Dead Load1111dsfasd
Dead loads are determined from the actual weights of materials and fixed service equipment. Typical assumed weights for assemblies are as follows:
| Assembly Type |
Dead Load (PSF) |
| Metal Panels |

| Curtain Walls |
10 |
| Stone or Brick Veneer |
40 |
| Adhered Stone or Brick |

Equipment Loads
- Assumed loads for known equipment are shown on the structural drawings.
Any change in type, size, location, or weight of equipment must be reported to the Engineer of Record (EOR) for verification of the supporting members before shop drawing submission.
- Equipment loads include the weight of concrete pads or curbs, if applicable.
- For equipment not shown on the structural drawings, if the unit weight divided by its bearing area exceeds the specified live load for that location, the contractor must notify the EOR prior to shop drawing submission.
