In short

The DOE gathers the documents describing what was actually built. Contents, who is responsible, when to submit it, risks if it is late: what the contractor needs to plan for.

DOE: what does “as-built works file” mean and what is it used for?

The DOE (dossier des ouvrages exécutés), or as-built works file, is the file that describes what was actually built on a site. Each contractor submits it for its own trade package at the end of its work. The client, meaning the person for whom the structure is built, uses it to operate, maintain and modify the building.

The DOE for works has no single form, because it is defined by the contract documents. The CCTP (cahier des clauses techniques particulières, the special technical specifications) sets out the technical documents to be supplied. The CCAP (cahier des clauses administratives particulières, the special administrative specifications) sets the administrative rules, including the submission of documents. In a public contract, the CCAP may refer to the CCAG Travaux, the general administrative specifications applicable to public works contracts. In a private contract, the agreement may refer to the reference standard for private building contracts. That standard applies only if the contract mentions it, and you then need to check which version it refers to. The first thing to read is therefore always your own contract documents.

The file serves as a reference document because the project changes during the works. A pipe is rerouted, a piece of equipment is replaced with an equivalent model, a partition is moved. The DOE records the final state, not the planned state.

What is the DOE used for in practice?

  • Locating a structure: knowing where a duct, cable or drain runs before drilling or demolishing.
  • Replacing a part: finding the exact reference of a piece of equipment without taking it apart to read its plate.
  • Maintenance: applying the manufacturer's instructions and maintenance schedules.
  • Making a warranty claim: having the manufacturers' warranties and the certificates that document what was installed.
  • Transforming the building: starting from up-to-date plans for a refit or an extension.

Take a common case. A plumber moves a drainage stack to get around a beam, without the original plans being corrected. If the DOE does not show this route, the contractor who later works on the slab risks drilling through the pipe.

What is the DOE in practice for a company owner?

It is a deliverable in its own right, like the final invoice. It is prepared during the works and checked before acceptance. Depending on the contract terms, it may be a condition of acceptance or of final payment. Treating it as a last-minute formality exposes the owner to delayed payment and a strained relationship with the client, where the contract links these items.

Key takeaways The DOE describes the structure as it was executed, not as it was planned. It allows the client to operate, maintain and modify the building. Its exact contents and submission terms are found in the contract documents (CCTP, CCAP, contract) and in the texts they refer to. It is prepared during the works, not in the last few days.

What does a building DOE contain?

A building DOE brings together the documents needed to know, use and maintain the structures built. The list below is a common baseline, not a uniform obligation: each contract sets its own requirements, package by package. The contractor confirms it in the CCTP, the CCAP or the contract before putting its file together.

  • As-built drawings (plans de récolement): graphic documents showing the structures as executed, with their changes compared with the original plans.
  • Technical data sheets for the materials and equipment actually installed, with their references.
  • Maintenance and servicing manuals for the equipment, so that the operator knows how to use and maintain it.
  • Certificates and conformity attestations issued for products, installations or structures, when the contract requires them.
  • Test and inspection reports produced during or at the end of the works.
  • Manufacturers' warranties on the equipment and materials concerned.

Does the DOE content change from one trade package to another?

Yes, significantly. A package's DOE depends on the structures installed and on what the contract requires for that package. The table below gives common trends, to be confirmed in the documents of each contract.

Main DOE documents by trade package
PackageDocuments often emphasized
PlumbingNetwork diagrams, equipment manuals, test reports
ElectricalDiagrams, circuit identification, certificates related to installations
Structural workUp-to-date execution drawings, certificates for the products used
RoofingManuals and position plans for equipment installed on the roof, for example a lifeline

Common trends, not binding: the exact list is in the CCTP, the CCAP or the contract of each operation.

What formal requirements apply when submitting the DOE?

The contract may regulate the presentation: paper, digital files or both, number of copies, drawing format, organization into folders by package. Even when nothing is imposed, a readable file is submitted faster. Each document bears the name of the site, the package and the contractor, and the sheets follow the order of the list of required documents.

Do not rely on a generic list A list found online does not replace the CCTP, the CCAP or the contract. Reread these documents package by package as soon as the contract is signed and note each required document, its format and its recipient.

In a private contract, the signed agreement and its appendices play the role of the CCTP and the CCAP. When a requirement remains unclear, the contractor asks the project manager for a written clarification before the end of the works. Example: the CCTP requires a test report on a network, but the test takes place after the crew has left. If nobody is responsible for collecting the document, it is missing at submission. One line in the document list, with a name and a deadline, prevents this oversight.

