Lesson Learned/Best Practice

The OR’s that Layton is renovating did not meet the required air exchanges before the renovation started. The engineer suggested that Layton take traverse reading to identify duct leaked, however, demo had already begun, and the duct work had already been isolated. Taking traverse reading before demo started would have saved time and money. 

Suggested Actions for Future Projects

During design of the space the EOR must specify exactly what duct, diffusers, equipment, etc must be verifed for the contractor to complete a test and balance survey of the space.  No work of any kind should commence prior to confirmation of the T&B for this space.

Actions Taken / Current Status

Issue has been considered in the EDI improvement team initiative and added to the checklist to insure clear responsibility for this activity
