Reference: 3-Year Optional Pavement Management Support Services Proposal
Dear Mr. Dookran:
Per your request, Stantec Consulting Services, Inc. (Stantec) has prepared the following
Pavement Management Services Proposal to ensure and protect the City’s municipal
pavement management system investment with providing system maintenance services
to maintain the City’s pavement management database system.
We hereby propose to maintain the City’s Cartegraph pavement management system
(PMS) in Cartegraph's Navigator, Stantec will update work history, conduct pavement
conditions surveys, and perform data modeling and analysis on behalf of the City.
Stantec will maintain the City's pavement management database and provide exports
compatible with your GIS.
Below are specific work tasks proposed to support Nashua in continuing their pro-active
approach to managing its pavement assets. The intent of these tasks will be to update
the City's pavement management database on an annual basis by utilizing ongoing
asset facility distress surveys, conduct data analysis for future capital improvement
planning and monitor system-wide metrics on Nashua's roadways.
WORK TASKS:
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 PAVEMENTview@Plus software. No data will be
collected on indices other than pavement condition. For each pavement
segment, Stantec will capture a digital picture image and link to the database.
Stantec staff will enter and update new work history repair records for the past
construction season, update distress inspection records, and conduct modeling
and analysis of upcoming fiscal year roadway repair plan. This service includes
attendance at one (1) meeting at Nashua DPW, a written annual summary
describing Nashua's pavement condition network and financial needs, and GIS
shapefile export.
