Unformatted text preview: involve longterm education and institutional changes. Barrier: Risk of Additional Designer Liability
Barrier: Barrier: Designers’ concerns about additional undeserved liability for worker safety. Potential solutions: • Clearly communicate we are NOT suggesting designers should be held responsible for construction accidents.
• Develop revised model contract language to facilitate DfCS without inappropriately shifting liability onto designers. Barrier: Increased Designer Costs
Associated with DfCS
Associated Barrier: DfCS processes will increase both direct and overhead costs for designers. Potential solution: • Educate owners that total project costs and total project life cycle costs will decrease Barrier: Designers' Lack of Safety
Expertise Barrier: Few design professionals possess sufficient expertise in construction safety.
• Add safety to design professionals’ curricula.
• Develop and promote 10hour and 30hour OSHA courses for design professionals. DfCS Examples: Prefabrication Concrete Wall Panels
Concrete Segmented Bridge
Steel stairs DfCS Examples: Anchorage Points DfCS Example: Residential Roofs
Residential DfCS Examples: Roofs
Skylights Upper story windows and roof parapets DfCS Examples: Steel Design National Institute of Steel Detailing and Steel Erectors Association of America. Detailing Guide for the Enhancement of Erection Safety. 2001 Avoid hanging connections; design to bear on columns instead using safety seats
Require holes in columns for tie lines 21” and 42” above each floor slab
Specify shop welded connections instead of bolts or field welds to avoid dangerous positions during erection
Consider approximate dimensions of connection tools to prevent pinches or awkward assemblies Example of the Need for DfCS
Example Worker electrocuted when his drill rig got too close to overhead power lines.
Design engineer specified groundwater monitoring wells were to be dug directly under power lines.
Engineer could have specified wells be dug away from power lines and/or better informed the employer of hazard posed by wells’ proximity to powerlines through the plans, specifications, and bid documents. Other DfCS Design Examples
Other Design underground utilities to be placed using trenchless technology1
Specify primers, sealers and other coatings that do not emit noxious fumes or contain carcinogenic products2
