What is the Bid Validity Period?
The bid validity period (Bindefrist) is the timeframe during which a bidder is legally bound by the terms of their submitted offer. During this period, the bidder cannot withdraw or modify their bid, and if the contracting authority decides to award the contract to them, the bidder is obligated to perform at the quoted price and conditions. The period begins with the bid submission deadline and ends on a date specified in the tender documents.
The length of the bid validity period must be set by the contracting authority in the tender documents and should be reasonable in relation to the complexity and scope of the procurement. Excessively long validity periods place an undue burden on bidders, who must maintain their pricing, reserve capacity, and hold any financial guarantees for the duration. Common validity periods range from 30 to 60 days, though complex projects may require longer periods.
If the contracting authority cannot complete the evaluation and award process within the original validity period, it may request that bidders voluntarily extend their bids. Bidders are not obligated to agree to an extension, and their refusal cannot be held against them. If a bidder declines to extend the validity period, their bid is simply excluded from further consideration. Conversely, a bidder who withdraws their bid during the validity period without the contracting authority's consent may be subject to claims for damages.
Why It Matters for Bidders
The bid validity period has direct financial implications for bidders. During this period, bidders must maintain the capacity to perform and honor the prices quoted. In volatile market conditions, extended validity periods can expose bidders to significant cost risks if material prices, labor costs, or exchange rates change unfavorably. Bidders should factor these risks into their pricing when preparing their offers.
Bidders should also monitor the expiration of the validity period and be prepared to make strategic decisions about extensions. An extension request may indicate that the evaluation is taking longer than expected, which could suggest a complex competitive situation or procedural complications.
Legal Framework
The bid validity period is governed by Section 10a VOB/A for construction works and the general principles of the VgV and UVgO for supply and service contracts. German civil law principles on binding offers under Sections 145 to 148 BGB also apply. EU Directive 2014/24/EU does not prescribe specific validity periods but requires that all time limits be reasonable and proportionate.
