Resumo
Em Angola, não se encontram estabelecidos nem definidos critérios de medição de trabalhos de construção aplicáveis às obras públicas e/ou particulares. Essa indefinição, quer normativa quer de cadernos de encargos, tem frequentemente conduzido à existência de conflitos entre diversas entidades intervenientes nos empreendimentos de construção e, consequentemente, a desvios de custo, de prazos e da qualidade nas obras.
É incontornável a influência histórica que o setor português de Arquitetura, Engenharia e Construção (AEC) tem tido em Angola, pela presença e representatividade das empresas portuguesas na conceção, execução e gestão de obras em Angola. Por isso, justifica-se estudar e ter presente a boa experiência portuguesa, brasileira e de outros países nesse setor e, em particular, a forma como tem definidas e têm aplicado as regras de medição de trabalhos de construção de edifícios.
Esta dissertação insere-se na linha de projetos de investigação que o Laboratório Nacional de Engenharia Civil (LNEC) tem desenvolvido, tendo por objetivo propor uma estrutura de modelo de regras de medição de trabalhos de construção de edifícios que seja ajustado à realidade de Angola.
Para atingir os objetivos propostos, fez-se uma idenficação e uma análise comparativa dos vários documentos de referência internacionais sobre medição de trabalhos de construção, nomeadamente quanto ao tipo de estrutura dos seus modelos, aos conteúdos das regras contidas neles e às formas como estão organizadas nos respectivos modelos (organização por capítulos e/ou artigos). Foram realizadas entrevistas ao meio técnico e empresarial do setor AEC angolano e analisada documentação técnica por eles disponibilizada, com o intuíto de registar a sua experiência e as sugestões relacionadas com a aplicação de critérios de medição de trabalhos de construção. Com base no cruzamento dessa informação, é proposta a estrutura de um modelo de regras de medição de trabalhos de construção, aplicável à fase final de projeto, à orçamentação e à execução de obra, ajustado à realidade e necessidades de Angola.
In Angola, no measuring criteria for construction works applicable to public and / or private works are established or defined. This lack of definition both of regulations and specifications has frequently led to conflicts between various entities involved in construction projects and consequently to deviations in cost, deadlines and quality in the works. It is unquestionable the historical influence that the Portuguese Architecture, Engineering and Construction (AEC) sector has had in Angola, taking into account the presence and representativeness of Portuguese companies in the design, execution and management of works in Angola. For this reason, it is justified to study and bear in mind the good Portuguese, Brazilian and other countries experience in this sector, and in particular the way in which it has been defined and has applied the measurement rules for building construction work. This dissertation is part of research projects that the National Laboratory for Civil Engineering (LNEC) has been carring out, aiming at proposing a general model of measurement rules for buildings construction works that is adjusted to the reality of Angola. In order to achieve the proposed objectives, an identification and comparison between the various international reference documents on the measurement of construction works is done, namely considering the structure types, the contents of the rules and the ways in which they are organized (Chapters and / or articles). Interviews were conducted with Angolan AEC sector technicians and companies and the technical documentation provided by them was analysed, with the purpose of recording their experience and suggestions related to the application of measurement criteria for construction works. Based on this information, the structure of a model for measurement rules of construction works is proposed, applicable to the final stage of the design phase, to the budgeting and to the construction works execution, adjusted to the reality and needs of Angola.
