REF: S103 and Elevator Submittal (Otis)
On drawing S103 the elevator W 8x24 hoist beam is shown running North and South. The elevator submittal shows the elevator hoist beam running East and West. After speaking with Tim Thompson (Otis Elevator) it was confirmed that the hoist beam must run East and West to set the elevator side rails. Please provide new hoist beam size and any additional supporting details/embeds.
Suggestion
Answer Accept Suggestion
JVA Response:
Changing beam size is not necessary, a W8x24 will still work. The connections at bearing ends remain the same. Coordinate new dimensions with steel fabricator and/or Otis and also with the now perpendicular 10K1 (not 8K1) joist at roof.
