Purpose and Objectives Identify, analyze, and evaluate current use of interactive electronic simulation in construction. Objectives Determine and evaluate existing technologies. Develop procedures and recommendations on when, how, and what type of technology to use.

Definitions Electronic simulation includes: Spatial Visualization (3D-Static) – 3D CAD systems and tools Virtual Interactive Environment (3D-Dynamic) – adds ability to manipulate objects

3D Static – Plant Walk Through

Definitions Electronic simulation includes: Spatial Visualization (3D-Static) – 3D CAD systems and tools Virtual Interactive Environment (3D-Dynamic) – adds ability to manipulate objects

3D Dynamic – Crane Lift

Definitions Construction Process Simulation Mathematical models used to simulate system interactions Integrated Simulation Environment The integration of 3D-static, 3D-dynamic, and mathematical simulation models into a unified framework.

Integrated Simulation Environment

Research Method/Approach Three different surveys Two case studies Extensive review of literature and supplier product information Industry conferences and trade shows

Constraints Rapidly changing technology “Snapshot in time”

General Findings 82 percent used 3D CAD systems. 67 percent used Virtual Reality/Visualization tools. 65 percent used these tools to improve project management. Mathematical simulation tools not widely used. Most respondents have made some level of integration and desire more.

Major Uses of Visualization Tools Design interference checks Equipment installation and access Plant layout Maintenance and operations review Constructability review Construction interference checks

Perceived Barriers High capital cost Cost-benefit unclear Lack of information Lack of trained people Resistance to change No champion

Special Considerations Training Hidden Costs Learning curve Administration and customization costs Establishing standards Cultural changes Support group Specialized training for different groups Sharing vs. hoarding of information

Perceived Benefits Constructability benefits Reduction in rework Client satisfaction Improvement in quality Project management benefits

Tool — Decision Aid Emerging Technologies Web site http://www.new-technologies.org/ECT/ Web-enabled database Module 1 – Is ESIC right for you? Module 2 Specify desired applications, features Identify suitable products

Conclusions ESIC is a rapidly evolving technology. Research latest technology for best fit. ESIC adds value (92 percent believe). Significant benefits reduction in costs reduction in schedule reduction in rework Benefits outweigh barriers.

Recommendations Analyze current and future needs. Research current technology. Training! Use the tools. ESIC Implementation Guidelines Supplier Criteria Review Checklist Decision Aid
