ABSTRACT Contractor selection is one of the important aspects in the field of project management as it has a big influence on project and its success. Without a precise method for selecting the best contractor, the choice of contractor for a project may affect the successful completion of project. Analytical Hierarchy Process (AHP) is one of the decision making techniques used in construction management for selection of contractor. AHP helps the construction sector in two ways; first, the prequalification criteria’s focus on degree of importance, and second, it implements a multi- criteria AHP approach which calculates priority vectors for evaluating and selecting the best contractor. The other TOPSIS method focuses on selecting the most suitable contractor by calculating shortest distance from positive ideal solution and farthest distance from negative ideal solution. This dissertation work consists of decision hierarchy for selection of best contractor from various alternatives and forming of theoretical model based on methods. Data is collected in the form of questionnaire survey from contractors and project managers in different fields which is further used in pair wise comparisons.
