Planning for Gas Pipeline Construction

Gas transmission trunk lines, as vital energy distributor, play strategic role in any country. Iran, as the second-largest country in the world’s gas reserves, can increase its global position by investing in this bounty. Hence, Completing the projects in minimum possible duration will increase the rate of return on investment, especially for gas exportation projects.
The collaboration between Tecnosa R&D Center and Iranian Gas Engineering and Development Company has been started in fall 2017 to enhance the planning phase of pipeline construction projects. The main purpose of this collaboration is to develop an automated system that enhances the project cost and time estimation, project resources optimization, and project schedule. The results came from this system are utilized for bidding documents and later construction supervisions. Pilot project of this system is the 56 inches’ pipeline of 9th trunk line, length of 106km between Dehgolan and Miandoab (2nd part).


Gas pipeline construction projects are long in terms of length and they have a repetitive nature. These characteristics cause the project divisions and resource allocations to directly affect the project progression. Therefore, project team of Tecnosa R&D Center decided to use Discrete Event Simulation (DES) and Linear Scheduling Method (LSM) to reach the collaboration goals. In addition, the Project Management Information System (PMIS) is implemented for organizing project data and performing estimations based on date from prior projects.


System features for planning gas pipeline construction projects:


  • Extracting points and volumes from project drawings
  • Performing automated quantity take-offs
  • Estimating the project’s total cost and duration
  • Dividing the project to manageable portions
  • Analyzing the effect of weather on project progression
  • Analyzing the effect of resources and equipment on project progression
  • Analyzing the effect of delays on project progression
  • Project planning based on linear scheduling method (LSM)
  • Project planning based on critical path method (CPM)
  • Performing line of balance (LOB) analysis and identifying project bottle necks
  • Optimizing project’s total cost and time
