2. What is Prevention through Design (PtD)? The process of addressing construction site safety and health in a project’s design. The process of addressing construction site safety and health in a project’s design. Construction site safety as a design criterionConstruction site safety as a design criterion Focus on the design of the permanent facilityFocus on the design of the permanent facility “Safety constructability”“Safety constructability” Designing for construction safety (DfCS)Designing for construction safety (DfCS) PtD is not: PtD is not: Specifying means and methods of constructionSpecifying means and methods of construction Control of, or responsibility for, safety on the construction siteControl of, or responsibility for, safety on the construction site

3. PtD in the U.S. Interest in PtD is growing, but PtD is currently not part of standard practice Interest in PtD is growing, but PtD is currently not part of standard practice Barriers: Barriers: OSHA’s placement of safety responsibilityOSHA’s placement of safety responsibility Designer education and trainingDesigner education and training Lack of design tools, guidelines, proceduresLack of design tools, guidelines, procedures Designer’s limited role on the project teamDesigner’s limited role on the project team Designer’s traditional viewpoint on construction worker safetyDesigner’s traditional viewpoint on construction worker safety Lack of understanding of the associated liabilityLack of understanding of the associated liability Absence of legislative mandateAbsence of legislative mandate

Research Needs Design-related causality of occupational injuries and illnesses Design-related causality of occupational injuries and illnesses How to assess design-related causalityHow to assess design-related causality Connection between specific design features and worker safety and healthConnection between specific design features and worker safety and health Needed to conduct the research:Needed to conduct the research: Better surveillance data Better surveillance data Consider both injury frequency and severity Consider both injury frequency and severity

11. Accidents Linked to Design 1,2 22% of 226 injuries that occurred from 2000-2002 in Oregon, WA, and CA 22% of 226 injuries that occurred from 2000-2002 in Oregon, WA, and CA 42% of 224 fatalities in the U.S. between 1990-2003 42% of 224 fatalities in the U.S. between 1990-2003 In Europe, a 1991 study concluded that 60% of fatal accidents resulted in part from decisions made before sitework began. In Europe, a 1991 study concluded that 60% of fatal accidents resulted in part from decisions made before sitework began. 1 Behm, “Linking Construction Fatalities to the Design for Construction Safety Concept”, 2005 2 European Foundation for the Improvement of Living and Working Conditions
