Trimble Quadri

Trimble Quadri is an infrastructure collaboration platform built around a shared project model. It suits multidisciplinary teams coordinating work across design and construction, especially on road and rail projects. Its strongest case is keeping model coordination, quantity views and construction records connected; its Windows requirements and license-based access narrow the fit.

Overview

Quadri gives infrastructure project participants a shared central model, with cloud sharing intended to provide one common source for project data. It connects model modifications to work processes and uses notifications and alerts to help teams follow issues or clarify changes. That makes it more suited to continuing project coordination than to a one-off model review or isolated estimate.

Its scope also reaches from model views and quantity takeoff to as-built records. Teams can capture digital assets in an as-built model and keep project documentation updated as construction progresses. Quantm within Quadri can compare road or rail alignment alternatives, while sustainability planning can forecast CO2 emissions from construction and road or rail use.

Key features

Model coordination and review

Quadri supports multi-discipline work in a shared model, with 3D, longitudinal and cross-section views for examining the project. Table views support quantity takeoff across the model. The combination is useful for teams that need model review and quantities in the same infrastructure workflow, though the free Viewer provides viewing and measuring rather than editing.

Connections and planning

Connectors include Trimble Connect, Novapoint, Trimble Business Center, Tekla Structures, SketchUp, Tilos, Quantm, ProjectWise, Rhino Grasshopper, Open Roads Designer, Revit and Civil 3D. APIs can be used to customize features and workflows and connect data to Quadri. This breadth helps teams working across those tools; the value depends on whether their project workflows use them.

Quantm can evaluate alignment options for road and rail corridors, and Quadri can forecast CO2 emissions for construction and corridor use. These planning capabilities extend its role beyond model coordination for infrastructure teams weighing route alternatives and sustainability impacts.

Pricing

Quadri has paid licensing, custom pricing and a 30-day trial. A license is required to use the full product, along with Trimble Identity credentials and an installation. The Viewer is free: it is a read-only display tool for viewing and commenting on models and measuring distances and areas. That makes it suitable for project managers and construction decision makers who need to inspect a model without a full Quadri license; it does not replace the licensed product for teams coordinating and modifying project work.

Platforms

Quadri supports Windows, web, API and self-hosted deployment options, with both Connected Projects and On-Premise projects described. Windows requirements include at least 32 GB of RAM and 50 GB of free disk space; cloud features require an internet connection. Quadri for Windows 2024 reached end of life on May 1, 2026. End-of-life versions no longer receive technical assistance, bug fixes, updates or security patches, so teams should account for version support when planning deployment. Support services are open on workdays from 09:00 to 16:00 GMT+1; users without a support agreement are directed to a local dealer or email support.

Who it's for

Quadri is aimed at infrastructure project participants working across the project lifecycle, especially multidisciplinary teams that need a shared model, issue follow-up, model-based quantities and current as-built documentation. Its road and rail planning features also suit corridor teams assessing alignment alternatives. The free Viewer fits project managers and construction decision makers whose needs stop at viewing, commenting and measuring. Smaller jobs needing only a standalone estimate or users without a capable Windows system are less likely to benefit from the full platform.

Pros and cons

• Pro: Shared model collaboration, issue notifications, model views and quantity takeoff support connected coordination across disciplines.
• Pro: As-built asset capture and updated documentation help carry project records forward as construction progresses.
• Pro: A free read-only Viewer gives project decision makers model viewing, comments and measurement without a paid license.
• Con: The full product requires a Quadri license, and custom pricing makes the cost harder to assess before contacting Trimble.
• Con: At least 32 GB RAM and 50 GB of free disk space set a substantial floor for Windows installations.
• Con: End-of-life Windows versions lose assistance, fixes, updates and security patches, so version currency matters.

Alternatives

For broader comparisons, start with BIM Software if you are choosing a model-based platform, or compare Construction Scheduling Software and Project Estimation Software when scheduling or estimating is the primary need. Construction Estimating Software is another category to consider when estimating, rather than shared infrastructure models, leads the decision.

Buildxact is a freemium option with a free Go plan offering five complimentary credits, AI estimating, professional proposals and Home Depot material ordering; choose it when those estimating and ordering tools are the priority. STACK has a free tier capped at one active project per month, 300 plan pages, 50 measurements per project and one viewer seat, making it a fit for limited project takeoff needs. Jestimate offers a free tier for readers considering another web-based freemium option.

Planning Poker, Planning Poker Online, PlanningPoker.live and UltimatePlanningPoker are planning poker alternatives for readers seeking tools in that category. Trimble Viewpoint Vista is a paid ERP option with cloud-hosted and on-premises deployments; consider it when ERP is the need.

Verdict

Choose Trimble Quadri if an infrastructure team needs a shared project model that ties issue follow-up to model changes, supports model-based quantities and carries records into construction. The free Viewer is a practical access point for decision makers who only need to inspect, comment on or measure models. Look elsewhere if you need a full license price up front or your Windows environment cannot meet the stated requirements.
