Rethinking Design series: Hospitals

Hospital building programmes are in the spotlight like never before.

The delivery of the Nightingale hospitals to provide emergency relief care during the first weeks of the coronavirus crisis demonstrated the pace at which health facilities could be built 鈥� and proved that the UK construction sector has the capability to deliver these types of healthcare facilities on demand.

Add to this a government programme to build 40 hospitals within the next decade, as well as the implications of the pandemic on the physical makeup of hospital buildings, and it is clear that the design and the way in which these facilities are delivered is certain to change in numerous ways over the coming years.

While certain sectors have dried up in the wake of the pandemic, firms are flocking to the booming healthcare sector 鈥� an area that the government has promised to spend big on. The Department for Health and Social Care has revealed 32 hospital projects to be built as part of its Health Infrastructure Plan 1 and 2 (HIP1/HIP2), and the race is on for both those trying to get hospitals built and those looking to build them.

鈥淕iven the way the market is at the minute, healthcare bids are coming out thick and fast, by the week. It is quite a thing,鈥� says Ged Couser, principal at architect BDP. 鈥淭here is the HIP 1 and HIP 2 lists of hospitals, and there is a little bit of an arms race as to which trusts can get out of the blocks first. There鈥檚 quite a lot of competition, and the market is responding to that.鈥�

Couser concedes that, while there are limitations to the capacity of the construction sector, there is a solution to this. 鈥淚 think what it means is that we鈥檝e got to design buildings and hospitals and healthcare facilities in a very particular way to make sure that they are deliverable,鈥� he says, 鈥渁nd that they can be built to the budgets and to the programmes that we鈥檙e being faced with.鈥�

We鈥檝e designed a lot of high-quality, RIBA award-winning hospitals over the years. But a common theme runs through them all 鈥� intelligent offsite construction

There is definitely a need for different design elements arising from both the covid-19 pandemic and the increasing use of manufacturing technology in the construction of hospitals. According to Gleeds鈥� director of healthcare, Victoria Head, this will become evident in a number of ways, but one of the key areas is ventilation systems.

鈥淭he provision of oxygen is super important,鈥� she says. 鈥淪o most new-build hospitals will have med pipes, medical gases, including oxygen. And that provision and resilience of oxygen is very important for covid.鈥�

Another aspect that is likely to change is the provision of negative pressure rooms, so that patients can be isolated. Head also highlights the less obvious design ramifications of covid, saying that the ability to implement social distancing has become a quandary for those looking to design a hospital.

鈥淚t comes down to the less technical design elements that allow for social distancing to be maintained,鈥� she says. 鈥淲aiting rooms need to get bigger, car parks need to get bigger 鈥� there鈥檚 all of that.鈥�

But, as Head says, it鈥檚 a careful balancing act to design and build in these elements, particularly as spaces such as waiting rooms are the parts of these facilities that have traditionally been designed to use space as efficiently as possible. 鈥淵ou wouldn鈥檛 want to go into designing these facilities that are vast and then not used, because that becomes a very expensive asset to maintain. But at the same time, if it鈥檚 going to be around for a while, and we鈥檙e going to be maintaining these distances, we are going to have to think of providing more circulation space.鈥�

Rory Pollock, Laing O鈥橰ourke鈥檚 health sector lead, highlights the fact that smaller wards and single-bed rooms are definitely going to be in greater demand as a consequence of the pandemic. 鈥淚f there has ever been a need to accelerate design for manufacture and assembly (DfMA) and modern methods of construction (MMC), it is now,鈥� says Pollock. 鈥淭he fact that we have diminishing assets from a healthcare point of view that need rapidly upgrading, but also the fact that these deliveries are made at pace, at speed, which is absolutely the directive being given, [mean] we can鈥檛 really deliver these traditionally any more.鈥�

BDP鈥檚 Couser agrees. 鈥淲e鈥檝e designed and delivered a lot of large hospitals, really high鈥憅uality, RIBA award-winning hospitals over the recent years. But there is a common theme that runs through them all. And that is about using intelligent offsite construction.鈥�

The 拢3.8bn healthcare injection

With a 拢3.8bn programme of works up for grabs it is unsurprising that firms are looking to expand into the healthcare sector. Following confirmation of the 40 hospitals that will be built as part of the government鈥檚 programme (see panel 鈥�40 New hospitals, the government鈥檚 plan鈥�, below), offsite construction specialist Merit launched Merit Health, a new healthcare division focused on building hospitals faster, more cost-effectively and sustainably.

The business also plans to deploy enhanced infection control, which can make wards covid-19 safe. Tony Wells, managing director at Merit, claims the government is only going to deliver its ambitious building programme if companies like Merit enter the fold and show how it can be done. 鈥淭his will also be a critical element towards achieving the NHS鈥檚 net zero carbon commitment,鈥� he says. 鈥淥ur individual hospital bay ventilation and extraction technology also means no cross-contamination, which is critical as the NHS continues to deal with covid-19 as well as future potential pandemics.鈥�

Merit Health will use the company鈥檚 offsite manufacturing technology to significantly reduce long-established building construction timelines, something that Wells says will be critical in supporting the government鈥檚 hospital building pledge. According to Merit Health, while a typical acute facility takes three to four years to build, from inception to handover, its offsite approach can deliver projects in half that time. Around 75% to 90% of the buildings are manufactured at the 270,000ft虏 Merit factory in Cramlington, Northumberland.

Gleeds鈥� Victoria Head agrees it is vital that DfMA and MMC are integrated into projects from the outset and says that one of their most significant strengths is the fact that walking into a hospital built using these methods one would be unlikely ever to know they were built using non-traditional construction.

And this does seem to be integral. According to Laing O鈥橰ourke鈥檚 Paul McNerney, director of UK building, it is imperative for the successful delivery of healthcare facilities that NHS trusts engage with the supply chain early and embrace DfMA and MMC from the start. 鈥淚 think one of the concerns and reservations that clients often have around modern methods is that it鈥檚 somehow restrictive, and removes bespoke design of a particular property, leaving the landlord with a grey monolithic box,鈥� says McNerney. 鈥淭hat isn鈥檛 the case though. We鈥檝e been building in this manner for more than 10 years, going back to projects, in the south鈥憌est of England, where the factory was first opened.鈥�

As an example, Laing O鈥橰ourke has managed to refine a broad palette of products, be they structural elements, services, bathroom parts, or facades, meaning there is the capability to deliver manufactured yet bespoke buildings.

鈥淲e鈥檝e now got a very thorough catalogue of techniques and approaches,鈥� McNerney says. 鈥淪pecific products can be brought together in different ways to achieve the outcome.鈥�

While the ability to offer clinical specificity and desirable aesthetic design will always be significant, providing scale on repeatable elements such as single bedrooms is key to maximising efficiency from both a design and a construction perspective.

McNerney鈥檚 colleague Pollock says: 鈥淲e can create a bit of an investable model that way. You have got single-bed accommodation, where you鈥檝e got an excess of 16,000 bedrooms, which arguably could be all the same across the country. It鈥檚 an investable model for a number of different contractors that we can invest in and roll out.鈥�

This idea of combining individuality and uniformity, that there needs to be a more cohesive approach from different hospital trusts, is something the sector, the government and the NHS will need to work together to achieve. And it is essential they do so as, without an efficient design and construction process, the deliverability of the hospital building programme will be challenging if not impossible.

Pollock says: 鈥淭here is such a huge opportunity from a procurement point of view, to not have 40 separate designs with 40 separate designers and 40 separate contractors. There鈥檚 a responsibility really among all of us in the sector to combine and share.鈥�
