Tuesday, 7:30 a.m., a construction yard near Hamburg-Harburg. A CAT 320 crawler excavator stands ready for assessment. The owner needs a solid market value for the company's upcoming inventory valuation. In such moments, having an appraiser nearby is crucial, yet often hard to find. DIAVAG solves this problem with a mobile concept: the appraiser comes directly to the asset, whether at the construction site, the operations yard, or the field. Using standardized hardware and a BVSK-compliant workflow, the condition is objectively recorded. This saves time and high logistics costs for low-loader transport to a stationary inspection site.
The Relevance of Mobile Reports for Nearby Construction Machinery
The search for a construction machinery appraiser nearby often fails due to the specialization of local vehicle appraisers. While many offices focus on car accident damage, excavators, wheel loaders, or combine harvesters require specific expertise and mobile availability. A key advantage of DIAVAG's mobile service is the elimination of transport routes. Transporting heavy construction machinery to an inspection center by low-loader incurs costs that often exceed the value of the report itself. The mobile approach eliminates these logistics costs entirely.
DIAVAG operates in regions such as Hamburg, Berlin, and Munich and guarantees appointments within 24 hours. The appraiser appears directly at the machine's location. This is especially important during downtime or on active construction sites, to disrupt operations as little as possible. Proximity is thus defined by the service provider's mobility, not by a fixed office location. For contractors and farmers, this means significant time savings and planning security when valuing their machinery fleet.
Standardized Inspection Workflow and Hardware Use
A legally sound valuation report is based on methodical data collection. On-site, the DIAVAG appraiser uses a standardized workflow supported by calibrated hardware. This includes the use of OBD2 scanners or specific interfaces such as SAE J1939, provided the machine has corresponding electronics. Fault memories are read out and operating hours verified to rule out manipulation of the meter reading. A digital multimeter checks the electrical systems, while coating-thickness gauges provide information about repainting or concealed structural repairs on the boom or frame.
Visual documentation follows a strict protocol. Every component, from the hydraulic pump to the undercarriage to the attachments, is photographically captured. These photos are part of the BVSK-compliant PDF report. The condition of tires or tracks is precisely documented using tread-depth gauges. This data-driven approach differs significantly from subjective estimates. The result is an objective finding that reflects the machine's actual state of wear and operational fitness. On-site processing time is usually under 15 minutes, underscoring the efficiency of the system.
Legal Certainty Through BVSK and ISO/IEC 17020 Type A
The usability of a report depends heavily on the qualification and independence of its creator. DIAVAG appraisers work according to the standards of the German Federal Association of Independent Automotive Appraisers (BVSK). In addition, the inspection body is eligible for accreditation under ISO/IEC 17020 Type A, representing the highest level of independence. This is particularly relevant when the report is needed for legal disputes, inheritance matters, or divorce proceedings. In such cases, the report serves as an objective basis for lawyers and notaries.
In insurance cases or when determining replacement value, BVSK compliance offers high acceptance among insurers. The report is finally signed by a senior inspector, representing additional quality assurance. If the report is to be used for judicial purposes under the Judicial Remuneration and Compensation Act (JVEG), DIAVAG provides the necessary technical depth. However, it is important to emphasize that DIAVAG does not provide legal advice. For legal questions, customers should always consult a qualified lawyer or notary.
Transparent Flat Rates for Construction and Agricultural Machinery
A common problem when commissioning appraisers is unpredictable costs from hourly billing and travel fees. DIAVAG relies on a transparent flat-rate model here. For standard construction machinery, the price is auf Anfrage. For high-value assets or complex machines requiring deeper inspection, the premium price is auf Anfrage. These prices apply within the regions with no hidden additional costs. This allows companies to calculate the costs of inventory valuation precisely.
| Service | Private Standard | Premium / High-Value |
|---|---|---|
| Price | auf Anfrage | auf Anfrage |
| Travel (region) | Included | Included |
| BVSK Compliance | Yes | Yes |
| Appointment Guarantee | 24 hours | 24 hours |
| PDF Delivery | Same day | Same day |
This model contrasts with traditional appraisal offices, which often bill based on the object's value or on an hourly basis. For dealers or fleet operators requiring a volume of more than 50 reports per month, DIAVAG offers individual terms. An API connection to existing Dealer Management Systems (DMS) is also possible here, fully digitizing the valuation process.