Who prepares the DOE, who submits it and to whom?

Each contractor prepares the part of the DOE that corresponds to its package. It gathers the as-built drawings, data sheets, manuals, certificates and reports relating to its own structures. It is best placed to produce them, because it knows what it installed and under which references.

The DOE submission route depends on how the contract is organized. When a subcontractor is involved, it submits its part to the main contractor, which integrates it into its own file. The main contractor then sends the whole to the project manager (maître d'œuvre), who is in charge of design and supervision of the works, or directly to the client, depending on the contract. The project manager often checks the completeness of the file before passing it on, but this task is read from their contract and from the contract documents.

  1. The subcontractor or supplier submits its documents to the contractor holding the package.
  2. The contractor holding the package checks and assembles the file for its package.
  3. It sends it to the project manager or to the client, depending on the contract.
  4. The recipient checks completeness and flags what is missing.
  5. The contractor corrects and completes the file, then has the submission confirmed in writing.

Who is responsible for the DOE in a company of a few employees?

In a small building company, the DOE often has no dedicated department. The owner remains responsible for submission to the client, but appoints a person who follows the file site by site: works supervisor, site foreman, administrative assistant, or the owner personally when they run their own sites. Two rules prevent oversights. The name of the person responsible appears in writing in the site file, with the list of documents to be supplied. And the installation crews hand over a report, a sheet or a photo the same day, rather than keeping them in a vehicle or on a phone.

How does a subcontractor submit its DOE?

Subcontracting is, according to the BOFiP, the operation by which a contractor entrusts, by a subcontract and under its own responsibility, all or part of the performance of the works contract to another person called the subcontractor. The subcontractor therefore relies first on its subcontract, which should specify the expected content, the submission format, the deadline and the contact person at the main contractor. If the contract is silent, it takes up the requirements of the main contract and confirms them in writing. The main contractor remains the client's point of contact: it sets internal deadlines well before the date expected by the project manager.

What does the project manager check when receiving the file?

Checks usually cover the presence of the documents listed in the contract, the legibility of the documents and the consistency between the as-built drawings and the site. A drawing that does not match the visible structure goes back to the contractor for correction. It is better to review the file on site before sending it, with the works supervisor.

What is the difference between the DOE, the DIUO and the as-built drawing file?

The DOE, the DIUO and the as-built drawings (plans de récolement) are three distinct notions that are often confused. The DOE is the file of the structure as executed, prepared by the contractors. The DIUO (dossier d'intervention ultérieure sur l'ouvrage, the file for later work on the structure) concerns the safety of those who will work on the building later. The as-built drawings are graphic documents that form part of the DOE.

DOE, DIUO and as-built drawings: three documents not to be confused
DocumentPurposeWho usually prepares itLink with the DOE
DOE (as-built works file)Describe the structure as built, to operate and maintain itThe contractors, each for its packageOverall document
DIUO (file for later work on the structure)Gather the information useful for the safety of future work on the structureMost often the health and safety coordinator (SPS), when the site has one, with the information supplied by the parties involvedSeparate document, sometimes fed by the same information
As-built drawingsRepresent graphically the structures as executedThe contractors, for their structuresDocuments that form part of the DOE

The details of the requirements for each file are checked in the contract documents and in the texts applicable to the operation, including the French Labour Code for the DIUO.

The three documents are not interchangeable. A set of as-built drawings, however carefully made, is not a complete DOE: the data sheets, manuals and certificates are missing. A complete DOE does not replace the DIUO either, which serves another purpose, preventing risks during future work.

Is there a DIUO on every site?

No. The French Labour Code organizes health and safety coordination (SPS) on building sites involving several contractors, and the DIUO falls within that framework. It is therefore tied to the presence of an SPS coordinator. On a site without a coordinator, this file is not prepared on that basis. The contractor does not assume it: it checks in its contract documents whether a coordinator is appointed and what they expect from it.

Information from one document can feed the other. The as-built drawings and manuals supplied by the contractors help fill in the DIUO. To know what it must supply for each, the contractor rereads its contract and asks the project manager or the coordinator, rather than assuming that submitting one file covers the other.

A frequent case: a roofer installs a lifeline and anchor points. Its manuals and position plans are in its DOE, but they also serve whoever fills in the DIUO, because future roof workers need them. The contractor supplies these documents as soon as its package is finished, without waiting to be asked a second time.

