Sub-Urban Planning and Management Week – Bucharest 13 - 16 March 2017   The ITACUS Chair Han Admiraal was invited to take part in the final conference of COST SubUrban. This EU funded COST Action Network consists of cities and geological surveys from across Europe. Their main objective, to unlock the secrets of the subsurface and make planners and decision makers aware of the limitations and the opportunities the subsurface has to offer to cities. Sound familiar, well it should because this is what ITACUS is aiming for as well.    The COST SubUrban website contains a wealth of information, including planning methodologies. To make all the data available in a different way, a toolbox was developed that is now available to everyone online. The toolbox even includes references to ITACUS and our products.   Why not visit the toolbox and see how the information there can be of use to your everyday underground space work. The toolbox can be found here.
