I am a mechanical (MEP) engineer. For more than 16 years I have worked on fire protection, HVAC and plumbing projects on the design, site and commissioning side. On this site I share that experience in two forms: technical guides on NFPA, BS EN 12845, FM Global and the Turkish fire regulation (BYKHY), and iOS apps that speed up the everyday calculations of MEP engineers.
