Missing construction documents: request drawings and maintenance information precisely

1. Check the commission and contract date first

Article 7:757a of the Dutch Civil Code concerns construction contracts for a structure. It requires the contractor to provide the client with a dossier when notifying them that the work is ready for handover. The starting point is therefore not simply “sometime after the keys are transferred”. The information must provide full insight into performance of the contract and the work undertaken. See the official text of Article 7:757a.

The Information Point for the Living Environment, IPLO explains two important limits. The statutory duty does not apply to construction contracts concluded before 1 January 2024. Clients and contractors may also agree different arrangements, including what will not be supplied. Start with the actual contract date and complete agreement, including applicable conditions and later variations.

IPLO also makes clear that the name consumentendossier does not restrict the information to private consumers: its explanation covers private and professional clients. This does not make all other protective rules identical for both groups. This guide addresses missing handover information. A pre-2024 contract is not necessarily “without a dossier”; a specific contractual promise can still matter. Conversely, a handover after 2024 does not by itself apply the new statutory rule to an older contract.

2. Look for the completed situation, not just a filename

The statute lists drawings and calculations of the completed structure and its installations, descriptions of materials and installations, and the building's use functions. The starting point also includes information and documents needed for use and maintenance. Their precise meaning must be related to the commission and any agreed deviations; not every conceivable file automatically belongs in every project.

For a drawing, check the component it describes, its date or revision and whether construction changes are incorporated. A folder containing several similarly named PDFs may remain unclear. Ask which version the contractor identifies as the handover version. Calling a file “final” is not independent technical proof that its contents are correct.

The ministry-commissioned SME handover-dossier guide helps organise this. Its document lists distinguish, among other things, not applicable, agreed and supplied at handover. They also ask for origin, document number and revision date. Use that structure as a tool; the brochure is not a new legal guarantee that you can demand every listed certificate or photograph.

3. Distinguish three kinds of missing-document questions

Record what you actually received before requesting an entire replacement set. Separate a wholly missing document, a supplied version that cannot be matched to the work, and information you would additionally like. These questions have different starting points. Explain the document's relevance to the particular work: operation, maintenance, checking a variation or investigating a possible defect.

Place responses beside this list. “Not applicable” may have a substantive reason, but ask what it is. A document might fall outside the commission or within an agreed exclusion. The same response might also conceal an error if the installation was supplied. Assess the explanation instead of treating every abbreviation as either a refusal or a sufficient answer.

4. Request use and maintenance information suited to the building

Information is useful only when it identifies the supplied component. Note, for example, the installed make and model, the available instructions associated with it and maintenance details you cannot locate. The guide has separate lists for materials, installations and use and maintenance instructions. Its introductory explanation says it can serve new-build and renovation projects, adapted to the actual commission.

Do not use a general internet list to demand complete foundation documentation when only a bathroom was renovated. Conversely, a limited commission may still require relevant installation information. IPLO provides an example of missing central-heating drawings for an added storey. Its conclusion depends partly on there being no different agreement; it does not prove your contract has the same contents.

Do not experiment with unfamiliar settings or installations to find out whether missing documentation matters. Ask a technical expert what information is needed for safe operation or maintenance. That explanation differs from a legal opinion on a disputed delivery duty. Receiving a manual also does not itself prove sound installation or that a stated warranty covers every future problem.

5. Do not confuse the client dossier with municipal records

IPLO expressly states that the municipality and quality assurer are not involved in the client dossier. It concerns the contractor-client relationship. Some information may overlap with an applicable public-law completion notification, but the functions differ. A municipal reference therefore does not establish that the contractor handed you the agreed maintenance information.

An agreement not to provide a client dossier also does not automatically remove public information duties. IPLO warns that the client may then lack information needed for completion notification. The applicable public procedure must be determined separately. Our guide to Wkb completion notification before occupancy addresses that subject; this text adds no exemption, waiting period or moving date.

Keep three questions visible: what must the contractor give you under contract or law, what was actually received, and what is needed for a separate procedure? One certificate does not automatically answer all three. Ask the relevant party which document serves which purpose, especially where someone refers to “the Wkb dossier” without explaining its contents.

6. Turn “the dossier is missing” into an assessable request

Address the contractor who is your contracting party. Identify the project and agreement, list missing items and refer to the folder or revision list supplied. Explain which question remains unanswered. Request delivery or a specific explanation if the contractor says the document does not belong in the handover.

Example wording for your own document request

When you announced readiness for handover, I received your folder dated [date]. For [component], my list shows that [document or identifiable current revision] is missing. The contract states [agreement]; I want to establish which information relates to the completed work. Please provide the missing document or explain why you consider it outside the agreed or applicable handover. Please also identify the versions belonging to the handover set.

This example is not an official notice of default and fixes no universally appropriate remedy period. The next step depends on the due obligation, earlier communications, the response and the particular interest. Keep your request and the explanation received. If alleging a defect or financial consequence, describe and substantiate it separately; absent documents do not automatically prove all alleged losses.

7. The counterargument: the work is good, so why more paperwork?

It is understandable that the contractor wants to finish and that clients do not need an extensive technical archive for every small component. An unclear document is not necessarily a construction defect either. Our argument is therefore not that the largest folder proves the best handover. The question is whether information about the agreed work, use and maintenance is sufficiently identifiable and useful.

This counterargument does not justify ignoring missing items. A correctly installed component can be difficult to maintain later if nobody can identify the model or configuration supplied. Conversely, a complete folder does not repair defective work. Separate information and technical-quality questions so each reaches the appropriate expert.

If practical delays arise, ask what is available, what will follow and how that will be documented. A workable arrangement is not automatically a waiver; a broad declaration that everything is complete must nevertheless reflect actual delivery. Our guide to preparing for handover covers broader inspection and recording. Have refusal of handover, withholding payment and other financial pressure assessed separately.

8. Fictional example: Lotte receives three drawing revisions

In this invented example, Lotte commissions an extension with a changed heating layout. Her contract was concluded after 1 January 2024. When notified that the work is ready, she receives a digital folder containing three drawings. One shows the old installation location; it is unclear which of the other two represents the completed work. A generic brochure covers several models.

Lotte does not immediately claim that every document is absent or that she owes no further payment. She connects her question to the agreed variation, asks which drawing is the handover version and which operating and maintenance information belongs to the installed model. She also checks whether her contract contains different dossier arrangements. Any technical problem is described separately.

This fictional example predicts no right to every file, damages or refusal of the entire work. It shows how a specific comparison can replace a general complaint. The date alone does not answer everything; commission, agreements, information supplied and the contractor's response must be read together.

9. Keep a handover card beside the original files

Make your own list without overwriting original documents. Record which revision arrived when, what is missing and which answer you await. Identify later supplements as supplements rather than pretending they were present initially. This article stores no project information and calculates no period or amount.

• Check contract date and agreements before applying the statutory rule.
• Compare documents with the work actually agreed and completed.
• Separate missing, unclear and additionally desired information.
• Request usable revisions and details for the relevant operation and maintenance.
• Keep original files, requests and supplements with dates.
• Have technical uncertainty, handover and financial consequences assessed separately.

For questions about the underlying agreement, see checking the construction contract. A building expert and legal adviser have different assignments. Explain which problem you want solved so a document request does not become an unfocused argument about all construction costs.
