Agenda Analysis 1 – Insurance Policies Analysis 2 – Water-Mist Fire Suppression System Analysis 3 – Flexible Building Design

Analysis 1 Insurance Policies in the Construction Industry: Contractor Controlled Insurance Policies (CCIP)

Analysis 1 Advantages of using a CCIP: Broader coverage and higher limits for contractors

Analysis 1 Advantages of using a CCIP: Broader coverage and higher limits for contractors Potential cost savings

Analysis 1 Advantages of using a CCIP: Broader coverage and higher limits for contractors Potential cost savings More comprehensive safety and loss control programs

Analysis 1 Disadvantages of using a CCIP: Additional administrative duties

Water-Mist Fire Suppression System Analysis 2 Water-Mist Fire Suppression System

Water-Mist Background 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

Water-Mist vs. Traditional Sprinkler Systems Analysis 2 Water-Mist vs. Traditional Sprinkler Systems Property Sprinkler Water-Mist Extinguishing No Yes Gas Cooling Radiant Heat Blocking Smoke Scrubbing Safe for People Safe for Equipment

Analysis 2 Initial Installation Costs Pre-action: $810,500 Water-mist: $912,000

Analysis 2 Initial Installation Costs Maintenance 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 Conclusion: Due to higher first costs and higher maintenance costs of the water-mist system, the existing pre-action system should be used

Flexible Building Design 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
