What is Building Information Modeling?
BIM allows building designers to visualize and modify digital models of possible construction designs while showing any or all of a building’s many components and systems. For instance, if a designer tweaks the roof slope, the software immediately adjusts and displays the entire digital model to reflect the change in all other systems.
The BIM tool can compare multiple design options and optimize a design based on selected parameters. So, for instance, if a client wants to optimize a building's design to enhance daylighting or energy use, BIM can help designers accomplish those goals. BIM can also help designers predict how a building will perform into the future and keep architects in the planning stages for heating, cooling, ventilation, plumbing, electricity, and other system needs rather than handing off those responsibilities. BIM is very conducive to collaborative design and integrated project delivery.
BIM & Sustainable Procurement
From the designer’s perspective, there are some challenges that prevent BIM from being implemented across the board in the construction industry. For example, in some cases it may be unclear as to who owns the intellectual property rights to a collaborative design. Also, BIM presents a competitive playing field problem for companies that cannot afford BIM for their employees to utilize.
There are still many kinks to work out to allow BIM to help design holistically green buildings while also maintaining an even playing field for the building designers. BIM is a powerful design tool that, once all aspects of green construction are implemented into the modeling system, has the potential to revolutionize the green building industry through effective integrated project delivery.
