Urban Thrie-Beam Crash Barrier

I need a complete design package for a thrie-beam crash barrier that will be installed along an urban road. My overriding priority is safety performance, so every element—from post spacing to connection details—must be optimized to absorb impact energy and keep vehicles within the carriageway.

Composite materials are my preferred choice because of their corrosion resistance and potential for weight reduction; feel free to recommend the exact composite lay-ups or hybrid configurations that meet current crash-test standards while remaining practical for roadside maintenance crews.

Please base your calculations and drawings on the governing urban-road guidelines in force (e.g., EN 1317 or the equivalent for my region) and clearly show compliance. I will need:
• Detailed layout drawings (plan, elevation, typical sections)
• Structural calculations with impact simulations or analytical proof of containment levels
• A concise installation manual that a contractor can follow on-site
• A bill of materials listing all components and any proprietary fittings

Final files should be delivered in both editable formats (DWG/Excel or similar) and PDF for easy review. I will consider the work complete once the design passes a safety peer review and all documentation is delivered clean and error-free.
