Federal Act
on Public Procurement
(PPA)

¹ The con­tract­ing au­thor­ity veri­fies the tenders re­ceived for com­pli­ance with the form­al re­quire­ments. It cor­rects any ob­vi­ous cal­cu­la­tion er­rors.

² The con­tract­ing au­thor­ity may re­quire ten­der­ers to ex­plain their tenders. It keeps a writ­ten re­cord of the re­quest and the an­swers.

³ If a tender is re­ceived with a total price that ap­pears un­usu­ally low in com­par­is­on with the oth­er tenders, the con­tract­ing au­thor­ity must ob­tain ap­pro­pri­ate in­form­a­tion from the ten­der­er as to wheth­er the par­ti­cip­a­tion con­di­tions have been com­plied with and wheth­er the oth­er re­quire­ments of the in­vit­a­tion to tender have been un­der­stood.

⁴ If sup­ply and price tenders must be sub­mit­ted in two sep­ar­ate en­vel­opes, the award­ing of­fice first pre­pares a rank­ing ac­cord­ing to the qual­ity of the tenders. In a second step, it eval­u­ates the total prices.
