Unlike manufacturing supply chain the modus operandi of construction supply chain is not up to date. It might be attributed to the context of construction projects and the structure of construction industry. The formal and informal control mechanisms are well established in retail and manufacturing supply chain and it reflects in product performance. However, this is not evident in case of construction supply chain and project performance is often chaotic. In case of large and complex construction projects, the client-contractor dyad needs to appropriately seek input control, behaviour control and output control for successful project delivery. In light of Organization control theory and review of literature on construction supply chain, this study evaluated the three control mechanism-input control (project risk and reward power, intra-project communication), behaviour control (opportunism) and output control (project performance) using structural equation model. The survey data is collected from the 258 construction professionals working in construction projects in India. It is revealed that input control in terms of project risk and reward power, intra-project communication largely influences behaviour control in terms of opportunism. However behaviour control does not substantiate output control in terms of project performance as expected, rather the direct effect of input control mechanism on output control is revealed.
