HOW TO USE IT
How to use the Driveway Culvert Cost Calculator
- 1
Choose the diameter and length: The pipe diameter and run length set the pipe cost. Bigger and longer costs more.
- 2
Price the pipe: Steel, concrete and HDPE differ in price. The material factor scales the pipe cost.
- 3
Add excavation, bed and headwalls: Digging and leveling, a gravel or sand bed, and headwalls at each end are fixed lines.
- 4
Add labor and total: Installation hours at the crew rate complete the job. Use the Driveway Culvert Cost Calculator, and confirm permits and engineering before installation.
