Análise financeira para requalificação de vias urbanas baseado no custo de ciclo de vida: o impacto da manutenção preventiva em pavimentos intertravados Urban pavement management in Brazil is characterized by a reactive intervention culture, which leads to high public expenditures and premature infrastructure obsolescence. This study proposes a financial analysis of the impact of preventive maintenance on interlocking concrete block pavements, based on Life Cycle Cost (LCC). The methodology included the design of a reference cross-section, cost assessment using SINAPI data, and the simulation of two scenarios over a 20-year horizon: Scenario A (preventive maintenance every three years) and Scenario B (major corrective maintenance in the 12th year). The results indicate that the preventive strategy presents a net present value of R$ 188,440.20, making it 15.86% more cost-effective than the reactive strategy (R$ 218,318.32). It is concluded that low-cost interventions, such as joint refilling and manual sweeping, are strategic investments that ensure structural stability and the financial sustainability of public managemen

Proposta de implementação da construção enxuta em uma empresa de pequeno porte The construction industry has historically presented high levels of waste, rework, and low productivity, largely resulting from the lack of structured planning and systematic management practices. In this context, Lean Construction emerges as an approach capable of promoting significant improvements in project performance. This article aims to analyze the application of Lean Construction principles in a small-sized construction company, referred to in this study as União Engenharia Ltda. (fictitiousname), through a case study. The methodology is characterized as an exploratory qualitative research, supported by descriptive quantitative analysis, based on a literature review, direct observation, semi-structured interviews with key employees, and a questionnaire survey. The results reveal problems related to material waste, rework, lack of standardization, communication failures, and absence of formal planning. Based on the analysis, recommendations grounded in Lean Construction principles and Production Planning and Control (PPC) are proposed, aiming at continuous improvement and increased production efficiency.

Tijolos de adobe e alvenaria racionalizada: sustentabilidade e otimização na construção de habitações populares em assentamentos rurais Civil construction plays a central role in socioeconomic development; however, it is responsible for significant environmental impacts and high consumption of natural resources. In this context, this study aimed to investigate the application of adobe bricks associated with the principles of rationalized masonry in the production of socialhousing in rural settlements. The research adopted a qualitative and applied approach, based on a bibliographic and normative review, with emphasis on ABNT NBR 16814:2020, in addition to the development of a case study through the modeling of a rationalized masonry project using computer-aided design software. The results demonstrate that adobe, by using local raw materials and not requiring a firing process, presents significant potential for reducing environmental impact. When combined with rationalized masonry, the system contributes to reduced material waste and greater construction efficiency. Therefore, it is concluded that the association between the use of adobe and rationalized masonry techniques constitutes a viable alternative for the construction of social housing in rural areas, aligned with sustainability guidelines and contemporary social demands.

Desafios da gestão de obras de reforma de médio a alto padrão em apartamento na RMR The management of medium- to high-standard apartment renovation projects in the Metropolitan Region of Recife (MRR) presents specific challenges when compared to new construction, as these works take place in existing and occupied buildings. This study aimed to analyze such challenges through a multiple case study, adopting a qualitative, exploratory, and descriptive approach, based on participant observation in three renovation projects carried out between 2022 and 2024 by a small-sized company. Data collection included on-site monitoring, analysis of executive design documents, technical records, photographic documentation, institutional communications, and the use of a digital project management tool, articulated with normative and bibliographic references. The results revealed recurring issues related to outdated infrastructure, low levels of project coordination, condominium operational constraints, communication shortcomings, and information management. It was found that the adoption of mitigation strategies—such as rigorous initial technical diagnostics, design coordination checklists, room-based schedules, formal records, and centralized information management—contributes to reducing conflicts, rework, and uncertainty. The study concludes that, in this context, the civil engineer assumes an expanded role as a multidisciplinary coordinator and risk manager, with structured communication and continuous control being decisive factors for project performance and quality.
