Natural gas pipeline construction (NGPC) projects are inherently includes high changefulness like any other construction works. Considering that variability, it can be stated that to make an accurate cost estimation is difficult. The main objective of this paper is to achieve a coherent mathematical equation to be able to make a preliminary cost estimation of NGPC costs. To this end, a number of pipeline cost data, which is in US dollar currency, was obtained for the period 1986-2010. With this data, a simple regression equation was tried to be revealed by working through statsmodels, one of the libraries used for the Python programming language. It was concluded that a significant part of the NGPC cost could be explained with the diameter and length variables. In this respect, this paper has the potential to assist the institutions responsible for the execution of the NGPC processes of the Turkey or the contractors considering investment or at the decision-making stage. Moreover, the paper presents a first attempt at both predicting of NGPC costs in Turkey and executing that operation by using Python programming language. |
