Publication 31: Norwegian Rock Bolting

The Norwegian Tunnelling Society (NFF) is an open society for people and enterprises associated with or interested in Norwegian rock technology. A key aspect of the society’s work concerns development projects for the benefit of the industry. This takes place in close cooperation with relevant actors, and the results achieved are disseminated through NFF’s publications, handbooks and technical reports.
This publication has a relatively long history. In 1973, Kontor for Fjellsprengningsteknikk KFF published a practical handbook on rock bolting (Praktisk håndbok i fjellbolting). This became a starting point for the Norwegian Public Roads Administration’s Publication No. 72 Rock bolting from the road laboratory (Fjellbolting from veglaboratoriet), which was published in 1994, and the Norwegian Public Roads Administration’s handbook V224 Rock bolting (Fjellbolting), published in 2000 (previously handbook 215). A relatively extensive revision was carried out by the Directorate of Public Roads, before the entire process was handed over to NFF in 2017. NFF’s development committee subsequently set up a group which has ensured that it has now been updated to reflect current practice and products.

The work on the revised edition was carried out by:
Marcus Fritzøe Lawton, Bane NOR
Ragnhild Rostad, Veidekke
Thorvald Wetlesen Sr, Bever Control
Anette Wold Magnussen, Norwegian Public Roads Administration
Tone Nakstad, NFF

The drawings in the handbook were prepared by Mette Bergan, Kristine Ekseth and Arild Walberg Solerød.

NFF’s development committee was responsible for proofreading and quality assurance of the work. NFF’s International committee wanted to share this work with the international community, and is responsible for the translation.

Publication 30: Sustainability in Norwegian Tunnelling

NFF has the tradition to present an English publication every year. This year’s publication is devoted to sustainability in Norwegian tunnelling.

The publication is targeted towards both an international and national audience, – both industry members, politicians and the readers interested in sustainability in general. We hope the reader will be inspired to participate in the work for improved sustainability in the tunnelling industry across the world, and hopefully help us to find even better solutions than described in this publication. We truly believe that UN Sustainability goal #17 “Partnerships for the goals” is essential to reach a more sustainable way to work and live.

The publication is written as a joint effort among the scientists, clients, contractors, consultants, and suppliers in the Norwegian tunnelling industry. It contains of a mix of professional papers and strategies shared from our member companies. We appreciate the willingness to share experience and thoughts through this written material.

Publication 29: Tunnelling in the Follo Line project

NFF has the tradition to present an English publication every year. In these publications we focus on different topics we think are relevant to share with our international friends and colleagues around the world. The publications are mostly written as a shared effort across the Norwegian tunnelling industry. This is not the case in 2021.

The Follo Line Project is by far the largest investment made in Norwegian onshore infrastructure as of now. The project consists of two parallel 20 km long urban railway tunnels among other constructions. Being such a special project in most regards, NFF decided that the 2021 publication should be dedicated exclusively to The Follo Line Project.

The publication is written as a joint effort among the client, contractors and consultants involved in the project. As such, the publication does not necessarily represent NFF’s position within the various academic topics. We do, however, believe it is of great benefit of the industry to share the experiences from this unique project.

Publication 28: Digitalisation in Norwegian Tunnelling

This publication describes the status of the Norwegian underground industry and emphasises the utilisation of emerging technologies and BIM (Building Information Modelling) with a practical approach. Disciplines as geology, machine operations, Measurement While Drilling (MWD) data utilisation, rock bolting, technical installations and environmental monitoring are included and discussed in the first section of the publication.

The tunnel clients have been nominated as the main contributors to standardisation and future development of digital processes. By including a chapter for three of the main clients for tunnelling projects in Norway, the publication also provides a wider perspective with regards to future visions and development within the industry. In conclusion, successful implementations of digital processes are highlighted in terms of case-studies.

Publication 27: Safety in Norwegian Drill and Blast Tunnelling

The publication Safety in Norwegian Drill and Blast Tunnelling is intended to be a resource and a guide to promote safe operations from planning stage to completed project.

The publication consists of two parts:

Part 1 (chapters 4 – 6), which primarily addresses clients, designers, coordinators etc.

Part 2 (chapters 7 – 9), which describes “best practice” and is aimed at employers, foremen and tunnel construction workers.

Publication 26: The principles of Norwegian tunnelling

The Norwegian Tunnelling Society NFF is publishing this issue No. 26 in the English Language series for the purpose of sharing with international colleagues, and friends, the experiences of tunnel and cavern construction along with examples of underground use.

The purpose of Publication No. 26 is to demonstrate the content of Norwegian tunnelling by clarifying the principles of this approach, show-case breakthrough technologies and describe various ways of utilising the underground. We have named the publication ‘The Principles of Norwegian Tunnelling’.

Publication 25: Norwegian Rock Caverns

The present publication, No. 25 in the English language series from the Norwegian Tunnelling Society NFF, has – as always – the intention of sharing with international colleagues and friends the latest news and experience in the use of the underground. This time we want to show our various use of rock caverns, thus the title “Norwegian Rock Caverns”.

