Abstract
The construction industry plays a central and significant role in the economy of any nation. One of
the major reasons for ineffective project delivery in the Nigerian construction industry is the improper
assessment of risk factors. Installation and dismantling of tower crane had been previously looked at
as a general safety issue along with other factors affecting safety during tower crane usage until, recent
research showed that about 69% of accidents related to tower cranes in Korea from 2001-2011, occur
during installation and dismantling process. In view of this, this paper aimed at assessing impact of
installation and dismantling of tower cranes on safely by determining the degree of impact with a view to
establishing the most significant ones. This is why a well-structured questionnaire is designed to collect
data with respect to the degree of impact using a 5 point Likert scale. Responses from the administered
questionnaire and interactions was collated, interpreted and analysed by using descriptive statistics
(mean) and results presented in tables. Results showed that fracture of a wire rope during dismantling
had the highest degree of impact with a mean value of 4.63, workers (erectors, dismantlers) arc leaving
the work often due to hard working condition had the lowest degree of impact with a mean value of 2.34.
The research concluded that fracture of a wire rope during dismantling is a high risk factor affecting
construction site safety during installation and dismantling of tower cranes. Adoption of a preventive
maintenance strategy or routine check on the tower crane parts and components could help reduce the
possibility of accidents occurrence on site and therefore improve safety.
