The Role of Underground Space in Future Sustainable Cities


Construction of tunnels and underground structures is growing worldwide. The global yearly market is over 100 bn US$.

Unfortunately, the construction of tunnels and underground structures are seen as very expensive projects, always over cost and difficult to manage by owners.

But with a planned growth of urban population worldwide expected to reach 80%, it is necessary to double the urban infrastructures within the next 3 decades and notably many of them being built underground.

To do so, it is important to have at disposal contractual practices that are on line with the specificities of building underground.

The Open Session at the WTC 2018 in Dubai will address these issues of Contractual Practices for the 21st Century. Towards the end of the year, the FIDIC Emerald Book (Conditions of Contract for Tunnelling and Underground Works), resulting of a joint effort of ITA and FIDIC, will be released.

During the Open Session, Tuesday April 24th, representatives of owners, financing institutions, engineering companies and contractors will share with the audience the good examples of contractual practices as the challenges still ahead.

The Chair of the joint FIDIC / ITA task force on the Emerald Book will present the main aspects of the new Contract Form in view of the publication this winter.

  • BBT/ Brenner
