Importance of the Factors Affecting the Delays in the Projects of Construction of Collective Housing in Algeria - Program Rent-Purchase

Abstract

Faced with rapid urbanization and increasing demographic pressure on Algerian cities, housing policy in Algeria has evolved considerably over the past twenty years. However, the construction process is subject to many variables and unpredictable factors, which result in delays in project completion. It is therefore essential to identify and evaluate the relative importance of the main factors affecting delays in collective housing construction projects according to the vision of professionals and experts established in Algeria. Indeed, we focus our attention on the point of view of clients, consultants, designers and contractors to assess the relative importance of 67 delay factors. In total, 37 valid responses were analyzed and ranked. The results indicate that the 5 most important causes are Delay in payment of performed work, Shortage in skilled workers, Bureaucracy in public administrations, Delay in the provision of on-site public services and difficulties in financing the project by contractor. This study is hoped to help the practitioners to implement the mitigation measure at planning stage in order to achieve successful construction projects.
