subcontractor

Subcontractor - A subcontractor is a construction company that is hired by a general contractor to perform specific tasks within a construction project. The subcontractor has no direct contractual relationship with the building owner-its client is exclusively the general contractor. This structure is standard in the construction industry: A GC secures the overall contract and awards individual trades (electrical, plumbing, facade, etc.) to specialized subcontractors.

Legal Status

The subcontractor has a contract for work and services with the general contractor, not with the building owner. Consequently: The building owner can only file a claim for defects with the general contractor, not directly with the subcontractor (no contractual relationship). The general contractor is liable to the building owner for the work of its subcontractors as if it were its own fault (Section 278 of the German Civil Code). The subcontractor’s claim for payment is against the general contractor-if the general contractor becomes insolvent, the subcontractor is often left without payment.

Important to understand: The building owner cannot therefore directly claim damages or warranty from the subcontractor. They must hold their general contractor accountable, who will then seek recourse from the subcontractor internally. This indirect route can be time-consuming and difficult in practice if the general contractor has gone bankrupt.

Risks for Building Owners

The main risk for building owners lies in the insolvency of the general contractor: Subcontractors who have not been paid may leave the construction site, leaving the building owner with a half-finished building. Additionally, quality control is more difficult when the general contractor is solely responsible for selecting subcontractors and may choose the cheapest rather than the best provider.

Another risk: illegal labor and employment within the subcontractor chain system. With the Act to Combat Illegal Labor (SchwarzArbG), lawmakers have tightened the liability of general contractors for the conduct of their subcontractors. Building owners should insist that the general contractor only employs subcontractors with verifiable social security documentation and compliance with the minimum wage.

Subcontractor List and Contractual Obligations

Reputable general contractors disclose their list of subcontractors and work with established partners. Building owners should stipulate the following points in the construction contract with the general contractor:

• Subcontractor List: The general contractor must list all major subcontractors and provide timely notice of any changes.
• Proof of Qualifications: All subcontractors must provide proof of the required expertise and certifications.
• No right to subcontract without consent: The general contractor may not subcontract any major trades without the client’s consent.
• Surety bond: A performance bond and warranty bond from the general contractor provide protection in the event of insolvency.

Chain of Subcontractors: Risk of an Extended Subcontractor Chain

In practice, subcontractors sometimes subcontract portions of the work to further subcontractors-a chain that makes quality control and liability increasingly unclear. Building owners should include a clause in the general contractor agreement prohibiting subcontracting to third-tier subcontractors (sub-subcontractors) without consent. This is legally permissible and common in well-drafted construction contracts.

Practical Tip for Building Owners in Nuremberg

We recommend that building owners in the Nuremberg metropolitan region include the following provisions in their construction contract with the general contractor: A clause obligating the general contractor to name the subcontractors and report any significant changes; a surety bond (contract performance bond and warranty bond) as protection against the general contractor’s insolvency; the client’s right to demand a change in the event of obvious quality issues with a subcontractor.

Nuremberg has a vibrant community of tradespeople-take advantage of the opportunity to check references for the subcontractors being used. An experienced local architect or construction manager knows the quality of regional businesses and can help in selecting a reliable general contractor.

Frequently Asked Questions

As a building owner, can I negotiate directly with the subcontractor?

Generally, no-your contractual partner is the general contractor. Direct instructions to subcontractors can even be legally problematic (bogus self-employment, breach of contract). If you wish to influence the execution of the work, do so through the general contractor or an independent construction manager.

What happens if the general contractor becomes insolvent?

If the general contractor becomes insolvent, the subcontractors may cease work. The building owner must then either involve the insolvency administrator or commission the subcontractors directly (which requires new contracts). A performance bond (typically 5-10% of the construction cost) covers part of the loss.

Is the subcontractor liable for warranty claims to the building owner?

The subcontractor is liable for warranty claims only to the general contractor as its contractual partner. The client can only assert warranty claims against the general contractor, who then passes these on internally to the subcontractor. It is advisable to include a clause in the construction contract that obligates the general contractor to assign its warranty claims against subcontractors to the client.

How can I, as a client, protect myself against subcontractor risks?

The most important protective measures are: a clearly worded general contractor contract with a guarantee obligation, a retention of 5-10% of the final invoice amount until the expiration of the warranty period, and the agreement on a list of subcontractors subject to approval. In addition, independent construction supervision by an architect or civil engineer protects against quality issues arising from unsuitable subcontractors.

Subcontractors and the Warranty Chain

An often-overlooked aspect of the subcontractor relationship is the warranty chain: The general contractor owes the client a five-year warranty under the German Civil Code (BGB) or a four-year warranty under the VOB/B. Internally, the general contractor also has warranty claims against its subcontractors-with comparable time limits. However, if the general contractor becomes insolvent in the second or third year after completion, its warranty claims against the subcontractors do not automatically expire, but the practical path to enforcement for the client becomes considerably more difficult.

To remain capable of taking action in this case, we recommend including an assignment clause in the general contractor agreement: The general contractor assigns all claims for defects to which it is entitled against its subcontractors to the building owner as a precautionary measure upon conclusion of the contract-subject to the condition precedent of the general contractor’s insolvency. Such a clause is legally permissible and provides the building owner with a direct means of enforcing claims against the contractors even in the event of insolvency. We recommend that building owners in the Nuremberg metropolitan region engage a lawyer specializing in construction law to draft the general contractor agreement, ensuring that such protective clauses are incorporated in a legally sound manner.
