Computer Integrated Design & Construction (Archived)

This research provides a framework for the identification, justification, and implementation of 3D Modeling in order that many types and sizes of firms can benefit from CII experiences. More effective communication can help participants (owners through constructors) understand better their role in the overall process and how their efforts interact with those of other participants. The 3D Model can, therefore, play a significant role in achieving U.S. construction industry goals related to reducing project costs and improving project schedules. (SD-104, p. 2)

The term 3D modeling, as discussed in this document, refers to the use of computer hardware along with analysis/design packages, databases, and graphics software for a three-dimensional geometric representation of a facility and attributes associated with its design, engineering, construction, and operation. (SD-104, p. 6)

The CII Integrated Design and Construction Task Force have identified where 3D modeling has been applied at the construction site, what successes have been achieved, and what are promising applications. Several examples of application opportunities are listed below: (SD-104, p. 20)

• Engineer/Constructor Design Reviews
• Construction Sequencing
• Safety Assessment

Specialists in different disciplines, e.g., designers and constructors, can examine and view a 3D Model at various levels of abstraction (detail). This helps improve communication and reduce barriers between the upstream (design and engineering) and the downstream (construction) personnel and processes. Specifically the role 3D Models facilitate in better linking the activities among project management, design and engineering, construction, and operation is shown in Figure 2.2 entitled Integrated Design and Construction. (SD-104, p. 10)
