Modelo de supervisión técnica aplicado para viviendas autosostenibles en la comunidad Wayuu de la Alta Guajira, Colombia
(Universidad Santo Tomás, 2026-08-28) Peña García, José Arnoldo; Quintero Cruz, Edwin Ferney; Castro Irreño, Mónica Johanna; Universidad Santo Tomás
This project proposes a technical supervision model aimed at the construction of self-sustainable housing in the Wayuu community of Alta Guajira, with the purpose of strengthening the quality, durability, and sociocultural relevance of housing solutions in this region. The initiative arises from the need to establish supervision guidelines that integrate civil engineering technical criteria, principles of environmental sustainability, and respect for the community’s traditional construction practices. The proposed model articulates planning, control, and work monitoring processes, incorporating the efficient use of local resources, appropriate technologies, water capture and utilization systems, renewable energy, and low environmental impact materials. It also promotes community participation as a central axis of the construction process, ensuring social appropriation of the housing solutions and knowledge transfer. Methodologically, the project is based on documentary review, analysis of previous experiences in sustainable housing, and the formulation of supervision protocols adapted to the climatic, cultural, and socioeconomic context of Alta Guajira. As a result, the project aims to provide a practical tool to guide the work of civil works supervisors in self-sustainable housing projects in indigenous communities, contributing to the improvement of quality of life, habitat sustainability, and local development
Diseño de lineamientos de gestión de proyectos para orientar al sector de la construcción de Vivienda de Interés Social (VIS) en Colombia hacia la implementación del estándar de sostenibilidad EDGE, basados en el PMBOK
(Universidad Santo Tomás, 2026-08-27) Domínguez García, Deiby; Medina Vargas, Luisa Fernanda; Díaz Uribe, Carlos Alonso; Universidad Santo Tomás
Problem: The social housing (VIS) construction sector in Colombia exhibits low adoption of the EDGE (Excellence in Design for Greater Efficiencies) sustainability standard, not because organizations lack interest, but because clear methodologies are lacking to integrate its technical requirements with project management frameworks, within a context of budget constraints, training gaps, and regional heterogeneity. Objective: To design project management guidelines based on PMBOK 7 that enable the implementation of the EDGE standard in VIS projects in Colombia. This will be achieved by identifying current practices and barriers, structuring a set of management practices and deliverables, and formulating a progressive and contextualized adoption roadmap. Method: A mixed-methods approach with a predominantly qualitative focus was employed, using three instruments administered to ten construction companies in Bogotá D.C., Medellín, Cali, and Barranquilla: a structured survey for project managers, a structured survey for HSE coordinators, and a joint semi-structured interview for both roles in five companies. Results: The diagnostic revealed basic and intermediate levels of knowledge about EDGE, four categories of barriers, and a 90% predisposition among the organizations to establish guidelines if support is provided. Discussion: The findings demonstrate that the perceived cost overrun is overestimated in relation to the actual increases recorded, which ranged between 4.5% and 8%. Furthermore, the coordination between project management and the HSE department is the organizational factor that most significantly determines the feasibility of certification. Keywords: EDGE standard, social housing, project management, PMBOK, sustainability in construction
Predicción temprana de brotes de dengue en Bucaramanga mediante un modelo de Machine Learning con integración de variables climáticas, geográficas y sociodemográficas

Problem. Dengue is an endemic arboviral disease in Bucaramanga that accumulated 10,259 cases reported to the National Public Health Surveillance System (SIVIGILA) between 2015 and 2022, with a hospitalization rate of 26.6% and recurrent epidemic peaks. However, the municipality lacks tools capable of anticipating outbreaks. Objective. To develop a machine learning model for the early prediction of dengue outbreaks in Bucaramanga by integrating epidemiological, climatic, geographic, and sociodemographic variables. Methods. A quantitative, applied, and longitudinal study was conducted following the CRISP-DM methodology. Data from SIVIGILA, climate records from IDEAM, Sentinel-2 vegetation indices (NDVI), and sociodemographic indicators from DANE were integrated and aggregated by epidemiological week and administrative district. Five approaches were compared: a seasonal naïve model and ARIMA as baseline models, versus Random Forest, XGBoost, and LSTM. Models were evaluated using a strict temporal split and prediction horizons ranging from one to four weeks. Performance was assessed using MAE, RMSE, MAPE, MASE, F1-score, and AUC metrics, complemented by the Diebold–Mariano test and SHAP-based interpretability analysis. Results. Machine learning models reduced prediction error to less than two-thirds of the naïve forecast and significantly discriminated outbreak weeks (p < 0.001). Temperature, with a seven-week lag, was identified as the most relevant environmental predictor. Outbreak risk was concentrated in the San Francisco, Centro, and Oriental districts, which accounted for 32.4% of reported cases. Conclusions. Dengue outbreaks can be anticipated using publicly available local data. The DengueAlert-BGA prototype represents an interpretable and replicable tool to strengthen epidemiological surveillance and public health response in the municipality.
