summary:The main means of communication during the pre-design phase is natural language. Effective communication during the pre-design phase through text documents and reports is essential to the success of a design and construction project. The study develops and evaluates a Natural Language Processing (NLP) tool called ArchiBERTo to process textual data related to design tender documents in the Italian public procurement process. Documenti di Indirizzo alla Progettazione (DIPs) are key documents, as they outline the demands, needs, and objectives of the public appointing party. ArchiBERTo is developed to process and convert DIP quality objective sentences into a hierarchy of objectives and criteria. The performances are evaluated by comparing the tool’s rankings with those provided by a group of domain experts. The results demonstrate ArchiBERTo's capability to reflect the collective ability of a panel of experts and to properly reflect the different contents of the DIP in the objectives hierarchy. The proposed system aims to address the issue of information asymmetry and potential misunderstandings, or varying interpretations, among the key actors of the Italian tendering procedure, namely the public appointing party, the design teams, and the external committee, regarding the relative importance of quality objectives and evaluation criteria. The utilization of the NLP systems ArchiBERTo to establish a shared hierarchy of objectives is expected to enhance communication and promote consensus during the pre-design phase. The minimization of the consensus issue among the actors can have a positive impact on the overall quality of the design proposals and facilitate the evaluation process conducted by the external committee, bridging the gap between expected and actual quality, ensuring that design proposals align with the quality objectives and demands of the public actor.
