What you want to ask is whether it is normal for engineering labor costs to account for 35% of the project cost? Normal. According to the inquiry, China Law Network shows that. The labor cost ratio of different projects is different. Under normal circumstances, labor costs account for 20% to 25% of the project cost, machinery costs account for 3% to 5% of the project cost, and materials costs account for 60% to 70% of the project cost. As of September 4, 2023, labor costs have been rising, and labor costs have reached 35% of the total project cost, so it is normal.
