Challenges, opportunities
26 June, 2023
Groundwater is never an insignificant part of the challenge of determining what is below the ground surface. It can be present in so many, often puzzling, ways and brings potential for difficulties. Consequently, examinations and what information can be obtained from such investigations carried out, ideally early on, will help to inform approaches for dewatering to counter – or might be needed to solve – construction challenges.

Weighty works
15 May, 2023
In this issue, the challenge of gauging what ground conditions most likely exist is examined in a paper based on research, tested in the field, that combines employs geostatistics to sampled borehole data to generate probabilities, especially of transitions in soil profiles.

A sense of time

21 November, 2022
With so much up the air, it seems, as costs and economics bust out of their cages and politicians take to deciding what to do, for the best, recently some noises came to be made about cutting construction projects.

Exchanges and views

Come autumn, come the season of meetings and gatherings and intimate conversations, in huddles as days shorten and darker evenings return, and openly at large events that draw interest from across the industry.

Space below, time above
26 September, 2022
Most often, the focus of discussion surrounding projects can be about how tunnelling is being done or could have been executed. Attention is paid to process details, to design but most of all to the many choices for construction, and then the details of equipment and materials, and logistics and cost, and minimising risk while overcoming what surprises the ground may reveal as tunnels advance.

Seeking sustainability
30 August, 2022
With the global industry gathering in Copenhagen for the first in-person World Tunnel Congress for a few years, much more focus is on sustainability in the creation and long-term use of underground space.
