The Challenge
A leading NHS trust, faced with the imperative to modernize its mental health facilities, embarked on a journey to redesign a mental health unit that not only met the rigorous NHS AEDET (Achieving Excellence in Design Evaluation Toolkit) standards but also effectively addressed the therapeutic needs of its patients. The existing facility presented numerous challenges in achieving a patient-centric environment that supported recovery and wellbeing. It lacked spatial efficiency, natural lighting, and the integration of modern healthcare technologies. This required a meticulous design approach that prioritised both compliance and innovation.
The NHS trust needed a solution that could seamlessly incorporate aesthetic and functional design elements while ensuring timely project delivery within budget constraints. The challenge also involved managing intricate stakeholder requirements spanning across clinical staff, patients, and regulatory bodies, all while ensuring a design conducive to healing and recovery.
Beyond the AEDET criteria of use, build quality, and impact, the trust also had to satisfy the Psychiatric Intensive Care Unit (PICU) design guidance and ligature-risk assessments that govern acute mental health environments. Sightlines for observation, anti-ligature fixtures, and calming sensory palettes all had to be reconciled with everyday clinical workflows, fire safety regulations, and infection control standards. Legacy 2D drawings for the existing building were incomplete and, in places, inconsistent with as-built conditions, which made early-stage planning particularly difficult. Without a single, reliable source of truth for the existing structure, the risk of costly late-stage design changes and on-site rework was high.
How Adyantrix Approached It
Adyantrix leveraged its expertise in Building Information Modelling (BIM) to address these multifaceted challenges. From the outset, the Adyantrix team prioritised understanding the diverse requirements of all stakeholders and integrating these elements into a cohesive design plan. By employing a BIM-driven approach, Adyantrix facilitated enhanced collaboration between architects, engineers, and contractors, ensuring all parties were aligned with the project goals.
The process began with a comprehensive assessment of the existing facility using 3D scanning technologies, which provided valuable insights into the spatial and structural characteristics of the building. This informed the subsequent stages of design and planning, allowing Adyantrix to propose solutions tailored to the specific needs of the mental health unit — an approach detailed further in our case study on scan-to-BIM for NHS estate capital planning.
Adyantrix also established a shared BIM execution plan aligned with ISO 19650 workflows, giving the trust's clinical advisers, estates team, and construction partners a common data environment from which to review design intent. Weekly coordination clinics were held around the federated model, allowing occupational therapists and ward managers to comment directly on room layouts, sightlines, and material choices before designs were locked down. This iterative, model-based review cycle reduced the number of late design changes and gave clinical stakeholders far greater confidence that the finished unit would support both staff observation needs and patient dignity.
Technical Implementation
Adyantrix implemented a robust BIM framework using advanced software tools such as Autodesk Revit, Navisworks, and Dynamo for generative design scripting. These technologies enabled the creation of highly detailed 3D models that encapsulated every aspect of the building’s architecture and engineering components.
The team employed Revit to create accurate architectural plans, integrating these with structural and MEP (Mechanical, Electrical, and Plumbing) models to ensure a comprehensive design that considered all technical aspects. The use of Navisworks facilitated effective clash detection and ensured that potential conflicts were resolved before construction commenced, thereby minimising delays and cost overruns.
Furthermore, Adyantrix created 3D visualisations and renderings that provided stakeholders with an immersive view of the proposed design, making it easier to secure approvals and finalise design specifications. These visual aids were instrumental in presenting the therapeutic environment envisioned, complete with optimised lighting, natural ventilation, and patient-friendly spaces that promote well-being.
The BIM models were also enriched with COBie-compliant asset data, capturing manufacturer details, maintenance schedules, and warranty information for anti-ligature fittings, tamper-resistant sanitaryware, and specialist HVAC equipment. This gave the trust's facilities management team a structured digital handover package rather than a stack of disconnected PDFs, allowing planned preventative maintenance to begin from day one of occupation. Dynamo scripts were used to automatically check room areas and daylight factors against AEDET benchmarks as the design evolved, flagging any spaces that fell short of target natural light levels or minimum floor areas so the design team could intervene early rather than at the end of a design stage.
Results Delivered
Adyantrix successfully delivered a state-of-the-art mental health facility that not only met but exceeded the NHS AEDET standards. The project resulted in a 20% improved spatial efficiency and a significant reduction in projected construction timelines due to the early detection of design conflicts. By incorporating extensive stakeholder feedback into the design process, Adyantrix created a facility that far better accommodates patient needs, promoting healing through enhanced environmental psychology.
The delivery of the project within budget and on schedule reinforced the trust’s confidence in BIM as a key enabler of cost-effective healthcare design. This success story emphatically demonstrated the ability of Adyantrix to harmonise complex design requirements with operational realities.
Clash detection carried out in Navisworks across architectural, structural, and MEP models identified coordination issues well before they reached site, contributing directly to the reduction in projected construction timelines — the same disciplined coordination approach we applied on a related acute-care project, zero-clash MEP coordination for an operating theatre. The federated model also supported a smoother handover process, with the COBie-enriched dataset giving the trust's estates team a structured baseline for ongoing asset management. Post-occupancy feedback gathered from ward staff highlighted the improved sightlines, calming material palette, and increased natural light as tangible improvements over the previous facility, reinforcing that the AEDET-aligned design translated into a measurably better day-to-day environment for both patients and staff.
Lessons Learned
One of the key takeaways from this project was the importance of early stakeholder engagement and iterative design reviews. Regular feedback loops ensured the adherence to both technical standards and patient-centred values. Additionally, deploying a robust BIM strategy from the onset played a critical role in realising a cohesive and clash-free design, highlighting BIM's indispensable role in modern healthcare projects.
The project also underscored the value of embedding clinical and safety expertise directly into the modelling process, rather than treating ligature-risk and observation requirements as a separate compliance exercise reviewed only at the end of each design stage. Involving ward-level staff in model walkthroughs surfaced practical concerns, such as door swing directions and furniture placement, that would have been difficult to identify from drawings alone. Adyantrix noted that the automated AEDET benchmark checks built into the Dynamo workflow saved considerable review time and could be adapted for future healthcare projects with different regulatory checklists.
Next Steps
Capitalising on the success of this project, the NHS trust plans to expand these BIM methodologies to other units within its portfolio, aiming for a system-wide adoption of technology-enhanced design processes. Adyantrix, now a preferred partner, is set to assist in future projects, ensuring continuous improvement in healthcare infrastructure design.
Building on the COBie-enriched handover model, the trust is also exploring how the digital asset data can feed into its computer-aided facilities management (CAFM) system, enabling predictive maintenance scheduling for critical mental health environments. Adyantrix has proposed a standardised BIM template for future mental health unit refurbishments, incorporating the automated AEDET compliance checks developed during this project, so that lessons learned here can be applied consistently across the trust's wider estate.
