Puget Sound Blood Center Phase II

Project:

  • 60,000 ft2 Laboratory & Office Space
  • Existing Warehouse Conversion to Laboratory & Office

Site Location:

  • Renton, WA

Team:

  • Owner - Puget Sound Blood Center
  • Architect - Mithun
  • Engineer - SIDER + BEYERS Associates, Inc.
  • GC - BNBuilders, Inc.
  • HVAC - PSF Mechanical, Inc.

HVAC Systems:

  • Chilled water using rooftop air-cooled scroll compressor chillers (N+1 redundancy), 240 tons total
  • Indoor custom air handler, 68,000 CFM VAV with air-side economizer
  • Specialty exhaust systems
  • DDC EMCS
  • Full build-out of existing warehouse shell
  • Specialty exhaust systems

Unique Design Challenges:

  • Ultra fast track project schedule/coordination
  • Extreme logistical challenges:
    • Quick cycle equipment procurement
    • Construction initiated prior to design completion
    • GC initiated structural solution to mechanical/electrical support requirements (interstitial structural steel support grid beneath 30’ roof)
  • PSF engaged as coordination control point for GC, initiated BIM process
  • Overlapping construction/design process - PSF utilized temporary supports to allow pre-installation of major duct runs and mechanical components while interstitial structure was designed, procured and erected

Energy Saving Strategies:

  • Air-side economizers
  • VAV air distribution throughout office and laboratory areas
  • DDC EMCS controls
  • Variable frequency drives
  • Variable flow primary chilled water system
  • Plug supply and relief fans
