In the hand-off to warranty, No complaints does not mean the system is optimized.

This approach will find system inefficiency where others will find the job working…

• Define the use of automated Cx in project specifications

• Deep coordination needed with controls vendors

• Automated Cx exposes the “copy/paste” nature of controls programming - just “making it work” is not possible with this model

• The process needs to be commissioned…

• Demonstrated potential for future cost reduction through automated testing

• Faster identification of issues – issues log available at Cx Kickoff

• Able to test all labs with the “hit of a button” – retesting was made much simpler

• Significantly reduced field hours for all players
