Divide steel structure engineering sub-projects

Both the "foundation and foundation" and "main structure" sub-projects include Steel structure sub-projects.

The steel structure sub-division of "foundation and foundation" is divided into five sub-projects: steel structure welding, steel structure bolting, steel structure fabrication, steel structure installation, and steel structure painting;

The steel structure sub-segment of "main structure" is divided into: welding of steel structures, connection of steel fasteners, processing of steel structure parts, installation of single-layer steel structures, installation of multi-layer and high-rise steel structures, installation of steel structures Ten sub-projects include painting, assembly of steel components, pre-assembly of steel components, installation of steel space frame structures, and profiling of metal plates.

(1) Division rules

Divisional projects generally divide unit projects into divisional projects based on the type or main parts of the project. Such as: foundation and foundation, main project, building roof, building decoration, electrical engineering, ventilation project, building water supply, drainage and heating, intelligent building, elevator and other branch projects;

(2) Sub-item rules

Generally, construction sub-items are divided according to different factors such as the construction methods used, materials used, and structural component specifications. For example, masonry engineering can be divided into brick masonry, concrete small hollow block masonry, stone masonry, filled wall masonry, reinforced brick masonry, etc. Earthwork engineering can be divided into earth excavation and earth backfilling. , surplus soil transportation and other sub-projects. The quantity of this kind of engineering entity measured in appropriate measurement units is the project quantity, and the unit price of sub-projects at different steps is the most basic unit of accounting for project cost (i.e. unit price). The cost of each sub-project is the product of the quantity and unit price of the sub-project.
