Description
The Construction Industry of which the building industry is a subsidiary has been identified
as an industry that can help in the achievement of environmental sustainability. Literature has established
practices such as Virtual Design and Construction (VDC), Prefabrication and Modularization and Just-in-
Time (JIT) and others as environmental sustainable LCPs. Therefore, this paper investigated the adoption
of these practices and areas LCPs adoption can help contribute to environmental sustainability in the
Nigerian Building Industry. In order to achieve the aim of the study, a questionnaire survey was
conducted in Abuja, Lagos, Port-Harcourt, Enugu and Kaduna covering five out of the six geo-political
zones of Nigeria. The sample frame for the study consisted of architectural, building consulting and
contracting and quantity survey firms in the selected cities. Totally, 446 valid responses were collected
and analyzed descriptively using the Statistical Package for Social Sciences (SPSS). The results from the
study revealed that firms in the Nigerian building industry have adopted all the 32 investigated LCPs.
Specifically, it was found that VDC was the most adopted of all the 32 LCPs investigated in the Nigerian
building industry. In addition, the result reveals that respondents are of the opinion that adoption of LCPs
in building can help in the achievement of a sustainable environment through massive reduction of
construction wastes that are injurious to the ecosystem.
