Efforts to ensure standards for established and stipulated procedures for laboratory testing enables NGI, and all others who contribute to build and develop Norway and the world, to do this on a responsible and secure basis.

Rune Dyvik is a specialist and technical lead for NGI's geotechnical laboratory in Oslo. He is an American citizen and obtained his PhD in geotechnics from Rensselaer Polytechnic Institute, Troy, New York. Rune came to NGI in 1982 and has since then worked on geotechnical laboratory testing as well as model and full-scale testing in the laboratory and in the field. He is the author/co-author of more than 40 publications for peer-reviewed journals and conferences. His extensive experience from the work at NGI is perfect for the work of standardization.

"Since the beginning of the 2000 's I have been a member in the Standards Norway (SN) Committee for Geotechnical Laboratory and Field Investigations, SN/K081, a so-called 'Mirror Committee'. This Committee determines how Norway should deal with new standards from the EU (CEN standards). They can also introduce additional provisions or supplement with guidance, especially applicable to Norwegian conditions. It is this Committee that develops new Norwegian standards and maintains existing Norwegian standards within this subject (the NS-Series)", explains Rune Dyvik.

Norwegian contributions abroad

Since 2010 Rune has also been a member in the ISO-CEN Committee TC341 Working Group 6 for geotechnical laboratory testing. This Committee is responsible for managing, implementing, and quality assurance of European standards related to geotechnical laboratory testing. A standard from this working group that is approved and published by CEN, is recorded and implemented by the ISO (International Standards Organization) and will be effective in a world standard. This working group has now developed 12 standards.

"The USA has its own standardization system, ASTM International (formerly the American Society for Testing Materials). It is a not-for-profit organization that provides a forum for the development and publication of international voluntary consensus standards for materials, products, systems and services. Members are professionals in their relevant specialties and disciplines, and come from about 140 countries", explains Rune.

The members of ASTM International represents manufacturers, users, government agencies, research and academia, and the standards are prepared by a number of committees and their subcommittees. Rune was approved member of ASTM "Committee D18 on Soil and Rock" in 2012, and is a member and active participant in six of the over 20 subcommittees to D18. The D18 Committee is responsible for about 400 standards within soil and rock.

"In January this year I was appointed chairman of the Subcommittee D18.05 Strength and Compressibility of Soils, and I am also the Secretary of the Subcommittee 'D18.09 Cyclic and Dynamic Properties of Soils'. D18 has meetings twice a year. In the course of our four-day meetings, they discuss, evaluate and perform quality-control of new standards, as well as adjustment and upgrading of existing ones", says Rune.

The fact that NGI and Rune Dyvik are active in standardization work on the "Strength and Compressibility of Soils" for large parts of the world, is directly in line with the mission of NGI. "Rune's substantial efforts within the standardization work is a significant contribution so that the geotechnical community can develop sustainable solutions for both industry and society, ensuring that we live, build and travel on safe ground", concludes Morten Sjursen, head of NGI's section for laboratory and model testing.
