There was a time when tunnelling formworks were designed and fabricated in jobbing shops close to site. However, with the rock excavation and support process taking less time, installation of the concrete lining becomes a far more significant factor in the cost/time equation. This has led to more sophisticated design of formworks with easier set-up, accurate positioning, and higher mobility. As a result, it is not nowadays unusual to see tunnels with 12 m-long formworks advancing twice each day. To achieve this realm of productivity, specialist manufacturers have emerged, and these are the companies that are powering the process.
