Here's a 4D building information model (BIM) of the planned new stadium for the LA Rams football team. A 4D model is one that ties objects in a 3D BIM model to activities in a CPM schedule (the 4th "D"). As the schedule is "played" on a computer display, each object in the model appears when it is encountered in the schedule like a time-lapse video. This 4D model, produced by the Conco Companies, a concrete design, construction and formwork supplier, is a good example how 4D works.
The promotional video below shows some simulated flyovers and flythroughs of the project, stated to replace the 93-year old LA Coliseum as the temporary home of the Rams. The Coliseum will continue to be operated and maintained by the University of Southern California (USC) and will take part in a bid by LA for the 2024 Olympics. Visit Los Angeles Curbed for more information on the project.
