Description
The City of Wilmington is soliciting proposals to conduct a comprehensive pavement and sidewalk condition survey for its entire municipal road network (≈ 400 centerline miles) and sidewalk network (≈ 377 miles). The selected vendor will use an image‑based, GPS‑geotagged mobile platform to collect 360° HD imagery, distress points, dimensional data (width, curb/gutter dimensions, crosswalk slopes), and will deliver the results in an ESRI Geodatabase compatible with the City’s StreetLogix asset‑management system. The scope also includes a technical report recommending updates to the city’s pavement restoration fee.
• Required methodology follows ASTM D6433‑11 (PCI survey) – ASTM E3303 is not acceptable.
• Deliverables: GIS‑ready geodatabase for pavement and sidewalks, high‑resolution imagery, distress catalog, and a restoration‑fee recommendation report.
• The contract will be awarded on a firm‑fixed‑price/lump‑sum basis; the vendor must provide line‑item costs for data‑collection, distress analysis, width measurements, curb/gutter dimensions, crosswalk slopes, sidewalk survey, and restoration‑fee consulting.
