Following this, the major construction delays, cost overruns and quality factors were identified through an in-depth review of previous research works conducted in Denmark, Nigeria and Gaza Strip. The aggregate impacts of these factors were computed and compared between these countries. The results show that in the case of Denmark, the aggregate impact of the factors responsible for delay, cost overrun and poor quality was found in the impact interval between [0.60–0.80], but in the case of Gaza Strip and Nigeria, the aggregate impacts were found in the impact interval between [0.80–1.0]. This shows that construction projects in Denmark are found to be performed better relative to Nigeria and Gaza Strip.</p> </abstract>ARTICLEtrue improvement measures of the public sector for implementation of building information modeling in construction projects<abstract> <title style='display:none'>Abstract</title> <p>This study examines the capability improvement measures of the public sector client for enhancing the implementation of building information modeling (BIM) in construction project delivery. The study adopted a quantitative descriptive analysis based on primary data obtained through a structured questionnaire. A total of 198 valid questionnaires obtained from construction professionals within public sector organizations in Lagos State, Nigeria, provided primary quantitative data for the assessment. Data collected were analyzed using descriptive and inferential statistics. The findings indicated the measures to enhance the capacity of the public sector for BIM implementation including the following: team-based structure and recruitment of adequate number of staff (with mean score [MS] = 3.66), government support and involvement (MS = 3.64), government policies, adoption of process open to innovation, and investment in equipment and technology (MS = 3.60) had been considerably entrenched. However, measures that resulted in improved efficiency were limited to the following: reward system for performance (MS = 3.81), government policies, and education and training of staff (MS = 3.74), government support and involvement (MS = 3.73), and clear job description (MS = 3.71). Most of the measures with high level of impact were not necessarily those that are frequently used. On this basis, the public sector needs to differ from the status quo by adopting improvement measures that are appropriate for enhancing its capabilities for BIM in project delivery. The findings indicate implications that could enable the public sector to adjust and make necessary policies in a bid to improve BIM implementation in project delivery.</p> </abstract>ARTICLEtrue price prediction with deep neural network and principal component analysis<abstract> <title style='display:none'>Abstract</title> <p>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.</p> </abstract>ARTICLEtrue reduction of vehicular traffic during the Zion Christian Church Easter weekend pilgrimage<abstract> <title style='display:none'>Abstract</title> <p>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.</p> </abstract>ARTICLEtrue quality management practices and its impact on Indian construction projects<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Introduction</title> <p>The current competitiveness in the business arena of the construction industry has forced players to improve and optimise, forcing them to adopt the iterating process of continuous improvement that ensures the adequate quality of projects, in addition to moderating the cost and time involved in their implementation, the three of which have collectively been recognised as the primary factors causing the client's approval or disfavour in relation to a project.</p> </sec> <sec><title style='display:none'>Purpose</title> <p>The primary intention of the current study is to analyse the effects of total quality management (TQM) practices for construction projects and their impact on productivity, cost reduction, quality of service, customer satisfaction and Timeliness of Service by conceptualising a model using second-generation partial least squares (PLS) structural equation model (SEM) approach in Tamil Nadu.</p> </sec> <sec><title style='display:none'>Design/Methodology</title> <p>The primary data have been gathered through a sample survey collected from 94 respondents from Chennai, Kanchipuram, Coimbatore, Trichy, Karur and Tirunelveli districts of Tamil Nadu through the questionnaire.

