It really pays off to pay attention to the details when creating VOB revision documents – it will pay off in the long run.Let’s get to the point: What is really included in the VOB revision documents?

What exactly are revision documents?

Simply put, revision documents document what a building actually looks like after its completion. They include all changes and adjustments made during construction compared to the original planning. This precise documentation is the foundation for appropriate maintenance, repairs, and any future renovations or expansions. If these complete and correct VOB revision documents are missing or incomplete, operators or later trades often find themselves in trouble when it comes to understanding and effectively managing the installed systems and equipment. Importantly, the documents must be prepared so that everyone can understand and operate the system. Therefore, the creation of these VOB revision documents is an integral part of the owed construction performance.

• Definition: They document the actual ‘As-Built’ condition of the building after completion.
• Foundation: Essential for operation, maintenance, repairs, and future renovations.
• Legal framework: Obligation often arises from VOB/B and VOB/C; clear contracts are crucial.
• Typical content: Include revised plans, technical data, instructions, and test protocols.

Understanding legal and contractual foundations

While the German Civil Code (BGB) doesn’t explicitly address revision documents, the obligation to create them often arises from contractual agreements – especially when VOB/B (Regulations on Tendering and Contracting for Construction Services Part B) comes into play. VOB/B, in turn, refers to VOB/C (General Technical Contractual Conditions for Construction Services – ATV). And that’s where many trades require the delivery of revision documents as ancillary services. Clear contractual agreements in the service description are crucial, to define the exact scope, level of detail, and format of the VOB revision documents in order to avoid later inconsistencies. Without precise agreements, there is a risk that the client does not receive the documents necessary for proper operation. Therefore, careful creation of revision documents is essential.

Typical contents of revision documents

What should all be included in the VOB revision documents? That varies widely and depends on the respective trade. However, the core components usually include:

• Revised drawings and plans: These are as-built plans that show how the work was actually carried out (e.g., where pipes are located, what installations exist).
• Technical specifications and data sheets: Here you find detailed information about the materials, components, and systems used (important, e.g., for VOB revision documents for electrical or TGA). Operating and maintenance instructions:
• Bedienungs- und Wartungsanleitungen: The manufacturer’s instructions for proper operation and maintenance.
• Test protocols and certificates: Certificates for conducted tests, startups, and inspections.
• Material information and spare parts lists: Details about manufacturers and type designations, so spare parts can be easily procured.

These documents, as part of the VOB revision documents, must cover all relevant trades, from the structural work to the technical building equipment (TGA) to the finishing, such as for revision documents for drywall construction or revision documents for tile layers.Norm jungle VOB/C & DIN: How to keep track of revision documents

VOB/C (ATV) as a normative basis

The Regulations on Tendering and Contracting for Construction Services Part C (VOB/C) – the General Technical Contractual Conditions for Construction Services (ATV) – are our most important guide here. These ATVs are published simultaneously as DIN standards and establish which documents must be provided as part of the service for the individual trades. VOB/C thus serves as the central normative basis for the obligation to create VOB revision documents. Since the latest VOB updates, especially with the VOB 2019, it has been defined even more precisely what must be included in the VOB revision documents to ensure greater transparency and quality. As a construction company, you cannot avoid being familiar with and applying the current versions of the relevant ATVs in order to provide compliant documents.

Important DIN standards at a glance

But it’s not just VOB/C that matters; there are also several specific DIN standards that formulate detailed requirements for specific trades. VOB revision documents Among the most important are:

• DIN 18382: Electrical, safety, and information technology systems (relevant for VOB revision documents for electrical systems). This standard has been revised and now provides detailed instructions for the execution of construction and electrical works – important for the service description and the corresponding documents.
• DIN 18381: Gas, water, and drainage systems within buildings.
• DIN 18379: Room air technology systems (relevant for revision documents for TGA).
• DIN EN 61082-1 (VDE 0040-1): Creation of documents in electrical engineering, especially for electrical schematics.
• DIN VDE 0100-600: Requirements for the installation of low-voltage installations – Part 6: Tests.

