According to Rich Humphrey, VP for Construction at Bentley Systems, 4D BIM is at a tipping point. It’s still not an everyday practice, but is becoming so, and most major construction companies have a virtual design and construction department where BIM is often started in offices. He says that organisations are now not just using 4D BIM during the planning stage but taking that multi-dimensional model through to the construction and execution phase.
Retrofit for existing buildings
The majority of the existing buildings are not maintained and refurbished with BIM technologies, yet the benefits of efficient resource management and rapid developments in technology are having an impact on operators. Parts of the project can be remodelled and realty capture can be used to capture the existing conditions and optimise the design and construction process with respect to time. Moreover, 4D BIM can also evaluate how to safely isolate the work-site and allow engineers and contractors to control their projects effectively and ensure that timelines are met.