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.</p> </abstract>ARTICLEtrue construction–specific extension to a standard project risk management process<abstract> <title style='display:none'>Abstract</title> <p>Project processes are affected by risks in many ways, and this is particularly true in today's highly competitive world. Construction projects usually take much longer than typical projects in other sectors. In this sector, it is important to follow some kind of standardised risk management process. There is much literature on different approaches to project risk management, and this paper reviews the most prominent sources that suggest procedures that are widely used in practice. Nevertheless, standard risk management still faces some shortcomings, and professionals call for a more sophisticated solution. This research aims to expand the general risk management process based on the frameworks of the prestigious stand-ardisation institutions and associations (mainly on Project Management Institute's (PMI's) risk management standard considering the approaches of Institute of Risk Management (IRM), National Forum for Risk Management in the Public Sector (ALARM), Association of Insurance and Risk Managers (AIRMIC) and International Organization for Standardization (ISO), as well as Association for Project Management (APM)). The suggested two new processes are justified by in-depth interviews conducted with interviewees working on large and complex construction projects, and are supported by a thorough literature review. The novelty of the research is that these two processes added to the standard processes, namely, risk analysis verification and validation and risk plan experimentation. The research expectedly improves the risk management process in the construction sector and emphasises the need to clearly articulate and communicate the organisation's risk appetite and the necessity for risk management training to employees. Therefore, the research reconfirms the concept of project risk management by the standards, and justifies the proposed new phases.</p> </abstract>ARTICLEtrue of complex organisational systems – system-theoretical confines of control<abstract> <title style='display:none'>Abstract</title> <p>The task of organisation is based on breaking up complex systems into a number of less complex subsystems where the interfaces are well-determined leading inevitably to hierarchical structures. Therewith, the principle need of precisely predefined targets regarding quality and time frames becomes necessary, which in turn enforces establishing controlling procedures. Meanwhile, it is well accepted that controlling processes are demanding resources and therewith form the cost of organisation. Rarely quantitatively regarded is, however, the need of having further resources ready to repair for detected quality deviations. This paper points out where the system-theoretical limits of control lie, based on a mathematical approach of delayed control where a second-order approximation leads to the introduction of terms of perseverance as well as of dissipative terms. On this background, delayed integral controlling meets the characteristics of a harmonic control system and also suffers it's confines determining the fundamentally limited reaction time. The focus of the article presented here is on the development of realistic scenarios of limited quality deviation situations and their relevance in the light of a fundamental criterion of stability derived from the differential equation of the harmonic control. In this context, we find evidence that partly self-determining concepts, such as e.g. maintained in lean construction, SCRUM and similar others, become favourable, if not superior, to hierarchical approaches.</p> </abstract>ARTICLEtrue process model of energy retrofit of buildings<abstract> <title style='display:none'>Abstract</title> <p>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.</p> </abstract>ARTICLEtrue structured literature review on construction conflict prevention and resolution: A modified approach for engineering<abstract> <title style='display:none'>Abstract</title> <p>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.</p> </abstract>ARTICLEtrue management by construction management template for sustainable entrepreneurship<abstract> <title style='display:none'>Abstract</title> <p>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.</p> <p>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.</p> <p>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.

Thus, more sustainable development of construction entrepreneurship is possible.</p> </abstract>ARTICLEtrue of the poor-quality practices on building construction sites in Malaysia<abstract> <title style='display:none'>Abstract</title> <p>Poor quality occurs in &gt;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.</p> </abstract>ARTICLEtrue the capabilities and benefits of AR construction use-cases: A comprehensive map<abstract> <title style='display:none'>Abstract</title> <p>The construction industry has undergone a radical transformation in its design and documentation process as it evolved from the days of the drafting board to today’s Building Information Modeling process. Despite the progress, a paradox of designing 3D in 2D space remains, calling for new visualization technologies that leverage the use of information in construction. Augmented Reality (AR) is an emerging technology that can serve as an information aggregator and a data-publishing platform, allowing users to view and interact with information while collaborating with others in real-time from remote locations. While AR holds the key to advance the construction industry, no research project has yet comprehensively investigated the holistic integration of AR in construction. Thus, this paper presents a comprehensive map that provides a holistic framework to understand the integration of AR into the construction phase. To achieve the research objective, the paper identifies and describes 23 use-cases of AR in the construction phase, nine AR capabilities, and 14 AR potential benefits. Then, four AR applications in construction are explored, where the underlying use-cases are discussed and mapped as a function of their corresponding AR capabilities and potential benefits. These AR applications provide an example to illustrate the concept behind the comprehensive map. Finally, the map is developed by outlining the relationships between the identified AR use-cases, capabilities, and potential benefits. The findings of this paper are crucial for the AR implementation roadmap as it provides industry practitioners an understanding of the capabilities and benefits of integrating AR into construction tasks.