Preparation of Environmental Management Plans (PGA) and Construction and Demolition Waste Prevention and Management Plans (PPGRCD) in the design and construction phases.

The main objectives of the PGA are as follows:
Ensure compliance with applicable legal, regulatory and / or normative requirements;
Comply with what is defined in the Specifications;
Assess the significant environmental impacts resulting from the construction phase and define minimization measures;
Assign responsibilities to the various entities involved in the process, through the definition of environmental management procedures;
Promote the reduction and reuse of waste generated, as well as the rationalization of consumption of raw materials;
Promote the application of the best environmental practices;
Prevent situations of environmental risk;
Define Monitoring, Measures and Verification Plans and Programs necessary for the control and protection of the environment;
Promote the awareness of all employees and subcontractors to the responsibility of preserving and protecting the environment, ensuring appropriate training and education for each function.

The main objectives of the PGR are as follows:
Identify and classify the waste produced during the construction phase;
Recommend management measures to be adopted and the final destination to be given, depending on the type of waste, seeking, whenever possible, destinations for recovery, reuse and recycling, to the detriment of controlled disposal.
