The guidelines for information exchange processes in the context of public procurement are based on the same principles as the guidelines for exchange in general in the context of BIM, taking into account the circumstances set out in the description of the final outcome of this specification task. These guidelines for the information exchange processes to be achieved define the general principles to be achieved in the context of the application of BIM, are based on international standards (ISO 19650 and PAS 1192), analysis of the foreign situation, focus on the second level of BIM maturity. During the project implementation phase, these guidelines will be transformed into requirements tailored to specific project types, according to established criteria.

Public procurement and tenders can be carried out throughout the life cycle of a building. In general, one of the most important parts of the customer’s tender package is the builder’s (employer‘s) information requirements (EIR), which specify what information the supplier (contractor, contractor) must provide to the customer during the project. The potential supplier, in turn, must provide an initial BIM execution plan (BEP) in the context of the BIM, according to which the customer can assess the supplier’s offer. Still, the nature of public procurement is very diverse. Purchased services and works include feasibility study developer, building research contractor, building designer, building project expertise contractor, construction contractor, construction subcontractor, construction product supplier, building project execution supervision contractor, building construction supervisor, FIDIC engineer, building design manager, building construction manager, consultant, building construction BIM manager, building expert, building administrator. This means that the exact nature of the documents used in the context of BIM procurement, which are exchanged between the builder (client) and the supplier (contractor, contractor), as well as the supplier chain (subcontractors), can vary widely.

The application of BIM means that in the long run, with the same or even less public spending, more facilities will be built and maintained, as the risk of cost overruns in public infrastructure projects will be reduced, and projects will be more understandable and transparent, and stakeholders will be more involved.

The procurement guidelines define not only the criteria for assessing the most economically advantageous tender, but also the conditions for their application. For example, in the case of a specific project, the application of BIM requires the definition of this information model and the requirements that meet the management needs of the purchaser of the works: standards, formats, classifications against which BIM is developed and/or supplemented.

The development of BIM requires normative documents, a national set of construction information classifications, methodological documents for public procurement, standard contract forms, methodology for assessing and monitoring the benefits provided by BIM, etc.
