Location and progress
A construction system that is only a progress form will not be bought on site. The fight is two lines: physical progress versus payment progress. Material receipt without inspection, concealed work without photos and sign-off, changes without an instruction, quantities without a visum—miss one and settlement is both sides scrolling WeChat. We break the project into tasks and measure nodes; site quantities attach photos and location; material follows contract qty and inbound inspection; a change runs instruction to visum to settlement. Progress is not a weekly percentage—it matches location and quantities.
