While project risks are generally acknowledged merely from owner and contractor perspectives, other parties also play important roles in the project. The aim of this study is to analyze the application of risk management in the toll road project from stakeholders’ perception, such as contractor, owner, design consultant, supervisory consultant, and community surrounding the project. Data of risk factors were collected through interviews with each stakeholder, including the probability of occurrence and their impacts. Risk Breakdown Structure (RBS) has been adapted to breakdown project risks from various stakeholders. Risk level of each risk factor is obtained by multiplying the probability and the impact. The overall results of risk analysis show various risks as perceived by each stakeholder due to different roles and interests in the project. This research provides an understanding of how project risks need to be fully comprehended for the success of the project.
To sustainably eradicate corruption, extraordinary efforts are needed particularly in the context of construction projects. In this study, the state losses in government-funded construction projects in Indonesia is analyzed. Research data were collected through field observations for types of work that were not completed per technical specifications. Data analysis was performed using descriptive statistics. The results indicate that structural work was responsible for 98.70% of total state losses. The top three state losses were found to be associated with concrete, roads, and front stonework, and the values are 40.40%, 28.43%, and 18.23% respectively. Loss in architectural work was the smallest (1.30%). The outcomes of this survey offer a knowledge basis for law enforcement authorities and construction project supervisors to pay more attention to projects involving concrete structures, rigid pavement structures during road construction, and stonework.
The lean construction frameworks have been developed for years to enhance the poor performance of Indonesian project delivery system which influenced by the waste of non-value adding activities. Never the less most of the developments were limited on working process and lack in people empowerment. Toyota Way which integrate working process optimization and people empowerment, was developed as a lean construction frame works. This paper aimed to assess the implementation of Toyota Way principles in project delivery system by observing project’s delivery current state (status quo). The assessment began by conducting a questionnaire survey about Toyota Way implementation which then validated by interview with involved stakeholders and field observation. The assessment showed that project’s stakeholders were still unfamiliar with Toyota Way concept. Although some Toyota Way guidelines have been used in projects completion process such as visual management and training program, it found that those guidelines had not fully implemented. The project delivery system was lack of process focus and concerns more on relationship inter-parties. It also found thatToyota Way implementation will constrained by the difficulties to change the status quo of project delivery. Moreover, it seems that construction projects need practical guidelines to simplify the Toyota Way implementation in project delivery system such as project flow evaluation and system of reflection.
Constructability is the integration of expertise for the planning and designing process of a project. Constrcutabilty implementation better starts from planning phase; therefore, this phase has major influence for the whole project. This research is aimed to evaluate the constructability implementation on design bid build project and design and build system. The research method is qualitative and quantitative approach; qualitative approach applied to learn things that influence the construction implementation evaluation, meanwhile, quantitative method is applied to receive analysis from each level of constructability implementation of the project. Researcher evaluates the constructability implementation on the designated building project including the research on constructability implementation phases, projects’s life cycles, and the stakeholder’s roles. The overall average value received from the constructability implementation on Universitas Diponegoro Building project is 2.44, and for the overall average value of private Apartment project is 3.03. The result received from the two designated project is that the private apartment project generated a better value compare to the Universitas Diponegoro Building project. The project life cycles also show that the private apartment building project was able to optimize the execution time by using the constructability and the design also more constructable.
