Proposta de estruturação do departamento de custos de uma empresa de construção civil de médio porte

This work consists of a literature review of technical project management with a focus on cost management in order to establish concepts and build a theoretical basis for later perform a case study of a construction company. All of the literature review is based on best practices in project management from the Project Management Institute - PMI, among other bibliographies that use the same concepts. The case study covers issues such as area of expertise, constructions undertaken, methodologies, procedures, assumptions, allowing to understand how the company operates in the market and, especially, which interfaces with the cost department in company processes. Confronting the knowledge gained from the literature review of the concepts of PMI and the information obtained from the case study on the current situation of the management costs of the company, it was possible to identify some gaps in the company processes of cost management and thus propose the solution of creating a centralized functional area focused on cost, that is responsible for ensuring that best practices in project management, specifically costs, are being applied

Adoção de práticas da produção enxuta na construção civil

The civil construction sector has been stimulated to industrialize itself by the adoption of lean production practices in its constructive process. Given this fact, this research verify and identify good practices and difficulties in implementing lean production in construction companies in the State of São Paulo, in order to be able to formulate recommendations to potentiate the performance of the lean concepts applied. The research method used was a multiple case study, where the companies analyzed are constructors that have already initiated the lean application in their systems. From the results, a case analysis was conducted in order to note the constructors' situation in relation to lean construction and, base on this analysis, recommendations were proposed for the companies reflect on lean principles and apply them along to your construction management

Impacto da ABNT NBR 15575 na qualidade da construção civil

The quality in construction is increasingly a concern in this sector, in view of the occurrence of problems in civil works, even when a contractor is certified by ISO 9001. The ISO 9001 certification does not ensure the maintenance of quality because it only establishes the requirements for a quality management system (QMS) to ensure standardization of processes and products. With the development of ISO 15575, standard performance, the builders took on a quality parameter with the requirements established by this Standard, which must be met. Thus, the implementation of a quality management system (QMS) becomes essential, showing users the concern for quality. This study aimed to verify, through a case study, the impact of NBR 15575 quality construction and how that standard of performance may be the key element of ISO 9001 to ensure quality maintenance of civil works

Atualização do conceito de qualidade na construção civil

The quality control is of great importance for the development of any organization, mainly for providing an assurance of delivering high quality services and goods for the consumers. Quality can be defined by the word „change‟, for the company which intends to implement a quality control system must be open to changes. This can be noticed from the JURAN concept (1992 In SILVEIRA ET AL., 2002): “Quality is to fit for usage”, i.e., depending on the goal, the situation and the consumer, quality is seen in different ways, since each one has different wishes and opinions. Taking in to account the availability of means such as norms, theories and tools, that contribute for an efficient quality management system, this discrepancy of opinions and the lack of objectivity of this concept can be solved, since through the analyzes of these means one can set quality standards, i.e., market references which fulfill both consumers and builders demands. Thus, the quality concept ceases to be something so abstract, non-measurable, to become a more objective concept. Finally, the goal of this work is to analyze the quality concept through bibliographic studies and possible consumers‟ enquires, aiming at the building industry, and show how the quality, often taken as something abstract, can be a measurable and objective concept, that benefits both the consumer as well as the enterprise of this branch

Gestão da qualidade na construção civil

Quality Management has become an essential requirement for all companies intending to compete and ensure its place in the labor market. Several tools have been created as a way of ensuring the effectiveness of quality management, in order to control and manage the quality of services and products to ensure a final product with a high degree of competition and quality, besides satisfaction and exceeding customer expectations. Due to the great importance it has at the presente time on the world stage and internationally, civil construction felt the need to eliminate the defects and the lack of quality that have become so common over time to ensure a quality product and it´s customers satisfaction. It was then that this industry began to implement and develop more modern techniques and tools for quality control in construction. Quality achieved position in global market, defining which companies would continue and which companies would leave it, not to mention it became insistently required by the customer. Some tools such as ISO 9000 guided companies seeking a quality management. This presentation will present some of these management tools and their applicability in the civil construction industry. Thus, it will be evident that despite the current resources it is necessary that civil construction professionals abandon the idea that considers quality management a problem and begin thinking about it as a solution to prevent future errors and ensure the quality of their services
