Engineering for longevity in the New Hospitals Programme’s phased rollout

By Ewa Ambrosius, Operations Director

The New Hospitals Programme (NHP) represents one of the most significant investments in UK healthcare infrastructure in a generation. As we embark on this ambitious journey, from addressing immediate RAAC priorities in Wave 1 (2025-2030) to realising long-term visions in Wave 3 (2035-2039), we face a once-in-a-lifetime opportunity to redefine how we approach healthcare construction. However, the true challenges extend far beyond simply delivering new hospitals, they actually lie in building healthcare facilities that will serve communities effectively for decades to come.

The wave approach
The NHP’s wave system presents a unique engineering challenge: how do we ensure that hospitals built in 2025 remain as functional, efficient and adaptable as those completed in 2039? This phased approach demands not just construction expertise, but forward-thinking structural engineering and civil engineering that anticipates the evolution of healthcare delivery.

Beyond Modern Methods of Construction
Much of the conversation around the NHP has rightly focused on Modern Methods of Construction (MMC) and modular building techniques. These approaches offer significant advantages in speed, cost-effectiveness, and quality control. By shifting substantial portions of the building process off-site, we can dramatically reduce construction timelines, minimise waste, and mitigate on-site disruption.

Yet the engineering considerations extend far beyond the construction methodology. Crucially, the structural integrity of these facilities must be designed to accommodate decades of evolving medical technologies, changing patient demographics, and shifting care models. This requires sophisticated solutions that builds in adaptability from the ground up.

Engineering adaptable foundations
Healthcare facilities are among the most complex buildings to design and construct. They house sophisticated medical equipment, accommodate diverse clinical workflows, and must operate 24/7 without interruption. The structural and civil engineering considerations are equally complex.

For instance, future-proofing a hospital’s structural frame requires anticipating potential expansions, equipment upgrades, and reconfiguration of spaces. This might mean designing floor plates with greater load capacities than currently needed, incorporating expansion joints that accommodate building extensions, or creating structural systems that can be modified with minimal disruption to the live environment.

Similarly, civil engineering elements, such as drainage systems, must be designed with future scenarios in mind. A hospital’s infrastructure must be robust enough to withstand increasing climate challenges, while flexible enough to adapt to changing operational requirements.

The challenge of longevity
The materials we select today will determine the resilience and sustainability of these facilities for decades. Traditional construction materials like concrete and steel remain fundamental, but their application must evolve to meet the NHP’s ambitious timeline and sustainability goals.

For example, low-carbon concrete formulations and high-strength steel can reduce the environmental impact while maintaining structural integrity. Innovative composite materials might offer better performance characteristics for specific applications. The key is selecting materials not just for their immediate benefits but for their long-term performance and adaptability.

The methods of assembly are equally important. Designing connection details that facilitate future modifications can dramatically extend a building’s life span. This might include bolted connections rather than welded ones in strategic locations, or designing partition systems that can be reconfigured without affecting the primary structure.

Integration of systems
Perhaps the most significant engineering challenge in healthcare facilities is the integration of building systems. Structural and civil engineering must work in harmony with mechanical, electrical, and internal drainage systems, as well as pneumatic tube, medical gas systems and increasingly complex IT infrastructure.

This integration requires collaborative engineering from the earliest design stages. For instance, creating interstitial spaces between floors or outside the main floor plan can provide accessible routes for services, allowing for maintenance and upgrades without disrupting clinical areas. Similarly, designing structural systems with integrated service zones can facilitate the installation and future modification of building services.

Standardisation without stagnation
The NHP’s ambition for standardisation aligns perfectly with the principles of good engineering. Standardised components and systems can improve quality control, reduce costs, and accelerate construction. However, standardisation must not come at the expense of innovation or adaptability.

The engineering challenge is to develop standardised solutions that incorporate flexibility by design. This might include modular structural systems that can be configured in multiple ways, standardised connection details that facilitate future modifications, or civil engineering strategies that anticipate site-specific challenges while maintaining consistent performance standards.

The role of digital engineering
Digital tools are transforming how we approach structural and civil engineering for healthcare facilities. Building Information Modelling (BIM) allows us to create detailed digital twins of hospitals, simulating their performance under various conditions and scenarios. This enables us to identify potential issues before construction begins and to plan for future adaptations.

Similarly, computational design tools allow us to optimise structural systems for specific performance criteria, whether that’s minimising material usage, maximising flexibility, or optimising construction sequencing. These digital approaches are essential for meeting the NHP’s ambitious timeline while ensuring the long-term performance of these critical facilities.

Collaboration: The foundation of success
Perhaps the most crucial factor in engineering for longevity is early collaboration between healthcare organisations, developers, and engineering consultancies. Early engagement allows engineers to influence key decisions that will determine a facility’s long-term performance and adaptability.

This collaborative approach enables us to develop integrated solutions that address immediate construction challenges, while building in the flexibility needed for future adaptations. It also allows for the education of all stakeholders about the advantages and limitations of different engineering strategies, ensuring informed decision-making throughout the project lifecycle.

Engineering for generations
The New Hospitals Programme is not just about addressing immediate healthcare infrastructure needs; it’s about creating a legacy that will serve communities for generations. Our responsibility extends beyond ensuring these buildings stand up, we must ensure they can stand the test of time.

By focusing on adaptability, integration, and long-term performance, we can create healthcare facilities that will evolve with changing needs and technologies. This requires sophisticated engineering that anticipates future scenarios while addressing immediate constraints.

The wave system of the NHP gives us a unique opportunity to learn and adapt our approach as the programme progresses. By applying the lessons from each wave to subsequent phases, we can continuously improve the resilience, adaptability, and sustainability of these vital healthcare assets.

The true measure of success for the NHP will not be how quickly we can build these hospitals, but how effectively they serve communities for decades to come.
