*4.7. Highlight the Partitioned DSM and Explanations*

The partitioned DSM highlights two blocks. The first block includes seven activities such as A3, B1, A4, B2, and B3 which start from the 'establish objective' to the 'evaluate and review preliminary design'. This block represents the main process of the preliminary design. Preliminary design stipulates some design features that cannot be broken through in the detailed design and construction, such as each system's, subsystem's, and component's requirements and functions, a high-level outline of design features that meet each of these requirements, and cost estimates. In many reconstruction projects, determining the project goals clearly and making an acceptable design is not a one-time task. In repeated communication between the designer and the project owner; the project owner can gradually clarify his goals, and the designer can compile satisfactory deliverables.

The second block includes nine activities as E2, C1, C2, E3, C3, F3, F1, F2, and F4 which span broadly from 'make detailed design' to 'inspect and approve the work'. It spans from design to procurement and build and spans from design to procurement and construction. In the reconstruction environment, the interviewees think it is tough for the designer to complete the perfect design alone and deliver it to the purchaser and contractor. More improvement work in practice requires feedback from the contractor during construction. This process must be speedy and smooth. Construction control must be transformed into

active control, so it is necessary to monitor the progress every day and revise the plan and resource allocation for the next day in real-time. These feedbacks are all divided into the same block, indicating that they are closely connected and suitable for integration consideration in organizational arrangements.


**Figure 6.** The partitioned DSM of the project.

Some activities after partitioning have changed in order, D3 (evaluating contractor), E1 (building a project team), and E4 (preparing site) before D2 (tendering) and C1 (detailed design). Bidding is a test of the contractor's capability. However, the construction period will be greatly extended if the contractor and bidding are inspected after the detailed design is completed, as in the traditional delivery method. The reconstruction environment is complex and changeable. Contractors need not only sufficient technical force but also strong comprehensive management and coordination capabilities. Therefore, in order to speed up the development of the project, more capable contractors should be evaluated in advance and the contractors should get to know the conditions of the scene earlier in order to make full preparations. The bidding documents submitted by the contractor should show the organization's comprehensive capabilities for the future implementation of the project, such as the organization's ideas and technical arrangements, the handling of emergencies, and the procurement and deployment of resources.
