Buying a construction company in Austria: projects, trade law and liability risks: this article focuses on ongoing construction projects, trade-law capability and warranty risks, not on a generic M&A checklist.
Do not value a construction company only by backlog. Check each project, retention, variation claim, defect notice, site manager and subcontractor chain before signing.
The contract should translate those points into conditions to completion, warranties, indemnities and price mechanics.

Contract mechanics for ongoing construction projects, trade-law capability and warranty risks
Contract mechanics for ongoing construction projects, trade-law capability and warranty risks
The purchase agreement must convert the review into concrete mechanics. Critical points become conditions, known risks become indemnities or price adjustments, and uncertain facts become warranties.
This is where the transaction differs from a generic share or asset deal. The agreement should name the specific risk, the evidence required and the consequence if the point is not solved.
Signing, closing and post-closing control
Signing, closing and post-closing control
Timing matters because consents, evidence and handover steps often decide whether the buyer can operate on day one after closing.
A closing list should state who delivers what, when, in which form and what happens if a document or consent is missing.
Checkpoints
Projects, trade capability and defect risk before signing
This overview shows the deal-specific issues that should not disappear into general clauses.
| Point | Why it matters | Contract consequence |
|---|---|---|
| Perimeter Perimeter | project list, trade licence and site liability define the economic object of the deal. | Attach a specific schedule and warrant its completeness. |
| Consent/evidence Consent/evidence | The buyer needs proof before completion. | Use conditions to completion and closing deliverables. |
| Legacy risk Legacy risk | Known issues should stay economically with the right party. | Use indemnity, escrow or price adjustment where appropriate. |
The overview does not replace case-specific review, but it shows the typical risk fields.
