SK ecoplant engages in quality diagnosis and support activities for each project so as to manage quality risks preemptively; and, especially for projects where issues have occurred and large-scale projects, we are conducting intensive diagnoses. To eliminate quality-related risks in advance, we carry out diagnosis and assessment activities at the construction phase, and conduct a quality assessment from the design adequacy, construction, and O&M perspective in order to come up with corrective measures and provide various technical solutions. We also carry out general quality management for firewall, fire partition, and fire-fighting facilities - from production to construction - to ensure customer safety, while performing quality and performance testing of indoor air quality measurement, radon management, noise measurement, and finishing materials such as insulation, windows, and doors. SK ecoplant reports the annual quality management business plan, including these activities, to the management and the Board of Directors every year.
