Multi-Laboratory Assessments of Cyclic Soil Behaviour
On some large projects, testing may need to be shared between multiple laboratories, in order to achieve project deadlines. In these cases, it is the authors’ experience that unless great care is taken defining advanced testing requirements, beyond simply stating a prescribed testing standard, differences in test results are common. Often these are due to slight discrepancies in specimen set-up or testing, or in the equipment used for testing. This paper presents some examples of testing performed by multiple laboratories, or with multiple types of equipment, to illustrate these issues. However, it is also the authors’ experience that detailed and interactive communication of project-specific testing requirements enables the majority of differences to be prevented, thus allowing multi-laboratory testing on the majority of projects.
