Legal work that belongs on site early.
Construction projects create legal questions long before a dispute reaches a court. Permits, tender documents, contracts, changes in scope, payment, defects and evidence require a clear allocation of responsibility.
Fritz Zahnd advises clients in public and private construction law, architects’ and engineers’ law, and real estate matters. The focus is on German-Luxembourg projects where technical work and two legal systems meet.
From the contract to the final account
Support can begin with contract drafting and continue through tendering, negotiations, construction progress and, where necessary, proceedings. The aim is to identify the issue while the files are still complete and the project can still be steered.

Cross-border construction projects
German companies working in Luxembourg must consider the local contractual framework as well as operational and tax-related questions. Luxembourg clients with links to Germany face the same challenge in reverse. Advice is available in English, French and German.
Construction and architects’ law FAQs
Questions that come up in practice.
These answers provide a first, general orientation for construction projects in Luxembourg. The contract, project documents, technical circumstances and applicable rules remain decisive.
01What issues fall within construction and architects’ law?
Construction and architects’ law covers the legal framework of a project, from contracts and planning to payment, execution, acceptance, defects and dispute resolution. The relevant rules and parties depend on the project itself.
02Why should the scope of work be defined precisely before construction starts?
A clear specification gives the parties a shared basis for what is owed. It should address the scope of work, interfaces, timing, remuneration, how changes are handled, documentation and acceptance in a way that fits the project.
03How should changes and variations be handled in a construction project?
Changes should, as far as possible, be assessed and recorded before work is carried out. The changed scope, the effect on time and payment, and the agreed route for communication and approval are usually the first points to clarify.
04What is the architect’s role in a construction project?
The architect’s role follows the agreed mission. The OAI model contract for the private sector provides for a written definition of services and, where a full mission is agreed, refers among other things to periodic site checks of whether the works comply with the plans and to informing the client of identified defects.
05What does acceptance mean in a construction project?
Acceptance is a key project milestone. A written acceptance record with detailed reservations helps to record visible issues. Under Luxembourg law, acceptance can also be relevant to the beginning of certain warranty periods.
06What is sensible when construction defects are identified?
Defects should be recorded once identified, notified in writing as soon as possible and assessed against the project record. Depending on the circumstances, a joint report, a bailiff’s finding or an expert assessment may help preserve evidence and clarify the dispute.
07How do the two-year and ten-year warranties differ?
Classification depends in particular on the type of works, the nature and seriousness of the defect, and the legal basis relied upon. For certain construction contracts, the Chambre des Métiers explains a two-year warranty for minor works and a ten-year warranty for certain serious defects in major works; both are assessed from acceptance.
08When can an expert be useful in a construction dispute?
An expert assessment can be useful where the cause, extent, remedial work or cost of a defect is disputed. It does not replace legal analysis, but it can organise the technical facts and evidence.
09Which documents should be kept in order during the project?
Depending on the project, this includes the contract and its attachments, plans and specifications, offers, minutes, change records, correspondence, invoices, photographs and the acceptance report. A complete, up-to-date project file makes later questions easier to assess.
10What requires particular attention on German-Luxembourg construction projects?
Where a project crosses borders, applicable law, contractual and communication language, responsibilities, the permitting context, technical rules and dispute resolution should be considered together at an early stage. Reusing contract templates without checking the project and legal framework is usually not enough.
