Evaluation of Reliability Values of the Building Safety System against Fire Hazards in the X Government Office Building in Jakarta

Fire incidents in Jakarta during the year 2015 reached 1582 cases, with 22 people dead and material losses of around IDR 377 billion Indonesian Rupiah (IDR). To minimize the risk of fire hazards in office buildings, buildings must be equipped with a reliable fire response system. This study evaluated the reliability of the building safety system against fire hazards in the X government office building in Jakarta. This is a descriptive study that evaluates fire safety systems based on DKI Jakarta Province Local Regulations, Ministry of Public Works Regulations and National Fire Protection Association (NFPA) requirements. There are four system reliability parameters in building fire safety. The first one is the completeness of site resources where the building is located/build, that is, water sources, road environment, road between buildings, and hydrant yard. The second one is means of rescue completeness, that is, exit doors, exit construction, and helicopter pad. The third one is completeness of active protection system, that is, alarm detection, light fire extinguisher, sprinkler, etc. The last one is completeness of passive protection system, that is, fire-resistance building structure, compartmentalization of space, and protection of openings. The study undertook a literature review, field observation and in-depth interviews. The X government office building considered in this study consists of 15 floors and 2 basement floors with a square area of 34,948 m 22 . The results of the study indicated the reliability value of the building safety system against fire hazards in the X government office building rate was sufficient, which is to say that it was 67.75 percent in compliance with standards. Parameters considered were completeness of site (82.5%), means of rescue (72.7%), passive protection (58.0%), and active protection (57.4%). The low value of the active protection parameter was caused by the functional failure of smoke detectors, fire alarms, sprinklers, and building hydrants. For the passive protection parameter, there were several improvements in shaft protection and dividing room compartments that need to be made to comply with the standard.
