Currently, BIM implementation in domestic FAB construction projects is in such an early stage that they are benchmarking the BIM implementation method applied in the conventional building sector. As such, in order to enhance the usability of BIM in FAB construction projects, it is necessary to have a correct understanding of FAB construction and to apply BIM in accordance with the characteristics of FAB. This requires defining critical BIM competencies needed by the participants of FAB construction projects in undertaking their tasks as well as identifying their current level of competency possessed. Accordingly, this study defined and presented BIM competencies that reflect the characteristics of FAB through the analysis of typical tasks related to FAB construction projects. For this, project participants from three FAB construction project sites in Korea (where BIM was implemented) were recruited, and a survey was conducted on their status of competency level. Moreover, a comparative analysis was conducted focusing on the correlations between their career characteristics (‘Construction project experience’, ‘BIM-based construction project experience’, ‘FAB construction project experience’, ‘BIM-based FAB construction project experience’ and ‘Overall project experiences’) and their current level of BIM competencies. As a result, high correlations were found between BIM competencies and BIM-based FAB construction project experience for the owner group, whereas competency items related to BIM-based construction project experience showed high correlations for the designer group.

Construction Project Scheduling

Prefabricated buildings are the direction of the future development of the construction industry and have received widespread attention. The effective execution of prefabricated construction project scheduling should consider resource constraints and the supply arrangement of prefabricated components. However, the traditional construction resource-constrained project scheduling implementation method cannot simultaneously consider the characteristics of the linkage between component production and on-site assembly construction. It cannot also fully adapt to the scheduling implementation method of the prefabricated construction projects. It is difficult to work out a reasonable project schedule and resource allocation table. In order to determine the relevant schedule parameters that can reflect the actual construction situation of the prefabricated building and meet the scheduling requirements of the prefabricated project, this study proposes a prefabricated construction project scheduling model that considers project resource constraints and prefabricated component supply constraints. Additionally, it improves the design of traditional genetic algorithms (GAs). Research results of the experimental calculation and engineering application show that the proposed project scheduling optimization model and GA are effective and practical, which can help project managers in effectively formulating prefabricated construction project scheduling plans, reasonably allocating resources, reducing completion time, and improving project performance.

Additional Information

Among the recent data mining techniques available, the boosting approach has attracted a great deal of attention because of its effective learning algorithm and strong boundaries in terms of its generalization performance. However, the boosting approach has yet to be used in regression problems within the construction domain, including cost estimations, but has been actively utilized in other domains. Therefore, a boosting regression tree (BRT) is applied to cost estimations at the early stage of a construction project to examine the applicability of the boosting approach to a regression problem within the construction domain. To evaluate the performance of the BRT model, its performance was compared with that of a neural network (NN) model, which has been proven to have a high performance in cost estimation domains. The BRT model has shown results similar to those of NN model using 234 actual cost datasets of a building construction project. In addition, the BRT model can provide additional information such as the importance plot and structure model, which can support estimators in comprehending the decision making process. Consequently, the boosting approach has potential applicability in preliminary cost estimations in a building construction project.

Many interfaces typically exist in the construction phase of a project. Since project participants usually fail to share interface information, most interfaces are difficult to solve effectively during that phase. Furthermore, future activities might not be implemented based on changes made by predecessors. In practice, failure to manage interfaces may result in additional work or in low project performance. In order to manage construction interfaces effectively, this study proposes the novel Multilevel Interface (MI) Matrix approach to enhance interface management during the construction phase of construction projects. By using the MI matrix approach, construction interface issues will be tracked and man-aged easily and effectively. Furthermore, this study develops a construction web matrix-based interface management (WMIM) system integrated with the proposed MI Matrix approach. The MI matrix approach and WMIM system are applied to a pilot test to illustrate how to support interface management during the construction project. As results of the pilot test indicate, the MI matrix approach and WMIM system provide an effective interface management tool for the construction phase. Santrauka Statybos projekto statybos darbų etapui būdinga tai, kad su įvairiais subjektais palaikoma gausybė ryšių. Daugumą jų šiame etape veiksmingai palaikyti dažniausiai ne itin lengva, nes projekto dalyviai paprastai informacija apie juos nesidalija. Be to, perimantys darbą gali ir nesiremti savo pirmtakų padarytais pakeitimais. Praktine prasme nesugebant valdyti ryšių, gali tekti darbus perdaryti arba projekto efektyvumas gali sumažėti. Efektyviam su statyba susijusių ryšių valdymui šiame darbe siūlomas novatoriškas įvairialygių ryšių (ĮR) matricos metodas, leidžiantis pagerinti ryšių valdymą statybos projekto statybos darbų etape.

Abstract 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.

