400 structural sub-units a year, inspector aged 58
The framework contract with the state road agency runs for three years. Who signs the inspection reports in five years?
A main inspection rarely fails because of the bridge. Usually the closure window, the under-bridge inspection unit or the time for the report is missing.
We buy engineering firms that inspect bridges, tunnels, retaining walls and noise barriers under DIN 1076. DIN 1076 requires a main inspection every 6 years and a simple inspection every 3 years, regardless of the construction cycle.

The framework contract with the state road agency runs for three years. Who signs the inspection reports in five years?
Half structural inspection, half structural design. Buyers only want one half. You are looking for someone who separates them cleanly.
The under-bridge inspection unit is booked, traffic management is in place, then it rains. The date slips by weeks.
The on-site inspection takes days, the report with damage descriptions and photos often much longer.
Every defect needs a rating for structural stability, traffic safety and durability. That takes experience and time at the desk.
A new inspector needs the VFIB course and years alongside an experienced colleague. That is your bottleneck.

We look at the numbers you use to run your business yourself. The right column shows our acquisition criterion.
| Metric | What it tells us | Our benchmark |
|---|---|---|
| Certified structural inspectors (VFIB) | How much inspection work you can deliver independently of the owner. | We look for at least two certified inspectors. |
| Remaining term of framework contracts | How secure the workload of the next inspection cycles is. | Good with more than two years remaining. |
| Inspection share of total revenue | How recurring your business is, compared with design and one-off reports. | We look for a high share of recurring inspections. |
| Structures per cycle by main and simple inspection | How well the six-year and three-year cycles are spread over the years. | Good with an even spread and no gap years. |
| Days from inspection to report submission | Where your capacity is actually tied up. | We look at how stable the value is over the years. |
We automate the desk work. Professional decisions and customer contact stay with your people.
This is GTP's assessment. We show it upfront so you can see what we will work with after the acquisition.
Image models detect cracks and spalling in drone footage and suggest damage classes to the inspector.
A language model drafts the report in SIB-Bauwerke format from the inspection database, with photos assigned.
Algorithms plan inspection routes by deadlines, closure times and locations and make good use of scaffolding time.
The main inspection requires hands-on examination on site, and the certified structural inspector is liable for every rating.
You keep the signature. We take the writing and sorting off your team.

All market data and the regulatory timeline for testing and experts
In a share deal, yes. An asset deal would trigger a new tender. That is why we structure inspection firms as share deals.
We value it separately and lower. A spin-off before the sale is often the better route. We discuss this openly.
Inspection reports from dictation and photos, suggested condition ratings, damage documentation. The inspector assesses and signs.
Response usually within 72 h, indicative offer in 2 to 4 weeks, recognition check as a separate step.
Testing services for portable equipment, fixed installations and machines.
Sell a certified inspection expert firmFire protection, ventilation, smoke extraction, safety power supply or fire extinguishing systems.
Sell a hazardous substance survey firmBuilding pollutants, asbestos surveys, contaminated sites and soil protection with recurring clients.
Additional testing servicesDrinking water and legionella testing, playground and sports facility inspection.

Your clients trust inspectors with a name and recognition. That is why we only buy if the team stays and the next generation already works in the business.
We first look at who will sign in five years. If that is only the owner, we tell you before any price discussion.
Acquisition profile, teaser metrics and our commitments for all 24 segments are on a separate page. We only approach your client through you.
A 30-minute call is enough to know whether we fit. Afterwards you get a written assessment with reasons.
