John Holland reduces delays on major hospital projects valued at over $500M

For the $577M Victorian Heart Hospital and $515M Thomas Embling Hospital projects in Victoria, Australia, John Holland used Revizto to improve collaboration, automate clash detection, and keep projects on track by minimizing design conflicts and rework.

The Victorian Heart Hospital

John Holland first adopted Revizto on the Victorian Heart Hospital project, Australia’s first dedicated cardiac hospital. Initially used to give site teams early access to models, Revizto became essential as the project advanced. It provided as-built models and PointCloud surveys, ensuring accurate and reliable data was always available.

The Thomas Embling Hospital

Building on this success, Revizto was introduced during the Design Development phase of the Thomas Embling Hospital project, which consists of an addition of 82 secure mental health beds, offices, and a multi-deck car park. Early use of the platform helped John Holland identify clashes, manage design coordination, and streamline project execution.

Common challenges before using Revizto

Before adopting Revizto, projects faced several obstacles:

• Clash detection delays
  ‍Limited transparency and lack of detailed status reports made it difficult to identify and resolve issues early, leading to costly setbacks.
• Disjointed systems
  ‍Managing data across multiple platforms and relying on manual exports created inefficiencies and inconsistencies.
• Coordination complexity
  ‍Without a centralized system, teams couldn’t overlay information during design and shop drawing reviews, making it difficult to identify coordination issues early.

Before implementing Revizto, we faced significant challenges in visualizing issues ahead of time, and effectively overlaying information from various sources. Revizto helped us overcome these challenges by providing a unified platform for collaboration.

How Revizto solved these challenges

Revizto solved these problems by providing a single platform for all project data and models, updated in real time:

• Centralized data
  ‍A single source of truth for both graphical and non-graphical data, accessible to all teams, reduced miscommunication and eliminated fragmented workflows.
• Automated clash detection
  ‍Each discipline uploaded its Revit models, with clashes reviewed fortnightly to resolve issues before they caused delays.
• Improved coordination
  ‍Site engineers, subcontractors, and consultants worked together in one platform, improving communication.

Revizto opened up the work of our trades and consultants, making the information they put together accessible to the site team. This enhanced collaboration and improved workflow efficiency.

Key benefits & results so far

By integrating Revizto across all project stages, John Holland achieved significant improvements in coordination and cost management.

• Early issue detection & reduced rework
  ‍Clash detection and real-time updates helped John Holland identify and resolve conflicts early, preventing costly design changes.
• Cost & time savings
  ‍Applying lessons from earlier phases helped avoid repeated errors, saving time and money associated with reworks.
• Scope change verification
  ‍Utilizing take-off capabilities helped John Holland track and validate scope changes, reducing the risk of budget overruns and misalignment.
• Streamlined workflows
  ‍A centralized platform for all teams, early alignment on processes, and regular reviews kept projects on track.

Although the Thomas Embling Hospital project is ongoing, early results show that Revizto has helped maintain project schedules and improve team coordination, reinforcing its value for complex, large-scale healthcare projects.

Revizto helped us quantify issues in terms of cost. On one multi-staged project, we prevented the same issue from happening in later stages. By accurately coordinating service placements, we avoided rework on joinery and FFE items.

Lessons for other teams

John Holland offers these tips for teams considering Revizto:

• Involve everyone
  ‍Make sure all relevant teams, including non-BIM roles, trades, the client, and design consultants, are actively involved throughout the project to maximize the platform’s potential.
• Capture & use data
  ‍The more detailed your data, the more effective the tool becomes. The data can then be used by various teams, including quantity surveyors, for better decision-making.
• Set clear processes early
  ‍Define workflows and assign responsibilities upfront to avoid miscommunication and delays.

Revizto helped us establish clear workflows and rules of engagement from the start, improving coordination and minimizing conflicts. The status and resolution of coordination issues were then shared with the management team to keep the project aligned.
