TSSW developed and implemented complex quality-assurance procedures for work completed by the selected Contractor(s) for the street network development. This project demonstrated our ability to work with multiple parties in evaluating and documenting their existing data sets, defining and justifying an E-911 database schema based on our data evaluation, identifying and developing very specific requirements for creation of street networks, Emergency Service Zone and MSAG Community boundaries and integrating all resulting datasets with a comprehensive data quality assurance program.