The acceptable level of quality in construction projects has long been a problem. Significant resources are wasted on construction projects because of inefficient or non-existent quality management procedures. Therefore, this study evaluates the quality management and the quality grading practices in the construction project with emphasis on the Covenant University Sports Complex. The quantitative research strategy and questionnaire survey were used as the main data collection instrument for soliciting information from the project participants in order to determine the best key for quality management practice. Moreover, an ultrasonic pulse velocity tester was engaged to assess and evaluate the conditions of concrete structural members. It was found out that management commitment to quality is the most key for effective quality management practices in the construction project. In addition, the ultrasonic pulse velocity (UPV) test carried out on the randomly selected structural members varied in the range 4.2km/sec to 4.6km/sec. From this, it is inferred that the quality grading and homogeneity of concrete in the tested reinforced concrete columns, beams and slabs fall in the range of "good to excellent concrete". The findings would assist project participants in implementing an efficient quality grading and management while executing construction projects.

Project Data

A BIM-enabled Construction Project (BIMCP) refers to a project involving relevant BIM tools to generate, exchange and manage project data between project participants. Success in delivering BIMCPs largely relies on how effective project members collaborate. As a result, collaboration on BIMCP has become a growing field of research while a review of studies on collaboration on BIMCPs is still missing. To address this gap, this paper presents the findings of a systematic review on studies devoted to collaboration on BIMCPs over the past 10 years (2006-2016). To this end, 208 studies published in 12 ICT-oriented journals in the construction context are thoroughly reviewed. The findings bring to light that studies on collaboration on BIMCPs are sporadic, isolated and focus on narrowed, limited and disjointed areas associated with collaboration. The study contributes to the field through highlighting the gaps of the existing literature on the topic. This provides a stepping stone to direct future inquiries that target collaboration on BIMCPs.

Purpose Cultural differences cause conflicts amongst construction project participants, deterring the success of projects. Understanding such different cultural manifestations could help the removal of the misunderstandings amongst sub-cultural groups and removal of formal irrationalities deterring the progress of construction projects. The purpose of this paper is to explore the nature of project cultures in the public sector construction projects. Design/methodology/approach An exploratory case study was selected as the research strategy to achieve the research aim. Three public sector building construction projects were used as case studies. Nine semi-structured interviews and observation of two progress review meetings per case were used for data collection. Findings As per the research findings, contractors believed that construction project culture emerged and transferred through continuous interactions and socialisations with time. Consultants believed that culture was emerged focusing on clearly defined project objectives. In addition, all members assumed that project members at high authority levels were contributing more for the emergence and transfer of cultural aspects. Levels of culture and power existed within the public sector project culture as clients with the highest power, consultants the next and contractors with the least power. Public sector project culture was not leader centred. Shared behavioural norms were not much popular in project culture. Highly differentiated behavioural norms, demonstrating clear professional sub-cultures for the client, contractor and consultant, were available. Originality/value The research findings are helpful to construction project managers to enhance the level of motivation, productivity, commitment, continuous interactions and socialisations of project participants and to avoid any negative outcomes in behaviours.

The Impact

The objective of this paper is to analyse communication and information flow within construction projects on the basis of a survey study and a review of the literature. The subject of communication and its impact on carrying out a construction project is widely discussed in global academic literature. Many scholars point to problems with communication and information flow while also reporting that it directly affects construction project time and cost. In the literature, communication is also presented as an essential factor that improves safety and partnering in construction projects. There is also a group of studies that points to the lack of effective communication as the cause of delays and modifications. The authors, in reference to global studies, present the results of a survey study performed in Poland on a group of 160 construction industry practitioners. Information about five research areas was collected. These areas included: general information about communication and information flow between construction project participants, problems in carrying out construction projects in relation to the lack of effective communication, the impact of communication on the success of carrying out a construction project, communication costs, and the need to develop a tool (a digital system) that would support construction project managers in the optimal control over communication between project participants. On the basis of the obtained research results and the literature study, it was found that effective communication and information flow within a construction project can improve the construction process and that there exists a need to develop a comprehensive approach that would aid construction project managers in ensuring a more effective information flow.

Hierarchy Process

For several decades, the number of reported accidents and fatal incidents in the construction industry has remained high compared to those in other industries. Therefore, many studies have been conducted in an effort to reduce accidents and fatal incidents in the construction industry. Recently, construction safety management has shifted from the construction phase to the pre-construction phase, ultimately to eliminate fatal incidents. In line with this change, South Korea enacted the Design for Safety (DfS) process in 2016. However, the current DfS process remains not well implemented for several reasons. Therefore, this study aims to present eight alternatives to improve the DfS process and suggests DfS improvement priorities by considering construction project participants and career levels using what is known as a fuzzy-analytical hierarchy process (F-AHP) analysis. The results of this study are as follows. First, respondents overall suggested improvements in the area of ‘assignment of responsibility for DfS to the client’ (0.196). Second, improvement priorities were also identified according to construction project participants and career levels. The results of the study can be utilized as basic information for DfS improvements during construction projects.
