instance they always got what they needed, but in a different manner to usual, because all the contractors were focused on the field hospital concept.” Someone like Caroline Mulholland is key on a project such as this, because her experience means she understands the clinical drivers and questions to ask. “I worked closely with the clinical team, BDP, and NG Bailey to make sure nothing was missed,” she explains. “It was easy to focus on bed bays, and to overlook issues like patient flow, infection control, and issues like donning and doffing – where the clinicians change in and out of PPE.”


Visualising the ‘points of detail’ To visualise the points of detail, the layout was marked out on the floor with tape. It might have looked like basic stuff from the design team, but it worked. The aim was to create three zones – Red for COVID-19 infection – where staff wear full PPE; the Amber zone as the ‘breakout area’ for all staff, with the requirement here for minimal PPE and scrubs, and the Green zone for all support services – the delivery of all supplies, food, materials, and medicines, where no PPE is required. The challenge is how to have each zone operating, and for nothing to come into contact with the Red zone. For example, movements in and out of the Red zone must be able to occur without crossing the Green and Amber areas. The fourth zone was the 100-bed mortuary. All these factors were covered through true and rapid collaboration.


John Fowler, IHP Contracts manager, says: “The discussions needed to work out these solutions were much easier on this scheme, because we were all not just in the same location, but able to see and


says: “It was not unusual for us to come together as a small group, identify a challenge, and then someone would literally sketch out an answer with pen and paper. We’d then agree it and make it happen.”


Need for a VIE


By Tuesday evening it had been agreed that the site needed at least one vacuum insulated evaporator (VIE) unit – in effect a giant thermos flask which almost all hospitals have located outside their buildings. BOC can then re-supply easily. For us that meant assessing the loading bay to the rear of the convention centre. “The service yard was ideal, but very close to the Hilton, live rail lines, and above the arches of the car park,” explains Paul Aulton. “Bear in mind also that the building is grade II listed. The space was surveyed by a structural engineer. Then, overnight, a concrete base had appeared, so we could set up the 12 m high tank and then set about working out how to pipe the oxygen into the field hospital and around the wards.”

speak to each other instantly. It’s unusual for specialists to be working in conjunction with contractors and the client in such a hands-on way. It allowed us to focus on the issue and deal with it.” “In many ways,” adds Ged Couser, “it felt like a series of scenes from Apollo 13. We knew had a problem – only certain materials to work with and limited time – so, we just got on with it.” Paul Aulton


The NG Bailey team set about constructing a pipe framework offsite in its factory, while the design team and builders formed four access holes through the external fabric of the building – after appropriate consultation with the local planning authority. “Oxygen was just one of the ‘external’ issues that if we got wrong would limit the operational capability of the hospital,” explains Martyn Frackelton. It was a reminder that we could build something, but it all needed to be connected to run the facility. That meant we needed to check that what we did was not going to impact upon movements of patients, supplies, and staff
