5 evidence groups for explaining an unusually low bid

An unusually low bid should be explained using the actual project, cost evidence, organisation and any relevant support. France and Switzerland have distinct procurement procedures for the authority's enquiry. A low figure is not itself a completed legal finding. The evidence schedule answers the questions received without inventing a mandatory profit margin or promising acceptance of the tender.

Example question

Which cost assumptions support the bid?

Julie Illustration

Match quantities, time, supplies and subcontracting. An attractive price alone does not establish manifest undervaluation under L2152-5.

Does Switzerland use an automatic low-price percentage?

The law

Which official provision helps explain this situation?

Une offre anormalement basse est une offre dont le prix est manifestement sous-évalué et de nature à compromettre la bonne exécution du marché.

Code de la commande publique art. L2152-5In force since 1 April 2019Read on Légifrance

In plain English: No such threshold is established here. LMP 38(3) concerns enquiries about unusually low total price;44(2)(c) addresses specified failure to substantiate compliance and reliable performance.

Answer

Should subcontracted costs be omitted?

No. Include relevant subcontracted scope in the explanation. Outsourcing does not make those costs irrelevant.

Answer

Can the explanation become a replacement bid?

A request does not automatically grant repricing or negotiation. Answer the actual questions without assuming permission to alter the tender.

Answer

What does the justification file deliver?

It links request, costs, resources and records. It certifies no viability and guarantees no acceptance.
