This study focuses on the problems associated with the traditional practice of reducing costs in construction and the need to increase business competitiveness in the residential real estate sector. In this context, target costing is a promising approach to improve the competitiveness of companies by ensuring that the products launched on the market do not jeopardize the company's results and value delivery to customers. However, far too little attention is paid to target costing implementation by companies that develop residential real state products for sale and face strong market competition. Thus, this paper seeks to investigate whether the standard framework of target costing in the literature applies - with or without adjustments - to real estate developers. Case study was the research strategy adopted. Guidelines are proposed for the introduction of target costing in the development process of residential real estate products. The proposed guidelines are related to the three main sections of the target costing process: market-driven costing, product-level target costing and component-level target costing.

Brazilian construction companies have sought lean thinking to increase competitiveness in the sector. The initial step for lean implementation is to stabilize the project production system. Many lean tools have been applied to stabilize production, however daily managemet is a lean practice that has been implemented in manufacturing and has little application in the construction. This paper aims to explore daily management in the construction context and evaluate the results of its implementation. Action research was the research method adopted. The research lasted three months and was conducted in three stages: the first for preparation, the second for the implementation cycles and the final for analysis and conclusions. The application evaluated the four fundamental elements of daily management: visual management, teamwork problem solving, help chain, and leadership. Daily management implementation facilitated decision-making and problems were solved more often and in a more structured way with the help chain. Visual boards helped the managers to see the production and productivity deviations. Meeting routines provided a more present leadership in the field and a spirit of team collaboration. The main results of the research were the reduction of project costs, project completion on time and increased project team commitment.

The use of production cells in manufacturing has achieved many benefits, motivating researchers to apply them in the construction environment. The aim of this research is to identify time, space, and information linkages in construction's production cells applications, seeking opportunities for broader implementations. We adopted a literature review approach focusing on cases in the Brazilian construction sector that addressed cell applications. Subsequently, comparative tables of these publications were prepared, analyzing the consideration of time, space, and information linkages, as well as identified results. The article pointed out that there is a gap in publications that address the application of a production cell in almost all construction flows, except the job site flow, reflecting the tendency of most companies of applying lean concepts firstly in physical flows. By analyzing these aspects (group of features that enhance the use of the cell), it was found that "material flow and pull systems" and "operators interaction" were the aspects most often considered, but mostly partially. Few cases reported the use of "flexibility" and "equipment maintenance". No case reported comprehensive considerations of the three important linkages of time, space, and information. Space was the linkage better considered compared to time and information linkages. Lead time reduction, cost savings and increased productivity were among the greatest benefits reported from the applications of production cells. There is also a positive correlation between the linkages coverage and the number of benefits obtained. Further research is suggested in order to investigate the results of a more comprehensive application considering all linkages.

O custo tem um impacto significante não só no processo de projeto, mas também na solução arquitetônica apresentada. O Target Value Design (TVD), pode se apresentar como uma abordagem promissora para direcionar o processo de projeto pelo custo e pelas percepções de valor do cliente ou usuário final. Esta pesquisa almejou disseminar conceitos do TVD junto a agentes participantes na gestão do processo de projeto de empreendimentos imobiliários e contribuir para a reflexão teórica sobre a sua adoção neste meio. O método de pesquisa consistiu em simulações-piloto em meio acadêmico para adaptações iniciais e simulações posteriores em empresa de incorporação imobiliária. As simulações se deram em duas rodadas, a primeira simulando o ambiente tradicional de Design-Bid-Build (DBB) e a segunda utilizando o TVD. Os resultados provenientes da segunda rodada (TVD), onde foi imposta uma restrição de custo, acabaram levando a uma aparente simplificação do modelo. O TVD demanda mudanças no processo de projeto, e uma das mais desafiadoras é considerar o custo como parâmetro de entrada no processo, em vez de ser uma mera consequência do mesmo.

A integração entre Interface de Programação de Aplicativos (API) e a Modelagem da Informação da Construção (BIM) possui grande potencial para facilitar a quantificação de resíduos na construção civil desde a fase de projeto. Deste modo, observa-se a possibilidade de uso de APIs para produzir informações de grande relevância para o fomento da economia circular (EC) na indústria da construção civil. Esse artigo comparou dois APIs e avaliou seus potenciais de uso para fomento dos princípios da EC no setor. O método adotado foi o mapeamento sistemático da literatura seguido de análise comparativa de dois APIs identificados na etapa anterior. A principal similaridade entre as APIs encontra-se no fato de ambas terem sido desenvoldidas para o software Autodesk Revit. A principal diferença está no uso das APIs em distintas etapas do ciclo de vida da edificação. Os resultados sugerem a necessidade de estudos que estendam a integração de APIs a diferentes softwares BIM.
