Metrology in geotechnical standards for in situ testing and geophysical survey

Joek Peuchen

Abstract

This paper presents an overview of achievements and hurdles in international standardisation of geotechnical practice for in situ testing and offshore geophysical survey. Standardisation of in situ testing is progressing from a historic, specification-type approach to a performance-based approach. The tools for actual demonstration of achieving the performance-based requirements for accuracy are shown to be lagging behind. Work is now underway for standardisation of sub-seafloor geophysical surveys for geotechnical applications. Standardisation of metrology issues proves challenging. The survey industry is generally familiar with specifying equipment and procedures, with few systematic tools for estimating data point uncertainty.
