Therefore, the aim of this study was to determine the impact of offsite production in the delivery of mechanical and electrical installations for construction projects. In this study, a mixed method was adopted, using quantitative data obtained through a questionnaire survey and qualitative data through case study interviews. In total, primary data was collected from 36 questionnaire responses, and 3 case studies that involved 12 in-depth interviews. This study shows that offsite production has a positive impact on construction project performance indicators for M&E installations regarding factors such as time, quality, health and safety, sustainability, logistics, and collaboration. However, the study showed no general conclusion as to the cost saving impact of offsite construction on the outcomes of projects. Nevertheless, the study established that the offsite approach offers the client more confidence relating to cost certainty. Recommendations from this study are that offsite production should be selected based on its impact on project performance indicators rather than cost alone. The study argued that the offsite production method should be explored as much as possible when maximal benefits are sought; however, it should not be utilised simply for the sake of it but on a case-by-case basis.

This study describes the Trends, in-hospital outcomes, and independent predictors of Acute Kidney Injury (AKI) in patients admitted for Myocardial infarction with Percutaneous Coronary Intervention (PCI).MethodsThis retrospective study used patient records from the 2016-2020 National In-patient Database (NIS). We identified patients who were admitted for the management of an MI who had a PCI procedure and an AKI and evaluated their associated socio-demographic and comorbid factors using International Classification of Diseases-10 (ICD-10) codes. The chi-square test was used to compare baseline characteristics between our populations with and without AKI and outcomes and multivariate logistic regression to identify independent predictors of AKI.ResultsThere were 1,551,630 patients admitted for an MI and PCI...

Offsite has been touted as cheaper, faster, higher in quality and more environmentally friendly than onsite construction. The purpose of this paper is to review the current research into offsite construction and determine the barriers to adoption and benefits facing offsite construction. A systematic literature review was undertaken to gather relevant knowledge surrounding the subject matter using a database search of Scopus. It was found that knowledge was the largest barrier to adoption and that transcended multiple stakeholders, from the selection of the appropriate delivery methodology, how to design for optimized fabrication and finally how to interface with the onsite requirements. The benefits are a higher build quality, shorter project duration as both site work and fabrication occur at the same time, improved safety, and less material wastage. The Barriers come from design freezes earlier in the process and inflexible design for customization later in the build.

There is a real opportunity to conjoin OSC and CE to provide new insight and opportunities to deliver more evidence-based sustainable systems. This study analyses extant literature in CE and OSC (between 2000 and 2021) through a bibliometric review to tease out critical measures for their integration and transformation.Design/methodology/approachThis study adopts a science mapping quantitative literature review approach employing bibliometric and visualisation techniques to systematically investigate data. The Web of Science (WoS) database was used to collect data, and the VOSviewer software to analyse the data collected to determine strengths, weights, clusters and research trends in OSC and CE.FindingsImportant findings emerging from the study include extensive focus on sustai...

Such disparity is important because it can lead to different conclusions and thus disagreement on the assessment of project success.Design/methodology/approachThe philosophical stance was interpretivism, thus the qualitative methodology was adopted. Employing purposive sampling, 30 interviews with clients and another 30 interviews with contractors were conducted in Saudi Arabia. The data obtained were evaluated by thematic analysis.FindingsThe results indicate differences in the consensus ad idem (meeting of the minds) between clients and contractors in terms of both their perceptions and prioritisation of the attributes that underpin client satisfaction. For example, some contractors thought that using advanced technologies was very important for client satisfaction, whereas some clients preferred the contractors to be honest with them.Research limitations...

Based on a comprehensive search using Scopus, Web of Science and the International Group for Lean Construction databases, 66 relevant journal articles were identified and analysed.FindingsThis study found that the most significant impacts of the combined application of LOS in housing delivery are the capacity to visualise the production processes as a whole in real time, exposure and removal of non-value-adding activities from the production and faster delivery. However, the combined application of LOS is low compared to a single application of each technique in housing delivery.Practical implicationsThe results provide relevant stakeholders and actors in the housing sector (private and public housing developers, off-site housing manuf...

