Estudo de caso: aplicação da metodologia BIM em projetos geométricos de vias de baixo tráfego

Abstract

Faced with the need to provide a transport infrastructure capable of meeting population demands, municipal public administrations have resorted to paving the old dirt roads to provide sufficient conditions for the transport of people and goods. Given that these roads generally have a low volume of traffic, an attempt was made to execute a simple project, which does not rule out that the structure may have quality, a prolonged useful life and offer safety and comfort for those who can use the road. Therefore, the adoption of BIM (Building Information Modelling) allows the designer to reconcile the physical and geometric aspects of the road through a parameterized model subject to simulations and tests during the design stage, to give a perspective closer to reality, as well as saving time and avoiding repetition of work or loss of data during the project elaboration process by the responsible team. In this way, the present work presents a proposal for a work routine through the elaboration of a flowchart of decisions to be taken when identifying, through the BIM model elaborated, how to proceed with interventions that provide adequate conditions for the drainage of the pavement, avoiding that its life service is drastically reduced in addition to meeting the minimum safety and comfort parameters proposed by the DNIT (National Department of Transport Infrastructure. Through the development of a geometric design for interventions on a low-traffic road with little infrastructure, it was possible to organize it into three aspects (drainage, comfort and visibility) a logical decision-making sequence for which changes to make in this road, from the attribution of design parameters to the existing road model obtained by the BIM software. The development of the decision-making proposals was possible through of the application of the tools of the BIM computational programs available in a case study of a local road in the seat of the municipality of Aquiraz-CE
