The last ITAtech guideline N°12 on services of machinery for mechanized tunnel excavation is available!

The report is to provide guidance for project owners, designers, TBM users, TBM manufacturers and TBM service providers when specifying requirements for TBM services, through the creation of a common language in terms of TBM Services. 

It does not cover TBM refurbishment which in some cases may be considered a TBM Service activity. Guidance for this is given in ITAtech report N°5-V2 "Guidelines on rebuilds of machinery for mechanized tunnel excavation.
