Abstract

In terms of the importance of constructing mega projects in and the significance of ensuring the public utilities intersecting with such projects, this research was initiated with the objective of automating the management of diverting such public utilities, in terms of the 3 pillars of the Project Management Triangle “PTM” (i.e. Cost, Time and Value). Principally, literature in the field of constructing mega projects in old cities were assembled and scrutinized. Based on the scrutinized literature, clear was that the main construction challenge was attributed to the absence of precise maps and accurate data. Moreover, the literature emphasized that research is ought to bridge the knowledge-gap and ought to establish a paradigm-shift within the assessment methodologies. A project was considered as a case study and was assessed manually. It comprises the diversion of a large collector sewer in KitKat district in Cairo during the construction of the Diverting-Box-Station of Cairo UG Metro, where the 3rd subway line intended to connect the highly dense zone and solve traffic difficulties. Three Project Scenarios (i.e. 1, 2 and 3) were proposed. Regarding the 1st, it intends to construct a pump station to elevate the sewage water. As for the 2nd, it plans to reorient the sewage pipe to be a gravity pipe. Converging on the 3rd, it anticipates the upgrading of the entire network. A structured questionnaire was formulated. It encompassed the attributes of the 3 pillars of PMT (i.e. Cost, Time and Value). The cost considered the Initial Cost and Running Cost. The Time reflected the Construction Time and Maintenance Time. The Value highlighted the Environmental Impact and the Performance so as the Constructability. The questionnaire surveyed the weight “W” and the impact factor “I” of each attribute. The questionnaire was distributed electronically among a selected population of participants in complex project systems. Based on the experts answers, the attributes were ranked manually by implementing 2 Multi Criteria Decision Making “MCDM” methods, where the ranking process prioritized the 2nd Project Scenario, as it fulfilled the 3 pillars of the PMT. Moreover, a model was developed automated the ranking and assessment processes of diverting utilities on complex projects by implementing MCDM and PMT. The developed model was utilized to 2 projects (i.e. constructing a bridge in Cairo Centre and another in New Cairo), while diverting public utilities. The automated output assessed and ranked the 2 projects efficiently. The research results highlighted the importance of automating the assessment and ranking processes during constructing new mega
projects, while diverting the public utilities for the sake of constructing the project.
