Aprimorando a gestão da seleção tecnológica na construção civil: estudo exploratório em Belo Horizonte

Abstract

An exploratory research was conducted in order to highlight the importance of introducing and managing new considerations in the selection and evaluation of housing construction systems - including aspects not measurable in lab tests. The analysis was based on a case study conducted in 2015 with professionals working in Belo Horizonte, in order to investigate the assumptions to be used in the technology decision-making process when searching for an expanded idea of performance. The first step consisted in defining a list of requirements and criteria to be taken into consideration for the construction of multi-family housing. They were identified through literature review and semi-structured interviews with a group of experts, or "calibration group", representing the decision makers. In a second moment, the researchers proposed questionnaires to various stakeholders involved in the construction of multi-family residential buildings to assess the relevance of these requirements and criteria, according to each of them. Through these questionnaires and open interviews, it was possible to determine five priority themes: adequacy of the construction system to the concept of the project; generation of waste; economic adequacy during construction; designer´s knowledge of technology; and economic adequacy during the use phase of the building. Furthermore, the results allowed identifying issues that may be the source of conflict in decision-making. They also revealed a need to improve knowledge about important points of the conjuncture that involves each theme, in order to build a more shared vision. According to the discussion, the preliminary stages of the multicriteria analysis - hich includes the definition of requirements and criteria - can help in this process. In this way, the research highlights the need to promote a collective learning process and build a shared vision that benefits not only the entrepreneur, the user, or other agents, but, ultimately, society.
