Contracts, change orders and construction disputes — checked before they get expensive

A subcontractor fails to finish, a second contractor has to complete the work, and suddenly it's about grace periods, substitute performance and extra cost (German Civil Code §§ 636, 637, 280, 281, or § 4(7)/§ 8(3) VOB/B, from the client's perspective against the sub). That exact case was the reason this platform built out its construction-law substance in the first place.
Instead of single documents, you can upload an entire matter together: contracts, bills of quantities (spreadsheets included), invoices and the full email correspondence. From that, a timeline, a relationship graph of everyone involved and an evidence overview emerge — every point jumps straight to the passage in the original document.
And before you send out your own quote with terms and conditions, a form check runs automatically — open placeholders, a missing signature, a missing date, forgotten attachment references. This does not replace a construction lawyer: we prepare the matter so the handover to one is structured, not a loose stack of files.
What the platform does for construction companies
Four building blocks, each for a concrete construction dispute.
Subcontractor doesn't finish
Substitute performance and grace period under §§ 636, 637, 280, 281 BGB — including the VOB/B branch (§ 4(7) / § 13(5) / § 8(3)) if your contract includes it.
A change order is disputed
Enforce additional payment under §§ 650b, 650c BGB or § 2 VOB/B — with default-interest calculation for your own claim.
A whole matter, not one document
Evaluate contracts, bills of quantities, invoices and email correspondence together: a timeline, participants, contradictions, and an evidence overview with source references.
Check your own quote before sending it
A deterministic form check runs automatically — open placeholders, a missing signature, a missing date, forgotten attachment references — at no extra cost.
- Legal questions without a document
- Chat with follow-ups in the matter
- Analysis, exports, lawyer handover
- Writing assistant & templates
A subcontractor who doesn't finish is rarely the only problem in the matter — usually a change order, an invoice and correspondence hang directly off it.
One matter, not a stack of documents
What changes when an entire matter is reviewed
Both sides look at the same matter — only the preparation differs.
Every document on its own
- Read contracts, bills of quantities, invoices and emails one by one and piece them together in your head
- Search for contradictions between documents by hand
- Only skim your own quote before sending it
Everything evaluated together
- A timeline and a relationship graph of everyone involved, built from every document you uploaded
- Contradictions shown as a suggestion to confirm, with the source passage in the original
- A form check of your own quote runs automatically at no extra cost
Reviewing an entire matter is a paid add-on from the Pro plan; the form check runs automatically on every document analysis.
