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.

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.

The combinatie, registered demo project · live tender data
The combinatie panel: penvoerder Van Dijk Bouw and combinant Iv Installatietechniek registered with their KVK numbers and addresses, each with its own required-artefact count, under a banner naming the combinatie-eisen that block submission.

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.
