I am building a single-family house with a 98 sqm (1,056 sq ft) foundation slab. According to the soil survey, I need to excavate 80 cm (31 inches) deep.
Additionally, I have to construct a 20-meter (22 yards) temporary access road, 3 meters (10 feet) wide, with a 45 cm (18 inches) excavation filled with recycled gravel.
The utility lines are located 6 meters (20 feet) away. The excavated soil will remain on the property.
How would you estimate the cost for:
1. Foundation bedding with recycled gravel, 98 sqm (1,056 sq ft), 80 cm (31 inches) deep including frost protection edge.
2. 20-meter (22 yards) temporary access road, 3 meters (10 feet) wide, with 45 cm (18 inches) excavation filled with recycled gravel.
3. Installing utility connections. The lines are located 6 meters (20 feet) away.

Hello Steinbauer,
Of course, you can make estimates here. However, in the end, they won’t be very helpful because costs can vary greatly depending on the region. This applies both to labor and, even more so, to the disposal costs of the excavation material.
What do you plan to do with the excavation material on the property? You will likely have to dispose of most of it, won’t you?
Get concrete quotes from 2-3 local civil contractors, so you know where you stand and where the differences lie.

Roughly estimated, you have 50 cubic meters (cbm) of topsoil (30cm (12 inches) thick) and 60 cubic meters (cbm) of subsoil. That’s quite a volume, but it can still be reasonably distributed (15–30cm (6–12 inches) high). The property doesn’t seem very small either if the construction access road is 20 meters (65 feet) long. Alternatively, you could consider placing the hedge on a small embankment or creating a play hill for the children. What makes sense, however, depends heavily on the specific property. In some cases, it might also be worthwhile to dig a bit less deep and position the house and the access road slightly above the original ground level, then pile the excavated soil next to them.
