Considering that, in Pernambuco, Development Regions (RD) were created for the planning and implementation of Multi-Year Plans (Plano Plurianual - PPA), as determined by the Constitution, this work aims to analyze the extent to which the implementation of the PPA has contributed to the promotion of regional development in the context of the State of Pernambuco. For this purpose, the DR Mata Sul was selected, due to its potential, and the PPA/PE 2020-2023. The methodology involved the following steps: a) bibliographic review of theoretical frameworks which deal with region/regionalization within the field of knowledge of Geography, highlighting the “planning region” as a normative instrument for state action; and some concepts involving public policies; b) documentary research of legislation and other government instruments that deal with DRs-PE and the PPA; c) data collection for the sociodemographic and economic characterization of DRs-PE, particularly the DR Mata Sul/PE; and d) qualitative analysis of the harvested data, especially those from DR Mata Sul/PE, relating them to the theoretical framework. The results obtained suggest that the regionalization adopted in Pernambuco contributes to the planning and execution of public policies. However, more detailed studies must be carried out for a more precise characterization of the regional inequality among the RDs.

The main objective was to evaluate the effectiveness of the method in correcting pathologies, such as cracks and differential settlements, which originated from failures in soil compaction and construction defects that compromised the structural stability of the building. The methodology adopted included a literature review, analysis of technical reports and project plans, and visual inspections in the field to diagnose the anomalies. The execution process of the recovery consisted of injecting cement grout under controlled pressure to fill voids and improve the bearing capacity of the soil. The results, verified through monitoring of the structure after the intervention, demonstrated the stabilization of settlements and the mitigation of pathologies, confirming that the technique significantly improved the geotechnical characteristics of the soil. It is concluded that cement grout injection proved to be an effective and viable solution for ensuring the safety and stability of the foundation, serving as a practical reference for structural rehabilitation projects in similar contexts.

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 Mon, 09 Feb 2026 00:00:00 GMT https://repositorio.ifpe.edu.br/xmlui/handle/123456789/2099 2026-02-09T00:00:00Z https://repositorio.ifpe.edu.br/xmlui/handle/123456789/2093 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.
