the database. STANTEC staff will update existing work history repair records including 2017
construction season.
QUALITY CONTROL OF FIELD DATA:
STANTEC will provide quality assurance of pavement survey data to ensure data integrity.
STANTEC will field verify 15 centerline miles of roadways for pavement distress, PCI, and
segmentation geometry. STANTEC will also verify existing GIS segmentation for location, street
name, to and from limits, and re-order so model plan ouiput is logically sorted.
PAVEMENT FUNDING IMPACT ANALYSIS:
STANTEC and DPW will review condition findings for pavements and discuss City repair treatment
polices with respect to preservation maintenance and particularly, integration with new
incoming sewer condition data to prioritize objectives for the City's 5 year capital improvement
paving program strategy. Afterwards, STANTEC will analyze 5 year funding models using
CartéGraph’s Navigator pavement condition analysis module. in order to determine precise
funding levels needed to maintain and improve city-wide pavement conditions, the following
actions will be done:
1) Treatments which were previously agreed upon will be considered with up to
date unit costs.
2) STANTEC will allocate funds based on:
a) The current percentage of pavement area which requires routine
maintenance, preservation maintenance, structural improvement, and base
rehabilitation.
b) Pavement management principles to emphasize turning “fair” condition
roads to “good” condition in an effort to prevent exponential future backlog
growth.
SUMMARY OF RECOMENDATIONS:
STANTEC will produce a written summary for City of Nashua officiais which will include tables and
a map showing citywide pavement conditions and up to date recommended 5 year plan of
suggested pavement repair treatments including crack sealing, micro surfacing, patch paving,
and alternative cost-effective treatments.
