Information-rich virtual environment (VE) for design review

Abstract:In the A/E/C industry, design review techniques are used to improve design quality, insure compliance with current codes and standards, improve design constructability, and meet project’s goals and owner’s objectives. Design review is a multi-tasking approach; information from various independent sources (e.g. building codes and standards, design specifications, design manuals, etc.) needs to be referenced concurrently while reviewing and coordi-nating plans of various design disciplines. Current common design review methods rely mainly on paper-based checklists and 2D plans to perform the review. Several disadvantages of these manual methods can be identified, including: 1) checklists are generic and reviewers need to identify the guidelines that apply to a given review; 2) checklists are also linear in nature which may force the review to follow a pre-defined top-to-bottom sequence; 3) current methods do not allow for a structured automated approach to capturing and sharing reviewers’ comments and feedback; 4) information may not be retrieved quickly and efficiently within the limited review time frame. This renders the design review process time- and resource-intensive which may force reviewers to sacrifice the thoroughness of their reviews. This paper describes an information-rich virtual environment (VE) framework for design review. The framework util-izes a real-time intelligent algorithm to access needed data and information to perform a design review while viewing the 3D model. The algorithm provides various search and retrieval modes to assist the user in filtering, querying, sort-ing and displaying data and information during the 3D model walkthrough. Reviewer’s comments and changes are cap-tured and shared by others. A proof of concept prototype is being implemented using the Torque 3D Game Engine.