One good reason for selecting this topic and title, is that next year, 2017, the World Tunnel Congress (WTC) will take place in Bergen on the Norwegian west coast. And the slogan for the congress is “Surface Challenges, – Underground Solutions.” As we expect that many of the readers of this publication will take part in the WTC in Bergen, we have included examples of rock caverns located in or near Bergen, -Bergen known as “The city with seven mountains.” Technical excursions to many of these caverns will be offered to the WTC participants.

Publication 24: Health, Safety and Environment in Norwegian Tunnelling

The present publication, No. 24 in the English language series from the Norwegian Tunnelling Society NFF, has – as always – the intention of sharing with colleagues and friends internationally our latest news and experience in the use of the underground, this time with focus on health, safety and environment.

In 2004 NFF issued the Publication No.13 called Health and Safety in Norwegian Tunnelling. During the period 2004-2015 laws, regulations and critical threshold values were modified followed by controls, measurements and enhanced attention from owners and society on HSE-matters.

Publication 23: Norwegian Tunnelling Technology

Publication 18: Subsea Tunnels

NFF – the Norwegian Tunnelling Society, as part of its activities, prepares technical publications in the English language. These publications focus on selected segments of underground construction.

NFF issued its first publication on subsea tunnelling in 1991. 18 years have passed, numerous new subsea projects were implemented, the industry has gained experience and techniques were improved. In conclusion, it is time for an update. The intention, as always, is the sharing with colleagues and friends internationally newly gained experience.

The high level of subsea tunnelling activities taking place in Norway is a consequence of the special topography of the country with mountains, fjords and outlaying islands in combination with national support for improving communications in the coastal areas. Priorities were not necessarily governed by cost-benefit analyses.

Publication 17: Underground openings – Operations, maintenance and repair

The present publication, No. 17 in the English language series from the Norwegian Tunnelling Society NFF, has – as always – the intention of sharing with our colleagues and friends internationally the latest news and experience

Publication 15: Sustainable underground concepts

Norway is a mountainous country. Topographical features along the western coastline are long fjords cutting into steep and high mountains. The south-eastern and middle part of the country takes on smoother forms; still dominated by mountains and rocky underground.

The topography hence creates necessity, opportunities and challenges for rock engineering in the development of the infrastructure of the country. Commended virtues in the engineering sector are competence, ability to find new solutions and conscious approach with regard to environment and costs.

Publication 14: Norwegian Tunnelling

The Norwegian landscape and topography is characterised by long and deep valleys and fjords cutting into high mountains.

The rock mass left after tectonic activities and several periods of glacial erosion, is suitable for tunnelling, still holding numerous challenges for the tunnellers. Rock tunnels have been found to be an efficient link to overcome infrastructure challenges.

At the same time these topographical conditions enable a wide range of utilisation of the rock mass for the benefit of the public. Hydropower projects take advantage of the highly elevated water reservoirs and utilises the rock to host tunnels and caverns.

Publication 13: Health and Safety in Norwegian Tunnelling

Norwegian tunnelling is mechanised, with extensive use of self-moving units for all processes. This means that the heavy, and partly dangerous, manual work that used to characterise tunnelling is strongly reduced.

The typical Norwegian tunnel worker is multi-skilled. The crews are organised as autonomous work groups, lead by qualified shift foremen. The employer and crews usually negotiate a bonus system based on production achievements enhancing motivation geared towards production and award.

The experience over the last years show that this system can be well combined with high emphasis on health and safety.

Publication 12: Water Control

The allowable amount of water inflow is determined by the actual circumstances. For some projects the practical limitations related to the excavation process or to pumping capacity govern the requirements. This may be the case in subsea tunnels for which an allowable remaining inflow of 30 litres per minute and 100 m tunnel length is typical.

More often, below sensitive natural recreation areas, or below cities with buildings founded on settlement sensitive soils, very strict requirements apply. The remaining inflow may in such cases have to be restricted to the range of 2 to 10 litres per minute per 100 m. The main point is to construct a tunnel that is tight enough, in terms of fulfilling a project specific target on allowable water inflow.

Publication 11: TBM Tunnelling

The scope of the present volume is TBM tunnelling in Norway. The first TBM project executed in Norway dates back to 1967. It was called promising, in spite of low penetration and high costs.

Later TBM development is closely connected to the development of high performance machines, increased thrust per cutter and improved bit technology. James S. Robbins and Robbins machines played an important role in this process.

Publication 10: Publication 10 Urban Tunnelling

The scope of the present volume is to present the variety of purposes where underground facilities have been used in and around the capital city of Oslo.

Although a small city, Oslo has experienced the common problems of urbanisation, such as traffic jams and lack of space for building purposes.

These restrictions to development have largely been solved by locating transport systems and other public facilities in underground tunnels and caverns.
