The traditional design process often lacks direct communication channels between various technical professionals. Design changes are typically made through periodic meetings or phone calls, which can lead to overlapping efforts and create confusion between different disciplines. BIM Technology transforms this workflow by enhancing architects’ planning and design processes, improving both quality and efficiency, and significantly reducing design costs and time.
But do technicians who learn BIM truly know how to apply it? I would like to share my perspective on how technical personnel utilize BIM during the planning and construction phases.
During the planning and design stage, technicians using BIM technology must consider multiple factors such as the owner’s requirements, urban planning regulations, building codes, climate and regional data, cadastral maps, and drilling or foundation investigation reports. This data is then applied to architectural design and interior layouts, on-site surveys, regulatory compliance checks, sunlight and daylight analysis, and environmental impact assessments.
From this, they generate outputs such as 3D models, 2D floor plans (including elevations and sections), energy analysis reports, building coverage studies, plot ratio analyses, and foundation layout drawings. These deliverables assist architects throughout the design and planning process. Utilizing BIM’s spatial information models encourages architects to rethink their design approach by visualizing concepts directly, making the workflow more intuitive for designers.
By representing designs as 3D models, all detailed content can be concretely displayed, eliminating the ambiguities often caused by traditional 2D drawings, especially for complex geometries that are difficult to accurately portray on flat plans. These 3D information models help clarify design details and reduce potential disputes between parties during construction.
In the construction phase, technicians use BIM to perform 3D spatial clash detection, identifying conflicts between structural elements and system pipelines early on. This reduces costly design changes and delays during construction. Adding a timeline to the 3D model allows for 4D construction scheduling and simulation, enabling the formulation of optimal construction plans and better tracking of project progress and quality.
BIM also supports owners by providing reference projects for property management and vendor coordination, ultimately leading to cost savings and improved profitability. For material estimation, BIM can generate detailed reports on materials and components for 5D cost estimation. This assists architects in monitoring whether construction and supplier funding requests exceed the budget during site supervision, helping to prevent material overordering and cost overruns. It also facilitates final cost settlements and offers feedback to all stakeholders regarding design changes or additions, serving as a foundation for comprehensive planning, design, and construction review after project completion.
So, what exactly do technical personnel use BIM for during the planning and construction phases? This brief analysis aims to highlight that simply learning BIM technology and mastering certain concepts does not guarantee effective application. The editor continues to explore this evolving field. Since BIM’s concept extends far beyond its basic definition, it requires a calm and steady approach to identify our shortcomings and continuously enhance our capabilities.
