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

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!
