04 — Collaboration & consortia
One preparer to
nine companies.
Bids are won by people who don't sit in the same building — a lead contractor, specialist subcontractors, a partner two countries away. Steinlog puts them in the same bid without flattening the boundaries that keep it safe.

No more emailing versions around and merging by hand. One live bid, edited together, every change attributed — and no doubt about which file is current.
Piling will be executed as driven precast in accordance with addendum №3JV, sequenced to minimise disruption to the adjacent carriageway.
Temporary works design by the appointed structural engineer, reviewed against §2.4MB.

Answer library
Your best answers,
one search away.
Certificates, references, CVs, method statements — the material you reuse on every bid, versioned and searchable. Visible to your team only. It is never shared with consortium partners, no matter how the bid is assembled.
Consortium data rooms
Partners see the bid.
Never your library.
Partner accounts are scoped to a single project and see only the documents you have included in the bid — never your answer library, never another project. Everyone works from the same current version, and every partner access is on the record.

The combinatie itself
Who is in the bid,
and who is blocking it.
Before anyone can submit, the combinatie has to exist on paper: penvoerder and combinant, each with its KVK registration and its own required artefacts. Steinlog holds that register inside the bid and says plainly what is still in the way.

A live TenderNed tender in the demo bid room; the two firms are fictional. The banner is the gate talking — no per-combinant requirements are seeded yet, so the combinatie is flagged as blocking submission rather than quietly passing.
