Ever since 3D modeling became accessible to the AEC industry, designers and builders have been looking for new ways to provide value via CAD data. Simplistic 3D modeling has evolved to enable preparation of photo-realistic renderings, fly-through simulations, schedule-loaded 4D models, cost-loaded 5D models, and more.

Meanwhile, the concept of building information modeling (BIM) has also gained traction, as designers, builders, and owners recognized the value of associating more than just geometric information with CAD models. By associating part numbers, specifications, and other data with CAD objects, models gained “intelligence.” More recently, the concept of digital twins has been garnering attention, where BIM data are used to build digital replicas of projects, helping owners and construction teams make real-time updates and drive operations and maintenance (O&M) decisions.

To take an industry pulse of BIM/digital twin activity, Cadalyst checked in with designers, contractors, and software firms active in these areas. While widespread adoption is still an elusive goal, firms are making headway in applying BIM and digital twins on a growing number of projects.

Contractors Weigh In

General contractor DPR Construction has been using BIM in various forms for over a decade. Dustin Ridley, DPR’s Arizona virtual design and construction (VDC) leader, has seen the BIM/digital twin concept most successful when implemented early in a project. Early engagement with the owner and design team “provides opportunities to organize and leverage BIM data,” Ridley said.
