The essence of this research is the development of a working model in which two fundamental tools that control the quality of a finished product are brought together. In this case, the synergy is between the BIM methodology and the Lean Construction philosophy, which will be applied together to improve the quality control of the finished product of a retail construction project. Retail projects which are large investment projects, for which the owners demand high quality in the final product. The work model proposed in this study aims to solve the problem of customer dissatisfaction or dissatisfaction with the final product of a retail construction project. The disagreement on the part of the end user is mainly due to poor quality control during all stages of the project. Based on academic articles and previous studies, a procedure will be proposed in which both the Lean Construction too...

The World Health Organization (WHO) recommended laboratory tests in symptomatic individuals who meet Covid-19 case criteria as soon as possible from the onset of the disease. To evaluate the benefit of the use of laboratory tests for Covid-19 on work absenteeism, we report the case of a construction company in the city of Lima (Peru), between June 2020 and 2021. It was concluded that the use of laboratory test for suspected cases of Covid-19 had a 54% decrease in days projected absence from work and saving of 51% in the projected cost of days of absence from work in discarded cases of Covid-19. Then, the use of laboratory test for Covid-19 was useful to prevent unnecessary absenteeism.

The Rorschach test has considerable potential to contribute to the study of cognitive processes, especially the representational world and of how individuals construct meaning. The representation of self and other is currently a major topic in attachment research and in social cognition and is very relevant for clinical psychology and psychiatry because it provides a way of understanding psychopathology that goes beyond the simple listing of manifest symptoms that is so prevalent today in descriptive psychiatry. This new emphasis on mental representation should enable us to extend our understanding of psychopathology and to discover new ways of systematically assessing a wide range of psychological disturbances.

This study evaluates how Information Technology (IT) creates value in the performance of physical infrastructure (PI) projects. The research model is based on the concept of the Business Value of Information Technology (BVIT) and relates the integration of IT resources with the development of IT capabilities to promote the performance of PI projects. The model is evaluated empirically from first-hand data collected from surveys in public and private organizations whose core is the development of PI projects in Colombia. The empirical test indicates there is a strong relationship between IT and PI performance when the effects of IT resources and capabilities are mediated through the underlying mechanisms composed by IT support for competitive strategies and core competencies. The strong correlation between predictor constructs and PI project performance is confirmed upon calculating the t...
