Executive Summary
Engineering consultancy Beca has upgraded the New Zealand Geotechnical Database (NZGD) by migrating it to its BEYON digital twin platform, hosted on Microsoft Azure. The new system features an AI assistant, developed using Azure OpenAI Service, that allows engineers and geologists to query complex sub-surface data using natural language. This initiative aims to centralize critical national data, originally compiled after the 2011 Christchurch earthquake, to enable faster, safer, and more resilient construction and infrastructure development across the country.
Key Takeaways
* Product/Service: The upgraded New Zealand Geotechnical Database (NZGD) is now hosted on Beca's digital twin platform, BEYON.
* Core Technology: The platform runs on Microsoft Azure and incorporates an AI assistant powered by OpenAI's GPT-5.1, developed using the Azure OpenAI Service and Microsoft Foundry.
* Primary Capability: Users can now use natural language prompts to search, filter, and extract crucial geotechnical data, such as soil composition and rock layers, from the national database.
* Stated Benefit: The AI assistant is estimated to reduce the time engineers spend retrieving data by an average of 40%, improving responsiveness and decision-making.
* Target Audience: The primary users are engineering geologists and geotechnical engineers involved in construction and infrastructure projects in New Zealand.
* Availability: The updated NZGD platform launched in November 2024, with the AI assistant layer added in late 2025.
Strategic Importance
This upgrade transforms a critical national dataset into an interactive, intelligent asset, demonstrating the practical application of digital twin and generative AI technologies to solve real-world engineering challenges. For New Zealand, it represents a significant step toward more data-driven, resilient, and efficient infrastructure development.
