Digitization has come to construction. Short for virtual design and construction/building information modeling, this technology lets you construct a building virtually—on the computer— before any ground is broken. Similar to a dress rehearsal for a performance on Broadway, building things is a concert of complex activities that require analysis and synchronization to achieve the best result possible. All the info on stakeholder needs, and systems (HVAC, plumbing, electrical, etc.), materials, and sometimes their costs, is built in. When you change, say, the position of a wall, the software automatically changes the associated plans, sections, and elevations. The result: better, faster, and more useful buildings.
Seen in three dimensions, 3D Models and BIM allow the building team to break down a complex project, phase it efficiently, and discover the most efficient, innovative way to proceed. 3D models make it easier to perform constructibility reviews, tracking, fabrication, community outreach, and many other construction tasks.
