Resumo
The main goal of this research is to check how the forensics labs from Brazilian Federal Police follows the recommendations offered by the Forensics National Institute with respect to the physical environment, as well as its implication to the interdisciplinary iteration between experts and to the chain of custody of the evidence. The theoretical basis of this study relies on the knowledge of interdisciplinary, chain of custody, layout in process management and space planning. The research was conducted with data collected from questionnaires submitted to the appropriate sectors, technical documentation produced by the Brazilian Federal Police and additionally with field data collected during technical visits to the forensics labs of Paraná, Santa Catarina, Espírito Santo, Goiás, Alagoas, Rio Grande do Norte e Amazonas, which covered both general and regional aspects. Two different recommendations offered by the Forensics National Institute were identified: the first one concerns the preliminary phase of the building project and the second one is offered in a later moment, during evaluation phase, and it is performed by different work groups. Different opinions regarding the physical environment and facilities of the forensics labs from all over the country, which formed the foundation basis for the proposal of improving the physical arrangement in the forensics unit where the researcher works, as well as to record its subsequent implementation. By comparing the recommendations with the field data, it was possible to identify communications gaps inside the National Forensics Institute itself, which implied in losing opportunities to provide updated information on physical environment to the project designers. Despite the recent advances in this topic, concerning the creation of the forensics units layouts and the creation of committees for the Forensics Management Evaluation, it was concluded that the National Forensics Institute should keep an integrated management system of such information, which should be aligned to the new project and construction trends of the Federal Government, in order to continuously update the system database, transforming the field observations into new guidelines and recommendations.
