Construction Workers’ Perceptions of Safety Practices: A Case Study in Mexico

Organizational characteristics and worker perceptions are among the main factors affecting the safety climate in construction sites. Although some perceptions of the workers may seem absurd to others, these components are part of their reality. Worker behavior is an extremely important factor in workplace safety as many accidents are often caused by insecure actions, in which combinations of human behavior are the consequence of such perceptions. The aim of this study was to explore workers’ perceptions of safety practices in their habitual work environment, a building site in Mexico. Worker perceptions of safety practices were captured using an instrument in which the following dimensions were taken into consideration: Education and training, Work motivation, Family and social integration, Work place integration, Safety awareness integration, and Accidents. The conclusion was that the workers have received very little education and possess a limited culture of safety awareness, which has led them to perceive that their lack of precaution is the main cause of accidents.

An Intelligent Optimization Method of Reinforcing Bar Cutting for Construction Site

To meet the requirements of specifications,intelligent optimization of steel bar blanking can improve resource utilization and promote the intelligent development of sustainable construction.As one of the most important building materials in construction engineering,reinforcing bars(rebar)account for more than 30%of the cost in civil engineering.A significant amount of cutting waste is generated during the construction phase.Excessive cutting waste increases construction costs and generates a considerable amount of CO_(2)emission.This study aimed to develop an optimization algorithm for steel bar blanking that can be used in the intelligent optimization of steel bar engineering to realize sustainable construction.In the proposed algorithm,the integer linear programming algorithm was applied to solve the problem.It was combined with the statistical method,a greedy strategy was introduced,and a method for determining the dynamic critical threshold was developed to ensure the accuracy of large-scale data calculation.The proposed algorithm was verified through a case study;the results confirmed that the rebar loss rate of the proposed method was reduced by 9.124%compared with that of traditional distributed processing of steel bars,reducing CO_(2)emissions and saving construction costs.As the scale of a project increases,the calculation quality of the optimization algorithmfor steel bar blanking proposed also increases,while maintaining high calculation efficiency.When the results of this study are applied in practice,they can be used as a sustainable foundation for building informatization and intelligent development.