</p> </abstract>ARTICLEtrue life cycle BIM data to a facility management system using Revit Dynamo<abstract> <title style='display:none'>Abstract</title> <p>Facility management (FM) requires multidisciplinary activities, and thus has extensive information requirements. Much of that information is created during the design, construction, and commissioning phases of a project. Providing the owner of a facility with usable life cycle asset information after construction has been a challenge to the industry. Traditional methods of manually inputting data into FM systems are time consuming and error prone. Various automated approaches and workflows continue to be developed to respond to specific owner needs. This research developed a unique workflow that uses Dynamo within Revit to automatically extract asset management data from the model and export the data to a proprietary format required by the facility owner. The formatted spreadsheet allows for direct linking of the data to the owner's FM system, hence eliminating time wasted in manual data entry and avoiding missing any maintenance cycles that would result if the FM system is not populated with critical information in a timely manner. This article utilizes a case study approach to demonstrate this novel Dynamo workflow. The required case study asset data identified and captured include asset groups, their properties and attributes, and corresponding metadata. A basic three-dimensional representation of the facility and all its equipment are modeled in Revit and asset data are input to corresponding model elements. This article also describes the complexity of the owner's proprietary information needs and the resulting automated workflow that extracts and exports data from Revit into an Excel format that can directly link into the FM system.</p> </abstract>ARTICLEtrue of lagging projectification in the public sector on realizing infrastructure projects<abstract> <title style='display:none'>Abstract</title> <p>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.</p> </abstract>ARTICLEtrue state-of-the-art review of built environment information modelling (BeIM)<abstract><title style='display:none'>Abstract</title><p>Elements that constitute the built environment are vast and so are the independent systems developed to model its various aspects. Many of these systems have been developed under various assumptions and approaches to execute functions that are distinct, complementary or sometimes similar. Furthermore, these systems are ever increasing in number and often assume similar nomenclatures and acronyms, thereby exacerbating the challenges of understanding their peculiar functions, definitions and differences. The current societal demand to improve sustainability performance through collaboration as well as whole-system and through-life thinking is driving the need to integrate independent systems associated with different aspects and scales of the built environment to deliver smart solutions and services that improve the well-being of citizens. The contemporary object-oriented digitization of real-world elements appears to provide a leeway for amalgamating the modelling systems of various domains in the built environment which we termed as built environment information modelling (BeIM). These domains include architecture, engineering, construction as well as urban planning and design. Applications such as building information modelling, geographic information systems and 3D city modelling systems are now being integrated for city modelling purposes. The various works directed at integrating these systems are examined, revealing that current research efforts on integration fall into three categories: (1) data/file conversion systems, (2) semantic mapping systems and (3) the hybrid of both. The review outcome suggests that good knowledge of these domains and how their respective systems operate is vital to pursuing holistic systems integration in the built environment.</p></abstract>ARTICLEtrue of education for the development of key competencies of university graduates<abstract><title style='display:none'>Abstract</title><p>Competency-based education is a new trend in the process of teaching to support and develop the competencies of graduates.

This article is the extended version of the article entitled “Teaching <italic>Takt</italic>-Time, Flowline and Point-to-point Precedence Relations: A Peruvian Case Study,” which has been published in <italic>Procedia Engineering</italic> (Vol. 196, 2017, pages 666–673). A case study is conducted in final year students of civil engineering at the Pontifical Catholic University of Peru. The mock-up project is an educational building that has high repetitive processes in the structural works phase. First, traditional tools such as Excel spreadsheets and 2D drawings were used to teach production system design with takt-time, flowlines, and PTPPR. Second, 3D and 4D models with Revit 2016 and Navisworks 2016 were used to integrate the previous schedules with a BIM model and to identify its strengths and weaknesses. Finally, Vico Office was used for the automation of schedules and comparison of the methods in 4D and 5D. This article describes the lectures, workshops, and simulations employed, as well as the feedback from students and researchers. The success of the teaching strategy is reflected in the survey responses from students and the final perceptions of the construction management tools presented.</p></abstract>ARTICLEtrue integration of spreadsheet and project management software for cost optimal time scheduling in construction<abstract><title style='display:none'>Abstract</title><p>Successful performance and completion of construction projects highly depend on an adequate time scheduling of the project activities. On implementation of time scheduling, the execution modes of activities are most often required to be set in a manner that enables in achieving the minimum total project cost. This paper presents an approach to cost optimal time scheduling, which integrates a spreadsheet application and data transfer to project management software (PMS). At this point, the optimization problem of project time scheduling is modelled employing Microsoft Excel and solved to optimality using Solver while organization of data is dealt by macros. Thereupon, Microsoft Project software is utilized for further managing and presentation of optimized time scheduling solution. In this way, the data flow between programs is automated and possibilities of error occurrence during scheduling process are reduced to a minimum. Moreover, integration of spreadsheet and PMS for cost optimal time scheduling in construction is performed within well-known program environment that increases the possibilities of its wider use in practice. An application example is shown in this paper to demonstrate the advantages of proposed approach.</p></abstract>ARTICLEtrue
