“…This statistical study illustrated that about 83% of the causes of damage were referred to bad execution practices starting from the eighties of the past century. Thus, there is an increasing demand for developing a better understanding of the effect of bad execution practices on the performance of concrete structures, especially on cracking in order to determine the proper method of repairing these defects [7][8][9].…”

The paper presents the effect of loading type on RC T-beam sections involving construction errors. This study involved 12 RC T-beams specimens divided into two main categories according to loading method. First category was loaded with uniformly distributed load at two-edges of slab while the second, were loaded with two-point concentrated loads at the middle length of beam specimen. The aim of this study is to evaluate, the effect of malposition of slab reinforcement, unequal configuration of slab reinforcement and change in bar diameter of slab reinforcement on the structural behavior of T-beam sections. The results indicated that malposition of slab reinforcement leads to a lower bending moment capacity of the slab. Flexural capacity of T-beams was higher than the rectangular beams where part of slab contributes to the resistance of the loads. Well-arranged distribution of reinforcement improves the ductile behavior of the slab and reduces the corresponding deflections.

“…Therefore, the widespread incidence of dimensional inconsistencies can be said to be a tolerance problem, which is not only design-related but also construction-related (Talebi et al, 2020). Baiburin (2017) for instance indicates that design errors account for only 4% of defects in construction. This aligns with the notion that dimensional inconsistency in construction elements, materials and components from nominal values or design specifications are among the most common and recurring defects in conventional construction (Talebi, 2019;Forcada et al, 2016;Jingmond and Agren, 2015).…”

PurposeCompliance with standard specifications in stairway design and construction, particularly the step geometry, is imperative for the safety and usability of stairs. The purpose of this study, was to assess the compliance of stair step geometry parameters with standard specifications in selected public buildings in Ghana. Specifically, the study investigated the prevalence of deviations in step geometry parameters from standard provisions; how significant these deviations are in comparison, and by theoretical association, the potential risk of accidents.Design/methodology/approachField measurement of the geometric parameters of a total of 1954 steps in 204 flights of stairs within 28 university buildings was undertaken using a calibrated Multi Digit Pro + digital spirit level and a tape measure following the Nose-to-Nose Method. The results were analyzed using in Microsoft Excel 2016 and Minitab 18 and interpreted based on mean values, one-sample t-test and percentages.FindingsAlthough some parameters generally complied with standard specifications, dimensional inconsistencies in risers and treads of adjacent steps were most prevalent, and significantly at margins far above standard specifications. The findings of the study show the unique limitation of the step geometry design requirements specified in the current Ghana National Building Code and the National Building Regulation, and by association, the potential risk of accidents and discomfort in the use of stairs in public buildings such as those on university campuses.Practical implicationsThe observed deviations in the dimensions of risers and treads point to a lack of strict compliance with standard specifications in the design and construction of stairs. Apart from engaging skilled artisans, and intensifying supervision in stair construction, development control authorities in Ghana need to strengthen inspection of stairs during construction to ensure and enforce compliance.Originality/valueFindings of the study provide insight into stairway design, as well as stair safety and usability in a developing world context, and allows for a more comprehensive study of stair-related accidents and discomfort associated with stairs in public buildings as a basis for the review of standards and codes in Ghana and other developing countries.

Modeling of Causes and Consequences of Human Error in Mining Processes Design: A Qualitative Study

et al. 2022

Given the significant role of mining in sustainable development and its intrinsic characteristics, the hazards and potential consequences are a great concern for the industry. A design error is one of the main reasons behind accidents and environmental disasters. This study aims to identify and categorize effective factors influencing design errors and their health, safety, and environmental consequences. The study was carried out based on the theme analysis of 12 Iranian surface miners’ opinions from 14 October to 25 December 2021. The data were collected using semi-structured interviews. The data analysis procedure was conducted based on the Strauss Model using MAXQDA2022. In the open coding section, 120 and 146 primary codes were identified regarding causes and consequences, respectively. As for the codes for causes, 26 main categories and five subcategory codes were identified, including organizational, personal, environmental, occupational, and external factors. As for the identified codes for consequences, 11 subcategories and three main categories were identified, including safety, health, and environmental effects. The findings of the study revealed that among causes, the external factor (p = 0.3703) had the weakest, and the personal factor (p = 0.003) had the strongest correlations with human error in design. In line with the opinion of the expert participants, design error had significant relationships with safety (p = 0.002), environmental (p = 0.01), and health effects (p = 0.034). The cause-consequence model introduced in this study can help many organizations, particularly surface mines, to provide a good basis for achieving sustainable safety, health management, and sustainable development.
