The paper describes research into the possibility of developing a concept for supporting decisions in planning construction projects (one of the most important stages of construction project management). The focus is on supporting decisions in selecting the type of and solution for the glass façade in the main design. Materials and types of solute-ons for a glass façade were analyzed and alternative solutions were obtained. The concept was developed in that it included relevant stakeholders in the decision-making process during the construction design. These stakeholders were the investor, architect, and construction contractor. The analysis was carried out and a hierarchical structure of objectives was formed as a goal tree. The criteria at the last hierarchical level were used to evaluate alternative solutions for the glass façade, and their weights were determined by all stakeholders using the AHP method (Analytic Hierarchy Process). Using PROME-THEE (Preference Ranking Method for Enrichment Evaluation), a comparison of alternative solutions for the glass façade was conducted and the alternatives were ranked according to the priorities for inclusion into the main design. The concept was tested by selecting a type of glass façade on a residential-commercial building in the city of Rijeka, Croatia.
