Public Procurement Contracts | Bid Participation, Qualification Screening, and Award Disputes

Most disputes at the bidding stage come down to whether the bidding notice's terms, the qualification screening criteria, or the evaluation process were applied consistently and lawfully. A company that believes it was wrongly excluded has a limited window to act.

Bid disqualification and objections to bidding notice terms

Public institutions must specify bid participation qualifications, required documents, and evaluation criteria in the bidding notice, and contracting authorities generally cannot apply standards beyond what the notice states (국가를 당사자로 하는 계약에 관한 법률 제10조 및 시행령). If a bid is disqualified for a document defect or a qualification issue, the first question is always whether the notice's requirement was clear and whether the defect was actually material. Many disqualifications are contested successfully simply by showing the notice was ambiguous or that the same standard was not applied to other bidders.

Successful bidder designation and award cancellation

Once a successful bidder is designated, a losing bidder may raise an objection or file a request for deliberation if it believes the evaluation was flawed, but these remedies typically have short filing periods measured in days from notification. Because contracting authorities have discretion in evaluating price, technical scores, and past performance under the relevant regulations, a challenge needs to identify a specific procedural or standard-application defect rather than simply disagreeing with the score. Acting within the objection period matters more here than building an exhaustive case, since the window closes quickly.

Joint ventures, subcontracting restrictions, and eligibility for participation

Companies structuring a joint supply agreement or planning subcontracting need to check the restrictions on joint contracting and mandatory subcontracting rules before submitting a bid, not after — a structure that looks fine commercially can violate the joint contract operating guidelines and taint the entire bid. Reviewing the consortium or subcontracting structure against the bidding notice and applicable guidelines before submission avoids having to unwind a defective bid later.

Public Procurement Contracts | Contract Performance, Change Orders, and Claims for Additional Payment

Disputes during performance usually center on whether a change in circumstances — added work, delayed site handover, price fluctuation, or a force majeure event — entitles the contractor to an adjustment of the contract price or deadline, and whether the contracting authority's inspection and acceptance decisions were properly made.

Contract price adjustment for price fluctuation and additional work

The Act on Contracts to Which the State is a Party allows adjustment of the contract price where prices of materials or labor fluctuate significantly, or where the scope of work changes (국가를 당사자로 하는 계약에 관한 법률 제19조 및 시행령 제64조 등). In practice, the dispute is rarely about whether adjustment is possible in principle — it is about whether the contractor properly documented and requested the adjustment within the procedure the contract and regulations require, since a late or informal request is often rejected regardless of merit.

Delay penalties (지체상금) and force majeure defenses

When a contractor misses the completion date, the contracting authority typically assesses a delay penalty calculated under the contract's delay penalty rate. Whether that penalty can be reduced or excluded depends on whether the delay was caused by the contracting authority's own default (e.g., late site handover) or by a force majeure event recognized under the contract terms — this causal link is where most delay penalty disputes are actually fought, not the existence of delay itself.

Inspection, acceptance, and payment disputes

A public institution's refusal to accept completed work or its decision to withhold part of the payment must be based on an actual defect identified through the inspection procedure set out in the contract, not on unilateral dissatisfaction. Where the contractor disputes the inspection result, documenting the condition of the deliverable at the time of inspection becomes central to any later claim for payment.

Public Procurement Contracts | Restriction on Qualification for Bidding and Other Sanctions

Restriction on qualification for bidding (부정당업자 제재) is the sanction companies fear most, because it can block participation in all public contracts nationwide for a set period. Understanding when it applies and how to respond procedurally is often more important than the underlying factual dispute.

Grounds for restriction on qualification for bidding

Contracting authorities may restrict a company's qualification to bid for a fixed period where it engages in conduct such as bid rigging, submitting false documents, breaching the contract without justification, or causing harm to the public interest in performance (국가를 당사자로 하는 계약에 관한 법률 제27조). Because the statute lists broad categories of misconduct, much of the dispute is about whether the specific facts actually fit the ground the authority cited, or whether the authority is stretching a minor issue into a serious category.

Proportionality of the sanction period

Even where some ground for restriction exists, the length of the restriction period must be set according to the severity criteria in the relevant enforcement regulations, and disproportionately long periods can be challenged separately from the underlying finding of misconduct. Prior compliance history, the degree of actual harm caused, and cooperation during the process are commonly raised factors in seeking a reduced period.

Practical effect: exclusion from bids nationwide

A restriction on qualification for bidding issued by one public institution is generally recognized across other public institutions as well, meaning a company effectively cannot participate in any public bid during the restriction period — this nationwide effect is why many companies engage a public contract lawyer in Seoul or elsewhere as soon as a sanction notice arrives, rather than waiting to see how the underlying dispute develops.
