Dear Netima
I'm sorry for the mistake.
The result of the investigation.
1.because the new surveyor start working inspect only 3 months.
2. the rush hour that miss survey process check light leak for urgent released gate-out.
The solution.
1. add staff surveyor to check hole light leak from 1 to 2 persons.
2. case error to will be penalties to subcontractors 1,000 baht per case.
You can be sure that we will improve the work better.
Thanks you.
