BRO - Key Register of the Subsurface

FreeOpen Data

TNO / Kadaster

Overview

The BRO is the Dutch key register for subsurface data. It contains geological, geotechnical, and groundwater data essential for construction and development projects. The registration includes borehole data, cone penetration tests (CPT), groundwater monitoring wells, geological and geotechnical models, and soil maps. This data is crucial for assessing foundation requirements, construction costs, and environmental conditions of building sites.

Key Features

  • Borehole and CPT data
  • Groundwater levels and monitoring
  • Geological models
  • Soil contamination records
  • Geotechnical properties
  • REST API access

Use Cases

  • Foundation design and engineering
  • Construction cost estimation
  • Environmental site assessment
  • Geotechnical risk analysis
  • Groundwater management
