A Korean fire-engineering firm (주식회사 페스텍) whose name stands for Fire Engineering & Science Technology, offering simulation-based fire-impact assessment, domestic and international fire-code analysis, fire-case investigation and performance-based design (성능위주설계), alongside fire design, supervision and construction. It also runs a fire-test-equipment arm, so it is a hybrid engineering/technology firm rather than a pure PBD consultancy. Analysis aids professional judgement.
