Explore productConnected decisions
Construction work does not move in isolated stages.
Commercial activity, building concepts, system placement, and project work each carry context into the next decision. HAT focuses on the tools that help keep that context visible.
Model coordination
Review building systems in the model context where routing and multidisciplinary choices are made.
Capabilities
Technology shaped around practical construction context.
HAT works across operational, visual, model, and workflow needs without asking one generic system to explain every part of the work.
Workflow automation
Shape repeatable internal paths around the decisions and handoffs your team manages.
AR visualization
Give building concepts more spatial context through augmented reality and visualization.
3D modeling
Keep building geometry and review context visible for technical conversations.
MEP/HVAC coordination
Place and review MEP and HVAC systems in the context of the building model.
Custom internal software
Create focused applications for workflows that generic software does not fit.
System integrations
Connect purposeful tools and information flows around the work they support.
Industry context
Built for the teams that bring buildings together.
Find the context closest to your organization, then explore the related products and workflow paths.

Explore industryHow HAT builds
A product approach grounded in the work, not a generic template.
The goal is not more software for its own sake. It is a better fit between the information people need and the construction decisions they need to make.
- Built around real construction workflows
- Clear enough for daily operational use
- Modular enough to grow with the company
- Designed to connect office, model, and field information
- Focused on reducing unnecessary handoffs and repeated work
Responsible engineering
Built with practical safeguards in mind.
HAT approaches software with clear ownership, sensible data handling, and controls that match the purpose of the system. The marketing site keeps its contact data separate from future product applications and does not add third-party tracking by default.
