Be Conference 2008 Innovating Substation Design Leveraging 3D Technology

50,000 Foot View Decrease Bill of Material Creation Time Decrease O & M Design Time on new assets Create easily maintainable standards Easily apply standard designs to projects Provide Design Estimates prior to construction Decrease errors in material procurement

The Result Add a module to an existing tool to generate Bills of Materials and provide Design Estimates Integrate directly with MicroStation Provide ability to order materials as a direct result of the 3D Model Watch Demo

Investment & Savings for Intelligent Substation Design Project

Final Projected Savings Design Time - Save 30% = 7426 h/yr BOM Prep Time - Save 60% = 2122 h/yr

SE PORT Objective Overview Improve Substation Project E&C Process The process: Estimate>design>construct>manage –Improve cost, quality, speed –Reduce outside service $ –Apply technology well established in other industries Key process improvements: –Link drawings with material library & cost data –Simplify BOM, procurement process –Improve estimate precision, cost control (link E/D) –Facilitate design optimization –Avoid redundant data entry into multiple tools

Substation Intelligent Design Goals CAD Interface – speed physical design work –Complete project drawings using smart cells –Automatically generate Bills of Materials (BOM) –Automatically calculate material counts –Generate “design complete,” pre-construct estimate –Facilitate design optimization for cost reduction –Request material as assemblies v. components –Explore: reduced # drawings, synch object views

Benefits Already Realized Complete, accurate cell library already available for both 2D and 3D application New Substations built with Intelligence already improving rehab process Standards are easier to maintain due to only having to change the 3D model, then update the sheets

Next Steps Finish 3D CAD Practices to ensure consistent use of Intelligent Design Improve CAD interface to better accommodate design process (Dec 08) Certify users for 3D Design Train users on CAD Interface and Intelligent Design Look for other opportunities to improve our process using available technology!
