TIME DELAY DISPUTES IN CONSTRUCTION INDUSTRY AND PREDICTION MODEL

Construction disputes are one of main obstacles, which face the construction projects, most of construction projects are long period and complex, often finish out of planned period and budget. The main causes of construction dispute are accerlation, co-ordination, differing goals, delays, design, engineer, project complexity,quality and workmanship, site conditions, tender, variations and value engineering. It is essential to study and analyze causes of construction time delay disputes. This paper studied a list of time delay disputes causes gathered from literature having different types of construction, different countries and different periods .A questionnaire and personal interviews have formed the list 110 time delay disputes causes. The questionnaire survey was distributed to 100 construction participants who represent consultants, contractors and owners. The interviewers were stratifying a minimum of five years up to above 30 years’ experience in construction projects in Egypt. So, practitioners were selected to be from seniors to Managers in large construction organizations, a number of 40 responds were Suitable for analysis. Relative Importance Index (RII) is calculated and according to the highest values, the top fifteen causes for time delay disputes of construction projects in Egypt are determined. It is necessary to provide a prediction model that can predict by construction time delay dispues as percentage and give recomedation to reduce the expected time delay disputes. The inputs of this system include project information, probability of occurring the most fifteen factors of time delays disputes and the proposed type for analysis (manual/equal weight/automatic). The outputs of the proposed Model will be the expected percentage for occurring time delay disputes, recommendations for reducing time delay disputes and summarized report consist from one paper including project information, expected percentage for time delay disputes and the recomendatios. Some guide lines will be systematically provided to show how can the suggested model be operated, finally it is applied case study related to arab contractors company on the model and there is completely matching between the case study and the model output, the model expected occurring dispute by percentage 83% (very high), The case study confirmed that occurring dispute between the owner and the contractor and compensation of the contractor.
