Abstract Construction projects are characterized by low productivity due to many wasteful activities in construction processes. Wasteful or non-value-adding activities result in quality and profit loss in many construction projects. Consequently, construction needs more effective strategies for process innovation at all stages of the construction project life cycle. Analysis of the current state has shown the possibilities of improving construction processes through the implementation of technologies, methods and procedures of lean construction. Such improvements can help increase the efficiency and productivity of construction projects. Therefore, it is necessary to promote more effective construction waste management by identifying the causes of non-value-adding activities during the construction phase, and apply the gained data to eliminate wastes during the planning phase. The paper presents the most appropriate technologies and methods for collecting data on non-value-adding activities.

Purpose This paper aims to enlighten the importance of the risk management process which is considered as a major procedure to effectively handle the potential inherent risks in the construction industry. However, most traditional risk analysis techniques are based on theories that deal with each risk factor as an independent, which does not take into consideration the causal relationships between risk factors. Design/methodology/approach This study aspires to identify the overall risk of the administrative construction projects in Egypt and to recognize the most influencing risk factors through the project life cycle by using Bayesian belief networks (BBN). Through a review of the literature, 27 risk factors were identified and categorized as the most common risk factors in the construction industry. A structured questionnaire was performed to estimate the probability and severity of these risks. Through site visits and interviews with experts in the construction field, 200 valid questionnaires were collected. A risk analysis model was developed using BBNs, then the applicability of this model was verified using a case study in Egypt. Findings However, the outcome showed that critical risks that manipulate administrative construction projects in Egypt were corruption and bribery, contractor financial difficulties, force majeure, damage to the structure and defective material installation. Practical implications The proposed study presents the possibilities available to the project parties to obtain a better forecast of the project objectives, including the project duration, total project cost and the target quality by examining the causal relationships between project risks and project objectives. Originality/value This study aspires to identify the overall risk of the administrative construction projects in Egypt and to recognize the most influencing risk factors through the project life cycle by using BBNs.

The issue regarding sustainability has emerged significantly in the construction industry. The appealing concept and the future benefits of sustainability have enamoured people to implement this notion progressively. This situation resulted in a trend in the architectural and engineering world. The Gold Coast city, which is located in the southeast of the Australian state of Queensland, is one of the world leading examples in which a government has put a green legacy as the concern in its development. One of the implementations of its sustainability concept is described in its waste management. This study explores the waste management in Gold Coast city in three stages of the project life cycle (PLC): design, construction, and operation. The cost-benefit analysis in qualitative and quantitative approach will be employed to provide the explanation of cost reduction that is achieved by the implementation of specific actions. However, the result of this study shows that the implementation of waste management does not only benefit in cost, but also many other aspects such as energy, built-environment, diversity, carbon critical design, and community lifestyle. This exploration can be the reference to the best practice of sustainability concept implementation in waste management.

Purpose Building information modeling (BIM) has been proven to enable outstanding results in construction processes by enhancing knowledge sharing with regard to a building or facility throughout its life cycle from the conceptual design to facility management. The purpose of this paper is to investigate the extent to which the use of BIM has impacted the legal and contractual implications of the existing construction contracts for aligning the three sets of relevant development domains: BIM functionality, contract procurement methods, and BIM legal and contractual issues to enhance the efficient use of valuable resources. Design/methodology/approach This exploratory study was undertaken by analyzing the literature using a novel approach involving a matrix that juxtaposes BIM functionalities for each project life cycle with contract procurement methods. As part of the study, 28 interactions of BIM legal and contractual issues have been identified, as representing positive and negative interactions. Findings The interaction matrix framework that juxtaposes BIM functionalities and procurement methods highlights the theoretical and practical relationships identified between the methods. It also simultaneously recognizes the constructive and destructive interactions between these development domains by means of critically identifying the possible interactions of the legal and contractual aspects of both the BIM project procurement and the practical aspects of BIM project delivery. Originality/value The present study contributes to the existing literature by extensively identifying the probable interactions of contractual issues within BIM functionality with contract procurement methods throughout the life cycle of a building construction project.

The construction industry is well-known for generating the largest amount of waste amongst other industries, which significantly pollutes the environment. This study, therefore, examines the causes and sources of waste in construction projects, considering activities, inputs, and outputs of each phase of the construction projects’ lifecycle (i.e., concept, definition, deployment, and transition). Thirty semi-structured interviews were conducted with professionals in construction projects in Jordan, including architects, contractors, and project administrators. The findings reveal that waste resulting from construction projects passes across several organized operations from generation to final disposal. Furthermore, waste is generated in small amounts at the early stages of the project construction but grows as the project progresses towards the end. This paper’s key contribution is to supplement the literature on waste management solutions by providing a holistic approach to tackling waste at its root by including waste management strategies across the project lifecycle phases, not only during the construction phase. This is done with a management readiness view to develop a suitable strategy for construction waste minimization and improve the management of construction projects. This study’s practical implication is providing a holistic waste management framework for practitioners to adopt in the early stages of the project.

Waste generation is a major issue faced by construction projects. Construction waste has adverse effects the time, cost, productivity and economy of the industry. There are different causes of waste generation in different countries of the world. An extensive literature was carried out to identify the common factors of construction waste generation which resulted in identifying 59 common attributes. Through structured interview data was collected to classify the attributes on different stages of construction project lifecycle. A total of 15 experienced practitioners were interviewed classify the attributes into different stages of project life i.e. planning, design, construction and finishing. Frequency analysis of the perception of the practitioners showed that there are 25 attributes in planning stage, 9 in design stage, 53 in construction stage and 5 in finishing stage. From the findings it can be seen that construction stage is the critical stage in which 53 attributes are occurring. This study shows that the practitioners need to be very careful during construction phase for controlling construction waste generation.
