Abstract
Every construction project consumes a huge energy. The impact of energy consumption on environment is remarkable in developing countries. Sustainability infrastructure has become a crucial issue among decision makers, developers and designers around the world. Value Engineering program is one of method for improving project sustainability. This method present whether a decision increases or worsen the projects performance. While the goals of value engineering program are dominated by cost and time reduction. Case study is carried out on Automated People Mover System (APMS) project. APMS project, at Soekarno Hatta International Airport, is the first skytrain in Indonesia. The length of APMS track is 3.05 kilometres. The concept of a simple span bridge structure is used for APMS tracks. On APMS project, the initial design of the girder used the PC-U type with rarely-used dimensions. By using value engineering program, stakeholders decided to replace PC-U type with the PC-V type which has common dimensions in PT.WIKA BETON as a supplier. The use of PC-V type girder gains the benefit of efficiency in terms of time and cost. The production and erection time of the PC-V girder is more fast 30 days. Besides, The PC-V Girder saves production costs by 2 billion rupiah. This paper also attempts to give several recommendation for designing sustainable developments by focusing on the bridge structure as the main unit.
