In recent decades, accelerated urban growth in Arequipa has led to the loss of more than 40% of riparian vegetation and increased ecological fragmentation in the Chili River valley. This transformation has degraded water quality and limited equitable access to green and public spaces. Therefore, this research aims to design a Green Corridor along the Chili River as an ecosystem-based strategy to enhance social connectivity and ecological resilience in Arequipa, Peru. The methodology combined an extensive literature review, a comparative analysis of international case studies, and a territorial diagnosis supported by geospatial and climatic data. The process is supported by digital tools such as Google Earth Pro 2025, AutoCAD 2024, SketchUp Pro 2023, and solar simulations with Ladybug-Grasshopper, complemented by data from SENAMHI, SINIA, and the Solar Atlas of Peru. The results propose a resilient green corridor integrating passive and active sustainability strategies, including 40 photovoltaic panels, 44 solar luminaires, biodigesters producing between 90 and 150 kWh per month, and phytotechnologies capable of absorbing 75,225 kg of CO₂ annually, based on WHO conversion factors adapted to high-altitude conditions. The proposal employs eco-efficient materials such as reforested eucalyptus wood and volcanic sillar, creating recreational and productive spaces that promote social cohesion and circular economy. In conclusion, this study demonstrates the potential of ecosystem-based design to regenerate arid urban riverbanks, harmonizing environmental sustainability, social inclusion, and cultural identity. Thus, the Chili River corridor is consolidated as a replicable model of green-blue infrastructure for Andean cities, aligned with Sustainable Development Goals 6, 7, 11, 12, 13, and 15.

This study introduces and evaluates an innovative methodology for assessing constructability in the maintenance of university buildings, aiming to improve the quality of academic infrastructure. The proposed approach is based on four key criteria: functionality, usage, investment, and curricular planning. These criteria are derived from the principles established by the Chilean Construction Industry Council (CCI Chile, 2024) and were applied in a case study at Ricardo Palma University. A quasi-experimental research design was implemented in two physical spaces within the Faculty of Architecture and Urbanism, one of which underwent a maintenance intervention while the other remained unaltered. Data was collected through expert-validated instruments, administered to senior students and technical staff before and after the intervention. The results revealed significant improvements, with satisfaction levels increasing from 44% to 56% among students and a 10% rise in positive technical evaluations (p < 0.005) which reflected an improvement in the perceived quality of the academic environment, especially in areas related to maintenance planning, execution, control, safety, and user comfort. This study concludes that integrating constructability criteria into the maintenance phase can optimize infrastructure management, enhancing sustainability, operational efficiency, and user satisfaction. The developed methodology offers a practical and replicable tool for other academic units and universities, supporting continuous improvement and promoting evidence-based decision-making in the management of educational facilities.

This study examines the link between post-construction constructability and perceived service quality in a 15-building campus at Ricardo Palma University (Lima, Peru). The research combined technical assessments, user surveys, and document analysis. Constructability was operationalized across six dimensions: compliance with quality requirements, adherence to design, valuation, execution time, social impact, and environmental impact. Service quality was measured through user satisfaction surveys. The instruments were validated through expert judgment, while data were analyzed using descriptive statistics, Spearman’s correlations, and non-parametric bootstrap procedures to address the limitations of a small sample size (N = 15). Results indicate positive associations between constructability efficiency and service quality, highlighting that projects with higher constructability scores achieved better user satisfaction levels. The findings provide a replicable framework for evaluating university facilities and offer practical implications for facility management and institutional sustainability.
