Artificial Bee Colony Algorithm to Optimize the Safety Distance of Workers in Construction Projects

This paper presents the results of a simulation model regarding the productivity and safety working space for construction workers through the floors of a building using swarm intelligence (SI), a field of artificial intelligence (AI), and specifically using artificial bee colony (ABC) optimization. After designing the algorithm used to build the simulation model, the simulation was used in an actual building project by comparing the travel times of workers conventionally transporting material with another group working on routes optimized by the algorithm. Thus, the proposed algorithm provides routes combining shorter travel times and correct distances between workers when transporting materials in a construction site, handling the interference between crews. After validating the algorithm on-site, no statistically significant differences were found between the travel times of workers and the times delivered by the algorithm. Additionally, the travel times using the routes obtained through the algorithm were significantly lower than those made by workers who moved freely without a predefined route. In summary, the algorithm proposed may help construction practitioners maintain safe movements that respond to hazard contexts imposed by any restriction that demands a safety distance.

Labor Inclusion in the Construction Sector: Evidence from Mexico

2023 , Tovar-García, Edgar Demetrio , Ornelas-Barajas, Luis Alfonso , Moreno Abril, Francisco

This study aims to present empirical evidence demonstrating the receptiveness of construction professionals and individuals with spinal cord injuries to participate in the construction sector, challenging the prevalent belief that spinal cord injury precludes labor inclusion. Accordingly, in August 2021, this study conducted two surveys to collect data from distinct groups: builders and individuals with spinal cord injuries. The builder survey involved a representative sample of 52 respondents, drawn from a population of 322 members of the Mexican Chamber of the Construction Industry,Jalisco delegation. Simultaneously, 44 individuals with spinal cord injuries participated in the survey, sourced from a pool of 455 members affiliated with Don Bosco sobre Ruedas and Vida Independiente. The survey process facilitated a comprehensive diagnosis, identifying potential areas for enhanced inclusion within the construction sector. The empirical findings challenge conventional wisdom, indicating that a spinal cord injury does not act as a barrier to labor inclusion within the construction sector. On the contrary, the study emphasizes that having employees with disabilities can exert a positive impact on company dynamics. Moreover, the research identifies specific activities where individuals with spinal cord injuries exhibit a higher potential for inclusion, thereby redefining traditional expectations. Therefore, this study contributes to the originality of the existing discourse by providing concrete empirical evidence that counters widespread assumptions about the limitations faced by individuals with spinal cord injuries within the construction industry

Towards a Model That Sees Human Resources as a Key Element for Competitiveness in Construction Management

2023 , Romo Gamboa, Rubén , Orozco, Francisco , Eric Forcael , Moreno Abril, Francisco

The construction industry is continuously affected by external and internal agents that modify and define its competitiveness. Changing markets, currency fluctuations, and tremendous competition have made the issue of competitiveness increasingly important. The literature highlights factors that determine the competitiveness of construction firms, including easy-to-measure elements, such as financial, sales, return on investment, etc., while other elements are not as easily measurable, such as customer satisfaction, employee satisfaction, loyalty, and leadership, among many others. Within these factors, Human Resources (HR) has occupied a central place in the last decade, due to the enormous impact that labor has on project execution. This research mainly focuses on the study of HR and its components to reach a deeper understanding of the impact that HR has on the competitiveness of construction companies. After defining the most relevant variables, an interrelationships model was proposed with the Partial Least Square (PLS) technique. These HR variables impact the competitiveness variables: cost, utility, time, quality, Staff retention, and Health & Safety. The PSL analyses met the evaluation criteria using the structural model, confirming its viability. It was found that there are three important variables related to competitiveness: (i) leadership, (ii) innovation, and (iii) competitiveness.
