Proposal of a mathematical model to calculate the performance of work command in block masonry. case: Cuenca city, Cañaribamba Parish

Abstract

Introduction.  The placement of block masonry emerges as a critical phase in the construction process, where efficiency and accuracy directly influence the duration and quality of the project. This activity, although seemingly simple, carries an inherent complexity that often results in significant delays in the execution of the work. The need to understand and address the factors contributing to these delays is evident, as their impact is not only reflected in terms of schedule and budget, but also in client satisfaction. Objective.  To propose a mathematical model to calculate the labor performance in the placement of masonry with blocks in Cañaribamba Parish, Cuenca, Ecuador. Methodology.  The methodological design adopted follows a relational and descriptive orientation, involving the collection of data from nine construction sites by means of an observation sheet that covers both external and internal factors. Using these data, a linear regression analysis was carried out using a statistical program. Results.  The results highlight that, individually, none of the factors analyzed significantly influences job performance; however, the combination of these factors allows predicting performance with an accuracy of 93.3%. Conclusion.  It is concluded that linear regression emerges as a robust tool to anticipate the performance of work crews in the Cañaribamba Parish, considering the complexity of both internal and external factors in the works.