When should the DOE be submitted in relation to acceptance of the works?

The timing of DOE submission depends on the contract. Depending on the contract documents, the contractor submits it before acceptance of the works, at acceptance or after. Acceptance is the act by which the client declares that it accepts the structure, with or without reservations. No single rule applies to all sites, and a deadline found online does not replace reading the contract.

What is the link between the DOE, acceptance, final payment and the retention?

The sensitive point is the link between acceptance, reservations and payment. In a public contract, the CCAP and the CCAG Travaux to which it may refer govern acceptance and final payment. For this type of contract, the public procurement section and the page on solutions for public works give additional guidance.

In a private contract, the agreement and, if it refers to it, the reference standard govern these stages. The retention (retenue de garantie), a sum held back by the client, follows a legal framework there: the contract states the retention provided for and the conditions for its release, detailed in the dedicated article on the retention. The DOE affects these stages only if the contract organizes it that way. If it makes the DOE a condition of acceptance or of final payment, a missing file can block them. If it provides for submission after acceptance, the delay weighs rather on the reservations or on possible penalties.

Where can the DOE submission deadline be found in the contract documents?

Where to look for the DOE submission deadline
Document to openWhat to look forContract concerned
CCAP or signed contractThe article on acceptance, the deadline for submitting documents and any link with final paymentPublic, and private when the contract includes them
CCTP, package chapterThe documents to be supplied for the package, their format and number of copiesPublic and private
Service order or execution scheduleA complete-file milestone date set during the worksPublic and private
Site meeting minutesClarifications or changes agreed with the project managerPublic and private
SubcontractThe internal deadline imposed on the subcontractor, earlier than that of the main contractBoth

If the documents contradict each other or are silent, ask the project manager for written confirmation before the end of the works.

What if the DOE submission deadline remains unclear?

  1. Note the passages of the CCAP, the contract and the CCTP that deal with the DOE, acceptance and final payment.
  2. List any contradictions between these documents.
  3. Write to the project manager to ask for the deadline and the submission conditions.
  4. Have the answer recorded in site minutes or a dated letter.
  5. Set an internal complete-file date earlier than the one that was confirmed to you.

Anticipate rather than discover the deadline at acceptance Note the DOE submission rule as soon as the contract is signed. Set an internal complete-file date, earlier than the date expected by the client. Tell your subcontractors about this date as soon as their contract is signed.

What does the contractor risk if the DOE is late or incomplete?

A DOE that is submitted late or incomplete exposes the contractor to several possible consequences. Their extent depends on the contract terms: the same delay may have no consequence or may block the closing of the site. The table below links each risk to the condition that makes it real.

Risks of a late or incomplete DOE and conditions for them to occur
RiskConditionWhere to check
Reservations at acceptanceThe client accepts the works with reservations that mention the missing fileCCAP or contract, acceptance report
Final payment or retention delayedThe contract links final payment or release of the retention to lifting the reservations or to submitting the DOEPayment and retention clauses
PenaltiesThe contract provides for them for late or incomplete submission of documentsPenalty clause of the CCAP or contract
Repeated remindersThe project manager flags gaps several timesSite minutes, letters
Strained relationshipDelays recur, with a possible effect on later contractsFeedback from the project manager or the client

These risks are contractual scenarios: none applies automatically without a corresponding clause.

Some contracts expressly link payment of the final balance to submission of the DOE, others treat the subject more flexibly. The answer to the question of final payment is therefore found in the signed clauses, not in a general rule applied without reading them.

What is the retention and how can a missing DOE delay it?

The retention (retenue de garantie) is a sum withheld from payments and held by the client to guarantee that reservations are lifted, over a period tied to acceptance. In a private contract, its rate is set by law, and its release is read from the contract.

Imagine a package that finishes its works and issues its last invoice. The project manager notes that the test reports are missing and lists them among the reservations. If the contract makes lifting the reservations conditional on submitting these documents, the retention stays in place until they are supplied. To understand this mechanism, see the article on the retention in construction works. To track payments during the works, also see the progress payment statement.

Reread the clauses as soon as the contract is signed Find in the contract or the CCAP the clauses on the DOE, penalties, final payment and the retention. Note the conditions for lifting reservations. If in doubt about a clause, seek legal advice before committing.

