In this work I have chosen to address some of the problems I myself dealt with during my time on project GC Hedenäsetand how we solved these problems. To answer my questions, there is a description of the basics of measurement technology as well as shorter descriptions of different types of equipment thata measurement technician may use, easier as well as more advanced equipment.This report is intended to highlight the problems that can be encountered when using modern technology as well as the alternative solutions available when this technique doesn’t work.
