are the one of the main reasons why surveyors purchase errors and omissions insurance. Some examples are: Transposing digits i.e. writing 144.03 instead of 114.03 Recording the wrong point number for a traverse point. Not recording a change in prism pole height. Blunders that cause large errors in the final survey are

Department of Survey and Mapping. Temporary Bench Mark (TBM) • A moveable object that has a known height above a pre-defined level. This level is not absolute and is defined locally by the surveyors for the purpose of the survey. Based on the TBM the survey may then later be reduced to absolute levels if the level of TBM is known. 8
