Enhancing Insurance Risk Assessment: The Protection Class Calculator by GCS and WSRB
The Protection Class Calculator (PCC), developed by GCS for the Washington Survey and Rating Bureau (WSRB), utilizes embedded GIS web service logic and data to deliver highly accurate protection class scores to insurance clients in near real-time.
Problem Statement
In 2003, WSRB approached GCS to design and implement an advanced Protection Class Calculator that features an elegant user interface and utilizes a complex algorithm. The PCC is essential for determining risk for commercial properties and producing scores on a scale from 1 to 10. WSRB sells these calculated PCC scores to leading insurance companies worldwide that underwrite property in Washington State.
WSRB required the development of an automated Service-Oriented Architecture (SOA), integrating Microsoft .NET and Esri ArcGIS technology, alongside custom GCS code. This solution needed to be readily accessible and seamlessly integrated within their insurance risk assessment system.

Innovative Solution
GCS successfully delivered the Protection Class Calculator system, incorporating embedded GIS web service logic and data. This implementation enabled WSRB to provide highly accurate protection class scores to their clients efficiently.
Key Benefits:
- Optimized Workflow: The SOA streamlined WSRB’s operational processes, reducing labor costs.
- Increased Sales: The new system allowed WSRB to sell more protection class scores at a faster rate to their insurance industry customers.
- Long-term Partnership: GCS has maintained a strong working relationship with WSRB over the past decade, leading to multiple upgrades and new versions of the PCC system, while also pursuing additional engagement opportunities with the client.

Conclusion
The Protection Class Calculator exemplifies how GCS leverages cutting-edge technology to enhance the efficiency and accuracy of insurance risk assessments for organizations like WSRB. By integrating GIS capabilities and custom software solutions, GCS continues to support the insurance industry’s evolving needs in Washington State and beyond.
