Overview
The revisions to the S-102 Roof Plan primarily focus on structural modifications to the mechanical unit support framing, updates to various roof elevations, and the addition of specific structural lintel requirements for CMU walls. Former W10x54 beams and dunnage framing callouts have been replaced with W8x18 lintels. High Roof elevations adjusted by approximately 1 inch.
Drivers
  • Mechanical RTU framing revised from W8X28 beams to W8x18 lintels near grid lines B-C / 3-5.
  • New structural lintel specifications added for CMU walls near grid line G/1.
  • Roof elevation adjustments for High Roof high point and low point.
Next steps
  • Confirm RTU loading with mechanical contractor for revised W8x18 lintel configuration.
  • Coordinate CMU lintel installation with masonry contractor (HSS12x10x1/2 and W8x18).
  • Update steel shop drawings with revised framing members.
