ITATECH chairman and Atlas Copco vice president Pauli Arenram said that the key focus of the group had been on the production of guidelines, as well as cooperation with other Working Groups.
A number of guides have recently been completed. These include: a guideline on vibration control in urban tunnelling; a guideline for rebuilt TBMs; a guideline for the frequency of measurements in monitoring; and a guideline for fibre reinforced precast concrete.
Several guidelines were declared ready for review, notably including a document on bolting and arch support. An "extensive training package" on lining and waterproofing also requires only a few final changes before it may be published. Arenram who was made interim chair in October 2014 was named full chair to applause after his presentation.
