Back in March when the coronavirus pandemic was just beginning to grip the UK, concerns around hospital capacity were emerging across the nation. In south-east Wales the need was immediate: for the Aneurin Bevan University Health Board, whose area then accounted for more than half of Wales鈥� confirmed covid-19 cases, it was imperative to increase the number of available beds. The region was already home to Wales鈥� biggest ever health infrastructure project, the 拢350尘 Grange University Hospital near Cwmbran, but that was not due to open for another 12 months.

As March drew to a close the hospital project team, led by architect BDP, project and cost manager Gleeds and main contractor Laing O鈥橰ourke, were approached by the health board to see if anything could be done to accelerate completion of the facility, which was being delivered using offsite and design for manufacture and assembly (DfMA).

They agreed to fast-track the build programme so that 350 new beds could be made available as soon as possible to coronavirus patients if required. On 27 April, just four weeks later, the health board took possession of 50% of the space within the hospital. This included most of the ward blocks and the ground floor of the diagnostic and treatment departments, as well as the pathology department, the pharmacy, FM services areas and the mortuary, as well as car parking zones and plant areas. NHS staff now have the ability to mobilise within three weeks to take patients at the new hospital if there is a second spike in covid infections.

In a webinar held as part of 好色先生TV鈥檚 Proud to Help campaign, Laing O鈥橰ourke business unit leader Mike Lewis, Gleeds project director Victoria Head, BDP architect director Adrian Hitchcock and Nicola Prygodzicz, executive director of planning, digital and IT at the Aneurin Bevan University Health Board, shared how the use of offsite manufacturing on the project saved time, reduced the number of site workers and created a collaborative environment for solving problems.

Collaboration from the start

Prygodzicz said that when the Grange University Hospital was first conceived the trust was looking for an acute healthcare facility to provide the specialist care unavailable at local hospitals in the Gwent region. 鈥淚t took a year to get approval after the final business case was submitted. It couldn鈥檛 come quick enough for our clinical teams,鈥� said Prygodzicz, adding that a number of local hospitals were decommissioned during the time it took to deliver the project.

If we hadn鈥檛 had the foresight to use modern methods of construction we would not have been able to respond and help the health board

Laing O鈥橰ourke鈥檚 Lewis described the client鈥檚 brief simply: 鈥淲e need this as quick as we can physically get it.鈥� The next step was setting up the project team, which along with Laing O鈥橰ourke, Gleeds and BDP included WSP and Aecom as engineering consultants and Arup as NEC supervisor. Having the design and construction teams both involved from a very early stage was essential as it enabled everyone to understand each other鈥檚 perspective, said Gleeds鈥� Head.

According to Lewis, it was the use of the NEC suite of contracts that allowed this early collaboration and thereby facilitated the use of design for manufacture and assembly (DfMA). As Head said, this approach was integral to the project鈥檚 rapid delivery. 鈥淲e went into contract on a 137-week programme and we had to put in a lot of work to get partners there to say they were happy with that route,鈥� she said.

A traditional build would have taken 197 weeks rather than the 137 weeks of the DfMA route, she said 鈥� a programme saving of 23%. 鈥淎ny client is going to find that very compelling.鈥�

The design of the building was also approached with an eye to speed, as BDP鈥檚 Hitchcock explained. 鈥淭he building is really about three quite distinct functional zones. The inpatient care zone is constructed as a ward block, and beds have been placed over beds [in the same positions on different floors] to simplify the engineering. The diagnostic and treatment zone is a very regular, simple block based on an 8:1 structural grid.

鈥淚t was about trying to simplify the component parts of the building, so we developed a repetitive, simple structural grid form with adaptable ventilation and engineering services.鈥�

In excess of 50% of the project was delivered through Laing O鈥橰ourke鈥檚 various business arms, including structures and geotechnical specialist Expanded as well as Explore Manufacturing, which is central to Laing O鈥橰ourke鈥檚 DfMA approach. 鈥淲hen we do the next one we will be assembling even more, which will give us even greater pace and greater certainty,鈥� said Lewis.

