NTP initiated analysisPCOT initiated analysisPOB initiated analysis
NTP is the focus of my talk today
NTP Measure: How is it defined?!What’s been reported at QBR since SFY 2007 Q1• Percentage of projects
which reached NTP before their target bid-let date + 147 days.
• Actual NTP < (target bid let date + 90 window + 57 days for NTP) = “on time”
What the dashboard (and others*) state• Deadline = PS&E Accept
Date + Advt Length + FHWA Review weeks + 27 days for OPL’s activities + 57 days for contract time between bid and NTP
*Eryca McCartin June 2011 memo
