Alternative performance-based seismic design for tunnels in soft soils
For the Mexico City New International Airport, six tunnels structures are being designed for utilities, public road and ground service equipment. The design of these tunnels has been challenging given the very soft soil conditions, heavy airplane and seismic loads. By A.J.T. Luttikholt/C. Sigarán-Loría.
Download publicationInnovative BIM uses to design the new Airport of Mexico City
The design process for the new Airport of Mexico City is challenging due to the extreme soil subsidence, considerable earthquake risks and large unknowns in the hydrological conditions of the site. Several steps were taken to ensure these challenges can be met while adhering to project planning and budget. A major step in overcoming these challenges is the use of Building Information Management (BIM).

Dutch leading role in Chinese mega tunnel
Mid thirties the Maas Tunnel was the first immersed tunnel in Europe. Almost eighty years later, the 'Dutch tunnel' is still an important export product. In Zhuhai (South China) Dutch engineers contribute to the realization of a megaproject. In Het Financieele Dagblad (article in Dutch)
Download publicationImmersed Tunnel: A Viable Option for The Orlovsky Crossing
The Orlovsky crossing in St. Petersburg has been a hot topic over the past years. St. Petersburg faces a constant balancing act between river navigation and road traffic. In the ice-free period, the bridges over the Neva river open nightly for an extended period of time to allow ships to pass, stopping road traffic for several hours... By J. Bergsma/A. Doorduyn
Marine Works Operations and Environmental considerations when building the Fehmarnbelt tunnel

Download publicationTechnical challenges in immersed tunnelling in the North/South Metroline in Amsterdam
The new North/South Metro line in Amsterdam is currently under construction. The 9km line runs from the northern ring road to the southern ring road and passes the historic and very vulnerable city centre. For the part in the city centre special tunnel techniques are applied to limit the impact on both the historic buildings and the disruption on the city life. One special technique that is applied is the immersed tunnel technique. By ir. J.C.W.M. de Wit
