Value Engineering in The Selection of Fire Proof Facade Materials for The Transjakarta Bus Stop Building at Roundabout Hi Jakarta

The façade system is a critical element of bus stop structures, serving not only as an aesthetic feature and weather barrier but also as a key component in ensuring fire safety. However, many façade materials used in public facilities still fail to meet fire resistance standards, with some even employing flammable components. In practice, material selection often prioritizes low initial costs over long-term safety and maintenance considerations, increasing the risk of fire hazards and future expenses. This study applies the Value Engineering (VE) approach to optimize the selection of fire-resistant façade materials, balancing cost efficiency, technical performance, and safety. A case study was conducted at the strategically located Bundaran HI TransJakarta Bus Stop, which experiences high passenger traffic and demands a high level of safety. The analysis compared the original façade material—Façade Seven® ACP PE—with two alternatives: Alucobond® A2 (Alternative 1) and Seven® ACP FR (Alternative 2). Life Cycle Cost Analysis (LCCA) results show total costs of Rp 5,839,108,944 for the original material, Rp 6,409,735,117 for Alternative 1, and Rp 5,563,289,858 for Alternative 2. The use of Seven® ACP FR yields a 5% cost saving for façade works compared to the original material and reduces total project costs by 0.70%, making it the most economical option. Risk analysis further confirms the superiority of Seven® ACP FR, with LCCA costs reduced from Rp 7,471,223,369.42 to Rp 5,897,558,846.65 after risk mitigation—reflecting a 21.06% saving. These findings highlight the potential of VE to deliver safer, more cost-effective, and sustainable material solutions for public transportation infrastructure.
