Impact of Landuse Morphology on Urban Transportation

People, cities, nations and the world, in general, would remain largely underdeveloped without transportation systems. However, Transportation puts significant pressure on land use and poses a great challenge to urban sustainability in developing countries. This study examines the influence of Land use structure on Intra-urban transportation in the developing city of cities in the West African sub-region – using Enugu city as a case study. The study uses a descriptive research method. A survey was carried out in six districts within the Enugu metropolis based on a stratified, purposive sampling technique. Questionnaires were used as data collection instruments; 400 respondence participated in the study employing Yamane equation. Furthermore, a twelve-hour (7 am to 7 pm) traffic count was conducted to assess traffic volume. The study finding revealed that Transportation within the urban areas is significantly impacted by Land-use structure, city morphology, neighbourhood characteristics in terms of population and residential density of the city. The hypothesis suggests no significant difference between the various land uses across the Enugu metropolis (p = 0.129). It was also discovered that an average of 122,431 Passenger Car Units (PCU) constantly ply the metropolis roads to service a total population of 564,725 daily, indicated a high rate of car dependency. The study surmises that land use generates vehicular traffic, which impacts the socio-economic environment and the effectiveness of the transportation system. The significance of this study is that the findings contribute to the existing knowledge base that would advance stratic policy formation towards acceleration of the uptake of sustainable urban transportation systems in the region. Doi: 10.28991/cej-2021-03091758 Full Text: PD

Apprenticeship for craftspeople in the construction industry: a state-of-the-art review

Purpose: Apprenticeship programmes are designed to provide young trainees with essential broad-based skills. 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/approach: A systematic review approach was adopted. Based on a comprehensive search using SCOPUS databases, 33 relevant journal articles were identified and analysed. Findings: It was found that monitoring and control is the most mentioned factor responsible for improvements in the completion rates of apprenticeship training. In contrast, the length of time required for going through the full training is the most common factor responsible for low completion rates. Three research gaps were identified, among which is the dearth of studies that has focused on apprentices training in developing countries. Research limitations/implications: The gaps identified in the current knowledge on apprenticeship training would serve as a justification for future investigations. However, the scope of the review is limited to papers published in academic journals and citable through SCOPUS. Practical implications: The outcomes of the study provide researchers and other relevant stakeholders with a concise report on the findings of previous studies. It also provides insight into strategies for improving the completion rates of apprenticeship training in the construction sector. Originality/value: A systematic evaluation of the extant literature draws on theoretical evidence and highlights the factors that are more likely to influence the outcomes of apprentice training for craftspeople in the construction sector

Implementation of BIM and lean construction in offsite housing construction: evidence from the UK

This is an accepted manuscript of an article published by IGLC in the Proceedings of the 29th Annual Conference of the International Group for Lean Construction (IGLC29), Alarcon, L.F. and González, V.A. (eds.), available online: https://iglc.net/Papers/Details/1906 The accepted version of the publication may differ from the final published version.The benefits of integrating Lean construction (LC) and Building Information Modelling (BIM) have been discussed in recent research studies. However, the effects of implementing these methodologies as an integrated approach in offsite housing construction (OSHC) processes have not been explored in the UK. This research aims at assessing the current situation of the implementation of BIM and LC in OSHC in the UK. A quantitative research method was adopted in the study and thirty-two questionnaire survey responses were received from professionals and practitioners of Lean, BIM and offsite methodologies in the UK construction industry. The study found that there is increasing use of LC and BIM in the development of OSHC projects in the UK. It further reveals that these two methodologies when appropriately implemented can bring several benefits. This study sheds light on the current status of implementation of BIM and LC in OSHC and the benefits of the implementation of both BIM and LC in OSHC processes in the UK

Exploring the application of internet of things (IoT) for energy efficient buildings in Nigeria. A review

