The emergence of technological tools in construction brought tremendous changes in designing a building. One of the most widely adopted technologies is Building Information Modeling (BIM), enabling a building to design flawless, more effective, cost-efficient, and less time-consuming. BIM is a model-based approach that supports architects, construction professionals, and engineers in their tasks. It ensures optimized planning during construction by minimizing onsite errors and improving coordination among hardware, sub-contractors, and trades.
Generally, architects use BIM software for testing the limits of design in conjunction with structural engineers. It allows a digital solution of ideas and detailed vision that can be shared with contractors and clients for accurate construction at the start of each project. At the same time, contractors use BIM for facilities management and as a Common Data Environment (CDE) that ensures whether the project meets industry specifications and governance before submitting a detailed digital record at the end of the project.
The one major advantage of 4D BIM modeling is that it provides a clear visual representation of the whole construction process through simulations for all the people associated with the construction, including architects, contractors, designers, and owners. Hence, they can observe and analyze the progress of construction activities throughout their lifetime.
4D planning extends 3D visualization capabilities in construction project management to add a fourth dimension of time, sequencing work, and chronological videos explaining projects' execution. It reduces project operational costs by reducing construction time and labor requirements. 4D planning can also be incorporated into project tenders so that customers can have a ready vision of the construction project. A few construction companies are already using 4D planning in their projects. For instance,
Scheduling is becoming a very important aspect of the timely delivery of projects. BIM scheduling is a dynamic process that considers several factors such as location, onsite production plant, flow-line, and communication. There are many advantages of 4D BIM scheduling, including enhanced visualization of the construction process and lifecycle, improved construction planning and management, efficient clash and risk management, enhanced team coordination and collaboration, easy monitoring and tracking of advancement, and better execution of construction process, and cost-efficient.
Key players in the construction industry can adopt 4D BIM in project planning and scheduling, thereby enhancing their tendering and strengthening the project execution to differentiate them from the competitors. With 4D planning, the companies will have an opportunity to explain the project execution with clarity and understanding to their clients and contractors.
