Many construction teams face a common question: since BIM is extensively used during the design phase, can we simply rely on the BIM model developed at that stage to guide the construction phase? Is it enough to follow the design directly for construction? The BIM Architecture Training Network raises an important point — can BIM designed during the design phase truly replace BIM used during construction? Let’s take a closer look.
BIM technology plays a crucial role throughout the entire lifecycle of a building, which consists of three main stages: design, construction, and operation & maintenance. Each phase involves specialized BIM applications, often numbering in the dozens or even hundreds. To fully harness BIM’s value across the building’s lifecycle, it’s essential to apply BIM effectively at every stage.
For example, collision detection is a key BIM application widely used during the design phase. However, relying solely on the design phase for collision detection is insufficient. Construction drawings created during design are typically not detailed enough for on-site needs. The construction team must further refine the design, account for construction tolerances, and plan construction methods. Not all collisions can be resolved during the design phase — this requires continuous refinement throughout construction.
Moreover, the construction phase introduces even more specialized BIM applications. Over the next three to five years, hundreds of new applications will emerge, playing vital roles in tracking construction progress, enhancing quality and safety management, and reducing costs.
One common misconception among property owners is a lack of understanding of BIM methodologies, leading to poor implementation and underwhelming results. Attempting to build everything from scratch using a single BIM software and one BIM technology team is unrealistic and unscientific. No single BIM software can cover the vast range of applications needed across all three stages, nor can one team master the professional expertise required for hundreds of BIM applications spanning design, construction, and operation.
The practical approach to applying BIM throughout the entire project is to select appropriate BIM software platforms tailored for each stage, hire specialized BIM teams for design and construction phases, and establish data standards to ensure seamless data exchange between upstream and downstream processes.
So, can BIM used for design replace BIM used for construction? The answer is a definitive no. Both the software and hardware requirements differ and cannot be substituted.
