The use of Subcontractors in the field of demolition of buildings is common practice nowadays. These companies or individuals are often hired to take on specialised tasks. They can be either too complex or too labour-intensive for the main contractors to carry out themselves. However, working with subcontractors in demolition construction presents both opportunities and challenges.
Which contracts do subcontractors fulfil in demolition?
A common job for subcontractors is the complete demolition of buildings. This involves demolishing the entire structure from the ground up, including the disposal of all materials. It requires careful planning and execution to ensure both worker safety and compliance with environmental regulations.
In selective demolition, only part of a building or certain materials are removed. This may be necessary if, for example, a partial building renovation is planned or certain hazardous materials such as asbestos need to be removed. Selective demolition requires precision and attention to detail in order to avoid damage to the remaining structures.
De-cluttering jobs involve the removal of interior fittings and installations, while the exterior structure of the building remains intact. This is often a first step in larger renovation projects. Subcontractors carrying out decluttering work must work carefully to preserve the structural integrity of the building.
What are the tasks?
Demolition subcontractors often specialise in specific tasks. These include, for example, the removal of asbestos or other hazardous materials, the removal of concrete or the demolition of high-rise buildings. Their specialisation enables them to carry out these tasks efficiently and safely. This makes them a great advantage for main contractors.
An important aspect of demolition is the management and disposal of the waste produced. Subcontractors often take on the task of properly sorting, recycling or disposing of waste. This requires not only logistical skills, but also knowledge of legal regulations on the disposal of hazardous waste.
Many subcontractors have specific technical knowledge and specialised machines that are required for certain demolition work. This includes, for example, demolition excavators, concrete cutting machines or even blasting technology. The availability and expertise in the use of such machines make subcontractors valuable partners.
What challenges does this pose?
One of the biggest challenges when working with subcontractors is communication. Misunderstandings and unclear instructions can lead to delays, errors and increased costs. It is important to establish clear communication channels and regular meetings. This ensures that everyone involved is on the same page.
Ensuring the quality of subcontractors' work is critical to the success of a demolition project. Main contractors must set up quality control mechanisms and carry out regular inspections. This ensures that the work meets the required standards.
Demolition work is associated with considerable safety risks. It is crucial that subcontractors take all necessary safety precautions and comply with legal regulations. This includes training workers, providing the necessary protective equipment and implementing safety protocols on site.
Legal framework for demolition work
Particularly strict legal requirements apply to demolition work. As a rule, official authorisations must be obtained before work can begin. There are separate regulations for handling hazardous substances such as asbestos, PAHs or heavy metals in accordance with the German Hazardous Substances Ordinance (GefStoffV) and TRGS 519. Subcontractors must prove that their personnel have been trained and certified accordingly.
There is also the issue of liability: the main contractor is liable to the client for the entire execution - including for errors made by its subcontractors. A clearly formulated Subcontractor contract with clear liability regulations is therefore essential. More on the contractual basis: Service contract vs. contract for work.

Frequently asked questions about subcontractors in demolition
Subcontractors in demolition require different qualifications depending on the task: Training in accordance with TRGS 519 is mandatory for asbestos work. A licence in accordance with the Explosives Act is required for handling explosives. In addition, proof of occupational safety, machine operator licences and, depending on the federal state, trade licences are required.
In principle, the subcontractor is liable for damage caused by its work. However, the main contractor may be jointly and severally liable to the client. Liability should therefore be clearly regulated in the subcontractor contract and proof of sufficient public liability insurance for the subcontractor should be provided.
The disposal of demolition material is strictly regulated in Germany. Mineral waste, pollutants and hazardous waste must be collected separately and disposed of in accordance with the requirements of the Closed Substance Cycle Waste Management Act (KrWG). Subcontractors must keep waste disposal records and are responsible for the proper disposal of waste.
