Adapting historic buildings to new, modern forms generates not only financial benefits for developers but can also allow them to survive for future generations through proper remodelling. The variety of decision criteria related to the selection of a new function of a historic building makes this problem multidimensional. Many of these criteria are interrelated and have a non-linear nature which requires a comprehensive network-based rather than a classic hierarchical approach to conducting multi-criteria analysis. A comprehensive approach taking into account the specificity of the analysed problem was proposed. The study was supported by an example of the choice of building function as part of the adaptive reuse of a historic building located in Zakopane. The following variants have been analysed: a hostel (existing state), a five-star hotel, a folk art gallery and a conference and training centre. The final rating of alternatives indicates that the hotel best meets the adopted decision criteria.

Post-industrial areas, despite often showing immense damage and high soil contamination, equally often stand out via many positive assets, displaying immense potential. Post-industrial areas, in most cases, commemorate the modernisation and development of a country’s market in urban space. It is expressed in surviving buildings and urban complexes, many of which possess high historical and aesthetic value. We reviewed the literature, identified gaps and demonstrated that this subject is relevant and topical. Insofar as analyses of the urban and architectural structure of post-industrial heritage and assessments of their potential use appear often in the literature, we found that scholars rarely discussed redeveloping post-industrial areas via housing projects. The publications, methods and tools we discussed lacked solutions that could support decision-making in redeveloping post-industrial areas into housing while accounting for the needs and requirements of all stakeholders. Our initial study was based on an online survey performed among a group of specialist experts with close ties to the Polish construction market. Due to the specificity of decayed and degraded areas, any action taken entails high risk and requires a broad range of analyses, which are often not carried out due to said specificity. The main focus of our study was to determine the need to develop a new tool and the necessity of accounting for aspects that directly affect housing projects to be sited in post-industrial areas. As a result, we demonstrated that Polish practitioners displayed a need for a tool to be developed that could aid in decision-making and assessing the potential of redeveloping post-industrial areas into housing areas and that would account for the legal, organisational, technical and economic aspects and that of market analysis.

The article presents the use of the Mamdani fuzzy reasoning model to develop a proposal of a system controlling partnering relations in construction projects. The system input variables include: current assessments of particular partnering relation parameters, the weights of these parameters' impact on time, cost, quality and safety of implementation of construction projects, as well as the importance of these project assessment criteria for its manager. For each of the partnering relation parameters, the project's manager will receive control recommendations. Moreover, the parameter to be improved first will be indicated. The article contains a calculation example of the system's operations.

Construction projects are characterised by complexity in the technical, organisational and environmental sphere. The organisational complexity of such projects makes it necessary to manage relationships between actors who fulfil various functions. Formal organisational structures that have been developed for this purpose do not always reflect the actual relationships between construction project participants. In literature, scholars more and more often point to the need to identify and monitor such informal relationships and attempt to manage them in order to effectively carry out projects. Structural analysis of so-called self-organising networks of relationships between project participants is carried out on the basis of established structural measures by performing Social Network Analysis (SNA). In a situation when inappropriate communication between project participants relative to management staff expectations is detected, interventions meant to improve communication in such networks are possible. The goal of the article is proposing an optimisation-oriented approach to planning such interventions while taking various constraints, such as communication costs, into consideration. As a part of this optimisation, the authors proposed a method from the heuristic methods group. This solution will support decision-making in terms of intervening within an informal relationship structure. The method was presented on the example of an actual construction project involving the construction of a complex of housing buildings. the self-organising network structure was defined on the basis of a survey carried out among the project’s participants and concerned communication between them over a four-week period. As a result of the structural network analysis, abnormalities in communication between project participants were detected. The optimisation method developed by the authors pointed to possibilities of improving communication effectiveness within this network. The effects of the analysis confirmed the application potential of the method that was presented.

Extending the life cycle of heritage buildings through their adaptive reuse can ensure their survival and is concordant with the policy of sustainable development. Selecting a new form of use for heritage building adaptive reuse projects is a multidimensional process that can be significantly aided by multi-criteria decision-making approaches. In this paper, the authors have proposed a hybrid form of structural analysis, which is a formulation of a multi-criteria approach to the analysis of complementary forms of use for a complex of historical buildings, to be used during the early planning stages of adaptive reuse projects for heritage building complexes. The approach has been demonstrated on the example of the Boyen Fortress complex in Giżycko, Poland. The outcome of the analysis indicated that the highest share of floor space to be adapted should be dedicated to exhibition spaces, which is justified concerning cultural heritage benefits. This approach can be of significant aid to decision-makers during adaptive reuse project planning phases, thereby facilitating the continued survival of heritage sites.

The maintaining of good relations between the participants of a construction project and keeping the focus on the common goal - the success of the project - allow the performance of a project to be improved. The article presents the use of the Analytic Hierarchy Process (AHP) method to support the management of partnering relations during the implementation of a construction project. The article presents 18 parameters of partnering relations. These parameters were assigned to the cooperative relations between the general contractor or the company that manages the project and the four other participants: the subcontractors, the designer, the material and equipment suppliers and the investor. Four criteria were used to determine the order of the parameters that need to be improved first. These criteria are the duration, cost, quality and safety of the implementation of a construction project. The article features an AHP algorithm in which the pairwise comparisons were limited only to the criteria. Due to the large number of parameters, the article does not contain their pairwise comparisons, instead adopting an approach in which the priority vectors have been specified in a manner which takes into account the current assessments of the parameters of particular partnering relations and the weight of the impact that these parameters have on a given criterion. The results of the analysis can be treated as recommendations for the project manager. The higher the global priority of a parameter, the sooner it should be improved, as such an improvement is likely to be highly beneficial to the implementation of a construction project in terms of its duration, cost, quality and safety. The article provides an application of the AHP method presented in both its basic version and its more elaborate variant - Fuzzy AHP or FAHP. The provided example illustrates that the AHP method can be successfully adapted to supporting partnering relation management
