Item

Scope

1. Material Specifications

2. Laboratory Tested Fire Resistance Design

Review UL fire resistive design for each rated beam, column, or assembly.

3. Schedule of Thickness

Review approved thickness schedule.

4. Surface Preparation

Inspect surface preparation of steel prior to application of fireproofing

5. Application

Inspect application of fireproofing.

6. Curing and Ambient Condition

Verify ambient air temperature and ventilation is suitable for application and curing of fireproofing.

7. Thickness

Test thickness of fireproofing (ASTM E605). Perform a set of thickness measurements for every 1,000 SF of floor and roof assemblies and on not less than 25% of rated beams and columns.

8. Density

Test the density of fireproofing material (ASTM E605).

9. Bond Strength

Test the cohesive/adhesive bond strength of fireproofing ASTM E736). Perform not less than one test for each 10,000 SF.
