Virtual design and construction

Virtual Design and Construction (VDC) is the management of integrated multi-disciplinary performance models of design-construction projects, including the product (i.e., facilities), work processes and organization of the design - construction - operation team in order to support explicit and public business objectives.

The theoretical basis of VDC includes:

• Engineering modeling methods: product, organization, process
• Analysis methods - Model-based design: including quantities, schedule, cost, 4D interactions and process risks, these are termed Building Information Modeling (BIM) tools
• Visualization methods
• Business metrics - within Business analytics - and a focus on strategic management
• Economic impact analysis, i.e., models of both the cost and value of capital investments

VDC Managed Project

"Virtual Design and Construction BIMs are virtual because they show computer-based descriptions of the project. The BIM project model emphasizes those aspects of the project that can be designed and managed, i.e., the product (typically a building or plant [and infrastructure]), the organization that will define, design, construct and operate it, and the process that the organization teams will follow, or POP. These models are logically integrated in the sense that they all can access shared data, and if a user highlights or changes an aspect of one, the integrated models can highlight or change the dependent aspects of related models. The models are multi-disciplinary in the sense that they represent the Architect, Engineering, Contractor (AEC) and Owner of the project, as well as relevant sub disciplines. The models are performance models in the sense that they predict some aspects of project performance, track many that are relevant, and can show predicted and measured performance in relationship to stated project performance objectives. Some companies now practice the first steps of BIM modeling, and they consistently find that they improve business performance by doing so." Companies are also now considering developing BIMs is various levels of detail, since depending on the application of BIM, more or less detail is needed, and there is varying modeling effort associated with generating building information models at different levels of detail.
