A six-storey office block worth eighteen billion rupiah. Payment comes in stages against a progress certificate that the owner and the supervising consultant both sign. Each stage is hundreds of millions the contractor has already spent.
The certificate is where projects stall, and payroll for two hundred workers is due on Friday.
Nobody is being dishonest. There is simply no record of what was assessed and when that all three parties hold identically.
Counts materials delivered to site, steel fixed, and work in progress that is paid for but not yet visible as finished structure.
Counts what can be seen standing on the day of the walk. Materials in a yard are not a floor.
Measures against the bill of quantities. This is the number the contract actually points to, and it is the one nobody recorded on the day.
The three assessments were made in the same week, on the same building, by people who all know what they are doing. Nothing reconciles them because nothing recorded them together.
What helps most is the real sequence on a project you worked on, including how long a certificate actually took.
