This document proposes an economical and efficient approach to electrical survey data collection and network topology creation using GIS survey tools and network analysis software. Key offerings include tools for GIS surveying, data conversion from surveys to network analysis, network analysis services, and diagram/BOQ generation. The approach is estimated to save 35-60 man-days per 100-feeder project compared to conventional methods. Deliverables would include network models, analysis reports, diagrams, and bills of quantities.