Knowing and complying with these DIN revision document standards is incredibly important to ensure the work is accepted. A good document management software for construction can be a great help here.

VDI Guideline 3805 as a guideline

The VDI Guideline 3805 is also a real help, especially when creating VOB revision documents for technical building equipment (TGA). It makes the requirements for the content and type of planning, execution, and revision documents more concrete. This guideline is based on frameworks such as HOAI (Fee Structure for Architects and Engineers) and helps to establish a structured and complete documentation. The VDI 3805 is particularly useful, to manage the often complex TGA documentation and ensure all important aspects for operation and maintenance are VOB revision documents taken into account. It is considered a recognized standard of technology and should be observed when creating revision documents for TGA .Plan proactively: Why revision and execution planning are your recipe for success

Advantages of proactive revision planning

Those who plan proactively save themselves trouble and extra costs later on during the VOB revision documents – it’s that simple. So don’t start collecting only at the end of the project, but plan revision work objectively, timely, and with sufficient personnel from the start. This means systematically capturing all relevant project systems and processes from the outset. Documenting continuously during the construction phase ensures no information is lost and that the VOB revision documents accurately reflects the current status. This approach minimizes the effort required for subsequent creation and significantly reduces the risk of errors. A construction documentation app can greatly simplify this process.

1. Early planning of revision work saves costs and avoids issues.
2. Continuous documentation during the construction phase ensures information integrity.
3. A detailed execution plan is the basis for complete revision documents.
4. The VOB 2019 tightens the requirements for coordination and submission of documents.

Execution planning as a solid foundation

Good execution planning is essential for top revision planning and therefore for complete VOB revision documents. Our advice: Every planned and executed service should be carefully documented in every project phase. This includes all changes and adjustments that arise during the construction process. A detailed execution plan that is always up-to-date is essential to avoid complaints and conflicts regarding these documents. The quality of your execution plan directly impacts the quality and completeness of the final VOB revision documents. Utilizing a cloud-based construction documentation helps you keep all data centralized and up-to-date.

VOB 2019 updates and their impacts

With the VOB 2019, the requirements for documentation have become more precise. It includes a detailed list of documents required for planning, execution, and maintenance. A crucial new requirement is that contractors must now coordinate and submit assembly and work plans according to VDI 6026 Sheet 1 with the client before execution. Furthermore, the contractor must submit detailed VOB revision documents for review to the client before acceptance. These tightening measures aim to increase transparency and reduce ambiguities regarding contractually defined and additionally compensated services. This improves quality assurance, especially for complex trades like electrical work, and ensures that the VOB revision documents meet current standards.Beware of pitfalls! How to avoid costly mistakes with incomplete VOB revision documents

Legal pitfalls and their consequences

If VOB revision documents are missing or incomplete, it can lead to serious legal trouble. Courts agree, as evidenced by the ruling: This constitutes a defect in the construction performance. This means the client may withhold part of the final payment (right of retention). And the withholding can easily amount to double the costs of remediation, i.e., of redoing the documents. In the worst case, the client may even refuse acceptance, if the missing VOB revision documents represent a significant defect – especially with complex technical systems. This can lead to considerable delays and financial losses for the executing company. A careful change and defect management according to VOB B is worth its weight in gold here.

• Missing documents are considered a defect, which can lead to payment withholdings.
• The client can refuse acceptance in case of significant defects.
• Substantial costs for redoing documents and liability risks for planners can arise.
• Practical problems such as increased maintenance difficulties, higher operating costs, and user errors are the result.

Don’t underestimate financial impacts

Do not underestimate the costs that can arise from inadequate VOB revision documents . Besides the money that is initially withheld, there may be substantial costs for the subsequent creation of the documents may incur. If the client has to hire a third party to reconstruct the data, it often ends up being significantly more expensive than the initial creation. Additionally, the TGA planner (technical building equipment specialist) may be held liable for advisory faults if he fails to adequately inform the client about the necessity and scope of the VOB revision documents resulting in costs for remaking them. Therefore, investing in early and thorough documentation definitely pays off to avoid these financial risks associated with these documents.

