How fresh the source is
The Open Contracting Partnership refreshes the BMA file about every two weeks and our copy is collected once a day
Limits
Bangkok Metropolitan Administration buyers only (not the national government and not other Thai cities). The value is the contract value, often for a month, a term or a whole budget year; it is not a unit price. Contract titles are in Thai and purchases are recognised from Thai keywords, so a contract with unusual wording is missed. Values under 1,000 baht (placeholders) and over 1 billion baht (entry errors) are left out. Aggregates only; suppliers and officials are never named or read.
Rule
A figure built from records is shown only when at least 5 records sit behind it; official statistics are shown as such, with their reference period. See how we earn trust and the method.
