Relationship characteristics within the supply chain of small and medium-sized construction enterprises in Thailand

The Small and Medium-sized construction Enterprises (construction SMEs) in Thailand face challenges like high fragmented structure and low productivity. Many industries improved their business performance using the supply chain integration. This research was conducted by interviewing 14 small and medium Thai building contractors to understand the features and relationship characteristics of the supply chain of construction SMEs. The study reveals that the linkages between the small and medium general contractors and other supply chain members are based on personal trust rather than contract laws, there is no systematic procedure to manage the relationship with clients during the project execution, and social connections help to maintain long-term relationship with clients. Based on the working behaviour and commitment to long-term relationship, six forms of relationship with supply side members are proposed. Finally, improvement measures for the supply chain integration of the construction SMEs in Thailand are presented.