Practical problems in operation and maintenance

But it’s not just legally and financially; without adequate VOB revision documents real problems will arise later in operations. Increased maintenance and repair difficulties are a common result, as essential information about the installed components, their location, or specific settings is missing. This can lead to longer downtimes and higher operating costs. Moreover, accurate record documents are essential for planned renovations or expansions. If these are missing, often elaborate investigations must be conducted to establish the actual condition. Last but not least, the risk of user error increases if the personnel do not have clear and understandable instructions and plans as part of the VOB revision documents available. A correct acceptance according to VOB requires complete documents.Documentation pros at work: Our best practices for top VOB revision documents

Contractual clarity as a foundation

To ensure that everything runs smoothly later on, you must set the course right at the contract signing. It is absolutely essential to clearly and in detail specify in the construction contract or service description which revision documents are required VOB revision documents später rund läuft, müssen Sie schon bei Vertragsabschluss die Weichen stellen. Es ist absolut unerlässlich, . This includes the exact scope, the desired format (digital and/or paper), the level of detail, and binding delivery dates – ideally before the . When it is clearly defined what is meant by ‘complete. Das umfasst den genauen Umfang, das gewünschte Format (digital und/oder Papier), den Detaillierungsgrad und verbindliche Liefertermine – idealerweise vor der . Wenn klar definiert ist, was unter “vollständigen VOB revision documents‘ this helps prevent later discussions and disputes. Incorporating sample documentations or references to specific standards and guidelines can be very helpful here. A clear contractual arrangement protects both parties and ensures that expectations regarding these documents are transparent from the start.

Utilize checklists and sample documentations

Our tip for complete and correctly structured VOB revision documents: Use checklists and sample documentations. Checklists help systematically capture all necessary documents and ensure no point is overlooked. Trade-specific checklists based on the requirements of VOB/C and relevant DIN standards are particularly effective. Sample documentations provide a clear structure for how the documents should be organized and which content should be presented in which form. This not only facilitates the creation but also the later usage and review of the documents. Adhering to established standards, such as those available for revision documents for electrical work , can significantly improve the quality of the VOB revision documents .

Digital solutions for efficiency and transparency

Digitalization is a real booster for optimizing the creation and management of VOB revision documents. The use of Digital Document Management Systems (DMS) allows for centralized, structured storage and quick access to all relevant documents. The integration of Building Information Modeling (BIM) takes it a step further by creating ‘As-Built’ models that digitally represent the actual construction condition and increasingly replace traditional VOB revision documents . Also, linking with CAFM systems (Computer-Aided Facility Management) is crucial for later operations. Modern tools like a daily construction report software or a digital defect management system also contribute to the comprehensive documentation vital for this documentation. Data collection through 3D scanning during important construction phases can further enhance the accuracy of the record documentation.

Formal requirements and structuring

Don’t forget the formal aspects when submitting your VOB revision documents . Often specific requirements are placed on the outer form, such as delivering in black DIN A4 binders with precise labeling (company logo, performance phase, property, binder identifier, currency). A function-based categorization within the folders, both physically and digitally, is crucial for clarity. Equipment maps that are directly attached to the respective system provide a quick reference for important technical data, maintenance instructions, and spare parts. These formal requirements for the VOB revision documents serve to standardize and significantly ease handling and archiving.A glimpse into the future: What to expect from VOB revision documents

Digitalization as a driving force for change

Digitalization is completely transforming the management of VOB revision documents . Digital formats make the creation, management, and use of documentation much more efficient. Central storage in the cloud, real-time updates, and improved collaboration among all project participants are just a few of the advantages. Instead of mountains of paper binders, there are intelligent database systems and platforms that allow for quick and location-independent access to the needed information in these documents. The result? Better data quality, fewer errors, and considerable time savings throughout the entire lifecycle of a building. It is important that everyone accepts digital processes to fully leverage the potentials and future-proof the creation of these documents.

