Evaluation of the Construction and Investment Process of a High-Pressure Gas Pipeline with Use of the Trenchless Method and Open Excavation Method. Analytic Hierarchy Process (AHP)

Abstract

The study presents the application of multi-criteria analysis, i.e., the Analytic HierarchyProcess (AHP), for the evaluation of investments related to the realisation of a high-pressure gaspipeline. The authors evaluated the realisation of the gas pipeline with the use of alternativemethods: the trenchless Horizontal Directional Drilling (HDD) method and the open excavationmethod, based on the example of the construction of a high-pressure gas pipeline DN1000. Sectionslocated in naturally valuable areas on the route of the pipeline Wierzchowice-Kiełczów (Poland)were analysed, on the section from the valve station in Czeszów to the Kiełczów node. The researchconsidered the following criteria: technical costs, economic costs, social costs, and environmentalcosts. The sum of these partial estimations is the “total cost” of the investment. Research revealedthat the technical costs of the open excavation method are in all cases higher than the technologicalcosts of the trenchless method during the realisation of a gas pipeline (in the AHP analysis, theyreceive an average score of −4 or −3, compared to a score of −2 for the HDD method). On the otherhand, the economic costs are comparable, with a slight advantage for the HDD method. The overallscore for the open excavation method obtained with use of the AHP multi-criteria evaluation is, fordifferent variants, approximately −19, while the evaluation of the realisation of a gas pipeline withuse of the Horizontal Directional Drilling method gives a score from −15 to −10, depending on thesection.

Dynamic Portfolio Selection in Gas Transmission Projects Considering Sustainable Strategic Alignment and Project Interdependencies through Value Analysis

“…Some criteria from the technical concerns are suggested to be integrated into the sustainability assessment [30]. Kwast-kotlarek and Hełdak [31] considered four evaluation criteria, including technical costs, economic costs, social costs, and environmental costs for the evaluation of gas pipeline investments.…”

The Main Impacts of Infrastructure Works on Public Roads

“…The partial or total interdiction of vehicle traffic is related to the full or partial interruption of local traffic, increasing the possibility of traffic jams and route changes [4,19,[21][22][23][24][25][26][27][28][29][30][31][32][33]. Generally, the locations that suffer the most from this impact are those located close to large cities where urbanization is denser and the streets may be narrower [24].…”

“…Changes in local pedestrian traffic refer to route changes and lengthening of the route. They occur mainly due to the closing of lanes, blocking sidewalks, and the redirection public transport [4,[21][22][23][28][29][30][31][32]. Sorokin [29] classifies pedestrian and vehicle traffic as extremely important since the most valuable resource for citizens is the time spent commuting.…”

“…The reduction in the usable space used by the population is related to the decrease in areas used for parking and living [19,21,25]. According to Çelik [19], many residents find it challenging to park, even close to their homes.…”

“…Some works address impacts related to specific works, such as the subway [4], to specific impacts, such as noise pollution [14,15], or focus on dimensions of sustainability [16][17][18]. On the other hand, more comprehensive works address more than one type of impact and construction [4,11,[19][20][21][22].…”
