TBM breakthroughs, archaeological tunnelling in Rome and looking forward to World Tunnel Day. Lots to report and the completion of Tunnels and Tunnelling International 's editorial agenda for 2024 so another hectic week at T&T towers.
Our pick of the news highlights below:
SECOND TBM ARRIVES AT VANCOUVER’S OAK-VGH STATION
The second TBM has broken through at the future Oak-VGH Station on Vancouver’s Broadway Subway Project.
TBM Elsie, operated by Broadway Subway Project Corporation, an Acciona Ghella Joint Venture (AGJV), broke through the station’s east wall on Saturday. The first TBM, Phyllis, arrived on October 12.
The two Herrenknecht AG TBMs have each bored 2km of parallel tunnels and together have installed more than 2,600 concrete tunnel-liner rings since departing from Great Northern Way-Emily Carr Station. Phyllis is preparing to launch towards South Granville shortly, while Elsie will follow once scheduled maintenance is complete.

SYDNEY UNIVERSITY LAUNCHES TUNNELLING MAJOR
The University of Technology Sydney (UTS) is launching what it says is Australia’s first major in tunnelling and underground engineering.
Applications are now open to start the course at the School of Civil and Environmental Engineering in February.
The major is aimed at industry professionals and has been designed in consultation with industry experts to ensure students receive real-world and in-field practice as part of the learning experience.Students will undertake projects to develop knowledge and skills to understand new technologies and enhance the design, operation, and optimisation of tunnelling and underground engineering.
WORK PROGRESSES ON ‘ARCHAEO STATION’ IN ROME
Work on Rome’s Piazza Venezia station is progressing, with a hydro-milling machine due to be installed in November.
The station foundations are being installed at a depth of up to 85m. Site work, which has already begun in the central part of the square, will proceed with archaeological core drilling and soil pre-consolidation work, prior to the station diaphragms being installed. Underground utilities along the alignment are being relocated and, once the soils have been pre-treated, the hydro-mill will be installed.
The project has been commissioned by Roma Metropolitane and is being built by the Metro C consortium, led by Webuild and Vianini Lavori S.p.A..
