Hello,

I’m not sure if this is the right place to ask. After contacting all demolition companies within about 100 km (60 miles), we either received no response, extremely overpriced quotes (about double what a similar property cost three years ago), or information that the earliest service might be in 2017 or 2018. My husband and I are now also considering foreign companies.

Does anyone here know demolition companies that offer reasonable prices for demolitions on a steeply sloped site within a town or city?

Complex demolition situation: A demolition application must be submitted through an architect. Demolitions exceeding a certain volume—in North Rhine-Westphalia 300m3 (10,594 cubic feet)—require a building permit or planning permission. In complex demolition cases—within built-up areas, adjacent to neighboring buildings, etc.—a demolition structural report may be necessary. The demolition company must be certified, for example, a member of the German Demolition Association, and must provide the building authority with proof of qualifications and equipment. The disposal of all demolition materials, along with waste disposal documentation, must be recorded if required. I am confident that foreign companies have no chance and are not cheaper. Demolition is not for unskilled or unscrupulous contractors but is often a demanding engineering task that requires great care. Current prices are approximately €35-55 (gross) per cubic meter (1.3–1.9 cubic yards) of enclosed space (North Rhine-Westphalia), provided no extensive hazardous waste disposal is involved (asbestos-containing materials). If prices are significantly lower, it is likely to be borderline illegal. Also contact local civil engineering and structural construction companies, as they sometimes offer demolition as a preliminary service.

Architect’s estimate is 25,000 to 30,000. This is also the estimate given by two demolition contractors after site inspection. Both of them say the same thing. You know, I can earn my money more easily at the moment.

Currently, there is a subsidy for construction measures on inner-city plots with vacant buildings. The subsidy is meant to cover the difference between demolition costs and land value. Agricultural outbuildings and the slope of the land were taken into account. There is no flat terrain. Then we would be at 45,000.

The seemingly lowest offer we have is 62,000 in a lump sum, without a detailed breakdown of what is included. To be precise, it is not even clear whether disposal is included or not.

Something doesn’t add up.

As of today, demolition structural analysis is not required.
The architect will obtain the demolition permit.

One lane of the road must be closed while the residential building is being demolished.
The application will only be submitted once we have a date. This will probably all be handled by a traffic management company that we will hire, as it will either be regulated with traffic lights or a detour for a few days will be necessary.

In inner-city areas with slopes, often a “maybe next year” answer is given, which doesn’t help either. We don’t want to pay more than double the estimate and almost double what the municipality paid, and that’s likely what it will come down to.

Is it possible to roughly assign price ranges to different buildings made of various materials?

If you have already hired an architect, they should include the demolition work in the bill of quantities. Although this incurs an architectural fee, it ultimately leads to comparable bids that are also broken down into individual items. As always: the most savings come from detailed planning.

Comparable would already be an improvement, regardless of the price level.

Is this similar to a tender process like those used by public authorities, whether for construction or machinery procurement?

Yes, all construction services are clearly described both quantitatively and qualitatively, including secondary services or special services. With carefully prepared bills of quantities (BOQ) based on prior quantity surveying, the items usually correspond closely to the actual execution. For tasks such as demolition, there will inevitably be some unforeseeable work charged on an hourly basis. This is unavoidable. However, the architect should have already provided you with detailed information about this, as that is part of their role.
