Contract Drawing
Subject
RSS Wall Soil Reinforcement Length
Enquiry
In drawing 194A NBL Retaining Wall, Note #2 states "Minimum RSS wall reinforcing strip length required against global instability: North Abutment - Stepped Wall: 2.5H" On drawing 179A the walls are shown as back to back. This cannot be achieved for design or construction as the soil reinforcement will equate to approximately 24m long while the distance between walls is approximately 15m. Please clarify.

Response
The height of the wall should be taken as the height from the final ground surface at base of wall to the top of the wall. Where the distance between the walls is less than the calculated minimum RSS wall reinforcing strip length, then the strip length should be equal to the distance between the walls.
