75 The Macro Problem

76 Virtual Design and Construction Case Study Case Overview Baseline Delay Acceleration Summary and Analysis

77 to be the worlds premier academic research center for Virtual Design and Construction Virtual Design and Construction: develop and test new ways to model, visualize, analyze and evaluate the multi- disciplinary performance of design– construction projects to support explicit business objectives Education: increase awareness of the value and costs of strategic IT for practitioners and Stanford students CIFE Mission

78 Need: macro and micro problems require timely stakeholder involvement Tools available, effective, affordable –iRoom, 4D, organization, TEI, … Objectives and metrics exist –Management theory –Manufacturing Actions: 1.Plan your VDC implementation strategy 2.Become CIFE member; plan pilot Call to Action for VDC

79 Virtual Design and Construction Case Study Case Overview Baseline Delay Acceleration Summary and Analysis

80 Build project model early, before committing large money or time What –Product, process, organization How: –Detailed: to show the product, process, organization entities that use significant project time, money –Virtual: in the computer –Visual: multi-discipline, multi-view, for multiple stakeholders –Objective-based: set and track explicit public objectives VDC Big Ideas

81 Need: macro and micro problems require timely stakeholder involvement Tools available, effective, affordable –iRoom, 4D, organization, TEI, … Objectives and metrics exist –Management theory –Manufacturing Actions: 1.Plan your VDC implementation strategy 2.Become CIFE member; plan pilot Call to Action for VDC
