3D BIM modeling - A Real-Time Foundation for Construction Project Lifecycle

1. 3D BIM modeling - A Real-Time Foundation for Construction Project Lifecycle Building information modeling (BIM), formerly a "contemporary technique" to plan, construct, and manage construction projects, is now becoming "compulsory" for all projects, large and small. Although the standards and expectations vary from project to project, today all public-private partnership (PPP) tenders call for some level of BIM capability and delivery. BIM is essentially a technique for exchanging information, communicating, and collaborating. BIM entails employing a digital model throughout the entire project lifecycle, from the conceptual stage all the way to handover and facilities management. Right now, 7 BIM (dimensions) are used throughout a project's life cycle, but AEC professionals start to recognize them after 3D BIM. Any project that follows the BIM process must start with Revit 3D BIM modeling. The geometric 3D modeling of a project with a high Level of Detail (LOD) and high Level of Information is a part of the 3D BIM stage (LOI). The digital 3D model will serve as the cornerstone of a BIM project if it is implemented properly and will speed up decision-making from the very early concept design stage all the way through the project lifespan, including crucial collision detection during the construction phase, or even before it! What is 3D BIM? A new "Z-axis" is added to the already-existing "X-axis" and "Y-axis" in a shared informative model, or 3D BIM. The most well-known BIM dimension is likely 3D BIM. BIM is defined as the "Use of a shared digital

2. representation of a constructed asset to assist design, construction, and operation processes to establish a solid basis for decisions" by the international standard for BIM, ISO 19650:2019. It is not a process that is added on, nor is it about making a 3D model for its own purpose. BIM is essential to the organization and management of a project. Creating geometrical and non-geometrical information and sharing it in a common data environment is the process of 3D BIM (CDE). As a result, project participants can better manage their multidisciplinary collaboration while modeling and analyzing challenging structural issues. The core of 3D BIM is the development of exchange information requirements (EIR), which outline the data that an employer needs in order to acquire, develop, and manage a built asset. By stating this in a contract document, it is ensured that the right information is produced at the right time in the right format. Building information models at BIM level 2 (the most well-known level in the AEC sector) are likely to include a number of models created by various appointed parties, as well as model files, documents, and structured data files that contain non-geometric information about the building's floors, spaces, systems, and components. Together, they produce a federated digital copy of the constructed asset that starts out representing the original design intent before reflecting what was actually constructed and installed by handover. The 3D modeling is one of BIM's 7 dimensions. The levels of information in each BIM data are described by the following BIM dimensions: • Geometric and graphical data for 3D modeling. • 4D time-related information | Gantt charts and timelines used to sequence construction. • Cost management, building cost estimating, and 5D BIM cost estimation. • 6D sustainability impact studies on the environment, economy, and society. • 7D life cycle and maintenance| Facility management: planning and oversight of upkeep tasks over the course of a building's lifespan. Every dimension depends on 3D geometry to function. The number of dimensions that may be used by all project participants to study or analyze the building in the digital environment, however, is expanded by the amount of data and information that is contained inside the geometry.

Coordination and 3D BIM Modeling

3. The process of 3D coordination, also known as clash detection, combines 3D models from several consultancies, utilizing Autodesk Navisworks. Although Navisworks is not a modeling tool, it can import models from various formats and combine them into a single file known as a "federated model." In this setting, all the various models are compared to see if there are any issues that need to be resolved. Finding the owner of an element that is in conflict with another is simple because 3D model store all the data. BIM in 3D Visualization It is simple to quickly create a 3D massing model of the initial design concept and overlay it onto precise site data using BIM and 3D visualization software. As a result, the clients are given a better understanding of the suggested design and any necessary adjustments can be made before the project has wasted too much time. You can perform inspections and first-person model exploration using the 3D modeling tool Autodesk Revit. Future building tenants and others with no technical background in BIM modeling can explore the model by sharing it in the cloud. The Prospects for 3D BIM Modeling The future of 3D BIM modeling may already be here, as it is now possible to connect collaborative models with psychical on-site structures by fusing intelligent digital 3D models with reality capture technologies. A developing trend in the sector is the integration of 3D BIM with intelligent technologies like artificial intelligence. Big data and intricate algorithms can be used to quickly produce standardized design models (using AI). The viability and cost of the developed digital models, as well as the local environment and the developer's particular requirements, can then be evaluated on virtual platforms like BIM 360 OPs. This enables early decision-making and commitment-making, which accelerates the entire process. Additionally, 3D BIM can be combined with virtual reality (VR) and augmented reality (AR) to provide a uniform method of working with and understanding structures. People from all over the world could visit and experience a home or an entire development from their living room by a VR headset. Homes or entire developments could be hosted in the cloud. These technologies have already been sped up by the COVID-19 epidemic. According to Goldman Sachs, the VR real estate market may be worth £1.99 billion by 2025 and revolutionize how homes are rented out and sold. Final Thought The digitalization of the AEC industry will be centred on 3D BIM modeling. The foundation for a digital twin model is the ultimate goal of 3D BIM. As mentioned, all parties involved in the process, including architects, engineers, surveyors, and owners, will use the ability to develop an intelligent digital 3D model that preserves information for years to come in order to make informed judgments. New technologies are going to open up new possibilities and produce a large return on investment. 3D BIM first needs time to be integrated and assimilated. It's an exciting time for 3D BIM as we transform how
