Performing Arts Theater Smoke Control System Analysis
Performance Based Fire Protection Engineering, PLLC utilized Fire Dynamics Simulator (FDS) to examine the effects that severe case fire scenarios would be expected to have on a theater space, specifically in regard to smoke movement and tenability conditions. In an ASET/RSET approach, a timed-based egress analysis was also performed and coupled with the fire modeling results, to demonstrate that by certain time steps occupants would not be expected to be in specific locations of a space which may be experiencing undesired tenability conditions. The goal of this analysis was to determine required smoke control system components and capacities, to serve as smoke protected seating.
High-Rise Smoke Control System Analysis
Performance Based Fire Protection Engineering, PLLC addressed requirements regarding stairwell pressurization, elevator hoistway pressurization, guestroom corridor smoke control, and public exit access smoke control system for a high-rise hotel who still maintains corridor protection provisions. CONTAM, a building airflow and contaminant dispersal model, was utilized in order to dial in mechanical capacities and configurations of the systems. This analysis resulted in the client being able to exclude elevator lobbies through pressurization of the elevator shafts and utilizing an Exterior Vent (EV) system, to eliminate competition against the other smoke control systems.
TRANSFORMER FIRE HAZARD ANALYSIS
Performance Based Fire Protection Engineering, PLLC reviewed hazards of oil-insulated transformers as they relate to compliance with the performance requirements of NEC Article 450.27. Through the use of Fire Dynamics Simulator (FDS), transformer fires were evaluated against various conditions and exposures to an adjacent Type V/IA podium apartment building. Findings from this analysis allowed for a decrease in horizontal spacing of the transformer pads, provided that a deluge exposure protection sprinkler system was included to protect lower portions of the exterior walls.
Manufacturing Facility Smoke & Heat Vent Analysis
Performance Based Fire Protection Engineering, PLLC provided a smoke and heat vent analysis on a fully sprinkelred 90,000 sq. ft. Factory Industrial F-1 Moderate-hazard Occupancy; the AHJ for the jurisdiction requires smoke and heat venting for this type of occupancy. Code requirements for such a system, as well as required free areas of natural ventilation methods and capacity (CFM) for mechanical exhaust methods were provided to the client.
Office Building Property Condition Assessment
Performance Based Fire Protection Engineering, PLLC surveyed an existing high-rise office building to review the fire protection features provided for the building, inclusive of the fire protection systems (sprinkler and standpipe), fire alarm system and passive fire protection features. The general condition of these systems and potential fire protection code deficiencies were observed. A report containing a description of the building systems as they apply to fire protection, and recommended actions for noted deficiencies was provided to the client. In some cases the code of record at the time of construction, the 1986 Standard Building Code, had to be compared to more common codes.
