Welcome to the ACUUS website

We live in an urban world. More than half of our planet’s population resides in cities and this trend will get stronger in the future. Urban areas around the world face difficult and ever growing problems that deteriorate their environmental quality and threaten their sustainability. ACUUS’s core philosophy promotes the systematic utilization of the urban underground space as the most efficient and environmental friendly solution in order to enhance the quality of life and boost competiveness of modern cities.

For more than 30 years ACUUS has been a key player in underground development internationally. The multi-disciplinary character of ACUUS has enabled it to act as an international “think tank” in urban underground development. The MoU with the City of St. Petersburg, the City of Shanghai (SMEDI) and with the UN-Habitat, for which we are very proud, serve as proof for our commitment and efforts in this field.

You can visit ACUUS website and find further information about our activities and our people. Moreover, the proceedings of our conferences, a very important asset of ACUUS, are available for our members. Our weekly newsletter service provides up-to-date information to our members regarding major underground projects, innovative solutions and advances in the field.

I invite you to join the experts of the urban underground space and become an ACUUS member.
