ASSESSMENT OF AWARENESS ANDADOPTION OF LEAN PRACTICES IN THENIGERIAN Building Industry
2018Co-Authors: Daniel Olatunde Babalola, Eziyi O. Ibem, I. C. EzemaAbstract:The construction Industry globally is faced with challenges of time overrun, cost overrun, and material wastage. In order to address these challenges, the lean production approach has been adopted in the Building Industry, which is a subset of the construction Industry. Although several studies have examined various aspects of lean practices in the different countries, studies on the adoption of lean principles and practices in Nigeria are grossly underrepresented in the research literature. This study investigated the levels of awareness and adoption of 32 lean practices by firms in the Nigerian Building Industry. A questionnaire survey was conducted in five cities of Abuja, Enugu, Kaduna, Lagos, and Port-Harcourt in five geo-political zones of Nigeria. Totally, 446 participants drawn from architectural, Building consulting and contracting and quantity-surveying firms in the five aforementioned cities provided the data for this research. The data were analyzed using descriptive statistics, and the result shows that whereas around 67% of the respondents claimed that they are aware of lean practices in construction, about 47% of the firms have adopted one form of lean practices or the other. It was also observed that the three most adopted lean practices among the 32 investigated were Visual Design Construction (VDC), Total Quality Management (TQM) and Team Work/Partnering, respectively. This study implies that although there is a growing knowledge about lean practices among firms in the Nigerian Building Industry, the level of adoption of individual leans practices by the firms is generally low. Therefore, for the Building Industry to maximise the benefits of the lean production approach, appropriate steps need to be taken to ensure a critical mass uptake of lean practices by firms in this vital sector of the Nigerian economy.

E-PROCUREMENT USE IN THE NIGERIAN Building Industry
International Journal of Electronic Commerce Studies, 2017Co-Authors: B. E. Aduwo, Eziyi O. Ibem, Emmanuel A. Ayo-vaughan, Obioha Uwakonye, J. D OwolabiAbstract:Since the mid-1990s, the use of electronic (e-) procurement aspect of electronic commerce in the different industrial sectors has been on the increase across the world. However, the extent of its adoption in the Nigerian Building Industry is not clearly understood. This study investigated e-Procurement use in the Nigeria Building Industry with a view to improving understanding of the extent of its adoption in this country. The research involved a questionnaire survey of 213 respondents drawn from consulting and contracting firms, client organizations in the private sector and government institutions conducted in Nigeria in 2015. The data were analyzed using descriptive statistics, Chi-square test and multiple regression analysis. The result shows that the main users of e-Procurement were quantity surveyors and construction/project managers in consulting firms; and that there was a significant relationship between professional roles and e-Procurement use in the Nigerian Building Industry. The most frequently used e-Procurement technologies for announcing/receiving invitation to tenders; exchanging project briefs and specifications; submitting/receiving tenders/bids and sourcing for materials and equipment were e-mails and websites. Age of organizations, top management perception of the benefits of e-Procurement and sector of procurement experience had the most significant influence on e-Procurement adoption in the study area. The study concludes that the private sector was taking the lead in e-Procurement use and that only established organizations whose top management understands the benefits of e-Procurement would most likely adopt it in the Nigerian Building Industry.

Factors influencing e-Procurement adoption in the Nigerian Building Industry
Australasian Journal of Construction Economics and Building, 2016Co-Authors: Eziyi O. Ibem, Emmanuel A. Ayo-vaughan, Egidario B. Aduwo, Patience Tunji-olayeni, Uwakonye O. UwakonyeAbstract:Against the backdrop of increasing adoption of e-Procurement in supply chain management, there is a need for adequate knowledge of the factors that influence the decision by organizations in the Building Industry to use e-Procurement. This study aims to fill the knowledge gap through investigating the factors influencing e-Procurement adoption based on the data sourced in a questionnaire survey involving 213 organizations in the Building Industry. The survey was conducted between June and November 2015 in Nigeria. Descriptive statistics, factor and categorical regression analyses were used to analyze the data. The results show that the three most important factors influencing the adoption of e-Procurement amongst the participants, in order of importance, were: the benefits of e-Procurement in enhancing efficiency in project delivery; eliminating geographic barriers and effective communication among project team members. The 29 factors were investigated in seven different dimensions - the benefits of e-Procurement use; level of awareness on e-Procurement in construction; and the availability and cost of e-Procurement applications emerged as the three most significant predictors of e-Procurement adoption in the survey. The study concludes by identifying strategies that should be engaged in increasing the uptake and maximizing the benefits of e-Procurement in the Nigerian Building Industry.

a review of life cycle assessment method for Building Industry
Renewable & Sustainable Energy Reviews, 2015Co-Authors: Ahmad Faiz Abd Rashid, Sumiani YusoffAbstract:A recent study suggested that Buildings globally consume up to 40% of energy and responsible for half of world greenhouse gas emission. Introducing life cycle assessment (LCA) to the Building Industry is important because it can measure every environmental impact involved in every process from cradle to grave systematically. Within the last decade, research on LCA has increased covering from construction process to manufacturing of Building materials. The methods to assess Buildings are diverse as Buildings have different functions, materials, sizes and locations. The aim of this article is to review the LCA methods and to distinguish phases and materials that affect significantly to environment. The findings show the methods are based on ISO 14040 series with variance to suit different scopes, aims and limitations. The operational phase is identified to consume the highest energy and concrete responsible for the highest embodied energy. The findings also suggested that Building material with lower embodied energy does not necessarily have lower life cycle energy. Therefore, implementation of LCA can determine and mitigate the environmental impacts in the development stage thus promoting sustainability in Building Industry.

subcontracting and occupational health and safety in the residential Building Industry
Industrial Relations Journal, 1997Co-Authors: Claire Mayhew, Michael QuinlanAbstract:This article examines the relationship between subcontracting and occupational health and safety in the Australian and UK residential Building Industry. It is argued that poorer OHS is an important consequence of subcontracting. This finding has implications for theories of injury causation and analysing the impact of outsourcing on industrial relations.
