Selected methods of documenting and assessing the technical condition of underground infrastructure

The paper will present modern methods of documenting and assessing the technical condition of underground infrastructure. Plans will be discussed that allow verifying the current geometry of underground infrastructure walls as well as detecting leaks or locating structural damage. The advantage of conducting measurements with automatic devices and digital image recording is the creation of a numerical model of the inner surface of a collector or pipeline. Such a solution gives the possibility to make an automatic comparison of possible changes between individual measurements. During the analysis, it is possible to identify areas with differences in geometry greater than acceptable for further research. Performing a numerical analysis eliminates the human factor of subjective evaluation of changes. The presentation will outline the capabilities and limitations of the various methods and how their results can be used in documenting and assessing the condition and designing possible repairs and upgrades. This is of particular importance in critical infrastructure sections in urban areas, as well as in areas of mining damage.
