What is 4-D and Building Information Modeling?
The 4-D modeling is a new and innovative technology for contractors, allowing construction schedules to be visualized using 3-D animation, adding the 4th dimension – time. Building Information Modeling (BIM) is the development and use of the computer software model, using the 4 dimensions, to simulate the actual construction and operation of a facility. What are the benefits of BIM? There are many benefits to the owner when incorporating BIM in construction including: u The ability to identify potential problems; u The ability to visualize what is to be built in a simulated environment; u Fewer errors and corrections in the field; u Higher reliability of expected field conditions, allowing for opportunity to do more prefabrication of materials offsite, which is usually a higher quality at a lower cost; u The ability to utilize more “what if” scenarios (i.e. various sequencing options, site logistics, hoisting alternatives, cost, etc.); u The ability for the client to visualize the end
