Detail of the Geometric Information for the Levels of Information in the 3D Model (LOD) for Urban Road Infrastructure Projects in Bogotá, D.C.

Abstract

Currently, the Building Information Modeling (BIM) methodology has gained special relevance in the infrastructure sector, to the point that various government entities have chosen to develop work plans to achieve BIM objectives, with the aim of optimizing construction and design processes. This is relatively new in the capital district, leading the Urban Development Institute (IDU) to take relevant actions since 2020. However, in the process of incorporating the requirements that different projects must meet, some aspects still need to be defined, such as the geometric levels of information (LOD) for each of the entities that are part of the components in different phases of the project. The IDU documents establish specific lods for each project phase but not for each geometric entity. Therefore, this article identifies the products developed for each design phase of a project based on the IDU Project Maturation Guide and correlates them with the lod established by the BIM Contract Annex V.5. It concludes that it is necessary to separate design components by entities since each of these corresponds to a different LOD, even for the same design phase.
