It is widely recognized that construction activity plays a vital role in the process of economic
growth and development through its products (viz., infrastructure, buildings, etc.) and the
employment opportunities created in the construction production process (Jha, 2002). Due
to the industry-relative large investment requirement, construction is viewed as a convenient
tool for regulating the economy in most countries (Ojo and Dada, 2005). The state of the
construction industry is also believed to be a good indicator of a nation’s economy (Opoko
and Ali, 2005). Meanwhile, it has been established in the literature that construction is a labor-intensive industry, requiring more human effort (Owor, 1989; Ubenyi, 1999; English,
2002; Loosemore et al., 2003; and Muya et al., 2006). In Nigeria, for example, the industry
was acclaimed to be the highest employer of the nation’s workforce (Fagbenle
et al., 2004). The labor-intensive nature of construction activities in Nigeria was attributed
to the predominance of large number of small-scale construction firms that rely solely on
skilled and unskilled labor for their operations (Owor, 1989; and Ubenyi, 1999). Thus, the
quality and availability of skilled workforce is considered an important factor in the
effectiveness of the construction sector. However, various reports and headlines have indicated
the existence of shortages and poor quality of craftsmen in the Nigerian construction industry
(Obiegbu, 2002; and Njoku, 2007). The reasons attributed for such shortages include aging
of skilled craft workers in the industry, decline in the number of new entrants into skilled
trades, poor funding and ineffective state of vocational education and training system in the
country, others include poor image associated with construction labor as work done by less
intelligent people, lack of commitment by government and the construction industry toward
training and development and the introduction of new technologies and materials requiring
higher skills among others (Kolawole and Frank, 1999; Obiegbu, 2002; Bokinni, 2005;
Nwagu, 2006; and Awe, 2007). Meanwhile, the effect of skilled craft availability has been
well reported in the literature (Olomolaiye et al., 1987; Kaming et al., 1997 and 1998;
and Kazaz et al., 2008). With the ever increasing pressure on construction contractors to
deliver projects of desired quality on scheduled time, the importance of more skilled
craftsmen in the industry cannot be under-rated as the skilled craftsmen have the potential
of eliminating inefficiencies arising from poorly skilled craft availability. Hence, poor
workmanship normally result in rework and decline in productivity among other factors.