Análisis Comparativo de Marcos de Gestión de Proyectos en Construcción de Obras de Mitigación de Fenómenos de Remoción en Masa en el área metropolitana de Bucaramanga, frente al PMBOK Sexta Edición: Identificación de oportunidades de mejora.
(Universidad Santo Tomás, 2026-08-27) Rivero Amorocho, Laura Andrea; Quijano Machuca, Mario Hernando; Universidad Santo Tomás
The civil works construction sector for the control and mitigation of mass wasting phenomena represents a critical area of intervention in Colombia, particularly in the Bucaramanga metropolitan area. This research aimed to conduct a comparative analysis of the project management frameworks used in this sector against the guidelines of the PMBOK Sixth Edition, in order to identify opportunities for improvement in project management. The study was developed using a qualitative approach, employing a multiple case study design that combined document review, analysis of SECOP contract documents, and semi-structured interviews with four professionals in the sector, triangulated to ensure the validity of the findings. The results showed that the sector has a hybrid and informal approach, with a high degree of geotechnical technical capacity, but with structural weaknesses in the managerial dimension, specifically in integration, risk management, stakeholder engagement, and resource allocation, with low alignment with the PMBOK. Based on these results, an improvement plan was defined, proposed across three intervention horizons, which envisions a gradual and contextualized incorporation of the standard. This research offers novel empirical evidence on project management practices in the sector, considered key to risk management in the region.
Diseño de un plan de implementación de Gobierno Corporativo para la Gestión de Proyectos en la Fiscalía General de la Nación en el marco del Convenio de Cooperación (FGN-PONAL-Ecopetrol-CENIT 2025–2028) usando PPM–PMI, PRINCE2 e ISO 21500, orientado a fortalecer la capacidad institucional.

Copilot said: The study aimed to design a corporate governance implementation plan for the management of the FGN–PONAL–Ecopetrol–CENIT Cooperation Agreement 2025–2028, with the purpose of improving planning, resource execution, and compliance with the targets established in the Expenditure and Investment Plan (PGI), through the integration of the PMI–PPM, PRINCE2, and ISO 21500 frameworks.The content is structured around a diagnosis of the current management of the agreement, an assessment of organizational maturity using the HumansPRO Maturity Project Framework model, a comparative analysis of the selected methodological frameworks, and the design of a corporate governance plan tailored to the interinstitutional context.The methodology adopted a mixed-methods approach with a predominantly qualitative orientation, developed through a single case study. Documentary analysis of audit reports, supervision reports, regulations, and specialized literature was conducted and complemented by the application of the HMPF model to assess the organization’s maturity.The results identified nine structural gaps related to strategic planning, governance, benefits management, risk management, monitoring and control, budget execution, process standardization, and knowledge management. The maturity assessment yielded an overall score of 1.74/5 (35%), revealing significant weaknesses in sustainability, impact, and public value creation. In response, a model was designed consisting of a multi-level governance structure, six standardized processes, seven operational instruments, and twelve performance indicators. The discussion concludes that the under-execution issues are primarily attributable to governance deficiencies rather than a lack of resources. Finally, it is concluded that implementing the proposed plan would strengthen institutional capacity, improve PGI execution, and enable the achievement of higher levels of organizational maturity, without requiring substantial legal modifications or significant investments in information systems.
