Design/Bid/Build type of Contract to produce a work is the only type for common understanding in Taiwan; the new types of Contract to produce a work such as Design/Build and Contract for Engineering, Procurement and Construction are rarely known. Design/Build contract has more frequently been used by the government agencies in recent years. According to the Yellow Book of FIDIC, the main difference between the Design/Build contract and traditional Design/Bid/Build type contract is that the Design/Build contract has no concrete design, but normally only has a relative abstract bidding document and requirements planning. The another type of Design/Build contract is Contract for Engineering, Procurement and Construction, its model contract is described under the Silver Book of FIDIC which is more risky for the contractor. This paper has analyzed the difference of these two type of Design/Build contracts, especially about the risk to the contractor.
