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

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

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

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

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

11. Analysis 1 Disadvantages of using a CCIP:
Additional administrative duties

12. Analysis 1 Disadvantages of using a CCIP:
Additional administrative duties
Increased responsibility to ensure jobsite safety

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

23. 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

24. 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

25. 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

26. 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

27. 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

28. 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

29. Water-Mist vs. Traditional Sprinkler Systems

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

31. Analysis 2 Initial Installation Costs Maintenance Costs
Pre-action: $810,500
Water-mist: $912,000
Maintenance Costs
Pre-action: $ per year
Water-mist: $ per year

32. 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

33. Flexible Building Design
Analysis 3
Flexible Building Design

34. Analysis 3 Flexibility in building design needed due to:
Rapid Population Growth
Emerging Technologies

35. 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

36. 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

37. Analysis 3 Advantages: Simplified Formwork Added plenum space
Height Reduction
Unrestricted placing of partitions

38. Analysis 3 Cost Analysis Existing Structure: $11,121,278
Flat Slab System: $8,221,602

39. Analysis 3 Schedule Analysis Existing System: 26 weeks
Flat Slab System: 23 weeks

40. Analysis 3 Panel Partition Walls Advantages Quick and easy assembly
Reusable
Can be taken down and reassembled in other locations
Dust free renovations

41. Analysis 3 Cost Analysis Existing Walls: $593,000
Panel System: $566,250

42. 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

43. 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
