Schedule Risks Identification of Design Build Projects Procurement in the Development of Core Governmental Area of the New National Capital in Indonesia

The rapid execution time and the immediate necessity of the infrastructure are the reasons why many projects in the Core Governmental Area utilize the design and build method for construction in the new capital city, Nusantara. However, delays frequently occur during implementation. This thesis explores the risk factors affecting the project execution time of design and build projects. Variables were compiled from secondary data and literature studies, validated by experts, and questionnaires were distributed to respondents. These were then evaluated using qualitative risk analysis. From the 100 risk factors surveyed, 16 were identified as the most critical: (X5) (X6) inaccurate cost estimation during the planning phase, (X8) changes in urban planning, (X9) (X47) inadequate site investigation/unexpected ground/surface conditions, (X26) financial feasibility of the contractor, (X54) (X56) delayed delivery of construction equipment and materials, (X55) (X75) difficult/limited site access including weather-related factors, (X57) (X59) scarcity of labor and construction materials, (X61) (X63) design or scope changes during implementation at the owner's request, (X62) complexity and large project size, and (X70) unacquired land.
