ᐅ First a soil survey, and now a soil analysis as well?

Hello everyone,

Our house construction has been taking a very long time. Unfortunately, this was not foreseeable from the start, as unforeseen “responsibility issues” with the church came up. They are still involved since we are building under a leasehold agreement. That’s the background.

We tried to complete as many tasks as possible in advance and had our soil survey done for a significant amount in February. Last week, we had our first meeting with the civil engineer and today received a scope of work with this note:

"Please note that a soil analysis is required for the disposal of the soil. However, this is only valid for 3-6 months and must be carried out by the soil surveyor with a sampling protocol according to LAGA 2004. As a result, changes to the soil disposal item may still be possible."


Wait a minute. Does this mean that our soil survey from February can no longer be used for disposal because the “3-6 months” validity period has expired?

Do any of you have more information about this? Unfortunately, I haven’t found anything online about the topic "soil analysis valid only for a maximum of 6 months"...

P.S.: Leaving aside that the rest of our homebuilder’s planning already requires a soil survey quite early so that the basement can be planned promptly. So, it might not be possible to fit this timeframe at all.

Could two things possibly be confused here? A soil survey examines the soil composition and groundwater, which is important for structural engineering. The bath analysis checks for contaminants and similar factors due to disposal requirements.

Could it be that you have confused or mixed up things that don’t belong together here?

A soil report ensures that the house is securely founded and accounts for additional work during foundation or excavation based on the soil classification.
A soil analysis is used to calculate the disposal costs of excess material. It might be that the soil is contaminated and must be disposed of as hazardous waste. This information is required by the landfill.

Well, if it is stated and required by the landfill, then that is the case. Your contract partner knows the acceptance conditions of the landfill for excavated soil, which is probably why it is included there. Only you know exactly what you have commissioned.

Soil analysis and geotechnical report are two different things.

Thanks to @Spunk and @hanse987! That was the right prompt to think differently! I had actually assumed that the soil survey would also include a (chemical) analysis.