Paper presented at the 13th International Conference on Construction in the 21st Century (CITC-13) Arnhem, The Netherlands, May 8th–11th, 2023.The global adoption of smart building technologies has been facilitated by the present shift toward Internet of Things (IoT). Despite its benefits, its adoption is still relatively low in developing nations like Nigeria. Therefore, this paper aims to investigate the application of IoT for greatest energy efficiency in buildings, with a greater focus on Nigeria. A review of relevant literature was carried out, to identify the application of IoT in buildings, the current state of IoT application in the Nigerian built environment sector, characteristics and current practices of Nigerian residential buildings regarding energy consumption patterns. A total of 60 papers were reviewed using a narrative and content analysis method. This paper highlights; the lack of smart sustainable building construction in Nigerian and explores the application of IoT for monitoring and visualising the performance of buildings in Nigeria with the aim of optimising efficiency in energy usage. The review has identified research gaps and potentials which can be explored further

Interrelations between construction ethics and innovation: A bibliometric analysis using VOSviewer

This is an accepted manuscript of an article published by Emerald in Construction Innovation: Information, Process, Management on 08/03/2022. The accepted version of the publication may differ from the final published version.Purpose Many companies invest in innovations because of the inherent benefits and research on innovation have increased over the year. However, the vast majority of research papers deal with purely technical matters. There seem to be growing concerns over ethical issues in adopting innovations in the construction industry. This extant review of literature aims to analyse the interrelations between the concepts of ethics and innovations in construction research to understand the advances of current scientific production and future lines of research. Design/methodology/approach Thus, this work presents a bibliometric analysis covering articles obtained from the Web of Science Core Collection Database (WoS) published between 1995 and May 2021. A sample size of 5786research papers relevant to the study was evaluated using VOSviewer software. Findings The results of the analysis shed light on the evolution of the connection between the two concepts. The study highlighted Heng Li as the most productive author. The country with the most publications and citations is China. The most productive institution is the Hong Kong Polytechnic University. The results revealed a limited intellectual exchange and lack of cohesion characterising the two concepts (ethics and innovation), resulting in a situation whereby innovation-related researchers tend to follow personal trajectories in isolation from ethics-related researchers in the construction field. Originality/value This is probably the most comprehensive scientometric analysis ever conducted to examine the theoretical relationship between ethics and innovation in construction. This study adds to the so far limited knowledge in the field and provides insights for future research. Overall, this review may spur future research on dyad investigation of ethics and innovative related themes in construction such as ethics and sustainability, ethics and sensor-based technology and ethics and innovative safety approach

The impact of disruptive events on built environment degree apprenticeship delivery - A case study of COVID-19

This is an accepted manuscript of an article due to be published by Emerald in the International Journal of Building Pathology and Adaptation. The accepted manuscript may differ from the final published version.Purpose: This study aims to understand the impact of the covid-19 pandemic disruptive event on delivery of the built environment degree apprentice programme in higher education in the UK and identify the key strategies to minimise the effect. Design/methodology/approach A qualitative approach was used to collect and analyse data from a sample set of built environment degree apprenticeship stakeholders. Semi-structured interviews was conducted with seventeen key stakeholders to collate emerging themes on their perceptions of the impacts of the pandemic and strategies to adopted to minimise it. Findings: The investigation reveals that the core impacts of covid-19 on the apprentices training programme are lack of access to the site, furlough, limited access to off the job training, limited interaction with tutors and peers, too much time on the screen, limited pastoral care and lack of contact with a mentor. The census from the research participants is that despite the development and gain with the various virtual platform used during pandemic physical meetings with their mentor remain pivotal to the built environment apprentices learning and training. Practical implications: The results provide relevant stakeholders and actors supporting degree apprentices training programmes (training providers and employers, among others) with the information needed to improve the delivery of Built Environment degree apprenticeship training programmes during a disruptive event covid-19. The study identifies various strategies to minimise the impact of disruptive events on the apprentices training, including technology, regular meeting with mentors online, and personal and pastoral care. Originality: The study is the first to document the impact of the COVID-19 pandemic on degree apprenticeship programs in the built environment. It provides an in-depth understanding of how these programs have been affected and offers potential solutions to reduce or mitigate potential damage. The research will inform future policy decisions related to degree apprenticeship programs in the built environment
