The PSC code H356 covers services related to the inspection and testing of construction and building materials. This includes laboratory analysis and quality control testing to ensure that materials used in construction projects meet specified standards and regulations. Agencies use this PSC to procure commercial testing and laboratory services that evaluate the properties and compliance of materials such as concrete, soil, asphalt, steel, and other building components. These services are critical in maintaining the safety, durability, and compliance of federally funded construction projects. H356 explicitly excludes medical and dental laboratory services, focusing strictly on construction-related materials testing and inspection. Government contracting under this PSC supports infrastructure development, maintenance, and regulatory compliance.
