SYNCHRO+ is the next evolution announced by Bentley Systems for SYNCHRO 4D, its 4D planning solution that allows to visualize, simulate and manage construction projects. Unveiled at Year in Infrastructure (YII) 2025, this new generation is focusing on artificial intelligence to make 4D planning more intuitive, faster and accessible to more profiles, not just specialists.
In brief:
- SYNCHRO+ is the future evolution of SYNCHRO 4D, announced at Year in Infrastructure 2025.
- It is based on three pillars: connected data (Bentley Infrastructure Cloud, iModel), intuitive design, and IA automation via Bentley Copilot.
- An Early Access Program began in December 2025, with a general availability expected in 2026.
- beCAD, Bentley Systems partner, is now supporting SYNCHRO 4D users and is closely following the deployment of SYNCHRO+.
What is SYNCHRO 4D?
SYNCHRO 4D is a 4D planning software that synchronizes models, teams and calendars for more efficient and controlled projects. It transforms static planning into dynamic visual simulations, linking 3D models and time planning — the famous fourth dimension. The teams gain in visibility and control, from office to field.
Simulate the project before building it: the founding principle of 4D planning.
SYNCHRO+, the new generation driven by AI
Designed from the returns of a hackathon bringing together users and partners in London, SYNCHRO+ Not a simple update: Bentley Systems describes it as a redesign of how construction teams plan and deliver their projects around three pillars.
Connected data, intuitive design, IA automation
SYNCHRO+ based on the Bentley Infrastructure Cloud and Technology iModel, making 4D plans and models accessible both in desktop applications and on the web. The interface is redesigned to transform design models into building models in just a few clicks without juggling with complex files or technical parameters.
Make planning accessible to more project stakeholders, not just planning experts.
Bentley Copilot for Planning
Via Assistant Bentley Copilot, users can describe what they are trying to accomplish: filtering by work areas, suggestions for correspondence between activities and elements of the model, visual presentation for validation. Tasks that used to take hours can be done in a few minutes, with teams keeping their hands on each step.
Deployment schedule
An early access programme (Early Access Program) started in December 2025 in direct collaboration with users, before general availability planned in 2026.
The 10 key points of SYNCHRO 4D
| Key point | In practice |
|---|---|
| 1. 4D planning | Create 4D-based planning and simulations. |
| 2. Work areas | Define areas for better organization of the site. |
| 3. Constructible breakdown | Cut design models into constructable elements. |
| 4. Metres and costs (QTO/WBS) | Cost and volume structures based directly on the model. |
| 5. Federal models | Agregate several models in a unique federated model. |
| 6. Web and mobile access | Follow-up of construction sites and real-time climbs. |
| 7. Risk reduction | 4D simulations to anticipate conflicts before construction. |
| 8. Safety and quality | Early detection of problems to limit recovery. |
| 9. Construction digital twin | Specific models facilitating the commissioning of works. |
| 10. Tender advantage | 4D simulations for more convincing proposals than 2D documentation. |

Frequently Asked Questions
What is SYNCHRO+?
SYNCHRO+ is the next development of SYNCHRO 4D announced by Bentley Systems, which integrates artificial intelligence (Bentley Copilot) to simplify and accelerate 4D planning of construction projects.
When will SYNCHRO+ be available?
An early access programme started in December 2025. The general availability is expected in 2026.
Does SYNCHRO+ replace SYNCHRO 4D?
SYNCHRO+ is presented as the natural evolution of SYNCHRO 4D, designed to unify planning and estimation in a unique platform driven by the AI, more accessible than only to planning specialists.
What role does Bentley Copilot play in SYNCHRO+?
Bentley Copilot is an integrated assistant that helps users complete their planning tasks: area filtering, activity/model matching suggestions, and visual presentation for validation, while allowing the user to keep the final control.
