Hello, Can you please respond to the following questions? These are all RFIs from the interested contractors.
It appears that the stair to the new dunnage platform is to be reused per the drawings. Please confirm or advise if a new stair is needed. If stairs and platform meet the required height and are code compliant, then they can be reused. If not new stairs and deck will be required. The existing stair and platform are still in good shape. Reuse them to save cost if they meet codes.
