Abstract
The activities of the construction industry are often plagued with improper material control and operational measures that result in the production of noise and generation of waste in project sites. Waste and noise are generated in every step of the construction process, from the production of materials used, to the erection and finishing of structures. In this age of incorporating sustainability into the development of buildings and their environments, there is a need for the construction industry to substantially reduce the amount of noise and waste produced. This paper investigated various noise pollution and waste control techniques used in the construction industry in Nigeria, with a view to identify areas for further improvement. The paper is a systematic literature review which made use of document analysis to collect data and content analysis to analyse the data gathered. Descriptive approach was used to present the result. The paper examined the current state of waste and noise management and the recommendations provided. The study found that in Nigeria, the noise control technique employed is the use of noise barriers, while the waste control management strategies used are prefabricated elements, sorting waste generated, open dumping, open burning and composting disposal method. Some of the recommendations made include: discarding open dumping and open burning as waste control measures due to their negative environmental impact, developing and enforcing a legal framework for noise and construction waste. Furthermore, educating site workers on noise and waste control techniques and replacing machines that use combustion engines with those that use electrical motors. Students, educators, building industry practitioners and other construction industry stakeholders will find the study a useful material to work with, as well as build upon.
Highlights
The role of the construction industry is notably significant when it comes to a nation’s economic development
The result shows the sources of waste construction and noise pollution are from the equipment used and the activities employed on the construction site in addition to mistakes and unnecessary movements
The results showed the negative impact construction waste has on cost and the damaging effects of construction waste and noise pollution on the environment and other control techniques
Summary
The role of the construction industry is notably significant when it comes to a nation’s economic development. The activities of the construction processes generate noise and waste which pose a severe threat to the environment. Their effects happen over time, from crude materials being processed, to their utilization in construction, to the maintenance and demolition of the structure [4]. Most of the techniques available for noise pollution and waste control in Nigeria are used sparingly, while some of the control strategies that are being used have been dropped by developed countries due to their unsustainability, negative impact on the environment and having a damaging effect on the wellbeing of the public and workers on construction sites. This paper identified the sources of noise pollution and waste generation in building construction and the various techniques of controlling them in Nigeria, in order to identify areas for further improvement. The result was grouped in themes and presented using descriptive approach with the aid of a table and diagram for better understanding
