Factors Influencing Waste Generation in Buildings Project in South-West, Nigeria

Abstract

The study was aimed to assess the factors influencing waste generation in buildings project in southwestern, Nigeria. The study randomly sampled 261 professionals through a questionnaire survey. Tables and figures were used to present the collected data and ranking and percentage were used to analyze the data collected. It was revealed that Design (Frequent design changes and poor design) lack of early contractor involvement, last-minute client requirement, engagement of inexperience designer, undefined project brief, poor design quality are the most important factors that influence l waste generation during buildings project. It was recommended that site operatives and craft men should be equipped with waste minimization knowledge, they should carry along in every management decision regarding waste management plan development as a major player on sites.

Labour–specific Factors Influencing the Volume of Construction Waste Generation in the Construction Industry

“…A survey of homeowners in Istanbul in Turkey by Esin and Cosgun (2007) showed that waste generation downstream of construction projects are caused mainly due to poor workmanship resulting from the use of unskilled labour, insufficient tools and poor workplace conditions. In Australia, Ajzen's 'theory of planned behaviour' was adopted by Teo and Loosemore (2001) to investigate the attitudinal forces that influence behaviour at the operative level. The study found that construction operatives believe that waste is inevitable.…”

Professional Perspicacity of Building Procurement on Waste Management in Construction Industry

“…The previousstudy on building procurement waste management in the construction industry is dated as far backed and not directly address to the aim of this study. However, the level of waste generated by the industry has continuously increased, other studies have also investigated the causes of waste in the construction industry in Southwestern part of Nigeria (Chooi, Takeshi, & Chin, 2018; Ajayi, et al, 2017; Eze, Seghosime, Eyong, & Loya, 2017; Adewuyi & Odesola, 2015; Albert, 2014).This paper will contribute to studieson practices,understanding that will generate activities that are related to project design, materials procurement and actual construction activities (Tongo, et al, 2020).…”

Construction and Demolition Waste Management in a Developing Country: A Nigerian Scenario

“…Regarding the factors that influence waste generation in building projects in southwestern Nigeria, determinants such as lack of early contractor involvement, undefined project brief, poor design quality, last-minute client requirements, frequent design changes and poor design, and engagement of inexperienced designers were found to be the most important factors [34]. In the south-south region of Nigeria, a study investigated the level of construction material waste generated on building sites to empirically establish the level of waste generated on building sites and compare such with the allowable value in estimates.…”
