Japanese Design-Build (DB) is unique and different from the DB implemented in other parts of the world, especially in advanced western countries like the US and UK. The purpose of this research study is to analyse the uniqueness of Japanese DB, based on allocation of responsibility and risk in the standard construction contracts. A comparative analysis was carried out to ascertain the similarities and differences between Japanese DB contract and Japanese traditional as well as western contracts as represented by the standard contract forms of the American Institute of Architects and the Joint Contracts Tribunal. Contract clauses are extracted and broken down into eight elementary components in order to clarify the responsibility statement. For each responsibility, the appropriate project phases (whether pre-design, design, construction or completion of each responsibility), risk contained in the responsibility and degree of each party’s involvement were indicated. To make the three contract series with different configuration structures comparable, ten headings of contractual issues were established. The comparative analysis revealed that the differences between Japanese and western contracts basically revolve around the clarity of the responsibility description, the process and approach of decision making, and the degree of involvement by the Owner. The finding supports the hypothesis that the Japanese DB contract does not properly represent the actual Japanese DB; instead, it suggests that the Japanese DB is closer to the Japanese Traditional method. The hypothesis that the Japanese DB is nothing like the DB in other global DB standard contracts, as represented by the AIA-DB and JCT-DB, was also verified. It has been validated that the Japanese DB is close to the Construction Manager as Constructor of the AIA. The Management Contract of the JCT is found incomparable to the Japanese DB due to different risk placements despite being designed for the single responsibility of contracting construction contracts. Based on a comparative analysis, contractual issues and allocation of responsibility and risk (which are essential for a standard contract for inclusion in a future Japanese DB contract) are highlighted.
