Application of 4-D CAD in the construction workplace

4-D CAD is a powerful tool for construction managers. It is also a tool that can be used at the foreman level. The concept of requiring foreman to equate three-dimensional drawings with time should be the goal of every construction manager. Time is the basis on which contracts are awarded, disputes originate, and the projects success is judged. A foreman must understand the intent and end result of a segment before it can be constructed. If the foreman can be helped through this process with visualization tools, the issue becomes one of cost versus value analysis. Current computer technology is making its way into the hands of foreman through the use of portable computers, PDA's, and wireless communications. The acceptance of computer technology by foreman is on the rise with many companies making it a requirement for employment. This acceptance is what makes 4-D CAD desirable for field application in the construction industry.
