Applied GIS to the Monitoring of Building Work Case Study: Construction of 2000 Houses in Ghadames-Lybia
Chaâbane and Co Tunisian company has been contracted by “El Jihez Iskene and El Marafek Libya” to achieve 2,000 villa’s in Ghadames and Derj (Nalout). The agreed implementation period was 30 months. This project covers an area of approximately 260 ha. The extent important project and the remarkable number of housing building and the diversity of construction activities (Reinforced concrete foundation, reinforced concrete in elevation, masonry, cladding, etc.) deserve the establishment of an efficient management of work through the control of the fixed time and the reserved budget. To do so, a process of planning, organization and management as well the affected resources must be put in place. This process is to break down the project managing in simple tasks or activities, to provide forecasts for these tasks and then to monitor their progress. The conventional planning tools (Primavera, Msproject, …), generally adapted by project managers, allow a representation in time of the tasks to be performed, specifying the executions’ duration and conditions of each one. However, this representation does not allow a spatial or geographic monitoring of the performed tasks within the scope of project intervention. From then, the application of Geographic Information System (GIS) complements the above monitoring tools for civil engineering projects occupying large areas on the one hand and having different types of scattered structures on the other. In fact, GIS can identify the collected data on task progress, can structure and present them in maps form in order to graphically and geographically visualize the overall progress and to conveniently extract useful summaries to the decision making.
