Dalux

BIM viewing, snagging and field quality control for construction and facilities teams

As of 31 August 2026, Dalux is free to use. A Danish construction field platform built around a 3D model viewer that runs on an ordinary phone. Softwr lists it under Construction. Dalux is available on Web, iOS, Android, Windows.

Overview

What Dalux does

Dalux is a construction collaboration platform from Copenhagen covering document control (Dalux Box), site quality and safety (Dalux Field), linear infrastructure work (InfraField), handover, tendering and post-handover facilities management (Dalux FM). The common thread is a BIM viewer that renders federated multi-discipline IFC models on mobile hardware, so a site engineer can stand in a room, point a phone at it and raise a snag against the model object rather than against a pin on a flat PDF. The distinguishing commercial move is that BIM Viewer and Field Basic are free permanently, and free users can be invited to a project without limit. That inverts the usual construction software economics, where every subcontractor seat is billed. A main contractor buys the paid modules and pulls its whole supply chain onto the platform at no cost to them, which removes the objection that normally stops site adoption dead. Rivals that charge per invited user often end up with the trades still working from printed drawings, so the free tier is a distribution strategy rather than a discount. Buyers are Northern European main contractors, engineering consultancies and public asset owners, concentrated in Denmark, Norway, Sweden, Germany and increasingly the UK. The trade-off is scope and ecosystem. Dalux is not a commercial or financial management system: there is no estimating, no payment applications, no cost control and no subcontractor procurement, so it sits alongside your finance stack rather than replacing it. Its integration list is far shorter than the American platforms, and it publishes no price for anything paid.

What people use it for

  • A Nordic main contractor wants every subcontractor raising and closing snags in one system without paying a seat fee for each trade, so the free Field Basic tier carries the supply chain.
  • An engineering consultancy needs site staff to interrogate a federated model on a phone in a basement with no signal, where a browser-based viewer would be useless.
  • A public asset owner wants the as-built model and asset register to survive handover into an FM system rather than arriving as a pallet of ring binders.
  • A rail or highways contractor needs quality records located by chainage along a route rather than by level and grid on a building floor plan, which is what InfraField exists for.

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Dalux.

  • No pricing is published for any paid module, so comparing Dalux against Procore or Autodesk Construction Cloud on cost requires entering a sales process and waiting for a quote you cannot benchmark.
  • There is no cost management, estimating, budgeting or payment application functionality, so commercial teams keep a separate system and someone reconciles the two by hand.
  • The integration catalogue is thin next to the American incumbents, and ERP or finance connections generally mean custom work through the API rather than a listed connector.
  • Support, documentation and product terminology are strongest in Danish and Northern European construction conventions, and teams working to AIA or other North American contract norms will find the workflows do not map cleanly.
  • The free tier is deliberately limited: Field Basic has no checklists, no document control and no reporting, so the free users your subcontractors get are consumers of information rather than participants in a controlled process, and upgrading them is a paid conversation.

Answered, with sources

Questions people ask

Each answer names the page it came from, so you can check it rather than take our word for it.

Is Dalux really free?

BIM Viewer and Field Basic are genuinely free with unlimited invited users. Dalux Box, the full Field product, InfraField, Handover, Tender and FM are paid and quoted privately.

Does Dalux work offline on site?

Yes. Models, drawings and snags sync to the device and the mobile apps are built to work in basements and lift shafts, syncing when signal returns.

Can Dalux replace Procore?

Not on the commercial side. It covers field quality, safety, documents and handover, but has no cost control, budgets or payment applications.

Is it available outside Europe?

It is sold globally and the apps are multilingual, but the customer base, partner network and support hours are centred on Northern Europe.
