Abstract

To save energy, according to two aspects of the Sustainable Development Goals (SDGs), namely Sustainable Urban Development (SDG 11) and Climate Change (SDG 13), concrete efforts that can be made are increasing energy efficiency and conservation, reducing greenhouse gas emissions, and strengthening resource sustainability. One of the initial efforts that can be made to increase energy efficiency and conservation is by applying Building Information Modeling (BIM) for energy simulation in building structures. One of the BIM-supporting software that can be used in energy simulations is Autodesk Revit, which functions for architectural, structural, mechanical, electrical, and plumbing (MEP) modeling, and Autodesk Green Building Studio, which is a cloud-based media for conducting simple simulations of building performance so that various aspects of its energy can be analyzed for assessment. The Green Building aspect assessment of GBCI used is the GREENSHIP Existing Building Ver1.1 parameter, taken from the Energy Efficiency and Conservation (EEC) aspect, which is a quantitative assessment and can be modeled. The results of the EEC aspect assessment using a quantitative assessment tool obtained a value of 5 points from a total maximum value of 28 points. This value indicates that the 1 Park Residence Building is a building that has not implemented Green Building and requires actions that support the sustainability aspect of the building.

Abstract

The development of infrastructure and commercial facilities in Indonesia continues to increase along with urbanization and economic growth, but delays in construction projects are still a significant problem. The Atlas Sport Club project in Pantai Indah Kapuk 2 (PIK 2) experienced delays caused by various factors, such as design changes, material delays, lack of communication, labor shortages, ineffective supervisory control, and extreme weather conditions. This research aims to identify and analyze the factors causing delays in the Atlas Sport Club project in PIK 2 and provide recommendations for mitigation strategies for similar projects in the future. Using quantitative and qualitative mixed methods, data was analyzed using validity and reliability tests and FTA (Fault Tree Analysis) and ETA (Event Tree Analysis) methods to understand the main causes and their impacts. The study found that work method error was the dominant factor with a probability of 0.8987. The five mitigations obtained from the pivotal event of the ETA method are completing the design and specifications at the beginning of the project; the financial process runs smoothly, the need for human resources that are by the needs and have good capabilities and experience; jointly reviewing work methods, initial designs at regular meetings; and finally procuring materials according to specifications.

Abstract

The construction industry plays a strategic role in developing infrastructure and facilities. However, issues such as cost overruns often lead to losses in the construction project implementation. This issue has been highlighted recently, especially in state-owned construction service companies. Rapid evaluation of cost control is crucial to mitigate potential project cost increases. This is because a cost overrun can potentially harm the company. Therefore, cost control in construction projects becomes a very important aspect and needs to be managed effectively. Currently, one of the software programs widely used in company cost management is the SAP S/4 HANA program, an Enterprise Resource Planning (ERP) application. This research aims to identify the potential of construction cost overruns. Through the data analysis conducted, this research includes analysis of cost management in construction projects, project implementation budgets, work breakdown structure (WBS), and cost breakdown structure (CBS). It presents solutions for potential cost overruns early using SAP S/4 HANA in the University XYZ building project.  The research was conducted using a literature study and a quantitative analysis method—data collection from interviews and analysis, as well as conclusions. Data processing using the SAP S/4 HANA program provides advantages in providing real-time information about the project budget conditions and enables effective and efficient decision-making. The research findings indicate that Top management support, Vendor support, User Training, and SAP S/4 HANA’s report can influence the successful implementation of SAP S/4 HANA in early detection. The analysis of the final project costs based on the SAP S/4 HANA Project System module in the University XYZ Lecture Building Project indicates a potential construction cost increase.

Abstract

The fulfillment of gas networks in industry and households continues to be developed to meet the needs of gas consumers with piping systems in households and industries so that the construction of gas transmission pipeline projects which are the main routes before being distributed to households or certain sectors continues to be carried out, this study aims to find the impact of costs when detailed engineering design of pipes based on the specifications of the pipes used compared to the basic conceptual design. The method used in this study is quantitative, involving field engineering surveys, followed by volume analysis based on work methods, and subsequently unit price analysis. The data generated by the detailed engineering design is compared with the conceptual design volume. An integrated design contractor carries out the construction of a 74-kilometer gas transmission pipeline located on the edge of toll roads and national roads, and its construction implementation. In contrast, the basic conceptual design is carried out by a consultant with an estimated volume of work to be carried out with various work methods, including the Horizontal Directional Drilling method of 5,439 meters, the Auger Boring method of 228 meters, and the Open Cut method of 68,333 meters. According to the technical specifications, the pipe material used varies in each work method, depending on the stress-strain during construction. Integrated design and build contractors are required to perform detailed detailing of conceptual design by verifying through engineering surveys to obtain the necessary volume, following the implementation method associated with using pipe materials for cost management. This study found that the influence of pipe material specifications based on work methods resulted in an 18.3% increase in costs.
