Abstract Project management is primarily practitioner-oriented and loaded with many critical success factors (CSFs), and although these are well-evidenced in theory, they do not deliver as efficiently as factors of interest to project professionals during execution. The present study explores the perceptions of senior project managers (PMs) about project success, CSFs and complexity in large construction projects. Data from project practitioners were collected through semi-structured interviews and analysed using content analysis. The participants were selected with convenience sampling method given the complex understanding of the domain and included highly experienced PMs from the global community with expertise in project management. PMs perceive a small number of CSFs in contrast to the large exhaustive CSFs listed in the questionnaire surveys. Though important, traditional constraints of the Iron Triangle are considered inadequate in defining project success. Project professionals are seen as relying more on other performance indicators for defining a project as a success. They perceive complex construction projects in terms of a large number of interfaces, complex working systems and uncertainty. The findings of this paper suggest that project practitioners perceive differently about the CSFs and project success.

Abstract Public–private partnerships (PPPs) have become an effective and efficient contractual agreement between the state and the private sector for providing infrastructure services. Yet, their social acceptance and legitimacy are questionable. Communities accept such changes to their social contract with the government only if the PPPs are perceived to be legitimate as public institutions are not trusted by the communities. As a result, the disappointments and controversial underperformance of PPPs in Nigeria, like most developing countries, have been generally associated with community opposition due to any agency or competence-related failure. Hence, the need for this study. Drawing on data from two urban road PPPs in Nigeria, we identify the following three deeply internalised shared beliefs that shape a community group’s perceptions and attitudes towards an infrastructure built by PPPs in their neighbourhood: the public services should be provided for free, PPPs are created mainly to serve perceived ‘corrupt’ politicians and public institutions are not effective and efficient in service delivery. These beliefs, combined with the community’s structural power, explain why some community groups oppose (or support) infrastructure PPPs within their proximity, and the growing legitimacy challenge PPPs face. Our paper in this regard provides a guidance for designing effective and targeted community engagement strategies for PPP projects and contributed to PPP stakeholder management and mainstream stakeholder management research.

Abstract Despite the wide application of deep neural networks (DNN) models, their application over small-sized real-estate price prediction is limited due to the reduced prediction accuracy and the high-dimensionality of the dataset. This study motivates small-sized real-estate agencies to take DNN-driven decisions using the available local dataset. To improve the high-dimensionality of real-estate price datasets and thus enhance the price-prediction accuracy of a DNN model, this paper adopts principal component analysis (PCA). The PCA benefits in improving the prediction accuracy of a DNN model are threefold: dimensionality reduction, dataset transformation and localisation of influential price features. The results indicate that, through the PCA-DNN model, the transformed dataset achieves higher accuracy (90%–95%) and better generalisation ability compared with other benchmark price predictors. The spatial and building age proved to have the most impact in determining the overall real-estate price. The application of PCA not only reduces the high-dimensionality of the dataset but also enhances the quality of the encoded feature attributes. The model is beneficial in real-estate and construction applications, where the absence of medium and big datasets decreases the price-prediction accuracy.

Abstract The article is devoted to the development of a new information and communication concept – “construction management template (CMT)”. This concept changes the way knowledge management in construction is due to: taking into account the most effective modern and traditional methods of management; use of information technologies; end-to-end integration of different solutions into one information and communication tool. CMT is an information and communication model in the form of a three-dimensional parametric part of a building or structure and the associated resource schedule of works used to plan and control management, architectural, technological, operational, and economic decisions throughout the construction project. Combining different construction solutions and including management innovations, the developed information and communication concept is the latest way to manage knowledge in construction. Development of the information and communication concept CMT takes into account the use of modern software, innovative and most effective traditional methods of managing enterprises of the full investment construction cycle. The practical significance of the results lies in the development of recommendations for: finding and using efficiency reserves in construction management with the help of modern information technologies; development and use of construction management templates for knowledge management. The obtained results allowed establishing the new method of management in construction increases the accuracy and speed of management influences, while reducing the cost of management. Thus, more sustainable development of construction entrepreneurship is possible.

Abstract In the face of several uncertainties in the construction industry, conflicts and disputes seem inevitable. The aim of this systematic literature review of methodologies for prevention and resolution of conflicts was to develop an updated guidance for conflict management in the construction industry. To achieve this, we developed a novel tool termed Modified Reporting Items for Structured Reviews in Engineering and Technology (MORISE) that considered a modified tool from the original literature review method Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Three databases, ScienceDirect, Scopus, and American Society for Civil Engineers (ASCE), were searched and 61 articles were shortlisted. In terms of frequency of reasons cited as causes for disputes, payment regimes and delays rank first, followed by written agreement interpretation and changes in projects. Acceptable approaches to resolution of disputes include negotiation, arbitration, facilitation, and dispute resolution boards. This study were able to make a clear distinction between methodologies adopted by various researchers for the prevention and resolution of conflicts and show that in addition to prevention of conflicts, there are comprehensive and suitable techniques to resolve conflicts, which can be adopted in practice.

