BIM application in Bogota
The implementation of BIM in the Colombian capital has experienced significant benefits and challenges in terms of mobility and urban planning due to its population growth and the need to improve the quality of life for citizens in key projects that allow the planning of transportation infrastructure, traffic analysis, passenger flows, maintenance management and urban transformation for the city.
The Public Transportation System in the city of Bogota faces a series of problems and challenges that affect the mobility and quality of its inhabitants, presenting vehicular congestion, overload in the system, lack of expansion and integration of public transportation systems, maintenance problems, security, high fares and environmental problems. For Egis, an international consulting and specialized engineering services company, its mission is to imagine, create and achieve a sustainable future in all its projects, becoming a strategic partner for the development of Colombia and its capital Bogota, carrying out feasibility studies and planning of transportation and building projects.
For Egis it is important that the adoption of these tools and BIM methodologies are an option when designing their projects, for this reason it is of satisfaction to make a difference when transforming and connecting the city through digital strategies, training of professionals and investment in technology. Egis offers a unique vision and, for this reason, the participation and collaboration in the public and private sector has been a great challenge to ensure a more environmentally friendly city in the following projects:
Bogotá Zipaquirá commuter train, passenger train line:
First railway project carried out with the BIM Methodology by the Egis Colombia team. The technical structuring and feasibility design of the railway line involved an exhaustive evaluation of multiple aspects in the BIM component, from the modeling of the existing conditions of the urban environment within the railway corridor to the urban and architectural design of the stations based on the models. These were some of the key elements in the development of the BIM models:
- Standards and regulations: BIM execution plan, object naming, file coding and level of object information (LOI).
- Data Collection: Survey of existing conditions performed by means of LiDAR Technology that serves as the basis for BIM modeling.
- 3D Visualization: Realization of Federated Model with the different technical specialties of the project.
- Creation of BIM models: 250 models made and more than 260 thousand objects modeled.
- Implementation of a common data environment: Autodesk Construction Cloud as a platform for the management of models, drawings and technical documents of the project.
- Training and management of BIM software: In order to establish good BIM practices, specialists were trained in the correct use of software and BIM standards established in the project.
- Development of urban planning and architecture plans: Based on the BIM models developed in the architecture and urban planning specialty, the technical deliverables and public space planning for each of the 17 stations of the project were delivered on time.
Ministry of National Defense Complex at the National Administrative Center, Bogota:
First building project carried out with the BIM Methodology, a three-dimensional model was made containing geometric information with the objective of identifying the crossings or interferences between the different disciplines involved in the technical designs (architecture, structure, networks), the extraction and quantification of quantities.
The models made in this project were divided into three phases, Basic Scheme Preliminary Project and Project, the objective of each phase achieving benefits for the project such as:
- Preliminary measurements
- Extraction of volumetric information
- Preparation of the actual construction model
- Preliminary construction planning
- Detection of interferences
- Extraction of actual data and dimensions of elements
- Construction and project planning
- Preparation of drawings from the model
The BIM best practices and technical development of the project met the scopes established by the client and the challenge of creating a symbolic building that complies with technical standards, LEED pre-certification, sustainable integrations between a high security building with the urban space, design of a water reuse system, implementation of autonomous vegetation with low water consumption and coordination of a multidisciplinary team.
