Hello,
I received a quote from our construction company for the preparation of a carport foundation:
- 12 pad footings, 40x40x80 cm (WxDxH)
- about 1 meter (3 feet) of drainage pipe (sewer/inspection chamber is right next to it)
- removal of the excavated soil is not included
=> €4,050 including tax
It should be noted that the house connections and the slab foundation are being done at the same time, so the structural builder doesn’t have to make a separate trip just for a few holes.
Is it very naive of me to have expected around €1,000?
They only need to excavate a few small holes and pour about 1.5 cubic meters (53 cubic feet) of concrete into the footing holes during the slab pouring, right?
What costs would you consider realistic?
Best regards

Fightthenew14 Oct 2017 16:14A concrete garage measuring 9m by 3m (30 feet by 10 feet) is not much more expensive either.
Try 6 by 3 meters (20 by 10 feet). Then a width of about 8 meters (26 feet) with the foundation might be possible. My building consultant explained it to me like this: 6 by 3 meters (20 by 10 feet) means you can load two units onto a single truck and transport them without special permits. This cuts the shipping costs in half compared to larger sizes. I find that dimension quite spacious. You can fit a workbench, five wall shelves, two bicycles, a lawn mower, a grill, a wheelbarrow, a refrigerator, winter tires, and still have enough room to move around comfortably inside. Karsten

Use an earth auger to drill the holes. Then, if necessary, place thick pipes into the holes and have them extend slightly above ground level. Make sure everything is leveled. After that, just add reinforcement steel and concrete.
This way, you should be able to manage with the $1000 and still have some money left over for a few cases of beer.

For our carport, we installed 6 foundations. The work was quite straightforward and manageable, and with instructions, it was easy for me to handle.
First, dig holes using a mini excavator, insert reinforcement, build and align a formwork on top. Pour in concrete, place the post anchors, compact the concrete, ensure the correct height, and that’s it.

Regarding digging by hand, using an earth auger, etc., I should mention that there is already compacted gravel on the site, so you’d at least need a mini excavator.
