Public procurement (last 12 months)

Contracts first signed in the last 12 months.

The 12-month window is by original contract signing date: it covers contracts first signed in the period, and excludes amendments registered in the period to contracts signed earlier. Amounts are in KRW from Korea's Public Procurement Service (KONEPS). The 12-month total counts sole contracts in full and joint contracts by the supplier's share; joint contracts without a published share are counted but not summed. Multi-year contracts count only the current-period amount. Unit-price (framework) contracts are reported separately because their values are ceilings, not spend. Where KONEPS reports no total contract amount, the current-period amount is used as the total.

Aggregation Period: 2025-11-06 to 2026-11-05 (basis: original_signed_date)
12-Month Procurement Amount: KRW 651,400,000
12-Month Contract Count: 3 (Joint contracts: 0)
Unit-Price (Framework) Contracts (Reported Separately): 0 contracts | Ceiling: KRW 0
