Although this subcontract model is more convenient and easy to manage, we still need to think about if it has the the advantages of distracting risks and lowering fixed cost. Thus, on the part of a large construction company’s manager, he should take the very question -whether they can deal with partial construction into serious consideration. This research is to help managers to build up the effective model to evaluate make or buy decision based on value chain analysis and cost drivers in Portre’s”Competitive Advantage”.It also utilizes fixed cost and variable cost in the economic model to analyze the unit cost, then evaluate the constructions should adopt make or buy decision. In this case study, the research takes retaining wall formwork for example. First, break down value activities and set up the value chain. Next, evaluate make or buy decision of formwork through cost drivers. Finally, analyze the unit cost by the economic model. The outcome confirms that the retaining wall formwork has the potentiality to be made by construction company itself. And this leaves the managers to think about the ways further more.
