Who is responsible for determining hourly ratings and the correct U.L. design and ultimately the correct thickness of fireproofing?
Model building codes and numerous state laws mandate that only the “Design Professional” (a registered architect or professional engineer) can make these determinations. W. R. Grace & Co.-Conn. can only recommend the appropriate design and thicknesses. All of our recommendations must be reviewed and approved by the design professional for the particular project through the contractor’s normal submittal process and this information must subsequently be reviewed and approved by the building code official having jurisdiction for the specific project.
