“…These other two graduate students together with the first observer were used as independent observers to determine the reliability by calculating the average error of their end results by formula: standard deviation of safety indexes multiplied by one hundred and divided by the mean of the safety indexes (Laitinen et al, 1999). The average percentage error was found to be 2% as shown in Table 3.1.…”

The construction work environment remains one of the most hazardous worldwide. As a result of dangerous working environments, construction workers often face safety and health risks throughout the construction process. However, it is worth noting that an emphasis on construction safety has increased mainly in the aspect of safety performance, and efforts are required to not only monitor but also seek to improve safety performance. The main objective of this research is to assess safety performance on construction sites using safety activity analysis technique. A safety activity analysis framework as well as a safety activity analysis tool are developed to facilitate the collection and analysis of the safety activity data for continuous evaluation of safety performance.Additionally, a case study is carried out to implement the framework and tool on an active construction project. Activity observation is used to continuously collect data of safe behaviors and conditions, along with unsafe behaviors and conditions on construction sites for analysis and decision making. It is expected that the observation results can be used to set improvement targets and provide continuous feedback so that construction workers can adjust their performance accordingly. The findings of the case study show that the safety index of the construction site ranged from 37.0% to 62.8% with an average of 53.8%. Results obtained also indicate that the stage of a construction process can affect the safety performance of a project. It was recommended that well-informed decisions and far-reaching efforts have to be made to ensure the safety index is brought as close as possible to 100% by reducing the unsafe behaviors and conditions on the construction site.iii

ResumoA segurança ocupacional é imprescindível na indústria da construção civil e a análise e avaliação de riscos para a segurança ocupacional (AARSO) é o primeiro e fundamental passo para alcançá-la, baseado na definição e implementação de programas de prevenção. A AARSO é um processo complexo, que implica a consideração e análise de muitos parâmetros quantitativos e/ou qualitativos que são difíceis de quantificar. As metodologias AARSO utilizadas na indústria da construção civil são baseadas em informação sujeita a incerteza (sendo tratada por técnicas probabilísticas e/ou estatísticas), difusa, imprecisa e/ou incompleta. Isso implica algumas limitações, como, por exemplo, obrigar os analistas a estimar parâmetros ou efetuar comparações com outros canteiros de obras (o que afasta do sistema real em estudo). O objetivo inicial deste estudo foi efetuar a pré-validação de um método AARSO, o QRAM, em duas cidades brasileiras, de médio e grande porte. (SILVERSTEIN et al., 1998;DONG et al., 2007;CAMBRAIS;SAURIN;FORMOSO 2008). Palavras-chaveA integração dos requisitos de segurança na etapa de desenvolvimento de produto (projeto) parece ser uma das alternativas com maior potencial de criar benefícios, uma vez que pode eliminar ou reduzir os perigos nas suas origens, dado que as falhas de projeto são uma das mais importantes categorias de causa-raiz dos acidentes nessa indústria (SAURIN, 2005).A análise e avaliação de riscos para a segurança ocupacional (AARSO) é o primeiro e fundamental passo para alcançar essa integração, permitindo a definição e implementação de programas de prevenção logo no início da construção.Diversos estudos (DEDOBBELEER; BELAND, 1991;RINGEN et al., 1995;GILLEN et al., 1997;LAITINEN;MARJAMAKI;PAIVARINTA, 1999;LOOSEMORE;LEE, 2001;TAM;ZENG;DENG, 2004) identificaram algumas das causas que afetam o nível de segurança em canteiros da construção civil, das quais se destacam:• Inadequada organização do trabalho;• Inadequada gestão da segurança;• Falta de formação, informação e sensibilização;• Fraca cultura de segurança;• Falta de coordenação e de supervisão;

“…New proactive safety methods have recently been introduced at construction sites in order to reduce high injury incidence rates [Laitinen et al, 1999a]. Questionnaires, interviews, safety audits, and safety walkarounds are often used to supplement injury rates in evaluating different safety dimensions at the site: the safety climate, the organizational safety standard, and the safety standard of the physical working conditions.…”
