Although all assessment methods show differences within their methods of criteria evaluation and their categories, it can be seen that all criteria fall under similar themes, forming a flow system related to inputs and outputs( consumptions and emissions) within the physical, biotic and anthropic context of the construction enterprise, and its relationship with the external and internal environment, according to Degani’ s( 2003) classification.
However, there is a lack of knowledge on the available solutions, technologies and procedures involved with their employment on construction sites. It is also necessary to know the minimum conditions, legislations and resources required to deploy solutions after performing a technical and economic feasibility study based on the particularities of the construction site, specific production activities, logistics, financial constraints and human resources.
Therefore, the objective of this paper is to present the deployment of sustainable practices aimed at mitigating the environmental impacts produced during the construction process, based on a case study on the New Headquarters of the Construction Chamber for the state of Bahia( Sinduscon-Ba), Brazil. In order to propose this implementation, information obtained from a literature review on the guidelines suggested by the environmental assessment methods and from a previous work( Guimarães, 2013, Thomas et al., 2013), which aimed to identify priority needs for sustainable solutions for construction site developments were taking as a basis.
Research Method
This work was developed using the case study strategy, which was conducted on the construction site of the New Sinduscon-Ba Headquarters. The aim was to adopt best practices for deploying a low environmental impact jobsite which involved the following three stages:( a) Identification and selection of best practices,( b) Implementation of best practices,( c) Monitoring, Learning and Remedial Actions. From this, a generic methodology for implementation of sustainable construction jobsites was developed through applying the concepts of continuous improvement whilst implanting and monitoring best practices, which is however, not the focus of this paper.
Identification and selection of best practices The identification of possible best practices to be implemented was based on the literature review related to the environmental assessment methods, previously presented at Table 1, and from the findings of a survey about sustainable best practices on construction sites applied in Brazil by Guimarães( 2013) and Thomas et al.( 2013). Specifically, good practices on solid waste were based on the National Environment Council( CONAMA) Resolution 307, which establishes directives, criteria and procedures for the management of waste from building construction in Brazil( CONAMA, 2002). Good practices on Health and Safety were based on NR-18 standards( Regulatory Standard-18- Working conditions and the environment in the Construction Industry in Brazil)( Ministry of Labor and Employment – MTE, 2013). Air pollution practices were based on the London Council publication( 2010).
The selection of good practices and solutions to mitigate the environmental impacts of the Sinduscon-Ba Building was carried out through weekly progress meetings during the first six months of the project with the project team, including the project engineer, general contractor, the project and environmental manager and the owners( Chamber CEO and Project Director), and afterwards through monthly meetings and video conferences with the AQUA consultancy company to validate the practices selected. The following evaluation criteria were adopted to assist in the selection of practices and solutions:
