ᐅ Construction supervision during building with a general contractor

Hello dear forum community,
we are planning to build a single-family house with a general contractor. The building will be an energy-efficient house 55 built in solid construction with 2 full stories and no basement.

We would like to hire an independent building expert to carry out construction monitoring on our behalf. For this, we have the following questions:

- How often does such an expert need to be present on site?
- At which stages of the construction process must the expert be present?
- What costs can we expect?

Best regards and many thanks in advance

That’s a wise idea and helps prevent unpleasant surprises.
However, it is advisable to seek external and impartial support much earlier. This applies, for example, to the building specification, contract, and especially the building services engineering (heating, domestic hot water systems, ventilation). It is in this area where the biggest shortcomings currently exist. The focus tends to be more on sales than on the necessary precise dimensioning of the system.
As a result, you might think you have purchased a KfW EH55 house on paper, but in reality, you may barely meet the requirements of the energy saving ordinance.

Points a and b depend on the individual construction project (building structure) as well as the planned technical process.
“Critical points” include, for example:
- Foundation work => structural engineering
- Dew point issues
- Airtightness, thermal bridges
...etc.
The costs should correspond to the necessary effort and, in my view, are money well invested.
Not least, being on site also provides (directly or indirectly) valuable information about the overall situation of the contractor.

Best regards.

Hello Sascha,

get a quote from a construction supervisor. A reputable construction supervisor will also provide you with a breakdown of the estimated hours along with their offer. Furthermore, they will give a detailed description of the services they are offering you; if not, stay away.

However, this will cost you a few thousand euros, which will likely be worth it.

Regards
