Safety is very important aspects of construction projects which are the most hazardous endeavors have many work-related injuries and accidents. Accordingly, safety factors must be considered in project lifecycle from beginning of a project to its end. To improve project safety, the definition of safety factors and determination of their importance are necessary. In some of the previous researches several safety factors are introduced. In this paper, safety factors in construction project are reviewed and categorized as well as an exhaustive classified catalogue of critical safety factors in construction project which don't have unnecessary details is developed. The identification of the critical safety factors which are categorized in four main groups consists of safety approach, safety engineering, safety management and safety on construction site will enable appropriate allocation of limited resources.

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.

Through analyzing the causes of safety accidents in hydraulic construction projects, this article argues that the main direct causes of safety accidents are working against regulation, commanding against regulation and ineffective technical countermeasures. However, the deep reasons are mainly human side factors: people are usually hard to keep absolute consciousness within eight working hours, and generally have such mental inclinations as subjective assuming, trying fortune, energy-saving, rebellion, etc. So, for hydraulic construction project safety management, taking account of human side factors and implementing corresponding countermeasures are fundamental.

Construction projects experience various problems and complex factors such as cost, duration, quality and safety. Construction sector is diverse as it contains sub-contractors, contractors, consultants, architects, owners, and others. The aim of this paper is to identify and analyze resource management issues in construction project. Other than that is to ascertain the significance of the resource management as one of the key element in construction project success. A literature review and a questionnaire survey were done for data collection and analyzed using Relative Importance Index and Cronbach’s alpha. The questionnaires were distributed to the team members of KLIA 2 – New Low Cost Terminal Project: Client, Architects, Main Contractor, and Sub-Contractor. The findings revealed that dependent on foreign workers to respond to the high demand of skilled workers, weather condition affecting machineries/equipment-work-related performance and weaknesses in quality assurance for the supply of construction materials should be given serious attention in order to ensure the productivity and financial performance of the projects. Keywords: Construction Project Management, Resource Management, Manpower, Machineries, Materials

Appropriate planning and effective monitoring of the execution of construction projects is important with regard to their successful sustainment of implementation. Time and cost are key elements that determine the success or failure of construction projects. The obtaining of a rational S-curve course before the start of a construction project that reflects reality is important for all the participants involved in implementing an investment task. The article proposes an original methodology for planning the course of the cumulative cost curve in construction projects. It uses a method of shaping the S-curve, which is well-known in both literature and practical approaches. On the basis of the authors’ own research carried out in a homogeneous research group of hotel facilities, the areas of the curve for the correct planning of costs in construction projects were designated, which determine the boundaries of the predicted costs accumulated over time. The data for the development of the authors’ research methodology is the result of the authors’ own experience and professional work. The authors carried out Bank Investment Supervision in the years 2006–2019 on behalf of the banks that grant investment loans for non-public contracts. Knowing the total cost and duration of the planned construction project, which were determined on the basis of project documentation, cost estimates, and also their own database regarding planned and completed deadlines and budgets of similar investments, 6th degree polynomials of the real costs of the construction works were determined. This approach enabled the correct planning of costs over time and the determination of planned monthly amounts of construction works to be executed.

