Dalux

Overview

Dalux is a suite of construction software built around 3D BIM visualization, spanning design, site work, and asset operation. It is strongest for project teams that need model review or site-task workflows alongside a wider set of construction tools; the free options are useful, but limited to three active projects or buildings.

Its products include BIM Viewer, Dalux Box, Tender, Dalux Field, InfraField, Dalux FM, and Handover. Dalux serves contractors, developers, owners, engineers, tradespeople, and architects. Founded in 2005, it is headquartered in Copenhagen, Denmark.

Key features

Model viewing and comments

The free BIM Viewer supports native BIM, IFC, and drawings, with viewing, measuring, filtering, and comments. That makes it a practical choice for teams that need to inspect project information and discuss it in context, without paying for a broader product. It is not the same as access to Dalux’s full product suite.

Site tasks

Field Basic supports 3D model uploads, assigning site tasks, and mobile access, with unlimited tasks. The task allowance is generous for a free punch-list tool, but the three-project/building cap can rule it out for teams managing more concurrent work.

Connections and workflow extensions

Dalux offers plugins for Revit, Navisworks, Tekla, and Archicad, with supported software versions stated in its help center. Connections among Dalux products and an API also support custom workflows and dashboards. API use requires a company license and an API key from a Dalux Customer Success Manager, so it is aimed at licensed teams rather than casual users.

Security and support

Dalux says it maintains an ISO/IEC 27001-certified information security management system and holds ISO/IEC 27701 certification. Its general terms provide online training and support to appointed Super Users by phone or email. Phone support has weekday hours, and Dalux aims to reply to email within 24 hours on working days.

Pricing

Dalux uses a freemium model. BIM Viewer costs free for BIM viewing and commenting, while Field Basic costs free as a punch-list tool with unlimited tasks. Both are limited to three active projects or buildings under the free-use terms, though invited users are unlimited. These are meaningful entry points for small or focused teams, but the project cap matters more than the user count as work scales.

Paid Dalux products have custom pricing; contact Dalux or request a demo. The free products do not establish the cost of expanding into its wider suite, so teams considering paid tools should evaluate that separately.

Platforms

Dalux supports Android, iOS, web, and Windows, as well as an API. Dalux Mobile requires iOS 16.0 or Android 11.0 or higher. Dalux Desktop is a Windows application intended to provide browser features with improved performance, particularly for 3D graphics. That gives model-heavy work a desktop option, while mobile access suits field tasks and review.

Who it's for

Dalux fits construction and built-environment teams that need BIM review, comments, or site-task coordination, especially when they want unlimited invited users on a small number of active projects. Its broad product range may also suit organizations handling work across the construction lifecycle, though paid-product pricing is custom. It is a weaker fit for teams whose project volume exceeds the free cap or who need API access without a company license.

Pros and cons

• Free model review is capable: support for native BIM, IFC, drawings, measuring, filtering, and comments gives teams more than a basic file viewer.
• Field Basic has unlimited tasks: teams can use task assignment and mobile access without a task quota, within the three-project/building cap.
• Invited users are unlimited on free use: the cap is on active projects or buildings, not the number of collaborators.
• Free scope is constrained: three active projects or buildings can be a hard ceiling for active construction portfolios.
• API access has prerequisites: it requires a company license and an API key from a Customer Success Manager.
• Paid costs require a sales conversation: custom pricing makes it harder to compare expansion costs before contacting Dalux.

Alternatives

For a wider construction document management software comparison or a broader construction management software shortlist, compare tools by the workflows your team needs. If model review is the priority, browse 3D model viewer software.

ProjectTeam.com is worth considering if you want a free contributor tier for access to invited projects, shared forms, and files, with access dependent on a subscriber. Trimble Viewpoint Vista is an alternative with cloud-hosted and on-premises deployments and sales-based pricing. BIMcollab is another freemium option; its Basic annual plan is €12.50 a month, billed annually, and includes 10 GB storage per space and one guest access. Newforma Project Center offers a Contract Management Edition with RFIs, submittals, contract management, and field management, at custom pricing. Asite is a paid alternative with no free plan; its listed starting prices are from $50 (priced on request) for Asite 3D Repo and from $70 (priced on request) for Common Data Environment. Newforma ConstructEx uses tailored pricing, with no monthly subscription fees and unlimited users. Newforma Konekt is another paid option. Truvect is another paid option.

Verdict

Dalux is a strong fit for construction teams that need BIM viewing and comments or a mobile site-task tool, and its unlimited invited users and tasks make the free entry points practical within their project cap. Look elsewhere if three active projects or buildings are not enough, or if you need API workflows without a company license. For larger deployments, custom pricing means the cost of moving beyond the free tools should be part of the decision.
