Briefing: Safety innovations in materials testing for tunnel construction

It is accepted that tunnel environments present high levels of risk associated with the confined nature of this type of project, especially during the construction phase. Therefore, it is essential that high-quality product and workmanship are maintained at all stages. In order to achieve this, only the most suitable materials and highly skilled personnel should be used. One area often overlooked or addressed as an afterthought is the inspection and testing regimes of the materials in both temporary and permanent states. By operating a high level of control through adopting best-practice test methods and timely reporting systems, it is possible to better manage risk to operatives and provide surety for the long-term performance required for these expensive infrastructure projects. The identification and implementation of best practice and innovative test methods, together with the short- and long-term benefits of extensive research undertaken are covered by this briefing paper.
