Projects of common interest are projects serving the implementation of priority corridors and areas of energy infrastructure, mainly trans-European electricity, gas and oil transmission networks in order to reduce the European Union’s energy dependence. They also help strengthen the energy security of individual countries, including Poland. The article aims at reviewing projects and assessing an impact on domestic markets in the context of the challenges of the fuel and energy sector in Poland. The article is an analytical study, in the “desk research” formula. Research methods used during the elaboration of the research include the analysis of national and EU strategic documents and the subject matter of energy security. In order to evaluate the impact of the implementation of projects of common interest on a variety of supplies of a member country (Poland), an exemplary assessment of the diversification status is presented using Hirschman-Herfindahl concentration index for gas supplies.

The productivity of real property depends on the efficiency of the property management technique. Building Information Modelling (BIM) is an emerging technique examined. The aim of the research is to explore the practicability of BIM for the management of public buildings (PBs) and the hindrances subject to the effective operation. The tasks of the research were to investigate the awareness level of BIM for management of PBs; to investigate the acceptance level of BIM as a property management technique; to explore the hindrances of BIM use for the management of PBs; and, to assess the suitability of BIM for management of historic buildings. Survey and descriptive methods were used in the research. One hundred and nine questionnaires were distributed and a total of seventy-eight was returned. Purposive sampling technique was used for the selection of the respondents. Stratified random sampling was used to select the public buildings, while clustered sampling was used for locations. The findings of the research showed a low level of awareness from the respondents; BIM was not in use; the acceptance of BIM was high but the hindrances were numerous. The research concluded that the use of BIM was practicable given adequate awareness and training. The research recommended a paradigm shift from the traditional property management approach to BIM strategy for the effective performance of PBs.
The construction industry is one of the most important activities that contributes towards the economic growth of any nation. However, the sector has been experiencing problems of cost and time overruns, particularly the problems are significant for the lowest-bid awarded construction projects in the developing countries where inappropriate planning is reported to be one of the major causes. Thus, the paper aims at developing an integrated scheduling approach for construction projects during the planning phase from a project owner’s perspective. The proposed approach integrates cost estimation and schedule in light of practical activity precedence and mathematical cost optimization using different project commencement dates. The study has shown that cost and time optimization model could yield impractical results unless double precedence relations (start-to-start plus finish-to-finish) are imposed between some activities such as trench excavation and pipe laying. It has also demonstrated that the cost and time budgeted during the planning phase would substantially deviate from actual if the planned construction start date slips from the plan, particularly for short period projects. The proposed approach demonstrated in the paper can sufficiently allow planning engineers to develop a comprehensive construction schedule so that the cost and time overruns in the lowest-bid awarded construction projects can be reduced. The paper provides empirical insights into how a robust construction schedule is developed from an owner’s perspective. Cost-time optimization and risk analysis results obtained from manual computation might reduce the reasonable accuracy of the desired cost and schedule integration unless each activity is assigned its own calendar.

The goal of the article is to show how bankruptcy of an enterprise appears. Therefore, the generalised balance equation of financial and economic activity of the enterprise is considered. Graphs of two main characteristics of risk management are given. The conditions under which the income and expense curves can re-intersect are given. From this moment the bankruptcy procedure of the enterprise begins. There are four stages through which the company must pass until it is declared bankrupt. It is also indicated how zones of permissible, critical and catastrophic risks arise. On the basis of business speed and investment profitability, a table of SWOT analysis of financial improvements of the enterprise is built. Four strategies of economic security and possible risks are also considered. An example of one of the methods of financial recovery of the enterprise using intermediate risky activities is given. By means of calculations it is shown that long participation in risky business, can bring both the considerable income, and lead to almost complete loss of the capital. The conclusion is made: it is necessary to leave risky business in time.

Creativity is an important component of the economy for modern cities, and necessary condition for it is the qualitative understanding of the economic theory science. In the global competition, it plays an important role for the economic growth dynamics, which is directly related to human resource role in the modern economy. The competitiveness of the territories depends on their attractiveness to economically active individuals and the opportunities they provide with economic growth. When considering the creative and cultural industries as potential economic development factors in the urban economy, culture can be considered as a new stage in urban development based on quality of life, creativity, which provide a level of degree for balance and determine the stability of the growth potential. The development of supporting urban infrastructure is identified as one of the drivers for expansion of the cultural and recreational domains both for the political and economic development. They reflect the specific characteristics of each city, the competitiveness versus attractiveness potential, and demonstrate the potential shift from the environment for production to a potentially new consumer environment with a higher “symbolic value”. The creative industries today can serve as an urban development domain tool, creating a modern approach to economic activity in various sectors of the economy. The authors draw attention to the cluster link between creative and cultural industries in urban planning. The authors propose a methodology for assessing revenues and costs, as well as recommendations for the work of cultural organisations and institutions involved in creating a creative urban environment. The article presents data and modelling results of the economic impact calculations for two imagined cities in order to theoretically approbate the methodology, which would help assess the socio-economic effect of the development of certain clusters. The aim of the research is to identify the impact of culture and creativity on the economy of city. The calculated information for decision makers would help formulate recommendations, evaluate potential developments of the urban environment, assist in planning and networking in urban agglomerations, based on clusters of creative and cultural industries, as the post-industrial city needs to make changes in order to achieve economic growth. The development of urban cluster of creative and cultural industries has a certain multiplicative effect, i.e., impact on the development of other types of economic activity.

