation with advances of 32 mm in internal walls and 85 mm in the foundation beam. It is concluded that the building presents a regular state of preservation, requiring structural evaluation (NSR-10, chapter A.10.4) and vulnerability analysis according to NSR-10, chapter A.10.5.
