SECTION 12 - SPRAY-APPLIED FIRE-RESISTIVE MATERIALS
OBJECTIVE
The purpose of spray-applied fire-resistive materials observation is to verify that the application of material is in accordance with the project specifications, applicable codes, and manufacturer’s recommendations.
This objective can best be achieved by experienced special inspectors who diligently perform the duties listed below while under direct supervision of the materials engineering laboratory.
OBSERVATION DUTIES
A. Documents
- Review the approved plans, specifications, and manufacturer’s recommendations.
- Review applicable sections of referenced codes and standards.
B. Observation Procedures
- Verify substrate condition for cleanliness prior to application.
- Verify application in accordance with code and specifications.
C. Testing and Sampling Duties
- Measure thickness of spray-applied fire-resistive material in accordance with specifications and Uniform Building Code Standard 7-6.
- Remove and deliver samples to materials engineering laboratory for unit weight tests.
- Reinspect areas repaired due to insufficient thickness or damage by sampling, tenant improvements, panel placement, rain, etc.
D. Reports
- Submit written progress reports describing the tests and observations made and showing the action taken to correct nonconforming work. Itemize any changes authorized by architect/engineer. Report all uncorrected deviations from plans or specifications.
