- 3Fixed prices create full cost control with no hidden fees.
Tuesday, 7:30 a.m., a construction yard near Hamburg-Harburg. A CAT 320 tracked excavator is ready for its residual-value appointment. The owner plans to sell the machine in order to modernize the fleet. In the construction industry, the sale price is often decided by nuances: the condition of the hydraulics, the remaining tread depth of the tracks, and complete documentation of operating hours. A DIAVAG appraiser arrives on time to independently value the asset. Instead of the effort of transporting the heavy machine to a testing facility, the appraisal takes place directly on site. This process saves time and delivers the legal certainty needed for the upcoming sales negotiations.
The Relevance of an Independent Valuation in the Used Equipment Market
The market for used construction and agricultural machinery is complex and characterized by high investment sums. A valuation report prior to sale serves as an objective basis for negotiation. Without such a document, price expectations are often based on subjective assessments or imprecise list prices that disregard the machine's individual condition. An independent DIAVAG appraiser evaluates the asset neutrally. Since DIAVAG does not sell vehicles, does not broker insurance and does not carry out repairs, independence is preserved. This is a decisive advantage over dealer valuations, which are often driven by self-interest.
A legally sound report protects the seller from later recourse claims and gives the buyer the assurance of acquiring a technically inspected machine. Especially with high-value assets such as excavators, wheel loaders or combine harvesters, undetected defects in the hydraulics or drivetrain can lead to massive follow-up costs. The DIAVAG report documents the actual condition precisely, thereby creating a basis of trust that significantly speeds up the sales process. Compliance with BVSK standards ensures that the document is also recognized for financing or insurance matters.
Mobile Service: Efficiency through On-Site Inspection
A key differentiator for DIAVAG is mobility. Construction machinery and agricultural equipment are difficult to transport due to their size and weight. Transport to a stationary testing facility such as TÜV or DEKRA causes high costs and logistical effort. DIAVAG solves this problem by having the appraiser come directly to the asset's location, whether that's the construction yard, the field or the port. This mobile service is available within 24 hours in the regions of Hamburg, Berlin and Munich.
On site, the appraiser carries out a standardized workflow specifically tailored to the requirements of heavy machinery. On-site processing time is typically under 15 minutes, as processes are made efficient through calibrated hardware and a specialized software solution. Despite the short time on site, the depth of data is high. All relevant parameters are captured digitally and transferred directly into the system. This makes it possible to deliver the finished PDF report on the same day, which is a decisive factor especially for time-critical transactions.
Fixed-Price Model: Transparency without Hidden Costs
Billing by the hour or by the value of the item is widespread in the appraisal industry. For the customer, this often leads to unpredictable costs. DIAVAG relies here on a transparent fixed-price model. For the Private Standard, which covers many common construction and agricultural machines, the valuation is carried out at a fixed price. High-value assets or machines that require deeper technical analysis are appraised under the Premium tariff. This price includes all call-out costs within the regions as well as preparation of the BVSK-compliant report.
For commercial customers, such as construction machinery dealers or fleet operators who require a high volume of valuations, DIAVAG offers individual terms. An API connection to existing Dealer Management Systems (DMS) is also possible here, to seamlessly integrate the reports into the company's digital processes. This calculation certainty allows companies to precisely plan the costs of inventory valuation. Book a demo to learn about our pricing models for fleet operators.
Technical Inspection Scope and Hardware Deployment
The quality of a valuation report depends on the precision of the data collection. DIAVAG appraisers use a specially assembled hardware case that contains calibrated measuring devices for various asset classes. For construction machinery, the focus is on mechanical integrity and electronics. Where the machine has a suitable interface, an OBD2 scanner (often the SAE J1939 standard for heavy machinery) is used to read out fault memory and check real-time parameters of the engine and exhaust after-treatment.
In addition, coating-thickness gauges are used to reveal any repainting that could indicate hidden accident damage or corrosion repairs. Tire tread depth or the wear condition of track undercarriages is documented, as is the condition of hydraulic cylinders and lines. A key component is the standardized photo documentation. This covers not only the overall view but also detailed shots of nameplates, operating-hour counters and critical wear points. This data forms the basis for the analysis, with experienced senior inspectors steering and validating the final assessment; AI-driven efficiency meets human expertise.
Legal Certainty and Standards: BVSK and ISO/IEC 17020
A report is only worth as much as its acceptance by third parties. DIAVAG meets the highest requirements for qualification and independence. All appraisers work according to the guidelines of the BVSK (Federal Association of Independent Freelance Motor Vehicle Appraisers). In addition, the inspection service is organized under ISO/IEC 17020 Type A, representing the highest level of independence. This means DIAVAG maintains no economic ties whatsoever with the trade or repair of machinery.
This independence is especially important when the report is to be used in legal contexts, such as inheritance cases, divorces or insurance claims. Such a report also provides a solid basis under the JVEG (Judicial Remuneration and Compensation Act). For maximum tamper-resistance, DIAVAG optionally offers a notarial hash on the Polygon blockchain. This makes the machine's condition at the time of inspection immutably documented. For complex legal questions, however, DIAVAG always recommends consulting a specialized lawyer or notary.
Future-Proofing: EU Machinery Regulation and Battery Passport
Regulatory requirements for construction and agricultural machinery are steadily rising. An important date is January 20, 2027, when the new EU Machinery Regulation 2023/1230 becomes mandatory. This regulation imposes higher requirements on the safety and digital documentation of machines. DIAVAG is already preparing its reports for these upcoming standards today, to guarantee customers long-term admissibility of their documents.
Another trend is the electrification of construction machinery, such as compact electric excavators or wheel loaders. This is where DIAVAG's Premium Battery Test comes into play. While conventional testing organizations often only offer a basic diagnosis, DIAVAG provides detailed data on State of Health (SoH), cell balance and the actual capacity of the high-voltage battery. Analogous to the upcoming EU Battery Passport (February 2027), this is a key factor for the resale value of electrically powered assets. Anyone who invests in a report today safeguards themselves against rapid devaluation caused by technological change.
Comparison of Valuation Approaches
To understand DIAVAG's positioning, a comparison with other market participants is worthwhile. While traditional testing organizations focus on the periodic technical inspection (HU), DIAVAG focuses on market-based valuation and technical condition reporting across 30+ industry verticals.
| Feature | DIAVAG | HU Organizations (TÜV/DEKRA) | Online Estimate Portals |
|---|---|---|---|
| Mobile service | Yes (yard/construction site) | Mostly stationary | No (data only) |
| Asset classes | 30+ industries (incl. 9 DD workstreams) | Focus on cars/trucks | Cars only |
| Fixed price | Fixed price | Based on effort/fee | Often free/imprecise |
| Battery test | Premium (SoH/cells) | Basic diagnosis | None |
| Independence | Complete (Type A) | Partial (testing monopoly) | Often tied to purchase |
This comparison shows that DIAVAG fills a gap between pure technical testing and interest-driven vehicle trading. In particular, the combination of mobility and fixed pricing makes the service attractive to players in the construction industry.
