 Outline of the Division |
| In order to improve infrastructure projects implementation to be more effective, efficient and accountable to the public, the Construction Management Division performs research on methods of managing infrastructure developments from all aspects of the processes including planning, design, construction, maintenance, etc. |
| Principal theme of research and development |
| Evaluating and foreseeing public satisfaction with infrastructure development |
| While evaluations of efficiency typified by cost-benefits analysis are now of practical use, evaluations of conformity with public needs satisfaction are also necessary. The division is, therefore, performing research to clarify the structure of public consciousness of satisfaction with infrastructure development and foresee public satisfaction with future infrastructure development. The result of this research is expected to bring us a more effective policy of infrastructure development.. |
| Research on public involvement and consensus building in infrastructure development |
| Recently, public involvement (PI) and co nsensus building in the infrastructure development projects have become crucial issues. Therefore, the division performs research on PI and consensus building methods extracting lessons learned from the past projects. |
| Research
on more advanced evaluation methods of Public works projects |
|
In order to enhance the effectiveness and transparency of execution of public works projects, the division is developing evaluation methods that accounts for 1) other external economy-diseconomy such as their impacts on the environment and on regional society, 2) uncertainty such as delay and increased costs of projects that are difficult to quantitatively evaluate, and 3) risk assessment of disaster prevention projects such as the effects to reduce “anxiety of possibility of disaster-affection” that are difficult to quantitatively measure. |
| Diverse bidding and contract system |
| In order that construction costs can be reduced and good quality products procured, the division is researching diverse bidding and contract system and drawing up guidelines of their selection. The guideline includes the VE at bidding stage (price competition and integrated evaluation types), performance based contract, and the design and build contract. |
| Technical proposal integrated evaluation bidding system |
| Based on standard guidelines for the technical proposal integrated evaluation bidding system issued by the central government, the division prepares handbooks (interim summarization) for specific operation methods in order that the system spreads among local governments and other owners of public works. |
| Research on the design and build contract system |
| The design and build contract system is a method of contracting both the design and construction work by a single entity. This research is a study of the specific implementation methods: change order, partial payment method and cost estimation methods. |
| Project management |
| The division studies how to introduce project management (PM) methodology at branch construction offices of the Ministry of Land, Infrastructure, and Transport. At this time, PM tool (PM support system) is being developed and examined at some offices on a trial basis. This research is expected to contribute to drawing up PM guidelines and implementation instructions for the Ministry of Land, Infrastructure, and Transport. |
| Construction management and other owners' support systems |
| The division is researching how to apply Construction management (CM) system and other owners' support systems such as advisor system (employing consultant as an advisor during design and procurement stage). The division is also monitoring a trial construction project with construction management concept. The results of the researches are expected to support local governments, which do not have enough capability of appropriate public works execution. |
| Appropriate contractor selection |
| In Japan, Designated Competitive Bidding System is usually used for most public works. In this system, owners select about 10 to 20 contractors before tendering. And the owners have a numbers of criteria for selecting contractors according to type of works, size of works, and location of works. Therefore, the division is studying measures that public works owners appropriately select the most reliable contractor using contractor evaluation database. |
| Research on evaluation methods of construction technologies |
| Under the new technology utilization system for public works projects that the Ministry of Land, Infrastructure, and Transport began operating in 2001, it is necessary to evaluate the technical feasibility, practicability, and constructability. The division is, therefore, performing research to establish comprehensive technological evaluation methods. |
