200x faster clash detection for Moorfields and UCL Centre for Eye Health with Revizto

Project overview
Moorfields and UCL Centre for Eye Health is a flagship £300 million-plus joint initiative designed to tackle the growing challenge of sight loss in the UK. As the main contractor for this project, Bouygues UK is delivering a world-class facility that relocates services from the current site at City Road, London into a single, state-of-the-art facility in Camden’s Knowledge Quarter.
A landmark healthcare build, coordinated across 20+ disciplines
For Bouygues UK, delivering Moorfields and UCL Centre for Eye Health represents one of the most ambitious and challenging healthcare construction projects in London today. A partnership between Moorfields Eye Hospital NHS Foundation Trust, the UCL Institute of Ophthalmology, and Moorfields Eye Charity, the project spans 47,000 square meters of highly technical space. This includes operating theatres, blackout rooms, specialised research labs, and a dedicated accident and emergency department.
Managing the “data density” was a primary concern for the delivery team. With over 20 disciplines working from their own models, Bouygues UK needed to ensure that every clinical requirement, from the placement of specialized imaging equipment to the intricate ventilation systems, was coordinated perfectly. The project represents a shift toward “democratizing data,” with Bouygues UK using Revizto to make complex BIM information accessible to everyone, from site managers to the hospital’s clinical staff.
More than 100 people across the Bouygues UK team and its subcontractors used the platform daily, with the unlimited user model enabling total collaboration.
"Revizto is used on every [Bouygues UK] project. We were one of the first contractors in the UK to adopt it, and it’s now embedded into our systems. It’s used not only in construction and design management, but also by our pre-construction and bidding teams.”

Using Revizto as a data bridge: “taking the ‘scary’ out of BIM”
On a project as complex as Moorfields and UCL Centre for Eye Health, real-time coordination is the difference between success and costly reworks. Bouygues UK used Revizto to bridge the gap between technical design and production teams. By aggregating models from Revit and Civil 3D into a single, lightweight environment, the team could provide stakeholders with a 360-degree view of the project within hours of a model update.
To date, the team has managed hundreds of design models and thousands of issues within the platform. With Revizto as the "single source of truth" Bouygues UK has moved away from static PDF reports and toward a live, reliable, and navigable digital twin.
"For me, it's about democratizing the data. It's taking the 'scary' out of BIM for some people... They don't have to be a Revit expert or anything like that. They can just go into Revizto and see exactly what we’re talking about."

Simplifying stakeholder feedback with Integrated Issue Management
Traditional design reviews often leave non-technical stakeholders struggling to visualize spatial context and constraints. For Bouygues UK, Revizto was the key to conducting "virtual rehearsals" of clinical spaces. Using the Issue Tracker, clinicians could flag concerns directly within the 3D model, such as the height of a medical gas outlet or the flow of patients through a corridor.
"We've got 20-plus different disciplines, and we're all working in one environment. It’s that single source of truth... It’s about getting everyone involved, from the clinicians through to the guys on site."

Bouygues UK
This created a clear workflow where feedback was contextually linked to the design. Bouygues UK's coordination teams could then address these "issues" and update the model, with the resolution tracked transparently.
This not only increased accountability and accelerated issue resolution, but also improved the quality of the final design and significantly reduced the risk of clinical “misses” that are typically only discovered during construction.

Safety, sustainability and achieving Golden Thread compliance
Beyond standard coordination, Revizto was essential for high-stakes requirements, particularly fire stopping and compartmentation. On a healthcare project of this scale, every service penetration through a fire-rated wall must be identified, verified, and documented before installation begins.
Using Revizto’s Clash Automation, the team was able to detect and resolve these areas digitally at speed, long before they became costly site issues.
“Using older tools, I’d be lucky to get full clash detection done in a week. In Revizto, I can do it in 10–15 minutes.”

This approach also supports Bouygues UK’s compliance with the UK Building Safety Act 2022 and its “Golden Thread” requirement: a live, digital record of building safety information. By keeping fire strategy data coordinated, traceable, and accessible in one environment, the team maintains the audit trail required throughout delivery.
The project also pushes the boundaries of sustainable engineering, with a ground-source heat pump system powered by 120 boreholes reaching 130 meters into the earth. Coordinating the manifold room for this system required the level of precision only possible in an integrated environment.
At the same time, Bouygues UK is delivering a “smart building,” integrating heating, lighting, fire alarms, and booking systems into a connected operational platform, supported by accurate models, drawings, and O&M documentation through to handover.
The project remains on track for completion on time and on budget for December 2026.

How Revizto Collaboration Hub enabled success
- Revizto Collaboration Hub: Central hub for aggregating multidisciplinary models (Revit, Civil 3D, etc.) for Bouygues UK and their partners.
- Unified 2D/3D Environment: Combined models and drawings in one place, using 2D/3D Overlay to ensure complex medical services aligned precisely with architectural documentation across 3,500 rooms.
- Collaborative Clash Automation: Streamlined coordination across 20+ disciplines and helped identify critical penetrations in record time
- Integrated Issue Management: Used the Issue Tracker to capture and resolve clinical feedback directly in 3D, from medical outlets to patient flow.
- Connected Project Intelligence: Gave leadership real-time visibility into issue health and coordination progress for a £300M project with 100+ daily users.
