•Material conditions:
•Steel: rust
•Concrete: cracking and rust
•Wood: sturdy, but not ideal
•Design decisions:
•Steps: Steel frame filled with concrete.
•Deck: greater than CTADG standard (over 2 meters)
•Goal: to evaluate these materials and design decisions and to suggest improvements.
Maintenance Needed
Cracking on concrete abutment
Inspect the steel staircase frame
Install 2nd bike ramp?
Water collection on abutments
Replace baluster
1st improvement: Metallic Deck
Replace the wooden deck with metal
Wood needs replacement often
Metal lasts 3 times longer
Weight is same
Production cost is slightly higher
Improves maintainability

2nd Improvement: Rails Add the extra handrail in the middle. Stairs are especially slippery (due to
metal frame) Bridge is wider than 2000 mm.
Improves the heavy traffic. Safer (less falling down the stairs) Improves user experience
I told you about the stairs bro.
