A study on the factors causing delays in the installation of marble, granite, high building construction. Researchers have introduced a theory of project management 1E 4M data analysis with a focus on in order to determine the factors that affect the delay makes the installation of marble, granite, high building construction delays. By comparing the index impact severity (Severity Index: S.I) of each of the factors that affect installation time in order to determine the factors that occurred to delay the project, installing marble granite stone in the construction of high buildings, even more. Researchers have determined, for example in a research group composed of. Project owners group-a group of contractors and consultants.
