Abstract
Research outcomes all over the world have indicated that the building production sector of the construction industry relates more to the environment than other sectors of the economy and is directly involved with its sustainable activities in terms of waste generation and balancing the outcome has further been enhanced through industrial revolution time. The main aim of the study, therefore, was to carry out research on issues and challenges that revolve around contractors’ attitudes towards maintaining a controlled environment on construction sites. A mixed research design method that involved the quantitative and qualitative analysis was used for the study, while the samples were picked with a random sampling method. The total sample size of respondents is 100 questionnaires which were randomly selected for questionnaire administration to selected construction firms in Lagos state. The questionnaires were administered to professionals from different firms in Lagos State, Nigeria. A total of 100 questionnaires were distributed in this review while 92 questionnaires were duly returned by the respondents, which constitute 92% of the total questionnaires distributed. The categorical regression method was used in the analysis. ANOVA, Chi-square, and factor analysis were used for the analysis. The study discovered among other things that the following components of environmental sustainability are important to sustain on sites: environmental impact assessment, antiquities on-site, erodible surface, soil erosion monitoring, environmental ecosystem, and environmental biomass, rock mass found on-site, soil contamination monitoring and ecosystem services valuation, soil salinity monitoring, and water resources conservation. The study concludes by recommending that the design of an effective way of disposing of waste on-site and continually improving construction methods and procedures to enhance performance in achieving a sustainable environment are vital to sustaining a viable construction environment among other factors.
Highlights
The study attempted to respond to some of the emerging questions in the study, including: What is the perception of Nigerian contractors regarding environmental sustainability? What is the component of an environmental portfolio that should be sustained on construction site? What strategies can be used for maintaining environmental sustainability on-site? Is it possible to develop a framework for site environmental sustainability?
What is the component of an environmental portfolio that should be sustained on construction site? What strategies can be used in maintaining the environmental sustainability on-site? Is it possible to develop a framework for site environmental sustainability?

Summary
As regards the background of the study, sustainability is most often defined as meeting the needs of the present without compromising the ability of future generations to meet theirs It has three main pillars and parameters: economic, environmental, and social. Sustainability: Meeting our present needs without compromising the ability of future generations to meet their own needs [3] It has three components, which include environmental conservation, social responsibility, and economic development. Social sustainability focuses on maintaining and improving social quality with concepts such as cohesion, reciprocity and honesty and the importance of relationships amongst people It can be encouraged and supported by-laws, information, and shared ideas of equality and rights. This study has contributed to the body of knowledge by developing the component of an environmental portfolio that should be sustained on construction sites, the presentation of strategies that can be used in maintaining the environmental sustainability on site, and development of a framework for construction site environmental sustainability
