Conclusion

  • Options for Interstitial Construction

    • Catwalk - cheapest, least advantageous

    • Suspended - frequently used but introduces vibration and coordination problems

    • Full Composite Floor - expensive, most advantageous

  • Redesign

    • RAM Steel redesign for cGMP area only

      • LRFD design

      • 40 psf live load (ASCE 7-98) – similar to maintenance catwalk

      • 3 ¼” light weight concrete slab on 2” deck

    • Seismic and wind loads change

  • Structural Conclusions

    • Main cost increase

    • Room for cost savings and value engineering in floor selection and frame layout

    • Design issues are minimal if interstitial design is selected initially

Conclusion

  • Additional Building Loads

    • HAP Analysis

      • 5’ existing plenum compared to 9’ interstitial space

      • Equipment loading the same in both scenarios

      • Lighting and occupancy allowance in interstitial

    • Analysis Results

      • Difference of 5.2 tons between scenarios – makes up only 1% increase in total building load

  • Mechanical Conclusions

    • Not a significant increase in building load

    • Efficiency of design, modularity and other advantages far outweigh any load increases

Conclusion

  • Lighting/Electrical

    • Similar to other maintenance areas

    • Interstitial design has a minimal direct effect on lighting and electrical systems

  • Fire Protection

    • Research shows no problems with fire codes

    • Surveys show a need for additional fire dampers due to penetrations

  • Acoustics

    • Depends on floor system selected

    • Isolation of MEP systems may reduce noise
