Thus, it is necessary to pay attention to environmental issues in this sector (CARNEIRO, 2010). Considering the importance of the construction industry in the productive and industrial chain in Brazil, to take action and/or implement sustainability strategies, especially in construction sites, is presented as a key factor for reducing environmental impacts from this activity (SILVA & PORANGABA, 2012). This study aims to propose the implementation of sustainable actions in a construction site, based on existing legislation and standards, through a case study. The chosen project is in the construction phase, located in Natal / RN. The methodology started from a diagnosis through technical on-site visit with photographic record, access to documents and projects and interviews with managers of the work to know the main environmental aspects and impacts of processes carried out on site. Through the database there was a survey of the proposed actions costs based on the necessary infrastructure and National Costs and Indexes of Construction Research System (SINAPI). The main environmental aspects that occurred in the site are related to the generation of solid waste, water and electricity consumption. Proposals for sustainable actions include the management of waste according to Resolution No. 307/02 of CONAMA, including material donation to recycling cooperatives; adoption of water reuse for less noble purposes; and environmental education of employees to reduce the consumption of other materials and reduce waste. The costs for implementation of the necessary infrastructure to carry out such actions is R$ 9,042.23. It is suggested for future studies to be evaluated the investment return and the economic feasibility of adoption of such solutions.openAccessaspectos ambientais; impactos ambientais; ações sustentáveis; construção civil.environmental aspects; environmental impacts; sustainable actions; construction.bachelorThesis
