Consortium (ARGE)

Consortium (ARGE) - A consortium is an association of several construction companies formed to jointly carry out a construction project. The consortium is established as a civil law partnership (GbR), exists for the duration of the project, and is dissolved upon its completion. All participating companies are jointly and severally liable to the client.

Legal Structure and Liability

The ARGE is formed through an ARGE contract, which governs the distribution of tasks, cost allocation, and management. In practice, the model contract of the German Construction Industry Association is frequently used. Management is handled by a technical lead (responsible for construction execution) and a commercial lead (responsible for billing and accounting).

Since the ARGE is a GbR, all members are jointly and severally liable-in the event of defects or delays, the client can hold any partner fully liable, regardless of that partner’s share of the work. This full external liability represents a significant security advantage for the client compared to a general contractor, where only a single company is liable. Internally among the consortium partners, liability is divided according to the agreed shares.

Areas of Application and Advantages

Consortia are primarily formed for large-scale projects that would overwhelm a single company in terms of capacity, specialized expertise, or creditworthiness. Typical areas of application in the Nuremberg metropolitan region include:

• Large residential construction projects with several hundred units
• Infrastructure projects (bridges, tunnels, sewer systems)
• New hospital construction and school building projects
• Civil engineering works and road construction in combination with building construction

The advantages lie in the pooling of expertise, the distribution of financial risk, and the opportunity to jointly participate in public tenders that require high eligibility criteria (revenue, references, creditworthiness). Individual companies that do not meet these thresholds can still participate in large-scale projects through a joint venture.

Joint Venture vs. General Contractor vs. Individual Award - Comparison

Feature	Joint Venture	General Contractor	Individual Award
Contractual partner of the client	All consortium members jointly	Only the general contractor	Each trade separately
Liability toward the client	Joint and several liability of all partners	Only the general contractor (internal subcontractors)	Separately for each trade
Interface risk for the client	Medium (internal management)	Low (coordinated by general contractor)	High (coordinated by client)
Client’s ability to exercise control	High (direct points of contact)	Medium	Very high
Typical project size	>€5 million contract value	€500,000-€50 million	Any
Insolvency protection for client	Good (multiple liable parties)	Limited	Good for smaller trades

Tax and Accounting Aspects

Since the joint venture is considered an independent civil law partnership (GbR), it must maintain its own accounting records and fulfill tax obligations:

• Separate tax ID number and VAT identification number
• Monthly or quarterly advance VAT returns
• Annual financial statements for the duration of the project
• Profits are distributed to the individual consortium partners on a pro-rata basis and taxed there

In practice, consortia often set up a joint bank account through which all project-related cash flows are processed. Settlements between the consortium partners are made according to the participation ratios specified in the consortium agreement.

Practical Tip for Property Owners in Nuremberg and Franconia

Even for larger renovation projects in the Nuremberg metropolitan region-such as the complete renovation of an apartment building or a roof extension-it can happen that two or more contractors form a joint venture. In such cases, we recommend that property owners insist on a written joint venture agreement and have the joint and several liability of all partners confirmed in writing. This ensures that, in the event of a warranty claim, you are not shuffled back and forth between the companies-a particularly important safeguard for complex projects where interfaces between different trades make potential disputes almost inevitable.

Frequently Asked Questions

What happens if a consortium partner becomes insolvent?

The remaining consortium members are obligated to take over the insolvent partner’s obligations and complete the project. Due to joint and several liability, the client can hold any remaining partner liable for the entire scope of work. Internally, the remaining partners have a claim for compensation against the insolvency estate of the defaulting partner-whether and to what extent this claim is enforceable depends on the financial situation of the insolvency estate.

Does a joint venture need its own tax ID number?

Yes, as a GbR, the joint venture is an independent tax entity. It must apply for its own tax ID number at the relevant tax office and file advance VAT returns. The consortium’s profits are allocated to the individual consortium partners on a pro-rata basis and taxed as business income for them (separate and uniform determination of the tax bases). The consortium itself is not a corporation and therefore does not pay corporate income tax.

How does a joint venture differ from a general contractor?

In a joint venture, the client enters into a contract with the consortium of all participating companies, which work together on an equal footing. All consortium partners are directly liable to the client. With a general contractor, the contract is concluded solely with a single company that engages subcontractors-the client has no direct claim against the subcontractors. The consortium offers the client the advantage of multiple liable partners and greater transparency regarding service delivery, but requires a more complex contractual structure.

What warranty rights does the client have against a joint venture?

Since all joint venture partners are jointly and severally liable, the client can hold each partner individually responsible for the complete rectification of defects-regardless of which partner performed the relevant portion of the work. This is a significant advantage over individual contracting, where interface disputes between trades often result in no company taking responsibility for cross-disciplinary defects. The warranty period for construction work is five years from acceptance. For large-scale projects in the Nuremberg metropolitan region-such as urban infrastructure measures or major residential construction projects-we recommend that clients explicitly stipulate the joint and several liability of all consortium partners in the tender documents and document it in the contract for work and services to avoid future ambiguities in the event of a warranty claim.
