The Whakatāne Geotechnical Database and Whakatāne 3D Geological Model have been developed so professional geotechnical and structural engineers can access geotechnical data shared by the Council, other engineers and their clients, and to share their own data in return. This enables engineers to have access to a broader set of test results when considering design parameters and options, thereby increasing the quality and confidence of design and interpretation.
The Whakatāne Geotechnical Database and 3D Geological Model is for the benefit of the whole community. In accessing and downloading data and geological scenes, there is an expectation that engineering users will contribute geotechnical site investigations logs and site investigation reports from work undertaken within the Whakatāne District.
Templates for CPT and drillhole data are provided for engineers to use when undertaking and reporting on geotechnical investigations within the Whakatāne District. The templates prescribe the format the Council requires the data to be submitted in so that the database and model can be easily enriched over time. Queries should be directed to geotech@whakatane.govt.nz
The database and model is also available as an educational resource for schools, and to universities, and scientific institutions to allow them to provide better advice and analysis on geotechnical hazards to all parties, including private enterprise.
Access to the database and model is free to users.
Leapfrog Viewer
Users of the geological model will need to download to free Leapfrog Viewer application. Leapfrog Viewer will run on any Windows PC.

Note: Due to the amount of 3D data in this file, it has an extremely large file size. This file is best downloaded over a fast broadband connection. If you have slower rural broadband or a dial-up connection, you will probably not be able to download this file; contact geotech@whakatane.govt.nz to make alternate arrangements to access this data.
Even if your internet connection's download speed is relatively fast, we still recommend grabbing a cup of coffee or going for a short walk while this file downloads.

Disclaimer
Although the Council’s consultant has used all reasonable efforts to construct a 3D ground model, there is always a level of inherent uncertainty in the results of a model. The 3D ground model does not replace a site investigation or an engineering geological report for a property. Accordingly, the Council, and its consultant accepts no responsibility for any actions taken or reliance placed on the model and its results and excludes liability for any loss, damage, expense or liability resulting from such actions or reliance.
