Trench length 20 m; width 0.6 m; depth 1.2 m; pipe OD 200 mm
Excavation 14.4 m³; pipe displacement about 0.628319 m³; backfill about 13.771681 m³A 200 mm outside diameter equals 0.2 m. The 20 m cylindrical pipe displaces about 0.628 m³ of the rectangular excavation.
Trench length 10 m; width 0.5 m; depth 1 m; pipe OD 100 mm
Excavation 5 m³; pipe displacement about 0.078540 m³; backfill about 4.921460 m³The calculated remainder excludes only one pipe. It is not yet adjusted to represent delivered loose soil or compacted fill.
Questions & answers
Can I use the result directly to order truckloads of fill?
Not without accounting for the specified bedding zones, supply material, wastage and loose-to-compacted volume factors. This is geometric trench volume.
What if there are two pipes or manholes?
The current formula subtracts only one round pipe. Estimate additional displacements and separate chambers explicitly rather than relying on this output as a complete bill of quantities.
