Hello all,

Above the concrete roof of the project, there are the steel structure (about 10m high) with the perforated panels for wall and grid mesh at the top. The grid mesh has about 80% perforation. there are the cat ladder provision from the concrete rooftop to the top of the grid mesh roof. My question are:
1) does the concrete roof (10m below the grid mesh and well shaded with vertical perforated panels) need to comply with the SRI requirement?
2) does the cad ladder need to comply with the SRI requirement.
Appreciate your advice.

Thanks,
Grace
