SK ecoplant engages in quality diagnosis and support activities for each project to manage quality risks preemptively; especially for projects where issues occurred and large-scale projects, we are conducting intensive diagnosis. To eliminate quality-related risks in advance, we carry out diagnosis and assessment activities at the construction phase, while a quality assessment is conducted from the design adequacy, construction, and O&M perspective to come up with corrective measures and provide various technical solutions. Also, general quality management is promoted for firewall, fire partition, and fire-fighting facilities, from production to construction, to ensure customer safety, while quality testing and performance verification is performed on 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 Board of Directors every year.