Impact of the EU Machinery Regulation 2023/1230
Regulatory requirements for construction machinery are steadily increasing. The new EU Machinery Regulation 2023/1230, mandatory from January 20, 2027, sets new standards for the safety and documentation of machines. A professional valuation report already takes into account safety-relevant aspects that could be decisive for future operating permits and resale value. As part of the inspection, appraisers check whether the machine meets current safety standards and whether all necessary documentation is available.
For owners, this means that a report not only quantifies financial value but also represents an assessment of compliance. This is particularly important for cross-border trade within the EU. Buyers increasingly value proof that machines meet European guidelines. A DIAVAG report provides the necessary data basis for this and documents the technical condition at the time of inspection. This protects sellers against later recourse claims regarding obvious defects or missing safety devices.
Asset Classes: From Excavators to Home Battery Storage
DIAVAG covers a total of seven asset classes, setting the company apart from classic passenger car inspection organizations such as TÜV or DEKRA. In the field of construction and agricultural machinery, the range includes crawler and wheeled excavators, wheel loaders, telehandlers, as well as tractors and combine harvesters from renowned manufacturers such as Fendt, John Deere, or Liebherr. Each of these machine classes has specific wear points that are taken into account in the inspection workflow. For agricultural machinery, the focus is often on power take-off performance and transmission condition, while for construction machinery, hydraulic pressures and play in pin connections are critical.
In addition to heavy mechanics, the assessment of electrical components is becoming increasingly important. For e-construction machinery or stationary home storage systems, often operated in combination with agricultural photovoltaic systems, DIAVAG offers the Premium Battery Test. This test determines the state of health (SoH) of the batteries, cell balance, and actual capacity. Since the battery is often the most valuable single item in electrically powered assets, this precise diagnostic is essential for a market-appropriate valuation. TÜV and DEKRA often only offer basic diagnostics in this area, which are insufficient for a detailed valuation.
Independence as a Core Value of the DIAVAG Philosophy
A decisive feature of DIAVAG is its strict independence. The company does not sell vehicles, does not broker insurance, and does not carry out repairs. This neutrality is the prerequisite for creating objective reports. Unlike vehicle-purchase platforms, whose goal is to buy at the lowest possible price, DIAVAG has no vested interest in the outcome of the valuation. The report reflects the real market value based on technical facts and current market data.
This independence is a structural advantage over workshops, which often create reports with an eye toward subsequent repair orders. For customers, commissioning DIAVAG means receiving a document that holds up before third parties. Whether toward the tax office in a business transfer or toward a potential buyer: the appraiser's neutrality is the strongest argument for the validity of the price. As a brand of CITO GmbH, DIAVAG stands for professional standards and a transparent process chain from appointment booking to the finished PDF report.
Digital Security and Blockchain Verification
In an increasingly digital world, protection against document forgery is essential. DIAVAG uses modern technology to ensure the integrity of its reports. Every PDF report created can optionally be secured with a notarial hash on the Polygon blockchain. This digital fingerprint makes the document tamper-proof. A third party can verify at any time whether the report at hand is in its original state or whether values or photos have been subsequently altered. This significantly increases trust in transactions between unfamiliar parties.
Data is stored in a GDPR-compliant manner on servers within the European Union. Customers receive their report digitally the same day as the inspection. This massively speeds up sales processes or the handling of insurance claims. While traditional appraisers often need several days to complete their work, DIAVAG's digitized workflow enables immediate availability of results. The combination of human expertise from the senior inspector and digital process speed sets new standards in the asset valuation industry.
Solutions for Dealers, Fleets, and Appraisers
DIAVAG serves not only private customers but also offers specialized solutions for the B2B sector. Dealerships, construction machinery dealers, and fleet operators benefit from standardized valuations of their inventory. From a volume of 50 reports per month, individual terms are agreed. Integration into existing Dealer Management Systems (DMS) via API enables seamless incorporation of condition reports into sales portals. This significantly increases efficiency in the purchase and sale of used machinery.
For self-employed appraisers looking to expand their portfolio, DIAVAG offers a partner model. The hardware case, including the necessary software licenses, is available at a list price of auf Anfrage. This allows appraisers to apply the standardized DIAVAG workflow in their region and become part of a nationwide network. Through uniform hardware and central quality assurance by senior inspectors, a consistently high standard of reports is guaranteed, regardless of where in Germany the inspection takes place. This supports the nationwide rollout planned for 2026.
