The Thames Tideway Tunnel is an under-construction 25km tunnel running mostly under the tidal section of the River Thames through central London. It will provide capture, storage and conveyance of almost all combined raw sewage and rainwater that currently overflow into the river. Once constructed, the main tunnel will have an internal diameter of 7.2m and will run from -30m at Acton, West London for over 25km under central London down to -70m at Abbey Mills in the East. It will connect 34 of the most polluting combined sewer overflows (CSOs), via transfer tunnels. The tunnel will transfer the captured sewage to the Stratford to East Ham part for onward delivery to Beckton Sewage Treatment Works.

Luck Stone Corporation (LSC) is the nation's largest family owned and operated producer of crushed stone, sand and gravel. At their plant in Leesburg, Virginia, Luck Stone Corporation acquired a new quarry, which is located to the West of Goose Creek river. An inter-quarry tunnel was constructed to link the existing South-Eastern pit with the new West pit. The tunnel's cross section is approximately 45 feet in diameter, and the tunnel's length is approximately 1275 feet. The tunnel crosses the Goose Creek river approximately 50 feet beneath. The excavation method was drill and blast in hard rock (diabase).

Luck Stone Corporation (LSC) planned to open a new quarry on the Western side of Goose Creek river, a component of the Virginia Scenic Rivers System. A tunnel was envisioned to connect the new Western quarry with the existing South-Eastern one below the river. The rock cover between the tunnel and the river was approximately 50 feet. The tunnel is 1275 feet long with a diameter of 45 feet. It is designed to accommodate large scale mining trucks as well as a conveyor belt for material transport which is scheduled to be installed in the future.

Beacon Hill Station is part of the 22.5 km initial segment of Sound Transit's Central Link Light Rail. It is located 49 m below the ground surface in complex glacial soils with multiple groundwater horizons. The project comprises deep mined station tunnels and two 1.5 km long running tunnels excavated using a tunnel boring machine. The mined station was excavated through compressible glacial soils with multiple groundwater horizons using conventional mining techniques. The access shafts and station headhouses were constructed using slurry walls and cut-and-cover techniques.

The Dublin Port Tunnel is an approximately 3.5 mile long twin, two-lane tunnel which connects the M50 motorway and Dublin Airport with Dublin Harbour. The underground connection will help to manage the rising traffic demands and will carry up to 20,000 vehicles per day upon opening. The overall scheme consists of 2.8 miles of tunnels, where 1.3 miles are Cut-and-Cover and the remaining 1.5 miles are TBM bored 35ft.
