Difficulty in meeting the consumption items criteria was found . Despite data on water and energy consumption having been collected on a monthly basis , the dissemination of these onto workers was not a routine . Often the storage of materials was also not appropriate . From the material purchase viewpoint , the project team faced difficulties in finding material factories near to the city of Salvador , such as high flag ash cement , ceramic tiles , aluminum composites and glass . It is therefore necessary to incentivize local industries .
Due to a structured waste program under an external consulting , almost 80 % of the practices were systematically implemented during the study . One of the difficulties was concerned with plaster waste , as despite the obligation imposed by CONAMA Resolution N . 307 ( CONAMA 2002 ), there is to date , no industry to receive plaster residue in Salvador , so it is was sent to a dangerous waste landfill . Another important consideration is that waste management requires continual monitoring and training in order to ensure correct segregation . Often waste was found mixed together therefore requiring more bins located in strategic work areas to promote reuse within the jobsite . At times subcontractors showed a resistance in adapting to the contractor sustainable construction policies . Even with daily training on waste management and other practices emphasizing importance , the construction site had some difficulties in making the workers participate , due to the high employee turnover . Contact was made with the subcontractor managers to enforce employee commitment , thus confirming the need to determine measures and include previously agreed contract terms guaranteeing adherence to best practices and project policies when hiring subcontractors .
Concerning pollution , an evolution in the implementation of good practices until September 2013 was noted . The recurrent problems identified were the non use of plastic construction safety nets and often the production team did not wet areas during production activities and when sweep-
