Whole life costing analysis is becoming much more important as long‐term building owners and clients start to demand evidence of what their costs of ownership will be. It is also becoming more important as more private companies invest in private finance initiative (PFI), public private partnership (PPP) and prime contracting (PC) projects. One of the main barriers to the successful implementation of whole life costing (WLC), is the lack of reliable and consistent data on elements of whole life cost (capital, facilities management, and disposal) and the performance of building elements and services. The objective of this paper is to discuss the development of a consistent and flexible framework for collecting whole life cost data for buildings. A description of the taxonomy of the cost breakdown structure is given. The proposed data structure will be of value to all the project team (designer, contractor, facilities manager, supplier, etc.) who might be involved in traditional procurement or PFI, PPP, and PC projects. When the cost data structure is populated, it will provide the foundation from which the whole life costs of different alternatives can be estimated and from which the risks such as the technical and financial risks related to WLC elements, operational risks, etc. associated with, PFI, PPP and PC projects can be assessed and minimised.

Due to their educational purpose, impact on users and quality of education, school buildings are vital institutions in the community, and their adequate maintenance should be mandatory. Studies conducted around the world point to specific inadequacies that occur in the school maintenance segment, however studies that examine the entire maintenance management process in detail are rare. With such studies, it is possible to observe all components of maintenance and its management in the observed buildings, it is possible to get a detailed insight into the present inadequacies and problems, and give the best possible answer to them. Observing the territory of the Republic of Croatia, it was noticed that there are no adequate databases on school building maintenance. Given all the above, this paper aims to establish a methodological framework and analyze the entire maintenance management process in Croatian schools to detect potential inadequacies, reveal problems, and identify areas for action to improve maintenance performance and carry out maintenance more efficiently. The current maintenance management process of elementary school buildings in the Primorje-Gorski Kotar County, Republic of Croatia, was examined based on the developed methodological framework. Data on the management process were collected through a questionnaire survey among school principals. The questionnaire was compiled based on an extensive literature review. Maintenance performance through management functions was investigated, namely: maintenance planning, maintenance organization, maintenance directing, and maintenance controlling. Important management factors within each of the mentioned functions were observed. The data analysis revealed specific inadequacies and problems in the maintenance process, and it was shown that maintenance management is not entirely effective. Recommendations were given to improve the current situation. In this way, it is possible to quickly and easily examine the entire management process and identify measures that need to be introduced in schools to improve their business in the maintenance segment. The developed methodological framework can be applied to schools from other areas as well as to other types of buildings.

This paper reviews the recent literature on skill and labour shortages in the labour market with special emphasis on the construction sector in the European Union Member States, foreseeing the Construction 4.0 era. The free movement of people is one of the rights of all citizens of the EU which also includes the free movement of workers. Labour shortages in the EU are expected to increase in the future due to a declining population and an ageing workforce. In order to recognize and forecast labour shortages, EU Member states use a variety of instruments but they do not answer as to whether it is possible to use migrant labour to appease those shortages. There are several systems used to classify labour shortages in the EU Member states. Most of the countries classify labour shortages in relation to different sectors or occupation groups as well as by skill levels, but in some Member States, classification is made according to the type of employment. Instruments used to measure labour shortages significantly differ from country to country. Several criteria are used for creating lists of shortage occupations and most of the criteria include demand side and supply side criteria. A majority of the Member States are facing labour and skill shortages in various sectors and the construction sector is not an exception. As total employment in the construction sector decreased, so did the share of employed migrants. Labour shortages in the construction sector can be eased by the availability of a labour supply willing to accept unqualified and low-paying jobs. The construction sector seeks low-, medium-, and high-skilled individuals and is most likely the sector where most of the incoming migrants will be working, which has an impact on the development and implementation dynamic of Construction 4.0.

This paper is part of broader research aimed at determining the relationship between energy performance and energy costs as a part of the operational and life cycle costs in school buildings in the Federation of Bosnia and Herzegovina (FBiH), as exceptionally important social and public buildings. The research was conducted by statistical analysis of data collected from documents of detailed energy audits (DEA) for 185 school buildings in FBiH in relation to construction periods. The paper analyzes the characteristics of buildings such as construction period, building envelope characteristics, climatic conditions, efficiency of installed space heating system, number of users and heating mode. The aim of this research was to determine the energy performance for the existing state and to compare them with the allowable values in accordance with the applicable legal regulations. There is a performance gap between predicted (calculated) and measured (actual) delivered energy for space heating. This research shows poor energy performance and provides a basis for developing strategies and plans to improve energy efficiency. The results of the energy performance of school buildings in the FBiH are the first step towards the development of a model for predicting energy costs.

The work of workers is still dominant in the realization of most construction projects and therefore has a great impact on the productivity of contractors and, thereby, on the sustainability of realization of the goals of contractors and clients. This article provides an overview of the results of more than 100 studies from the previous decade on the impacts of factors related to the personal attributes of workers on the productivity and performance of construction projects. Based on the reviewed literature and semi-structured interviews with experienced professionals in the construction industry, the relation between worker characteristics and other influences on labor productivity is defined and a list of worker characteristics suitable for research in Croatia is compiled. A survey of 262 workers, engineers, and managers from construction industries of Croatia’s eastern region, Slavonia and Baranja, showed that the worker characteristics that most influence labor productivity are experience and dexterity. It was also noticed, with a high correlation between the different groups of respondents, that physical strength and morale and morality of the workers were rated as highly influential, while education level was rated as the least influential. The research results are useful because they indicate the possibility of significantly improving the productivity of construction contractors by selecting workers with appropriate physical abilities and cognitive and non-cognitive skills, as well as developing a suitable system for training and motivation of employees.