The best protection remains prevention. A contractor that knows its obligations from the start and tracks the progress of its file limits the risk of a blockage when it is waiting for payment.

How can you build the DOE throughout the works rather than in a rush?

Building the DOE throughout the works requires a simple method, applied as soon as the contract is signed. The contractor lists the required documents, appoints a person responsible, collects documents as the phases progress, archives them by package and reviews everything before acceptance.

  1. List the required documents: reread the CCTP, the CCAP or the contract, then draw up the list of expected documents per package, with format and recipient.
  2. Appoint a person responsible: a works supervisor, site foreman or administrative assistant follows the file and chases subcontractors. In a very small company, the owner can take this role, provided it is put in writing.
  3. Collect as the phases progress: data sheets at procurement, certificates at the end of a phase, reports on the day of the tests, photos before structures are closed up.
  4. Archive by package with the same filing system from one site to the next.
  5. Review before acceptance: compare the file with the initial list and correct any gaps.

What is an example collection schedule for a plumbing package?

Fictional practical case: a plumbing company works on a residential building. The deadlines below are relative markers to be adapted to the contract documents.

DOE collection schedule for a plumbing package
DeadlineActionDocument collected
At signatureReread the CCTP and the CCAP, draw up the document list, appoint the person responsibleList of required documents, filled in line by line
At procurementRequest documents from suppliersData sheets, manufacturers' warranties
Before ducts are closedPhotograph the networks, annotate the plansDated photos by zone, modified plans
On the day of the testHave the report signedNetwork test report
Well before acceptanceReview the file with the works supervisorAs-built drawings, maintenance manuals
Before acceptance, on the set internal dateSend to the project manager and have it confirmed in writingComplete file, acknowledgment of receipt

Fictional example to illustrate the method, with no value as a regulatory deadline.

What tools help track DOE collection?

A site management tool makes this collection easier by centralizing on site the documents and photos of each package. To align collection deadlines with the progress of the works, the site schedule in Excel can serve as a basis. For a public contract, the requirements are in the contract documents: find guidance in the guide to bidding on public construction contracts. The works supervisor checks the progress of the file at each site meeting, and the owner verifies completeness before the submission date.

Frequently asked questions

What is a DOE in building works?

The DOE is the file that describes what the contractors actually built: as-built drawings, data sheets, maintenance manuals, certificates, test reports and warranties. The client uses it to operate and maintain the building.

What does DOE mean in the construction industry?

DOE stands for “dossier des ouvrages exécutés”, the as-built works file. The word “exécutés” (executed) indicates that the file documents what was built, not what was planned on the drawings. Its exact contents remain set by the contract.

What must an as-built works file contain?

The usual contents include as-built drawings, data sheets, maintenance and servicing manuals, certificates and conformity attestations, test reports and manufacturers' warranties. This list is neither universal nor mandatory for all sites. The contractor confirms it package by package in the CCTP, the CCAP or the contract, and in the texts they refer to (CCAG Travaux for a public contract, the reference standard if a private contract refers to it).

Who must submit the DOE: the contractor, the project manager or the client?

Each contractor prepares the part of the DOE that concerns its package. It then submits the file to the project manager or directly to the client, depending on how the contract is organized. The project manager often checks the file before passing it on, but it is the contractor that produces it.

Within what period must the DOE be submitted after acceptance of the works?

The period depends on the contract: the DOE may be requested before acceptance, at acceptance or after. Look for the deadline in the CCAP (article on acceptance, mention of a deadline for submitting documents), in the CCTP chapter devoted to your package, in service orders and in site minutes. If it does not appear clearly, ask the project manager for written confirmation.

What is the difference between the DOE and the DIUO?

The DOE describes the structure as executed and is used to operate and maintain it. The DIUO (file for later work on the structure) concerns the safety of those who will work on the building later and falls within the SPS coordination provided for by the French Labour Code. The two documents are distinct and do not replace each other.

Must a subcontracting craftsperson supply a DOE to the main contractor?

In principle, the subcontractor submits the documents for its package to the main contractor, which integrates them into its file. The terms are found in the subcontract: content, format, date and contact person. If nothing is specified, take up the requirements of the main contract and confirm them in writing.

Can final payment be withheld if the DOE is not submitted?

It depends on the contract terms. Some contracts link final payment or release of the retention to submission of the DOE, others do not. Reread the contract or the CCAP as soon as it is signed, and seek legal advice in case of a dispute.
