Engineering geologists may know that the originators of the empirical (a posteriori) Q-system method of rock mass classification for single-shell tunnel and cavern support estimation, were Barton in 1974, and mostly Grimstad in 1993 and again in 2002, due especially to all the tunnel case records collected by Grimstad and his new support diagram for fibre-reinforced shotcrete. Of course, co-authors Lien and Lunde, and especially Løset made helpful contributions at NGI in the early days. Much more recently, younger authors at NGI presented the Q-system with some new opinions in their ‘Q-handbook’ in the period 2013-2015. This was initially funded by the Norwegian Road Authority, SVV. NGI have thereby (in the competitive world of Google) displaced the originators of Q from the immediate search area. Perhaps originators in general should accept this? However, as a result of major project reviews and some court cases in recent years we have to warn of some errors in the NGI ‘Q-handbook’, which contains some unilateral modifications and occasional mistakes, including a strange and dangerous Jw opinion and an adverse cavern height definition error for estimating the reinforcement needs of high walls. An SRF table is also slightly modified. Furthermore, the support chart has been simplified based on a demand from the Norwegian Road Authority. The source of unexpected opinions about applying the Q-system which have recently been read during major project reviews by Barton proved to be the NGI ‘Q-handbook’. Surprisingly, even the reported ‘years’ of development of Q in the first sentences of the ‘Q-handbook’ and therefore in their Google-space are erroneous, signifying lack of interest or of necessary research. So those who have downloaded from the NGI ‘Q-site’ should be aware of such errors. The significantly older originators of the Q-system were not involved, and references to earlier Q-publications are mostly missing, even incorrect. As an alternative, RG pages can be consulted for early multi- and single-author Q-system publications. (1977, 1980, ASTM-1988, 1994, 2002, NFF-23: 2014, 2015, 2017-NMT/NATM). Nick Barton and Eystein Grimstad, 2014 give an in-depth treatment of Q and NMT and provide numerous illustrated examples of Q-logging. The Q-system originated at NGI long ago, but the active developers of this internationally-applied method left NGI one and two decades ago. Research Gate: Nick Ryland Barton, and www.nickbarton.com has all the earlier and more recent Q-literature for free download, so those wishing for in-depth material on Q, single-shell tunnel support recommendations and rock joint behaviour can avoid, if they wish, the Google ‘big-company’ bypass. An interesting thought at the end: do new authors who were in school when a method was developed get to 'own' the method because they have joined the organization where the method was developed 20 or 30 years before, with the originators now practicing elsewhere?
