Oui. Cependant, comme mentionn\u00e9 \u00e0 l\u2019article 12 du Code de d\u00e9ontologie des architectes<\/a>, l\u2019architecte doit conclure une entente avec son client quant \u00e0 l\u2019ampleur et aux modalit\u00e9s des services suppl\u00e9mentaires, tout comme il \u00e9tait requis de le faire pour les services professionnels initiaux. Ces services suppl\u00e9mentaires doivent \u00eatre pr\u00e9sent\u00e9s au client et accept\u00e9s par celui-ci. Il est important d\u2019informer son client le plus t\u00f4t possible de tout \u00e9v\u00e8nement susceptible d\u2019entra\u00eener ou ayant entra\u00een\u00e9 des cons\u00e9quences sur le projet (art.18 CD).<\/p>\n\n\n\n

Une offre de service peut m\u00eame pr\u00e9voir des allocations pour impr\u00e9vus (banque d\u2019heures, etc.) pour autant que celles-ci soient convenues avec le client au moment de signer le contrat.<\/p>\n\n\n\n
