This is a publication of ITAtech committee of ITA (International Tunnelling and Underground Space Association). It is offered free to download by ITAtech.

Forword of the document says:

"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."

ITAtech describes its aim as "to provide a platform for engineers, manufacturers, contractors and suppliers to draw global experience and expertise together for the benefit of the whole industry, and to find ways of supporting the introduction of new techniques and products by collaborating on the development of design and performance criteria and preparing application of best-practice guidelines".

A very valuable reference document:
