ᐅ Soil survey report – which offer should I choose?

Hello,

I requested quotes for soil surveys from three providers.
The requirements are as follows:

- Structural safety assessment (200 kN/m²)
- Sampling of soil for later chemical analysis in order to arrange soil disposal, initially according to LAGA guidelines

Which of the three offers is the best?

1.)
An investigation of the subsoil with 2 boreholes of 5 m (16 ft) each
and 1 light dynamic probing of 5 m (16 ft).
Summary of the investigation results in a detailed report complying with HOAI requirements.
Includes effort, travel to and from the site, on-site inspections, and the report, all for a flat rate of 650 net.
Testing the infiltration capacity of the subsoil costs 75 € net.
Analysis of a mixed soil sample according to LAGA soil guidelines costs 300 € net.

2.)
Foundation report including:
- travel expenses,
- two small dynamic boreholes in soil classes 1–4 (conditionally 5) up to a maximum depth of 6.0 m (20 ft) below ground level,
- photo documentation of the plot/construction site including access conditions,
- detailed elaboration of results (report preparation).

This service costs 600.00 € net plus 16% VAT.

- Chemical analysis according to LAGA guideline, one sample collection: 255.00 € net

3.) See attachment

Offer 2 is the most affordable.
Offer 1 tests the infiltration capacity of the ground for 75 euros. This is not listed separately in the other two offers.

I believe I have chosen the wrong surveyor.
I commissioned him by email and did not receive any cancellation information.

What are the legal implications? Am I still allowed to cancel the agreement by email?

If you already turn it into a science, how will you ever finish building a house? The contract is signed, let the company do the work. Check if the offer includes 19% VAT, then you can reduce the invoice to 16% if it is completed this year.

He is charging for an inspection that, according to the architect, we do not need, even after we asked. I find this unnecessary money grabbing unpleasant. But I think I will just have the inspection removed.

I’m not trying to make a science out of this. I just don’t want to spend money unnecessarily at every step. I simply don’t know which inspections are sufficient.