Speeding up the programme

鈥淚t was a Sunday afternoon when we received a text from Nicola [Prygodzicz] asking: can we talk tomorrow?鈥� said Head. Once Prygodzicz had put the trust鈥檚 request for the accelerated programme to the team, they responded by reprioritising site activities and with a new commissioning strategy designed to allow for zonal access and reallocation of resources. The health board team were able to work alongside the project team on a live site, fitting out the wards with beds and equipment. This collaborative approach condensed the commissioning and soft landings periods from 12 weeks to four weeks.

Head said: 鈥淭he health board were reviewing the trajectories of how covid could hit Gwent, and we developed two plans to allow capacity in the system if required in the pandemic.鈥� Prygodzicz said that knowing how well progressed the hospital was it seemed a 鈥渘o鈥慴rainer鈥� to ask the team if it was possible to make the 350 beds that might be needed to handle the pandemic available sooner, and that getting the revised plan approved in less than a week was a 鈥渞ecord-breaker for the public sector鈥�.

Extensive resource planning was required, balancing the need to deliver a fast-track programme against ensuring the safety of the workforce, all of whom worked in line with government guidelines. 鈥淚t was an absolute priority to make sure this could be delivered safely,鈥� said Lewis.

All those who could work from home did so. On site, stringent hygiene measures were put in place along with patterns and methods of work that allowed for social distancing. Extended hours with split shifts were introduced, with the project team continuing work at weekends as well as over the Easter period to fulfil their commitment to the health board to deliver the hospital early.

There are lessons about how long some things take us to make decisions about in the public sector. Covid is making us reflect on the fact there are ways you can speed these up

Of the costs of this acceleration, Head said: 鈥淥ne of the things that are so very positive is that it鈥檚 a long-term plan 鈥� there hasn鈥檛 been an investment in something that will take be taken down. We have brought expenditure forward but not in an overinflated way.鈥�

According to Laing O鈥橰ourke鈥檚 Lewis, the use of NEC contracts has also kept costs down because they are real-cost contracts that must be agreed before expenditure can be made. 鈥淚t鈥檚 not like these field hospitals which are built at a premium and they鈥檝e had to invest in it at pace,鈥� he said.

Lessons learned

The hospital is now on standby to operate as a fully functioning facility to support health services in south-east Wales in fighting the pandemic as and when infection data suggests it is necessary. Meanwhile, using careful segregation endorsed by infection control, building control and fire officers, work will continue on the remainder of the build with a view to formally completing the scheme this autumn 鈥� six months earlier than planned.

鈥淪itting here saying that fills me with a little bit of dread, but also a lot of passion,鈥� said Head. 鈥淚f we hadn鈥檛 had the foresight to use modern methods of construction we would not have been able to respond and help the health board.鈥�

In terms of what can be learned from the project team鈥檚 experience, BDP鈥檚 Hitchcock sees ramifications for hospital design. The Grange University Hospital鈥檚 arrangement of wards into groups of eight with a way in and way out to allow for one-way transit is something that could be carried forward onto other projects to help deal with potential future pandemics.

For Lewis, another takeaway is the need for shared platforms if the supply chain is to capitalise on the efficiency benefits of using DfMA: 鈥淏ecause all our platforms were the same platforms, we were able to use the digital model as it was always intended. This has to be the way forward.鈥� Hitchcock agreed, saying BDP鈥檚 ability to work directly with Expanded helped minimise error, highlighting the value of being able to freely share data.

So, can the public sector maintain the rapidity of decision-making seen on this project to help respond to the evolving covid-19 pandemic? Prygodzicz believes there are lessons to be learned here too. 鈥淲hile you can鈥檛 do everyday business with the level of [programme and cost] risk that we took, there are lessons about how long some things take us to make decisions about in the public sector,鈥� she said. 鈥淐ovid is making us reflect on the fact there are ways you can speed some of these things up. There are a lot of lessons that can be learned around decision-making and governance for the public sector.鈥�

What the Grange University Hospital project shows perhaps most strikingly is the need to be more strategic around healthcare design and move away from highly bespoke products in hospital construction. If it can be done during a pandemic, then surely it can and should be done in the aftermath.
