Our mission at Ista Sanj Daghigh Consulting Engineers is to provide specialized surveying services to civil projects. More than 200 projects in geodetic deformation monitoring survey of large dams and structures have made Ista Sanj Daghigh Consulting Engineers Company the most qualified consulting partner for precision surveying engineering services in Iran.

CEO TEXT

One of the major concerns of planners, constructors and users of large structures these days is to make sure projects are running effectively. This objective is to a large extent achievable by installation and continued monitoring of precision instruments. But precision instruments installed inside structures will lose their efficiency in the course of time and it is necessary to use a more reliable microgeodetic method to monitor both structures and performance of precision instruments. As the first private company of Iran active in the field of Geodetic Deformation Survey, Ista Sanj Daghigh Consulting Engineers Company was incorporated in 2003 with the core mission of providing Geodetic Deformation Survey services to civil projects. We have benefited from expertise of proficient employees and state-of-the-art instrumentation. Our company has signed more than 200 contracts so far for providing Geodetic Deformation Survey services. Currently major projects throughout Iran are under monitoring of our company and as the employers certify our services are at international quality standards level. Our constructive interaction with National Cartographic Organization paves the way for achieving long term objectives of our company.
