SOME PROBLEMS & SOLUTIONS Problem: Wood joists and wood sub-floor required a 2 hour rating. The heat ducts, wiring and plumbing were in place as was the T-Bar ceiling. The cost to remove and re-install the ceiling tile system, ducting, wiring and plumbing to accommodate two layers of gypsum would have cost in the range of $150,000 Solution: Approved by the City of San Francisco. The coating was applied to all wood ceiling joists and sub-floor areas to provide the required 2 hour rating. A coating of Ff88, in matching color was applied to the ceiling to meet the fire rating required by the City. The work was completed in four working days and at a greatly reduced cost and less disruption. Problem: Non-fire rated (OSB) panels and 2X6 wall studs where used to construct exterior building shear walls at two structures at Pike Street. The panels did not meet the fire rating requirements as required by the City of Seattle. The extensive nailing of the panels to the stud walls, would have required re-framing four stories of exterior walls at both buildings. Solution: Based on testing on OSB board and wood timbers, the City of Seattle approved the use of the coating to coat the exterior OSB panels and exterior wall studs to meet the required fire rating thus preventing costly delays in construction and the need to rebuild all four stories of exterior walls. The cost savings for each building with the use of the coating was in the hundreds of thousands of dollars. Problem: The building was converted to condominiums above the first floor. The ceiling in the first floor had embossed tin ceilings requiring a 1 hour rating. To comply would have required removal of the ceiling, application of 2 layers of gypsum board and re-installation of the ceiling. The first floor area was extensive and occupied by a fabric store that was opened daily. The cost of demolition and reconstruction, including potential damage to the existing ceilingtiles, was extensive and would have required shutting down the store for a minimum of 4 weeks. Solution: Based on the coatings testing on embossed tin ceilings, we were approved and used to coat the embossed tin ceiling to provide the necessary 1 hour rating at a 60% reduction in cost. The labor was performed at night and completed in 7 work days with no disruption to the owner of the fabric store.
