ABSTRACT
Complex management of construction and engineering projects needs reliable instruments and tools to achieve highest efficiency levels. It is required specially during tunneling or deep digging which might effect at buildings and objects located in the influence zone causing displacements and cracks. One of the way of controlling the site in this zone is to use manual or mechanical crack meters located at buildings walls [1,2]. This article describes results of tests of a new digital crack meter concept. This new solution based on photogrammetry software and mobile devices hardware enables for precise, fast and reliable measurement of crack wideness. First stage of measurement module tests are presented in this paper.
