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.

The construction industry is deemed to be one of the most dangerous industries worldwide due to its special characteristics of production process. Globalization has brought about an increasing number of construction companies involving themselves in the international construction market. Due to involvement of participants from different countries and regions, international construction projects possess complexities from national, organizational and individual perspectives which may affect construction safety management adversely and lead to unsatisfactory safety performance. Safety climate, defined as “a unified set of cognitions regarding the safety aspects of the organization”, is often considered to be a predictor of safety behavior and performance. After conducting a comprehensive review of existing literature related to safety climate measurement in construction sector, this study highlights several conditions for selecting suitable safety climate instruments specific in international construction projects.

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. Taikant ĮR matricos metodą lengva veiksmingai sekti ir valdyti statybų ryšių klausimus. Be to, atliekant tyrimą sukuriama projekto dalyviams skirta internetinė matricinė statybų ryšių valdymo (WMIM) sistema, į kurią įtrauktas siūlomas ĮR matricos metodas. Taip pat, taikant ĮR matricos metodą ir WMIM sistemą, atliekamas bandymas, rodantis, kaip jie padeda valdyti statybos projekto ryšius. Bandymo rezultatai rodo, kad ĮR matricos metodas ir WMIM sistema – tai efektyvi ryšių valdymo priemonė statybos darbų etape.

Since the reform and opening up, Chinese economic and social development has undergone great changes, and the people’s living standards have improved markedly. For the national economy, the engineering construction is not only a carrier for specific economic tasks, but also a driving force for rapid and sustained economic development. With the continuous expansion of the scale of construction projects, safety management problems of construction projects are constantly exposed. How to effectively avoid accidents has become an important issue to be solved urgently in the construction industry. This paper mainly evaluates human factors in the process of construction project management, such as workers’ proficiency, workers’ safety awareness, technical workers’ quality, and workers’ emergency capacity, with the purpose of helping China’s construction projects proceed smoothly. In this research, we provide a multiple attribute group decision-making (MAGDM) technique based on Pythagorean 2-tuple linguistic numbers (P2TLNs) and the VIseKriterijumska Optimizacija I KOmpromisno Resenje (VIKOR) method for evaluating the human factors of construction projects. P2TLNs are used to represent the performance assessments of decision makers. Relying on a P2TLWA operator, P2TLWG operator, and the essential VIKOR method, a general framework is established. An application is presented to test the validity of the new method, and a comparative analysis with two algorithms and the P2TL-TODIM method is illustrated with detail.

PurposeIt is well recognized that the construction industry is characterised by inefficient and ineffective service delivery due to various causative factors. Thus this study aims to examine the influential factors affecting public construction project performance in Ethiopia to improve the industry's service delivery.Design/methodology/approachFrom the extensive literature reviewed, 58 potential factors affecting construction project performance have been compiled. Based on the evidence accumulated, the conceptual model of this paper has been developed. By using survey questionnaires, valuable data were collected from the construction industry professionals in Ethiopia; analysed and interpreted with the use of both SPSS and AMOS software.FindingsIt is concluded that failure factors related to the “performance” of the contractor, the “capability” of the owner, the “project design-procurement process,” and project contract management can significantly contribute to the poor performance of public construction projects in Ethiopia. Ten key factors include inadequate contractor capacity, weak project site management and supervision, weak project management skills and capabilities of the owner, additional work orders, delayed payment, lack of comprehensive project plans between parties and incomplete project design, rising material prices, ineffective project schedules, and cost management, rising market prices and devaluation of the currency.Research limitations/implicationsThe scope of this study confined to public projects in Ethiopia. It suggests that further research needs to consider public and private construction from a comprehensive perspective in the developing countries.Practical implicationsIt provides practitioners with information and guidance on the factors that affect the performance of construction projects.Originality/valueIt provides inclusive evidence related to many factors that affect the performance of public construction projects.

AbstractOne of the key problems in managing the realization of a construction project is the selection of appropriate working crews and coordinating their activities in a way that ensures the highest degree of implementation of defined goals (minimizing the project duration and/or reducing downtime and related costs). Most of the existing methods of work harmonization used in construction industry allow obtaining the desired results only in relation to the organization of the processes realization in repetitive linear projects. In case of realization of non-linear construction objects or construction units, it is usually necessary to choose between the reduction of the project implementation time and maintaining the continuity of crews work on the units. It was found that there is a lack in the literature of developed method enabling harmonization of crews’ work, while minimizing the downtime at work and the duration of the entire project taking into account additional constraints, e.g. the need to not exceed the deadlines for the realization of the project stages.The article presents the concept of a multi-criteria optimization method of harmonizing the execution of non-linear processes of a multi-unit construction project in deterministic conditions. It will enable the reduction of realization time and downtimes in work, taking into account the preferences of the decision maker regarding the relevance of the optimization criteria. A mathematical model for optimizing the selection of crews and order of completion of units in multi-unit construction projects was also developed. In order to present the possibility of usage of the developed concept, an example of the optimal selection of crews and their work schedule was solved and presented. The proposed method may allow for better use of the existing production potential of construction enterprises and ensure synchronization of the crews employed during the work, especially in the case of difficulties in acquiring qualified staff in construction industry.

Sustainable procurement is an emerging theme in the construction industry across the globe. However, organizations in the construction industry often encounter impediments in improving environmental performance in construction projects, especially in procurement. Besides its other facets, procurement of construction equipment is inherited to be capital-intensive and vital for managing environmental concerns associated with built environment projects. In this regard, selection criteria in such procurement processes are generally supportive of considering cost and engineering specifications as key parameters. However, sustainability apprehensions in today’s Malaysian construction industry have mounted pressure on industry professionals to rethink their equipment acquisition strategies. The notion of green or sustainable procurement is still infancy for the Malaysian construction industry and facing challenges for embedding it in the current procurement practices. This research aims to address these apprehensions by considering six main criteria, namely, life cycle cost (LCC), performance (P), system capability (SC), operational convenience (OC), environmental impact (EI), and social benefits (SBs), and their 38 subcriteria towards procurement of sustainable construction equipment. A multicriteria-based equipment selection framework on the triple bottom line of sustainability in the context of the Malaysian construction industry has been developed and tested. The application of analytical hierarchy process (AHP) established the sustainable procurement index with a consistent sensitivity analysis results. As such, the proposed procurement index shall help decision-makers in the process of the acquisition of sustainable construction equipment in Malaysia.
