Integrated function test
Fire alarm system, smoke and heat exhaust ventilation, ventilation and door hold-open systems must trigger together. For that you need all trades on site at the same time.
The building authority expects your report, and the operator often only reacts when the deadline for fixing defects runs out.
We buy firms with recognized certified inspection experts for fire protection, ventilation, smoke extraction, safety power supply and fire extinguishing systems. The requirement is at least two recognized people on the team.

Fire alarm system, smoke and heat exhaust ventilation, ventilation and door hold-open systems must trigger together. For that you need all trades on site at the same time.
The fire safety concept is outdated, and the as-built plans do not match the building. The inspection starts with paperwork.
The report lists defects with deadlines. The operator orders the repair late, and the re-inspection is postponed.
Every discipline needs a recognized certified inspection expert. If one drops out, special buildings are left without an inspector.

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 |
|---|---|---|
| Recognized certified inspection experts per discipline | Whether your firm can sign off inspections with legal certainty without the owner. | We look for at least two recognized people. |
| Special buildings in the current inspection cycle | How predictable your recurring inspections under the state PrüfVO are. | Good from 100 special buildings in the cycle. |
| Share of recurring inspections versus initial inspections | How much your business depends on new construction. | We look for a high recurring share. |
| Disciplines in-house | Whether you inspect a special building from a single source. | Good with several disciplines, such as ventilation, smoke and heat exhaust ventilation and safety power. |
| Open re-inspections after the defect deadline | How much capacity is tied up in repeat appointments. | We look at the development over three 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.
A model checks the fire safety concept, ventilation plans and system log against the PrüfVO and relevant standards.
Site visit notes and photos become the inspection report with a sorted defect catalog and suggested deadlines.
The system manages the three-year cycle for each special building and coordinates dates with operators and installers.
Recognition is personal per federal state, and function tests require the person on site.
You gain time for site visits, because the document check and the report are prepared in advance.

After the first call, these five documents are enough for an indicative offer. On request, we sign a non-disclosure agreement (NDA) first.
Enterprise value is not the payout. What reaches your account depends on four items:
If one of these points applies, the value drops:
We calculate your value in the first call using your numbers. We go through the four items openly with you, even if the result is below your expectations.
All market data and the regulatory timeline for testing and experts
No. It is personal and stays with you. In a share deal, the company remains in place. What matters is who is recognized after you.
Then we only buy with a path to requalification. An employee with five years of experience takes the exam with our support. You stay until then.
Inspection reports, defect lists, deadline tracking. The on-site inspection stays with the expert.

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.
