Cataloging and statistical evaluation of common mistakes in geotechnical investigation reports for buildings on shallow foundations

Özyurt, Gökhan
Information presented in site investigation reports has a strong influence in design, project costs and safety. For this reason, both the quality and the reliability of site investigation reports are important. However in our country, geotechnical engineering is relegated to second place and site investigation studies, especially parcel-basis ground investigation works; do not receive the attention they deserve. In this study, site investigation reports, that are required for the license of design projects, are examined and the missing/incorrect site investigations, laboratory tests, geotechnical evaluations and geotechnical suggestions that occur in the reports are catalogued. Also, frequency of each mistake is statistically examined; for geotechnical engineers, recommendations and solutions are presented to help them avoid frequent problems.
