AEC Market Growth Due to BIM, CAD

Construction of a building requires efficient collaboration and information sharing between project members. Traditionally, this was done with paper drawings and documents, but new requirements such as 2D or 3D CAD (computer-aided design) and facilities-management drawings increased the adoption of BIM (building information modeling) for effective information sharing. The global AEC (architectural, engineering, and construction) market will mature at a CAGR (compound annual growth rate) of 11.8% during the period 2017 until 2021.

In 2015 BIM was adopted by architects and engineers for the Diamond Island project in Vietnam. BTA is a key player in Vietnam's infrastructure and construction industry, and it adopted Autodesk BIM software for building the project. The adoption of Autodesk BIM software reduced around 25% of project infrastructure cost related to design changes, reworks, change in orders, and request for information.

Construction projects undertaken through 3D BIM do not provide a platform for the integration of time and cost factor. This has led to the emergence of 5D BIM, which takes more dimensions into consideration. 5D BIM can be considered as an evolution of 4D and 3D BIM.

With project members using different tools for data collection, design, and analysis, interoperability has become a challenge for software vendors in the market. The lack of interoperability makes information sharing difficult because differences in format make the construction process prone to errors.

Open BIM solves interoperability issues by ensuring file, syntax, visualization, and semantic-level interoperability. The adoption of open BIM is relatively moderate in the current market situation. The AEC market will profit from the adoption of the technological solutions and drive the construction market into the future.
