The NFF website presents publications, reports and other valuable material for high quality underground construction practices and cost efficiency.
NFF - The Norwegian Tunnelling Society has gathered publications and reports which every tunnelling enthusiast would enjoy reading. The contributors are among others, research institutions, consultants and of course, The Norwegian Tunnelling Society itself. NFF does hope that the website may contribute to further knowledge and development of underground technology.
The various contributors hold the exclusive rights for the published material on this website. The editors have requested accuracy, references and proven facts.
NFF
NFF - The Norwegian Tunnelling Society has felt an obligation to share with friends and colleagues what has been learnt during the years. Based on a wide range of observations from completed projects, www.tunnel.no provides technical solutions, projections of wear and tear, predictions of progress, and financial estimates.

NGI Publications
The Norwegian Geotechnical Institute NGI has developed the Q-method since the 1970s. The Q-method is a numerical description of the rock mass quality with respect to tunnel stability. The Q-value is defined by a function consisting of six parameters which may be estimated either from geological mapping or from in situ measurements and from drill cores. The Q-method is used internationally for general description of rock mass quality, and as a guide for estimating tunnel support requirements.
