This thesis is situated within the field of architectural practice, at the intersection of architectural design, project-economic parameters, and multicriteria evaluation tools. Its primary focus is to investigate the relationship between the digital BIM model, Bills of Quantities and Costs (BoQ), and the assessment of alternative design solutions.

Within this context, the thesis proposes a methodological framework that integrates Building Information Modeling (BIM), the Bill of Quantities (BoQ), and multicriteria decision analysis (MCDA) through the Analytic Network Process (ANP) method. BIM serves as the foundational digital environment for the project, BoQ functions as the mechanism for measurement and economic representation, while ANP provides a means to synthesize both quantitative and qualitative data, as well as expert-driven directions, into a unified evaluation framework. The selection of ANP is justified by its capacity to capture interdependencies among criteria—a critical aspect in architectural problems, where form, technical rationale, maintenance, cost, and future potential are inherently interconnected.

The research unfolds along two principal axes. The first is a systematic literature review (SLR), which examines the application of MCDA methods in architectural and construction design, with emphasis on the types of criteria, stages of implementation, and the integration of qualitative and quantitative data. The second axis focuses on the synthesis of the proposed methodology and its application to an architectural case study, specifically the selection of a façade system for a six-storey office building.

The aim is to investigate how BIM, the BoQ, and ANP can operate in combination as a design support tool, strengthening the documentation and coherence of the decision-making process.
