Waste in the construction industry has been the theme of several research projects around the world in recent years. Researchers implement different methods to reduce the amount of waste in the construction industry. In the construction industry, contractors only consider physical waste which leads the project to cost overruns. i.e. material waste. Construction industry is also affected by time overrun. Impact of time overrun on the construction projects is considerably high and requires special attention in addition to physical waste. In the present study, construction waste is categorized in mainly of two types: value added waste and non-value added waste. This categorization includes both-material waste as well as time waste, which are main causes of occurrence of waste. A case study was also carried out at a residential building project in Ahmedabad, Gujarat to get the idea about the percentage of waste occurs in a construction project.

Construction practitioners recognise that rework is undesirable due to the detrimental effects. While rework literature has examined rework causation factors in construction projects, the problem continues to plague the industry resulting in poor delivery performance. To better understand this phenomenon and given the scarcity of Malaysian-based rework study, a questionnaire survey involving 130 Malaysian construction practitioners (consultants, contractors and clients) were undertaken to obtain feedback about nature, implications, causes and solutions for rework. Data were analysed using descriptive statistical techniques to prioritise the variables studied. From the analyses, rework is a causal factor for delays and cost overruns, higher wastage and productivity inhibitor. The findings revealed the leading causes of rework are poor quality management, improper planning, lack of communication, design changes and poor subcontractor management. Some practical rework minimisation approaches are also suggested to better manage and prevent rework towards enhanced project performance.

AbstractRequest for information (RFI) is a formal process used in the Architecture, Engineering and Construction industry to address design flaws that affect communication between designers and contractors. A large number of RFIs are a sign of a lack of precision or coordination in the design documents. However, RFIs produce rich, precise, and structured information. Analyzing their content can help to identify recurring problems between designers and construction teams and better tailor future projects to the working context of the contractors. This article presents a method for identifying recurring issues during the design phase of steel construction projects through the analysis of the contents of RFIs. It is original in using a qualitative content analysis tool that can analyze large quantities of RFIs rapidly. Identifying the recurrent problems of contractors will allow the establishment of rules to be taken into consideration during the design phase of future steel construction projects. A case study of 26 steel construction projects demonstrates the feasibility of this method. This case study shows that, given the same designers and construction teams, recurring problems shown in RFIs do not differ according to the scale of the projects. In this case, the main issue between designers and contractors is the lack and inadequate presentation of information related to the connection of steel components. Identifying these problems can pave the way for initiatives to improve the design phase and can be an essential step in making contractors’ knowledge available to designers early in the projects.

This research investigates how contingency is currently calculated in project budgets within the building industry. This is an important aspect to consider as a large proportion of construction projects are significantly over-budget. The study presents three non-simulation methods and one simulation method for calculating cost contingency following the results of a forthcoming journal paper. These methods are applied against a case study project in attempt to highlight the most reliable method, and to create a methodology that will be useful to the industry. This paper identifies that the traditional fixed percentage approach is not sufficient and suggests that this could be one of the main reasons why construction projects are over budget. While it is unclear which method is the most reliable, this study provides a focus for future research into reliability and utilisation of contingency methods in the building industry. The research demonstrates that current practice needs to change to reduce the large number of construction projects that run over budget.

Purpose Although there is a boom in the construction industry in the Kingdom of Saudi Arabia (KSA), it is yet to fully adopt building information modeling (BIM), which has received a lot of attention in the US, UK and Australian construction industries. Thus, the purpose of this paper is to provide the current state of the art in BIM implementation in Saudi Arabia, as well as perceived benefits and barriers through a case study. Design/methodology/approach A broad overview of BIM, the construction industry in KSA and the research and implementation of BIM in KSA was presented in this study. The research further established the perceived benefits and barriers of BIM implementation through a case study of a local AEC firm. A questionnaire survey was used to obtain lessons learned from the BIM team of the pilot project and was further analyzed using the RII approach. Findings The study’s findings include the lack of policy initiatives in KSA to enforce BIM in the construction industry, as well as the lack of sufficient research in the domain of BIM in KSA. Furthermore, the case study also revealed that the most important benefit of BIM adoption is “detection of inter-disciplinary conflicts in the drawings to reduce error, maintain design intent, control quality and speed up communication,” whereas the most important barrier is “the need for re-engineering many construction projects for successful transition towards BIM.” Originality/value The study provides a background for enhanced research towards the implementation of BIM in Saudi Arabia and also demonstrates the potential benefits and barriers in BIM implementation.

Temporary safety facilities (TSFs) are an essential support system providing necessary protection to workers during construction activities, which are targeted towards preventing the occurrence of incidents and accidents at the construction site; however, the schedule and location of installation and demolition of TSFs continue to rely on labor experience, and are often omitted from formal drawings or documents. This results in thousands of accidents in the construction industry, especially in construction small and medium-sized enterprises (SMEs) because of their several limiting factors; therefore, this study proposes automatic workspace planning for TSFs based on construction activities, which is a systematized approach for construction SMEs to practice occupational health and safety (OHS). By using building information modeling (BIM) and add-in algorithm, safety facilities can be simulated and visualized to integrate into the designated workspace. The developed system was implemented utilizing 4D-BIM for TSFs installation and validated with a case study on a residential building project. The result revealed that the visualized TSF produces a better understanding of safety measures with regard to project schedule. Additionally, TSFs workspace planning provides an affordable approach that motivates safety practices among the SMEs; consequently, the effectiveness of construction safety measures and their management is enhanced appreciably.

This paper presents findings of an investigation into benefits of using Building Information Modelling (BIM) in construction projects. The research methodology includes a review of BIM development and achievement in construction industry, questionnaire survey, interview, and content analysis of secondary data. Data was collected and analyzed to identify the various benefits reflected from BIM implementation in addressing common problems experienced by the construction industry. The review and survey results indicate that a high frequency of occurrence of time and cost overruns occur in construction projects. Contributing factors were mainly rework, poor planning, documents delivery and approval, constructability issues, resources and weather condition. While some of the factors were unpreventable, BIM could be used as a tool to eliminate problems causing time and cost overruns. Various project benefits have been reflected through the content analysis of project case studies. It was found that time was the most positively influenced by the use of BIM followed by coordination, procurement, communication, cost and change of scope of the project, and lastly, risk.
