Case Study

Automated Regulatory Compliance Check System

■ Clients

・City of Yokosuka

・Toda Corporation

■ Challenges

・When companies involved in urban development or construction submit a building confirmation application (Japan's statutory pre-construction review of building plans) to a local government, they must comply not only with national law but also with the ordinances, rules, and other requirements set by each municipality. Every time a project site changes, this means the laborious task of exhaustively researching the rules that apply in that particular area.

・Differing interpretations of laws and regulations lead to time-consuming back-and-forth.

■ Solution

・A system that automatically determines which rules must be complied with when filing a building confirmation application

・Leverages a large language model (LLM) to provide answers that reflect the ordinances, rules, and other requirements established by each municipality

・When users enter the conditions of a construction project, such as site area, building use, and structure type, the LLM automatically determines, based on those conditions, which ordinances and rules must be complied with at the planned project site