Technological innovations on the rise

But it’s not only general digitalization – specific technological advancements are also impacting the future of VOB revision documents . Augmented Reality (AR) and Virtual Reality (VR) can be used, for example, for intuitive visualizations of existing data and maintenance instructions. Artificial Intelligence (AI) can assist in the automatic verification of document completeness and compliance or help analyze operational data. Blockchain technology promises tamper-proof documentation of changes and approvals. These technologies have the potential to further increase efficiency, accuracy, and security in handling these documents. Additionally, the aspect of sustainability is gaining more focus, with digital VOB revision documents helping to reduce paper consumption.

BIM and CAFM: Integration as a goal

Building Information Modeling (BIM) is becoming increasingly important in the creation of VOB revision documents. The ‘As-Built’ model, which digitally represents the actual end state of the building, is increasingly becoming the central source of information. The seamless integration of this BIM data into CAFM systems (Computer-Aided Facility Management) is crucial for efficient building operations. This requires early planning of how and which data from the BIM model will be transferred to the CAFM system. Contractual agreements must clearly define the requirements for the ‘As-Built’ model to ensure that all relevant information for operation is included in the documents or in the digital model. Early definition of interfaces and responsibilities is critical to success.

Key benefits of careful preparation of VOB revision documents

If you create and manage your VOB revision documents diligently, all project participants benefit:

• Legal certainty and risk minimization: Complete documents serve as proof that you worked properly and minimize the risk of disputes and financial delays. They are essential for the acceptance according to VOB.
• Efficient operation and maintenance: Accurate record data enables optimized maintenance, reduces downtimes, and ultimately lowers operating costs in the long run.
• Foundation for future projects: Detailed VOB revision documents facilitate renovations, expansions, or restorations, as the actual condition is clearly documented.
• Transparency and traceability: A comprehensive documentation creates transparency about the services provided and the decisions made throughout the construction process. This is also important for the change management process.

Time to get to work: Your checklist for perfect VOB revision documents

Preparation before construction execution

Good preparation is a vital step, even with the VOB revision documents. Review and supplement contractual agreements regarding the scope, format, and submission deadlines of the documentation. Create detailed, trade-specific checklists for all required documents based on VOB/C, DIN standards, and your specific project requirements. Clearly define the responsibilities for creation, review, and approval of individual documents of these files. Clarify early which software or systems will be used for documentation to ensure consistent data handling. A good creation of revision documents documentation begins with solid planning.

Documentation during construction execution

The cornerstone for creating VOB revision documents is continuous documentation during construction execution. All changes and adjustments compared to the original planning must be continuously and accurately documented. Utilize digital tools like a construction documentation app for photos, videos, and notes directly from the construction site. Create and collect all relevant protocols in a timely manner, such as pressure test protocols, commissioning protocols, and briefing protocols. Ensure that all documents reflect the actual execution status and are traceable. The quality of your ongoing documentation significantly determines the quality of the final documents.

Completion and handover after construction execution

Once the construction work is completed, it’s time to compile and perform the final check of the VOB revision documents. Ensure that all documents are complete according to the checklists and contractual agreements. Pay attention to the compliance with formal requirements, such as the correct folder structure, labeling, and required format (e.g., paper and/or digital). Create digital copies of all documents and ensure secure archiving. The handover to the client should be documented. A careful final inspection prevents complaints and ensures smooth acceptance. Remember that the timely submission of these documents is often a prerequisite for final payment.

Important documents for your VOB revision documents

To give you an idea of which documents are typically part of the VOB revision documents , we have compiled a list for you:

• Plans and drawings: As-built plans (floor plans, sections, views), detail drawings, pipeline diagrams, circuit diagrams (especially for VOB revision documents for electrical systems).
• Technical documentation: Data sheets for the products used, performance descriptions, declarations of conformity, certificates.
• Bedienungs- und Wartungsanleitungen: Manufacturer’s instructions for all technical systems and devices.
