4. Medium-pressure and above chemical, oil refining and pharmaceutical production facilities and inflammable, explosive and highly toxic medium equipment (excluding finished product warehouses and raw material warehouses).
Construction project refers to an engineering entity formed through the construction of various houses and their ancillary facilities and the installation of supporting lines, pipelines and equipment. Among them, "building" refers to projects with roofs, beams and columns, walls, foundations and internal spaces to meet the needs of people's production, life, study and public activities.
The Civil Engineering Teaching Steering Committee consists of nine professional steering committees (hereinafter referred to as professional steering committees), namely, civil engineering, building environment and energy application engineering, water supply and drainage science and engineering, building electricity and intelligence, architecture, urban and rural planning, landscape architecture, engineering management and engineering cost, real estate development and operation, and property management, which respectively correspond to civil engineering, architecture, management science and engineering (part) and business administration (part) in the undergraduate professional catalogue of colleges and universities.
