Pavement Management System Update:
Stantec will annually re-survey 33% of the City’s roadway network, approximately
101 centerline miles each year to update the pavement surface condition (PCI)
ratings using CartéGraph’s PAVEMENTiew®Plus software. No data will be
collected on indices other than pavement condition. For each pavement

past construction season, update distress inspection records, and conduct
modeling and analysis of upcoming fiscal year roadway repair plan. This service
