In large-scale engineering projects, which party usually builds and operates the concrete mixing plant? (Including multiple different construction firms) Why are the civil engineering and steel structure work usually carried out by the construction party, who handles both the work and the materials? unlike equipment, electrical systems, instruments, and process pipelines
Concrete mixing plants are generally built and operated by professional third parties to supply commercial concrete that meets quality standards. Concrete production stations are generally under direct supervision by the local quality inspection agency.
Civil engineering and steel structure projects adopt a turnkey approach for materials and labor for the following reasons: 1. The materials (reinforcing bars, concrete, shaped steel) are relatively standardized; the market for these materials is well-developed, their quality is relatively stable, and the prices of bulk materials are transparent； 2. The quotes provided by construction firms are relatively transparent (for labor costs, management fees, and material costs), with established standards to refer to. On the other hand, equipment, electrical systems, instruments, and process pipelines do not possess the characteristics of the aforementioned bulk materials, and it is not appropriate for the construction contractor to handle both the work and the materials.
