The installation of complex and ornate ceilings has become the norm rather than the exception in many contemporary construction projects. Special situations involving spaces above ceilings, open grid ceilings, drop out ceilings, ceiling clouds and stepped ceilings will be reviewed. Architectural ceiling designs have continued to evolve beyond the limitations for cloud ceilings. The special ceiling situations included in the sub-sections of 8.15 will be reviewed. Sprinkler protection requirements and compliance options will be discussed for these unique and challenging ceiling configurations.
