Design of Sustainable Construction Through Value Engineering of an Automated People Mover System Project

Sustainability infrastructure has become a crucial issue among decision-makers, developers, contractors, and consultants around the world. Value Engineering (VE) program is a method for improving project sustainability. This method present whether a decision increased or worsens the project's performance. The purpose of this study to create and evaluate alternative ideas for expanding the project value. This study proposes VE analysis at the design level to achieve optimal project costs and duration. The case study is carried out on the Automated People Mover System (APMS) project. APMS project, at Soekarno Hatta International Airport, is the first Sky train in Indonesia. The length of the APMS track is 3.05 kilometres. APMS tracks are using for a simple pan bridge structure. On the APMS project, the initial design of the girder used the PC-U type with rarely-used dimensions. By using the VE program, stakeholders decided to replace PC-U type with the PC-V type, which has standard dimensions in PT. WIKA BETON as a supplier. The use of a PC-V type girder gains the benefit of efficiency in terms of time and cost. The percentage of production and erection time of the PC-V girder is 97% faster. Besides, the percentage of cost-saving is 9% of the total project cost.
