General recommendations for planning a pile foundation cannot be given because the costs ultimately depend on the construction project. Therefore, understand the cost examples as a guide and obtain an individual offer for your building project from your service provider.
Composition of construction costs for the pile foundation
The construction costs are made up of various individual items, which ultimately result in the sum of the total costs. Individual items may include:
- Construction report on the soil conditions
- Examination of the beam grating by the structural engineer
- Production of a concrete beam grate
- Reinforcement of the floor slab
- Arrival and departure of the machines
- Flat rate for setting up the construction site
- departure of the excavation
- Level the site with sand
Construction report on the soil conditions
It is advisable to prepare a construction report on the soil conditions, because this way you can determine the need for pile foundations, but also the strength of the piles and the material. You pay around EUR 1,000 net for the soil report.
Examination of the beam grating by the structural engineer
A grid of beams can be concreted over the foundation to distribute the load. You should consult a structural engineer to determine if the additional load from the piling is acceptable. The costs are around EUR 600 net.
Production of a concrete beam grate
If the beam grating is not available or the load-bearing capacity was found by the structural engineer to be insufficient during the test, it must be manufactured. Concrete is used for this. You pay around EUR 4,000 net for the production of such a grating.
Reinforcement of the floor slab
A reinforcement of the floor slab may be necessary if a pile foundation is to be realized for the single-family house. The costs are around EUR 3,000 net.
Arrival and departure of the machines
Special construction machines are required for the pile foundation, which have to be transported to the construction site and picked up again. The prices for this service are around EUR 600 net.
Flat rate for setting up the construction site
The construction site must be prepared for the pile foundation. This includes, among other things, the excavation to drive in the piles. You pay a flat rate of around EUR 1000 net for setting up the construction site.
departure of the excavation
After completion of the construction work, an excavation remains, which usually has to be removed. This service also costs around EUR 1,000 net.
Level the site with sand
The straightening of the building site is important so that further work can follow and you later have the opportunity to create the garden around the family home. Prices for straightening using sand range from EUR 400 to EUR 600.
Calculation of the individual piles
In addition to this basic and preparatory work, the piles are invoiced individually. Various piles can be used for this.
Modern pile foundation with in-situ concrete
Whether the modern pile foundation with in-situ concrete can be used depends on the nature of the ground. However, there are usually no problems. The implementation is realized by a deep excavation. The concrete is poured into this excavation. Accordingly, it is brought to the construction site in a liquid state and processed there. A formwork is used in which the in-situ concrete hardens immediately. The processing is easy on site and different depths of the pile foundation can be realized.
Floating or standing pile foundation
Whether the floating or the standing pile foundation is used in your construction project depends on the soil conditions. With floating pile foundations, the load is transmitted by friction on the lateral surface of the pile. With the standing pile foundation, on the other hand, the load is shifted to a deeper layer of earth.
In terms of costs, the two variants do not differ very much. The preparatory and follow-up work already described is used for both the standing and floating pile foundations.
auger piles
Auger piles are quite inexpensive compared to the other options. You pay around EUR 800 net for each individual post.
Roughened in-situ concrete piles
These piles are calculated by the running meter. This costs around EUR 100 net if the diameter of the posts is 40 centimetres. In addition, it is necessary to cut the height of the in-situ concrete piles. A flat rate of EUR 100 net per piece will be charged for this work step.
Alternative pricing option
The costs for inserting the piles are usually settled with a price per meter. The prices are between 25 and 30 EUR. The material and finish are not included in this price. This means that you have to pay for the craftsman hours as well as the material. Reinforced concrete can be bought quite cheaply, so you can save on construction costs by choosing this material.
Possible total costs for the pile foundation
In any case, the total costs for the pile foundation are in the five-digit range. You already pay around EUR 12,000 net for work that is necessary as part of the preparation and follow-up. The net price does not include VAT. Added to this are the costs for the piles, which are billed by the meter. If material costs and the cost of labor hours are included, the running meter for a cased cast-in-place pile costs 100 EUR. The length of the piles can be several meters. About 20 posts may be needed for a single family home. This results in the following total costs:
- 20 posts, each five meters long = EUR 10,000
- Capping for each post = 2,000 EUR
- Calculation of additional costs = 12,000 EUR
- VAT 19% = EUR 4,560
- The total of the sample calculation is 28,560 EUR.
Thus, the pile foundation is a very high cost factor, which, however, makes it possible to build a single-family house on a rather unsuitable subsoil. The individual total costs for your construction project can deviate from this sample calculation, as they are calculated very individually. In principle, however, you have to reckon with a higher five-digit sum for a single-family house.
