of these multi-service corridor modules, and 10 mechanical and electrical risers, as well as rooftop and basement plant modules, and a complete modular wiring solution. Adopting this standardised approach meant that we significantly reduced the labour hours required on site, which created a safer working environment, as fewer people were required. It also led to faster installations, with a 40% reduction in hours for the primary corridor services and dry-lining installation alone, which in turn saved time on the overall project programme.

Minimising disruption The benefits of MMC are well documented, but the time, cost, quality, and safety benefits which offsite manufacture brings should not be taken for granted, especially on healthcare projects, where one of the biggest challenges we face is ensuring minimal disruption to patients and staff on site. Modern methods of construction help minimise the impact on clinical activity, as we can refurbish areas like operating theatres in a phased approach, ensuring that vital surgeries can still take place. We also utilise Building Information Modelling (BIM) for design and offsite manufacturing on these projects, so no hot works need to be carried out on site, reducing the fire risk, and improving site safety for all. Items are also delivered as a set, bolted together, so the amount of noise generated in construction and installation is greatly reduced for patients recuperating in hospital.

Our work at the Chesterfield Royal Hospital saw us face the challenges of working on a live hospital site. We provided new, state-of-the-art operating theatres for the hospital, and were able to use a phased approach to refurbish its existing surgical department, ensuring that adjacent theatres could still function while the upgrades were being made.

Complex logistical challenges The hospital was updating its 40-year-old operating theatres to create cutting edge facilities which are at the forefront of UK hospitals. Our work on the project took several years to complete, and involved some complex logistical challenges. Using our BIM, we demonstrated and coordinated new services through the existing services structures, ensuring that new services could be both efficiently installed and easily maintained. At points we were working across the corridor from where live operations were taking place, so patient and staff safety was of paramount importance. Our use of MMC meant there were no unplanned disruptions to the daily operational functions of the hospital, and patient care was maintained throughout. Our teams have also recently delivered

Creating a sustainable future While cost and time efficiencies are naturally important considerations for clients, designing more sustainable hospitals is also high on the agenda. The UK Government has committed to reaching net zero carbon by 2050. This means significantly reducing emissions, and the NHS has therefore committed to reaching Net Zero as soon as possible. Increasingly, clients want buildings and construction methods which are more sustainable, and can help them reduce their carbon footprint.

MMC and offsite manufacturing will undoubtedly play a big role in the aim to

be net zero carbon, as the techniques mean there are fewer people working on site, which also means reduced numbers of people driving there daily. ‘Offsite’ also reduces the number of deliveries required to site, and there is less waste during production, as services are designed to be more efficient, while more complex modelling and factory quality control mean errors are reduced.

At the University Hospital of North Tees’ new energy centre, we were able to remove more than 6,000 labour hours and 180 site deliveries through our use of offsite, saving 10 tonnes of carbon. The new £14 m energy centre we designed, manufactured, and installed, is also more reliable, and utilises modern and more efficient plant and equipment, reducing the Trust’s future energy consumption and carbon footprint. This one example

At the University Hospital of North Tees’ new £14 million energy centre, NG Bailey was able to eliminate over 6,000 labour hours and 180 site deliveries through use of offsite, saving 10 tonnes of carbon. Utilising more reliable, modern, and more efficient plant and equipment, the new energy centre should reduce both the Trust’s future energy consumption and carbon footprint.
