Curbing is often required when a road is built or rebuilt. Curbing is typically cast-in-place concrete; however, in the Northeast region, granite or other stone material is often used as a curb material. Unit cost is median cost of cast-in-place concrete or granite curb. Concrete curbs may vary due to project size. Roadway projects will have smaller unit cost.
How the Default Unit Cost was Determined
The Vermont Agency of Transportation (VTrans) projects a range of costs for concrete curbing. Cast-in-place concrete curbing is $16-22 per linear foot as part of a larger roadway project and $26-37 per linear foot as part of a sidewalk project. Granite curbing is estimated at $24 linear foot as both the midpoint of concrete curbing and granite cost.
