- Description
- Obtaining competitive quotations from suitably qualified subcontractors at tender time can significantly increase the chance of winning a construction project. Amidst an increasingly growing trend to subcontracting in Australia, selecting appropriate subcontractors for a construction proiect can be a daunting task requiring the'analysis of complex anddynamic criteria such as past performance, suitable experience, track record of competitive pricing, financial stability and so on. Subcontractor selection is plagued with uncertainty and vagueness and these conditions are difficult to represent in generalised sets of rules. Decisions pertaining to the selection of subcontractors at tender time are usually based on the intuition and past experience of construction estimators. Case-based reasoning (CBR) may be an appropriate method of addressing the challenges of selecting subcontractors because CBR is able to harness the experiential knowledge of practitioners. This paper reviews the practicality and suitability of a CBR approach for subcontractor tender selection through the development of a prototype CBR procurement advisory system. In this system, subcontractor selection cases are represented by a set of attributes elicited from experienced construction estimators. The results indicate that CBR can enhance the appropriateness of the selection of subcontractors for construction projects.
