Investigation of the Adoption of Building Commissioning Practices in the Installation of Building Services Items

Abstract

Of recent, the need to increase the performance of services installations in buildings has been a major point of interest amongst construction professionals through the consideration of commissioning practices required to be adopted during execution of building projects. The aim of the study is to investigate awareness of building professionals on the adoption of building commissioning practices in the installation and use of building services equipment. The study therefore examines the characteristics of building commissioning practices, examines the level of awareness and adoption of building commissioning practices amongst construction professionals in Lagos State, Nigeria, as well as investigates the factors influencing their adoption. A survey method of research was employed with questionnaire administered on construction professionals available on the list of firms of the Federation of Construction Industry (FOCI) registered with the Lagos State Government. The data collected were analysed with the use of statistical tools, such as frequency distribution, mean item score, analysis of variance and factor analysis. The study shows that amongst the characteristics of building commissioning practices, lighting services have the highest level of engagement with a mean score of 4.45, heating, ventilation and air-conditioning 4.15 while vertical transporting services have a mean score of 3.82. A significant proportion of the respondents are aware of building commissioning practices through different professional training courses and practices. The study also shows that there is relationship between the level of awareness and adoption of building commissioning practices at 95 % confidence level. The indicators in group one are found through the factor analysis to be contributing mostly to the adoption of building commissioning practices by the respondents. The study concludes that with the existing level of its awareness in the study area, efforts should be made by stakeholders to entrench building commissioning practices provisions in the country’s institutional framework/regulatory code, which covers the installation and use of service items in building stock so as to further deepen their adoption in order to enhance performance and comfort of building projects.
