Thailand: Bangkok Metropolitan Administration (BMA)
The Bangkok Metropolitan Administration (BMA) tracks budget and procurement information in two internal systems, MIS2 (budget planning and disbursement) and eGP BMA2 (procurement), and integrates and publishes the data at the project level through its Open Contract platform.
The publication covers procurement by the Bangkok Metropolitan Administration, the local government of Bangkok. Contracting processes cover the planning, tender, award, contract and implementation stages, linking budget allocations to procurement and disbursement.
For fiscal years 2022–2025 (B.E. 2565–2568), detailed procurement data is only partially linked and is available for some contracting processes. From fiscal year 2026 (B.E. 2569) onwards, the publisher links procurement data across all contracting processes. Multiple contracting processes can originate from the same budget allocation, so some records can appear similar without being duplicates.

Data available
A contracting process has several stages: tendering, awarding, contracting and implementation. You can learn about the contracting stages in this tutorial.
These counts are the number of JSON objects across all contracting processes. Parties, tenderers and suppliers are unique within a contracting process, but can be repeated across contracting processes. You can learn about data publication in this tutorial.

Data quality
The dataset has quality issues to take into account, notably:
- Most planning budget values are published in the non-standard
planning/budget/valuefield instead ofplanning/budget/amount, so budget analyses need to read both fields. - Most award objects are empty: of 46,248 awards, only 3,176 have an
awards/value/amount, with the remainder containing only a currency. Analyses of award values should exclude these empty objects. - Some releases contain non-unique
parties/idvalues, where the same organization appears twice with different roles (e.g. once as “tenderer” and once as “tenderer” and “supplier”) instead of once with both roles. Party-level analyses should deduplicate on identifiers.

Access data
This OCDS dataset is available for download in JSON, Excel or CSV format. You can download the data for contracting processes in a specific year or for all time.
JSON
Each contracting process is represented as one line of JSON text in the .jsonl file.
The .jsonl file is compressed using Gzip. Windows users need 7-Zip, WinRAR or WinZip to decompress the .gz file.
Excel
Each contracting process is represented as one row in the main sheet. Other sheets link to it via the main_ocid column. In general, each sheet is linked to its parent sheet via the [sheet_name]_id column.
Excel files can have at most 1,048,576 rows. If a year is missing, it had too many rows. Download the CSV files, instead.
CSV
Each contracting process is represented as one row in the main.csv file. Other files link to it via the main_ocid column. In general, each file is link to its parent file via the [file_name]_id column.
The .csv files are archived using tar and compressed using Gzip. Windows users need 7-Zip, WinRAR or WinZip to decompress the .tar.gz file.
