amcl details
AMCL - Details
  • Will house world’s current most sensitive microscope!
  • No Electromagnetic fields close by.
  • User wanted minimal metals in building.
  • Very low air flows – during microscope operation.
  • Design-Bid-Build method
amcl commissioning
AMCL – Commissioning
  • CX was brought in by AE too late in design process ~90%
  • Lots of engineering hold points to measure and verify rebar placement.
  • Lots of measurements to verify HVAC performance in Instrument room.
  • Reqd final measurements to verify Electromagnetic fields.

AMCL
  • Construction bids were way over budget.
    • Contractor unfamiliar with CX term. $$ to cover
    • Many other factors went into $$$ (DDC, Arch design)
  • Currently redesigning with GMP approach and Contractor on board.
  • CX in-house
  • No Hold points
  • No testing of electromagnetic fields as part of project
  • No special air flow tests.
private sector bldg commissioning
Private Sector Bldg - Commissioning
  • Developer got CX on board way too late in design.
  • Cancelled Developer CX contract after first meeting – ORNL contracted for CX.
    • ORNL has VERY limited engineering staff
    • Building ~ 150,000 nusf
  • ORNL CX doing great job!
  • CX also assisting project team with LEED documentation.

  • ORNL cancelled LEED LAP contract at ~ 60% and gave to CX.
  • Construction under way and all is going good.
mouse house commissioning
Mouse House -Commissioning
  • Design-Build – complicated HVAC system
  • CX on board late.
  • Draft of CX plan rejected.
  • CX details coming together with our guidance.

  • MASTERSPEC – new sections (have not used)
    • 01810 General Commissioning Requirements
    • 01815 HVAC Commissioning Requirements
  • Has helped to augment our Engineering staff especially during construction.
  • Proved beneficial for CX to assist with LEED.
