Can Design Improve Construction Safety?: Assessing the Impact of a Collaborative Safety-in-Design Process

Abstract

This paper analyzes the impact of a large-scale safety-in-design initiative during the design and construction of a semiconductor manufacturing facility in the Pacific Northwest of the United States. Drawing on multiple data sources including individual interviews, group interviews, construction documentation, and an expert panel involved in the initiative, the writers identify 26 potential design changes on the project and assess the importance of timing, trade contractor involvement, and the type of design change in determining whether a proposed design change was ultimately integrated into the final construction plans. The writers further consider whether adopted design changes would have occurred in the absence of the safety-in-design initiative and whether the accepted design changes ultimately impacted construction site safety on the project. This analysis of a full-scale safety-in-design initiative provides important insights into how injury prevention efforts in the construction industry can begin upstream by involving designers, engineers, and trade contractors in preconstruction processes.

Estimating the Influence of Improper Workplace Environment on Human Error: Posterior Predictive Analysis

“…is result indicates the necessity of the incorporation of "resilience" into the workplace environment. For instance, Weinstein et al [43] collected and categorized many workplace environment recommendations from industry experience in which a specific fixed position of an anchor point for a lifeline was stipulated to ensure that protection is available when needed.…”

The Role of Ergonomics for Construction Industry Safety and Health Improvements

“…Therefore, preventive measures by considering any safety problem and/or risk should be offered from a planning stage or phase. This precautionary approach may potentially reduce majority accidents in the construction industries [18,19].…”

Using BIM as a Tool to Teach Construction Safety

“…In the area of construction safety, the applications and researches on BIM has also been widely recognized, focusing on the planning and design phases to improve safety during construction by connecting construction safety issues to construction planning [4], [5], and [6]. BIM-based modelling and 4D simulation allow design engineers to exercise various design alternatives that best address safety issues, as well as determining whether any proposed design change is integrated into final construction plans.…”