Purpose – The focus of this work is on the client-designer interface where decisions have significant impact over the lifecycle of the project. Therefore, the briefing stage is examined in the context of clients’ needs which is divided into project-based strategy and broader clients’ strategy. The purpose of this paper is to address the pitfalls in the briefing process which has been attributed to the shortcomings in the client-designer communication interfaces. This will be achieved by developing an automated brief generation framework. The research examines the efficiency of standard approaches to modelling and design, and the benefits that these methodologies have offered to the computer industry. The work reviews the similarities between the two industries and argues in support of the potential benefits in adopting a standard methodology in the construction industry. The structure upon which the framework is developed is based on system analysis and design methodology (SSADM) which has proven to be an effective platform used within the software development industry. Design/methodology/approach – SSADM is an established methodology within the software development industry. The paper will demonstrate that due to fundamental similarities between the construction and software development industries, SSADM is likely to offer a viable platform upon which an automated enhanced brief generation model is developed for use in the construction industry. The construction design and construction process will be mapped on SSADM high-level definition before focusing and honing on the design phase. The methodology for the development of the framework will be based on the rationalist approach of generating knowledge through reasoning leading to model-building. Findings – A model that is based on SSADM is proposed for the design development phase of construction projects. In order to shape the project strategy, the model considers the combined role of clients’ requirements with organisation strategy and environmental factors. The paper has shown that it is feasible to increase the automation of the briefing process and enhanced the briefing output. The model here does not diminish the importance of direct communication between the client and the design team. It provides a more structured way of doing so, while taking advantage of vast array of data and technology in order to improve the brief outcome. Research limitations/implications – From practical perspective, the proposed framework is in its formative stage, thus requiring incremental refinement through several case studies. This is particularly true about the AI components of the system which typically rely on extensive data representing the real-case scenarios. Therefore, the work invites further research into the examination of various parts as well as the overall system. Practical implications – There are several ways by which construction projects are procured. There may be fluctuation in their rate of usage, but while there is no indication of any procurement option fading, new ones such as PPP and PFI are periodically introduced. The existence of this diversity is indicative of the fact that the industry tends to respond to problems rather than attempting to instigate a measured solution supported by theoretical underpinning. Subsequently, there have been suggestions of a communication and information discourse between actors and within processes involved in project lifecycle. This project is aimed at addressing the gap in the client-designer communication. The automated approach to brief generation will lead to better briefs while reducing ambiguities as well as the overhead associated with brief generation. Social implications – The quality of project brief has a significant impact on decisions at the design stage. In turn, these decisions will influence all phases of construction project lifecycle. The briefing session and requirement analysis of a construction project can be very difficult for inexperienced clients particularly for complex projects. Therefore, there is potential for the process of client-requirement-analysis to be optimised. The work promises to improve the quality of the briefing process, thus helping clients to realise their intended objectives and minimise resource waste. Originality/value – The work builds on the commonalities of the construction and software development industries and takes advantage of the advancements in the latter. In doing so, project quality is defined quantitatively which is used to develop project strategy in a three-dimensional space. The development of the model was also contingent upon enhancement of artificial neural network structure.

Construction objects arise during the implementation of construction projects. Participants in these projects are interested in taking systematic actions to improve the state of occupational safety and health protection. The effectiveness of these activities requires that they be carried out as part of a comprehensive system of managing the construction project implementation process.The safety management and health protection system is part of the overall project management system, which includes: organizational structure, planning, responsibility, rules of conduct, procedures, processes and resources and requires analysis of safety and health protection issues in its individual areas, phases and stages. This is primarily due to the fact that proper management is the most effective way to ensure an adequate level of safety and health protection (S&HP), desirable both due to the need to comply with legal provisions in force in construction, social expectations, and the possibility of obtaining positive economic effects by individual process participants in the scale of the entire construction project.The article proposes a theoretical model of the built undertaking that can be used to recognize the state of bioses. The model distinguishes parts, activities and areas in accordance with the logical course of the process, which was assigned to individual stages of the project. A research tool - RADAR S&HP - was developed to identify the factors affecting S&HP. To assess the condition of bioses, an analytical and mathematical model of the examined undertaking was formulated to ultimately determine the directions of preventive actions in the field of safety and health protection at individual stages, phases and areas of the construction project implementation process.

The determination of the magnitude of value of productivity is the first step that must be conducted to determine magnitude of increase productivity that can be applied in construction projects. The determination of value of productivity requires the completeness of data obtained from workers data collection. Data collection displayed in form of Crew Balance Chart to get unproductive time and coefficient of workers based on field conditions in the installation of brick and to increase the productivity of workers on construction project of Residential Houses Cempaka Baru. Methods of data collection using observations in the field, as well as the data processed by using simple math. From the results of the research known to time is unproductive time of workers on the job installation of brick wall construction projects Cempaka Baru on front area is 9,711%, and on back area is 48,737% so it can be called that workers in the front area is quite productive while the workers in back area tend to be not productive. The productivity of workers front area amounted to 0,98 m2/h while productivity in ideal conditions can reach 1,33 m2/h, while that for back area the productivity 1,53 m2/h while productivity ideally 2,25 m2/h.ABSTRAKPenentuan besarnya nilai produktivitas merupakan langkah awal yang harus dilakukan untuk mengetahui besarnya peningkatan produktivitas yang dapat diterapkan dalam proyek konstruksi.

Transaction costs occur when a good or service is transferred across a technologically separable interface, and include the costs of drafting, negotiating and enforcing an agreement, and also the costs of governance and bonding to secure commitments. In the complex and high risk environment of a construction project, questionable decisions can be made in the planning and design phase, and disagreements, conflicts, disputes, change orders, and claims can occur in the construction phase. These problems contribute to an increase in transaction costs. Transaction costs at the pre-contract phase of a project are different from the transaction costs at the post-contract phase. However, there is no consensus on a standard definition of transaction costs in construction projects. In this study, a detailed literature review focusing on transaction costs in construction project management is presented. The factors that affect transaction costs are identified and categorized under the headings of the owner’s and contractor’s roles in the transaction, project management efficiency, and the characteristics of the transaction environment.
