Cross-Discipline Collaboration with Building Information Modeling Systems

In an industry where time is money and deadlines are imperative, design technology is an extremely valuable asset. For years now A/E/C professionals have been using computer aided drafting (CAD) to save time, improve documentation and increase productivity. In 2005, CAD efficiency has been taken to the next level.

"In 2005 it's all CAD, all 3D," said William A. Berry & Son, Inc. CAD Operator/Engineer Jason Giampa. "Design data can be created faster and more accurately than ever before with 3D CAD software."

Three-dimensional modeling building information modeling (BIM) software such as AutoDesk's Architectural Desktop ® and Building Systems ® packages allows engineers and designers to actually construct an entire building and its systems in virtual reality. Architectural Desktop® is used to help building designers and their clients visualize the project in greater detail than cardboard models. Building Systems® allows spatial conflicts of all kinds, especially those that are normally difficult to identify in 2 dimensions such as conflicts between the various MEP systems, to be more easily identified and resolved on paper during the design process. This prevents costly changes after the project goes to bid or into construction.

A construction manager can be a valuable participant in this process by offering BIM capabilities in-house. The Engineering Department at Berry encourages the use of BIM technology to simplify the coordination process. By using Building Systems®, mechanical coordination can occur before the project is bid, which streamlines the coordination process in the field, saving valuable time and money. The trick is to have building information modeling software that is compatible with what consulting engineers and subcontractors are using. Currently, different businesses are using different technologies, and some smaller firms find the cost of new software and proper training on its use too costly. Using compatible systems enables coordination with the entire design team, from conceptual two dimensional design through to construction documents.

"Over time I think the design community and especially the engineering community will come around to the point where they find it more cost-effective using building information modeling software because it will solve a lot of field problems," said William A. Berry & Son, Inc. Engineering Manager Mark Luchini. "If every job is coordinated on the designer's desk, as opposed to by subcontractors, think about how much time that would save. The six month to one year coordination process would greatly decrease because the entire coordination process would be done up front when it should be."

Although not yet perfectly in synch across the A/E/C industry, BIM use is increasing. Soon it will be common practice for entire projects to be designed using BIM systems. Architects, engineers and construction managers will "create, manage and share design information more effectively, all of which contribute to increased profitability, reduced risk and minimized inefficiencies in building design, construction and management.1"