The greenhouse emissions have been associated with the rise in global temperature. The increase in global temperature is principally responsible for the rise in natural disasters which is being experienced in most coastal cities around the world. Information gleaned from literature suggests that the adoption of sustainable construction practices would results in significant reduction in greenhouse emission from the construction sector. While the call for sustainability practice in the built environment sector has received much attention from clients, contractors, small and medium scale companies, researchers, social enterprises, Government and its regulatory bodies in countries such as the UK, USA, New Zealand, Australia among others. There is limited study that has examined sustainable construction practice in developing country such as Nigeria. Additionally, the barriers to its adoption in Nigeria still remain unclear. The key question therefore is; what are most significant barriers to sustainable construction practice in Nigeria? The aim of the current research is to assess the barriers to the adoption of sustainable construction practices in Nigeria. A total of 150 questionnaires were disseminated to major construction industry stakeholders based in Abuja, Nigeria. The study found that lack of expertise, lack of strategy to promote sustainable construction and lack of demand are the most significant barriers to the adoption of sustainable construction practice in Nigeria. Addressing these barriers would improve the use of sustainable construction practices in Nigeria and other similar developing countries

However, the coronavirus disease 2019 pandemic has led to the cancellation of many international conferences; thus, virtual conferences have received a great deal of attention. Their expanding role has created an urgent need to explore the best approaches for successful execution. However, there is limited empirical evidence on the organization of these conferences. This study aims to offer a comprehensive analysis of the key success factors through a case study of the International Group for Lean Construction’s first virtual conference. The results revealed the influence of multiple factors. In addition, a successful model for an international virtual academic conference is proposed. The model contributes to the knowledge of sustainable development in engineering management and architecture, engineering, and construction practice.

The construction project team is established temporarily to better achieve project targets, and the establishment and acquisition of its social capital became difficult in the process of construction because of the temporary characteristics. In the early stage of project construction, the construction project team often has a lot of implicit social capital which cannot be effectively utilized. Based on the Johari Window model in the cognitive psychology field, we propose a new model of construction project team’s social capital and divide the dimensions of a construction team’s social capital from a dynamic perspective, namely explicit social capital, private social capital, unknown social capital, and blind social capital. This paper explains the connotation of each type of social capital of the construction teams and discusses the strategies to transform the implicit social capital to explicit social capital, to provide the theoretical foundation and practical guidance for the establishment and cultivation of social capital in actual construction projects

Through apprenticeships, different sectors that are underpopulated can fill up their skills gaps. Apprenticeships are particularly useful to the construction sector which has a high ageing workforce and associated lower labour productivity. However, the completion rates of apprenticeship training programmes in the construction sector remain low in several countries across the globe. Thus, the purpose of this paper is to review the published research on apprenticeship training that is specifically focused on the construction sector, to determine the current status quo and suggest a direction for future research.Design/methodology/approachA systematic review approach was adopted. Based on a comprehensive search using SCOPUS databases, 33 relevant journal articles were identified and analysed.FindingsIt was found that monitoring and control is the most mentioned factor responsible...

The absence or fluctuation of data for estimating the cost of transporting cement from each source to each distribution center is a big stumbling block whenever modeling attempts are being made via transportation algorithms. This work has succeeded in removing these challenges by providing a Transportation Optimization Model for cement distribution using transportation Distance Matrix instead of transportation Cost Matrix. This research seeks to improve supply in the Nigerian cement industry. Three selected factories (Gboko, Port-Harcourt and Calabar) and four major distribution centers (Abakaliki, Onueke, Ohaozara and Afikpo) in Ebonyi state were considered for this work. The result of the findings using the Vogel Approximation Method, minimized the total transportation distance and by implication the total transportation costs.