The atmospheric CO2 is now at the highest level seen (400 ppm) and the construction sector is responsible for 36 % of all greenhouse gases. One way to reduce this negative impact is to use more sustainable and environmentally friendly materials such as timber in the construction. To direct the sector towards this goal, the Erasmus+ project HiTimber (“Sustainable High-Rise Buildings Designed and Constructed in Timber”) was initiated in 2017. With the objective of developing an international and trans-disciplinary course in design, construction and management of sustainable high-rise timber buildings, project-based learning (PBL) was applied. The aim of the paper is to examine the effects of the PBL by examples and results from the HiTimber workshops. The presented results are the approbation of scientifically-practical results, derived from surveys conducted in 2018 and 2019 where 29 teachers and 45 students evaluated the PBL-based workshops. In general, all teachers and 85 % of students were satisfied with the PBL approach; the students were more engaged, motivated and successful in their studies. However, the transition from traditional teaching to PBL has its challenges and requires time, effort and strong commitment from both students and teachers to be effective.
There is a usual positive correlation between infrastructure development and property sales, because infrastructure development has positive externalities on property sales. However, in Bulawayo this correlation is not usually present in all aspects of properties transactions. The research seeks to find out the trends in infrastructure development and property sales in the city of Bulawayo. The research also aims to unearth some of the factors other than infrastructure development that determine property values in Bulawayo’s low-density suburbs. The research took a mixed methods approach to data collection where both qualitative and quantitative methodologies were utilised. Questionnaires were administered to the people in low income areas of Pumula, Cowdrey Park and Emganwini. In depth interviews with key informants in the real estate sector were conducted to cross fertilise and enrich the inquiry. The research found out that in most cases there is a strong correlation between infrastructure development and property sales, but in some cases, this is not the case as some forces are put in play to distort the market play. The research also discovered that apart from infrastructure, property sales in Bulawayo’s low-income residential suburbs are also affected by income, supply of houses and demand for these houses. In Bulawayo, there are bottle-necks in the supply of houses and this has distorted the market because people are taking whatever there is on the market at any price. This has reduced the influence of infrastructure development on property sales.
Of recent, the need to increase the performance of services installations in buildings has been a major point of interest amongst construction professionals through the consideration of commissioning practices required to be adopted during execution of building projects. The aim of the study is to investigate awareness of building professionals on the adoption of building commissioning practices in the installation and use of building services equipment. The study therefore examines the characteristics of building commissioning practices, examines the level of awareness and adoption of building commissioning practices amongst construction professionals in Lagos State, Nigeria, as well as investigates the factors influencing their adoption. A survey method of research was employed with questionnaire administered on construction professionals available on the list of firms of the Federation of Construction Industry (FOCI) registered with the Lagos State Government. The data collected were analysed with the use of statistical tools, such as frequency distribution, mean item score, analysis of variance and factor analysis. The study shows that amongst the characteristics of building commissioning practices, lighting services have the highest level of engagement with a mean score of 4.45, heating, ventilation and air-conditioning 4.15 while vertical transporting services have a mean score of 3.82. A significant proportion of the respondents are aware of building commissioning practices through different professional training courses and practices. The study also shows that there is relationship between the level of awareness and adoption of building commissioning practices at 95 % confidence level. The indicators in group one are found through the factor analysis to be contributing mostly to the adoption of building commissioning practices by the respondents. The study concludes that with the existing level of its awareness in the study area, efforts should be made by stakeholders to entrench building commissioning practices provisions in the country’s institutional framework/regulatory code, which covers the installation and use of service items in building stock so as to further deepen their adoption in order to enhance performance and comfort of building projects.
Indian real estate segment has been one of the utmost affected segments of economy contemplating the changes in economic policies. The Indian economy experienced a radical change as an outcome of demonetization and the consequences are perceived on the real estate segment. The current study has been proposed to evaluate the efficiency of Indian real estate firms by adopting the technique of data envelopment analysis during the pre- and post-period of demonetization. The aim of the research is to understand the effect of demonetization on the performance of the Indian real estate firms during the post-demonetization period compared to pre-demonetization period. Eight real estate firms have been considered for the analysis. The firms have been ranked on the basis of the efficiency score. It is evident from the results of the study that there is a significant difference between the ranks of the firms during the period of pre and post demonetization; and it can be elucidated that the demonetization has an impact on the performance of the firms.
The study focuses on effective methods used to address resistance to business change. The aim of the study is to provide information related to methods of handling resistance to change and to present empirical results for each method that is used. In the study, the author uses quantitative methods, and more concretely, the questionnaire technique for data collection. Quantitative research methods that are used include linear regression, cross-tabulations and Pearson Chi-Square test. In this study, 399 businesses in Kosovo were involved. 64 cases of study (businesses) were excluded from the study because these businesses did not use any of the methods presented in the resistance treatment study. The results of the study show that support as a method of resistance treatment is mostly used by the businesses under consideration. The use of these methods has made the changes to be more effective in increasing revenue, providing superior organisational performance and steady market position. This study creates value for businesses, focusing on the importance of using methods for addressing resistance and the success of changes in organisations. However, in reality many initiatives for change fail in achieving their objectives. This fact promotes the interest in recognising those factors that influence the successful implementation of change efforts in organisations.
