Critical practices for implementing risk management in projects in micro and small companies in the construction sector in southeastern Brazil/Praticas criticas para a implantacao da gestao de riscos em projetos nas micro e pequenas empresas do setor de construcao civil no sudeste do Brasil/Practicas criticas para la implementacion de la gestion de riesgos en proyectos en micro y pequenas empresas del sector de la construccion en el sudeste de Brasil

Project risk management (PRM) is widely used worldwide. In Brazil, this knowledge is still little applied by a portion of professionals working in the construction sector, in micro and small enterprises (MSEs), which are important for the economy. The objective of this article is to identify the critical practices for the implementation of PRM in MSEs in the construction sector, in the Southeast of Brazil. In this study, a questionnaire with 25 assertions about PRM practices was developed and sent to 153 professionals, with 79 valid responses. The Expectation Maximization algorithm and the Normalization Test were applied, using SPSS 21.0 and EXCEL software. The results were normalized to identify the critical practices. Of the total of 25 practices, 6 of them had normalized importance values equal to or greater than 80%, showing that these practices are very important for PRM. All practices of hypothesis H1: "Project Management practices assist in the implementation of PRM in MSEs" were fully confirmed, since the normalized results of the practices that make up this group were greater than 0.5. The other hypotheses (H2, H3, H4 and H5) were only partially met. Most of the professionals who contributed to this work recognize the relevance of PRM for civil construction projects, which may contribute to improving the performance of MSEs. Keywords: Civil Construction. Project Risk Management. Risk Management. Management Control. Sustainability. A gestao de riscos em projetos (GRP) e largamente utilizada em todo o mundo. No Brasil, este conhecimento ainda e pouco aplicado por uma parcela de profissionais que atuam no setor da construcao civil, em micro e pequenas empresas (MPEs), que sao importantes para a economia. O objetivo deste artigo e identificar as praticas criticas para a implementacao da GRP em MPEs do setor de construcao, no Sudeste do Brasil. Neste estudo, foi desenvolvido um questionario com 25 assertivas sobre praticas de GRP, que foi enviado para 153 profissionais, sendo obtidas 79 respostas validas. Foram aplicados o algoritmo Expectation Maximization e o Teste de Normalizacao, por meio dos softwares SPSS 21.0 e EXCEL. Os resultados foram normalizados para identificar as praticas criticas. Do total de 25 praticas, 6 delas tiveram valores normalizados de importancia iguais ou maiores que 80%, mostrando que essas praticas sao muito importantes para a GRP. Todas as praticas da hipotese H1: "As praticas de Gerenciamento de Projetos auxiliam na implan
