- Abstract:
In the construction industry, problems such as budget overruns, extended schedules, low quality work and poor safety standards still exist due to not selecting the best contractor to complete a project. To select the best contractor, an owner needs a rational approach to evaluate candidate contractors. This evaluation involves mainly developing criteria and developing a model to interrelate these criteria. However, at present there is no consensus for the selection of a common hierarchy/set of criteria, showing a knowledge gap that needs to be bridged. Moreover, all existing models have a lack of integration in the joint area of simultaneously putting together subjective inputs of multiple decision-makers, covering elements of risk and uncertainty, and offering computer interaction. This presents another knowledge gap that needs to be filled. Therefore, the main research aims were to originally contribute to (1) developing a common set of criteria based on existing organisational units of contractors and (2) developing a more realistic working model including the necessary capabilities mentioned. The methodology used in this research was an integrated approach to the suggestion and development through literature review, questionnaire survey, and model tests. The Thai construction industry was used to investigate tender evaluation procedures, criteria and models. The writer's ideas, together with concepts and techniques mainly from construction engineering, operations research, systems engineering, social sciences and computer sciences were blended into the suggestion and development. A hierarchy/set of contractor ability criteria was developed on the basis of a combination of organisational units of contractors and the results of questionnaire analyses, which is the initial initiative of this research. This hierarchy/set incorporates physical characteristics of contractors, which appear to offer a common set of contractor ability criteria. This common set could then result in the reduction of worldwide repetitive effort in developing contractor ability criteria thereby possibly decreasing world-owners' expenses. Using the hierarchy/set of contractor ability criteria as a basis for its development, the multicriteria and multidecision-makers' model proposed in the research can overcome the mentioned lack of the existing models by simultaneously including the necessary capabilities mentioned. The vital theory behind the model was the method, using a combination of a utility function and a social welfare function, identified as state-of-the-art. This method provides the consideration of both risk arising from uncertainty and multiple decision-makers' involvement. To assemble the model, Microsoft Excel performed calculations whilst Visual Basic for Application (VBA) undertook interaction. The interactive capability of the model offers the flexibility to absorb changes, both in contractor ability criteria and in multidecision-makers' subjective inputs. With this flexibility, the model could be used in any country. For these reasons, the model has advantages over all existing models in tender evaluation. The model tests for user friendliness, verification, sensitivity analysis and validation showed that the integration of multidecision-makers' subjective inputs, elements of risk and uncertainty and computer interaction was a rational and realistic approach in solving tender evaluation problems. The research provides two main beneficial results filling the two knowledge gaps. One is a common hierarchy/set of contractor ability criteria including physical properties of contractors (i.e., hierarchical organisational units of contractors), which potentially leads to the decrease of the waste of world-repetitive resources spent. The other is a more realistic working model (the multicriteira and multidecision-makers' model) including multidecision-makers' subjective inputs, risk arising from uncertainty and computer interaction; which results in a saving in time and higher efficiency of tender-data analysis. This then helps to reduce the construction problems mentioned. Consequently, the owner will enjoy the future growth.
