Prepared by Calvin Kam © 2001 Conventional Practices Means:mail, faxes, Data types:2D information Data standard:non-interoperable Project Organization Information Sharing Decision SupportProject Collaboration HUT-600 Pilot Project Means:project databank Data types:product model Data standard:IFC-interoperable BENEFITS Less information re-entry Less information re-entry Better risk management Better risk management Higher reliability Higher reliability More time to conduct more valuable work e.g. alternatives, analyses More time to conduct more valuable work e.g. alternatives, analyses

Prepared by Calvin Kam © 2001 Conventional Practices Minimal use of visualization, simulation, or alternative proposals due to lack of time, tools, and data. Project OrganizationInformation Sharing Decision Support Project Collaboration HUT-600 Pilot Project An array of tools and software supports decision among 3 design and 2 building system alternatives all performed within a tight design schedule. BENEFITS Owners, tenants, and end-users are better presented with more simulation analyses and alternatives Owners, tenants, and end-users are better presented with more simulation analyses and alternatives Focuses on performance, life-cycle cost, environmental impacts, etc. Focuses on performance, life-cycle cost, environmental impacts, etc.

Prepared by Calvin Kam © 2001 Conventional Practices Project team may spend crucial time describing project issues during meetings and work independently afterwards. Project OrganizationInformation SharingDecision Support Project Collaboration HUT-600 Pilot Project Project team can all focus on issues with real-time product model and come up with interdisciplinary solutions right in the meetings. BENEFITS Ensures all participants are on the same page Ensures all participants are on the same page Improves interdisciplinary coordination Improves interdisciplinary coordination
