oa Civil Engineering = Siviele Ingenieurswese - Are we getting what we pay for from geotechnical laboratories? : geotechnical engineering
Geotechnical engineers use the results of soil tests when assessing the likely behaviour of foundations and other geotechnical structures and assume professional responsibility for these assessments. But how reliable are the results they receive from the soils laboratories? This article compares the results of basic soils tests on two samples sent to four commercial soils laboratories in the Gauteng area in late 2006. The variation in the values obtained was sufficiently wide to lead to an incorrect assessment of soil behaviour. A follow-up trial was carried out at the beginning of 2008. No improvement in the consistency of results was noted. Possible ways of addressing this problem are explored