Abstract The study investigated the impact of the high volume of vehicular traffic on pilgrims and the community during the Zion Christian Church Easter weekend pilgrimage. The findings indicate that the South African transport planning approach is ossified and divorced from reality. There is a lacuna to address peak traffic challenges during the Easter weekend and the festive season. Notably, the government-led seasonal road safety campaigns, such as “Arrive Alive”, are curiously inadequate to address peak traffic and road accidents challenges in South Africa. The study employed the action research approach by collaborating with the Polokwane Local Municipality (PLM) to come up with lasting solutions to traffic congestion during the Easter weekend. The study found that the vehicular mode of transport was inadequate to cater for the mobility of pilgrims as well as other motorists during Easter weekend. The transport management framework for the PLM and a peak traffic standard were developed as part of the study recommendations. These recommendations augur a shift to transport planning in South Africa.

Abstract Building information modelling (BIM) technology has been focusing on the creation, sharing and use of a comprehensive digital twin of the facility under construction or renovation. It is believed that a more comprehensive, structured and complete model would be better. The aim of this paper and the underlying research is to reaffirm the view that the essence of information is to inform the user and that the main purpose of information models is that they are informative – that they contain the necessary information. Parsimonious information is information that is necessary but as simple as possible. Our hypothesis is that in many cases simpler models could be more useful, as they do not introduce technological barriers with the usually involved low- and medium-level contractors. One such case is the energy retrofitting of existing buildings. Many public and residential buildings with poor energy performance are located all over the world, especially in Eastern and Central Europe, as well as in China. They are an efficient target for a significant improvement in their energy performance by improving the building envelope and openings. The paper presents an economical process model for the modernisation of existing buildings. This model provides a basis for a parsimonious product model, which is currently under development. The broader objective of the research presented is to examine cases where a heavy information model may not be necessary and where a detailed process definition – as described in the BIM implementation plan and related documents – would lead to over-specification that would limit the free dynamics of a workflow.

Abstract Poor quality occurs in >80% of building projects. They can increase the cost of a building by up to 50% and can delay a project by up to 50%. This research investigated the determinants of poor quality on building on-sites. The research developed a questionnaire instrument that included 20 determinants of poor-quality buildings on construction sites based on literature and site visits. The survey forms were administered to construction sites operatives through hand delivery. A total of 80% of the respondents measured that the poor quality of buildings was caused by the 20 determinants. Poor workmanship, non-compliance with requirements/standards, inadequate site management, failure to achieve high-quality standards, and poor-quality materials/components were the major determinants of the poor quality of buildings during construction. This research provides fresh information on the causes and impact of poor quality on the performance of the building sector.

Abstract Selection of an appropriate structural system for an industrial facility is a difficult task for decision makers since it is the essential component, and it is hard to satisfy the owner's demands as well as the legal requirements. There are many conflicting preferences that have to be considered to assess the performance of the structural system alternatives. Decision support systems (DSSs) such as multi-criteria decision-making (MCDM) methods are useful in making an objective and rational choice. It is important to use MCDM methods in order to analytically evaluate different factors affecting the structural system selection. To address these challenges, the selection of the structural system of an industrial facility project in Turkey was carried out by applying Analytic Hierarchy Process (AHP) and the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) MCDM methods. Eight evaluation criteria were determined for the selection process within the scope of the study, which are project cost, project duration, project lifetime, labour and equipment requirement, recycling opportunities, resistance to environmental effects, suitability for installation and natural lighting needs. Prefabricated reinforced concrete (PRC), on-site reinforced concrete (RC) and steel structural system alternatives were evaluated according to each criterion by a survey study conducted by 193 civil engineer participants. Using the AHP and TOPSIS methods, it is determined that the most suitable alternative for industrial facilities is the steel structural framing system. The results were argued with the design team, and they confirmed that MCDM methods could be easily integrated in selecting the most appropriate structural system.

Abstract The public sector in Germany lags behind the economy in terms of projectification, i.e., the prevalence of projects and experience in applying project management. This has significant implications for realizing complex infrastructure projects in which the public sector is involved as one of the main actors. Nowadays, projectification represents a particular way of thinking about how to embrace a series of dynamic and challenging changes, design them, and implement them effectively for the benefit of society. A quantitative study of projectification in society in Germany was the starting point for our research, the results of which we compared with data from earlier studies of projectification in the economy. Using an interpretative case study drawing on insights from the Berlin Airport, we analyzed the impact of lagging projectification in the public sector in Germany on realizing infrastructure projects to propose suitable approaches. The results of this case study reveal significant effects of lagging projectification in the public sector of Germany on realizing infrastructure projects. In the case of the Berlin BER Airport, an inadequate governance system led to a 9-year delay in the completion date and a 250% overrun of costs directly attributable to the project. This could have been avoided by involving the private construction industry more collaboratively, by building on previous experiences gained, and by a more cooperative way of project planning and implementation. To guide future research, hypotheses are derived that can be used to analyze the underlying problem in greater depth and to derive recommendations for action.
