Analysis 2 Water-Mist Fire Suppression System
Analysis 2 Water-Mist Background • Originally developed for protection of lumber drying kilns and ships • Gained popularity when Halon was deemed environmentally unsafe • Used today to protect gas turbines, machine rooms, and ships • Also used in computer rooms and laboratories • Recently used in the National Gallery of Art in Washington, DC
Analysis 2 How It Works • Highly pressurized nozzles release water droplets of varying size • Mist surrounds the fire and vaporizes, absorbing energy and removing heat from the source • Mist expands greatly, forcing oxygen away from the flame
Analysis 2 • Goal: To determine whether or not it would be advantageous to implement a water-mist system in the computer/data rooms and laboratories in the Memorial Hospital Miramar
Analysis 2 • Existing System: Traditional pre-action fire suppression system • Disadvantages • Large amount of water used to suppress fire • Larger piping needed to hold water • Little smoke control
Analysis 2 • Proposed System: HI-FOG water-mist system with smoke scrubbing • Incorporates sub-floor piping and ceiling piping • Sub-floor piping discharges mist in opposite directions causing the smoke to be sucked in and scrubbed • Ceiling mounted pipes discharge mist directly into room
Analysis 2 • HI-FOG System Advantages • Uses only 10-20% of water used in pre-action system • Smaller stainless steel piping • Smoke scrubbing element • Radiant heat blocking
Analysis 2 Water-Mist vs. Traditional Sprinkler Systems
Analysis 2 • Initial Installation Costs • Pre-action: $810,500 • Water-mist: $912,000
Initial Installation Costs Pre-action: $810,500 Water-mist: $912,000 Maintenance Costs Pre-action: $500-1000 per year Water-mist: $1000-2000 per year Analysis 2
Analysis 2 Conclusion: Due to higher first costs and higher maintenance costs of the water-mist system, the existing pre-action system should be used
Analysis 3 Flexible Building Design
Analysis 3 • Flexibility in building design needed due to: • Rapid Population Growth • Emerging Technologies
Analysis 3 • Goal: To increase the flexibility of the Memorial Hospital Miramar to enable the building to efficiently adapt to the changing needs of the user
Analysis 3 • Structural Redesign • Existing System: CIP Beams and Pre-cast Soffits • Proposed: Flat Slab System with Shear Walls • 10” slabs with 3” drop panels at columns • 8” shear walls around stairs and elevators
Analysis 3 • Advantages: • Simplified Formwork • Added plenum space • Height Reduction • Unrestricted placing of partitions
Analysis 3 Cost Analysis • Existing Structure: $11,121,278 • Flat Slab System: $8,221,602
Analysis 3 Schedule Analysis • Existing System: 26 weeks • Flat Slab System: 23 weeks
Analysis 3 • Panel Partition Walls • Advantages • Quick and easy assembly • Reusable • Can be taken down and reassembled in other locations • Dust free renovations
Analysis 3 Cost Analysis • Existing Walls: $593,000 • Panel System: $566,250
Analysis 3 • Panel Walls can cut erection time by approximately 13 days • Walls can be taken down and reassembled nearly 2x as fast as the regular wall system
Analysis 3 Conclusion Both the flat slab system and panel partition walls can not only save time and money on the project, but also give the building more flexibility to adapt to changing user needs
