About Us

Background:

Ista Sanj Daghigh Consulting Engineers Company was incorporated in 2003 by some of the experienced geodesy specialists with the mission of providing Geodetic Deformation Survey services to large dams and structures as well as providing maps needed by civil projects. In order to provide geodetic services at international quality standards level and for the purpose of meeting the requirements of dam building employers, Ista Sanj Daghigh Consulting Engineers Company procured precision geodetic observation instruments from internationally renowned manufacturers. We managed to sign our first contract for provision of geodetic deformation survey services with one of the top structures in Iran, i.e. Milad Tower.

Ista Sanj Daghigh Consulting Engineers Company received the certificate of qualification from the State Management and Planning Organization in mid 2003 and then expanded its operation and signed several contracts with different companies regarding geodetic deformation survey services. We achieved a special position among employers through timely and proficient fulfilment of projects. During 16 years of our operation we managed to provide geodetic deformation survey services at highest international quality standard levels for the main dams throughout Iran including Shahid Abbaspour, Masjed Soleiman, Dez, Seimareh, Karun-3, Karun-4, Amir Kabir, Siah Bisheh, Hirvi, Qucham, Balarud, Silveh, Aras-2, Saveh, Ardebil, Sabalan, Saruq, Sivand, Garmi Chai, Kalan Malayer, Ekbatan, Kamal Saleh, Zirdan, Qal’e Chai in Ajab Shir, Aydughmush, Siahbisheh, Zonuz, Arasbaran, Baft, Damghan, Mamlu, Gilane Gharb, Zagros, Sarab Aqcheh, Kamaneh, Qareh Achaq, Panzdahe Khordad, Roodbar lorestan, Hana, Howzian, Milad Tower, etc.

In addition to providing geodetic deformation survey services to dams, we also provide large scale dam lake maps for Gotvand, Masjed Soleiman, Siah Bisheh, Tazehkand, Bafrajerd and some other dams and also drew topographic maps for watercourse rectification for rivers in cities of Ahar, Varzeghan, Azar Shahr and Ajab Shir. None of the above missions was achievable without our trust in God and the full dedicated support from our committed staff. We are looking forward to expanding our operation oversees in the near future by signing international contracts.

Completed or In-Progress Projects:

Ista Sanj Daghigh Consulting Engineers Company is active in the following two major areas:

  • Providing geodetic deformation survey services to large dams and structures; and
  • Drawing large scale urban and non-urban topographic and cadaster maps.

From 2003 to date Ista Sanj Daghigh Consulting Engineers Company has signed more than 200 contracts with government employers for providing geodetic deformation survey services to large dams and structures and drawing topographic and cadaster maps. During 16 years of operation our company has managed to provide geodetic deformation monitoring survey or precision surveying services to major national projects including: Karun-3 Dam and Power Plant, Karun-4 Dam and Power Plant, Milad Tower, Nowsud Tunnel (27 Km long), Dez Dam, Shahid Abbaspour Dam, Amir Kabir Dam, Seymareh Dam, and Lorestan Roodbar Dam, as well as the largest Semi-Submersible Drilling Iran Alborz and lines 2 and 3 of Mashhad underground. Execution of so many contracts with major national projects within 16 years, shows the level confidence and trust that employers have in the services provided by our company.

With regard to drawing cadaster maps of dam reservoir lands and creation of a GIS database, we have so far drawn cadaster maps for 50.000 hectares of dams and civil projects lands and we have also created GIS database for land acquiring for Upper Gotvand Dam and Power Plant, Siah Bisheh Dam and Power Plant and Masjed Soleiman Dam.

Staff

Currently 37 specialists and technicians are working full time for Ista Sanj Daghigh Consulting Engineers Company. 

 

Surveying and Geodetic deformation survey Equipment List:

Since different instruments are used for providing geodetic deformation survey services, Ista Sanj Daghigh Consulting Engineers Company has procured precision equipment. We are ready to carry out four simultaneous geodetic deformation survey projects with a full list of instruments.

In addition to the above equipment, we also have Leica 1230 satellite receivers (RTK) and we can perform real time topographic map operations. We also use a combination of RTK satellite receivers and NAVISOUND 210 echosounder for sounding and hydrographic operations. Table 1 lists the equipment used by Ista Sanj Daghigh Consulting Engineers Company.
