Overcoming obstacles and transforming an enormous quarry for Atlanta’s Water Supply Program
Recognising the bentonite machine
Paola De Pascali visited John Bartlett following his being awarded the Frank Whittle Medal for the invention of the bentonite tunnelling machine
In sync
The successful logistics of staging four TBMs from one location has enabled the first pair of machines to make a breakthrough near Oslo, ahead of schedule. Nicole Robinson reports on the Follo Line’s first major milestone
Underground electrification
Paola De Pascali attended the “Power Change Days” event in Sweden, organised by Epiroc, to discover one company’s approach to the coming battery revolution
Flood control
Paola De Pascali talked with the technical director of Lombardi, Alessandro Damiani and Pierfrancesco Redaelli engineer of PAC, about the challenges met during the excavation of a water diversion tunnel in Genoa
Tube banks on overhead crane
A major upgrade to one of the world’s oldest deep underground railways, at Bank in London, relies on a single overhead crane nestled in a side street. Positioning the crane, and the logistics of its operation, posed a considerable challenge. Will North reports from the site, and sees how the crane contributes to work below ground.

Sequential excavation method tunnelling
Sequential excavation method (sem) is a type of tunnel design and construction that started to gain popularity in the 1960s and 1970s. The essential component of the SEM approach is to take advantage of the natural capacity and strength of surrounding geology to support the tunnel with minimum cost and time required.
