When producing Volume 1 of this guidance document the authors decided to initially focus on
the design aspects of fibre reinforced concrete segmental tunnel linings, recognising that both
segment design and production constitute equally important aspects for the success of tunnels
lined with precast fibre reinforced concrete segments. Volume 2 therefore concentrates on the
production of segments and the associated quality control.
The advantages of using Fibre Reinforced Concrete for segments are particularly eminent in the
production phase, as the absence or reduction of bar reinforcement typically results in program
and cost savings, and in the reduction of risk associated with the manufacture and installation of
As in Volume 1, the aim of this document is to present the common understanding of designers,
manufacturers and users of fibre reinforced concrete segments of what constitutes good
practice in this field of engineering. The document should be read in combination with Volume 1,
which contains useful information on elementary properties of fibre reinforced concrete.
ITAtech and the sub activity group welcomes all feedback on this document and will incorporate
the user experience with the document in the course of future new editions.
