Medical Air Technology and iSIGHT
A shared vision for upgraded theatre facilities
iSIGHT has always placed great emphasis on the importance of offering its patients the most technologically advanced treatment arena. When ventilation and temperature control in the operating theatre had to be upgraded to bring it in line with the latest standards outlined in HTM 03-01, iSIGHT needed to find a specialist contractor that would be able to
take on this complex project. In initial meetings with the clinic’s owner, consultant ophthalmologist Dr Tayo Akingbehin, MAT was quickly able to demonstrate that it not only had the necessary experience but also an appreciation of the constraints that would surround the work and an understanding of how the new installation could be incorporated within a listed building, proving itself to be the ideal partner
The listing required that no alterations were to be done to the building fabric or structure and that detailed planning permission would be required. Work was complicated further by the fact that the operating theatre is located in a low vaulted basement that lies below the water table. MAT’s scheme of works had to demonstrate strict adherence to the
planning requirements, which was achieved by routing the new ductwork to avoid structural alterations while at the same time maintaining the waterproofing of the basement. Clever planning allowed the air handling unit (AHU) and controls to be installed in an adjacent garage.
“As the practice manager and undertaking such a large project while still serving the patients, I thought it would be a major headache onsite on a daily basis. How wrong I was.
MAT and all contractors employed by them were nothing but professional, mindful of our business, polite and an absolute pleasure to work with.
At each stage of the journey we were kept informed and changes implemented when issues arose. I cannot recommend MAT highly enough.”
Natalie Pepper: Practice Manager, iSIGHT Clinic
As iSIGHT is located in a residential area, it was important to minimise disruption to the surrounding buildings while work was underway and also to ensure that once running, the new plant would not disturb the neighbours or look out of place. Careful planning by MAT and close liaison with the team at iSIGHT meant that everything went smoothly, and there have been no complaints about noise or disruption either during the project or since the new ventilation has been operational.
MAT offers a wide range of services so is able to respond flexibly and quickly to the specific needs of each client, providing all the benefits that come from working with a specialist contractor. With its own in-house UK manufacturing facility and dedicated team of highly skilled engineers, MAT manufactures and supplies bespoke equipment for demanding clinical arenas.
Clients can choose from several options, ranging from ultraclean ventilation (UCV) canopy or theatre ventilation equipment only, right through to a total turnkey package, ensuring they get exactly the solution they need. In addition, MAT FM can provide a range of competitively priced and highly effective service and maintenance packages for all core products and turnkey solutions offered by MAT or other suppliers, ensuring that equipment is maintained, serviced and validated correctly for optimum performance.
After completing several previous cleanroom and containment laboratory projects at Imperial College London, MAT was proud and excited to once again have the opportunity to work in partnership with such a prestigious institution to deliver the new research environments.
After initial designs were developed and approved, building work began in summer 2020 and the new cleanrooms were handed over in June 2021, the entire project having taken just 11 months.
Imperial College London is a global top ten university with a world class reputation. Its alumni include 14 Nobel Prize winners, including Sir Alexander Fleming.
To enable the highest level of research, the university offers the best
possible facilities. One of its flagship buildings is the £90m Sir Michael
Uren Hub, located at the White City campus. Designed as a
collaborative facility, the 13-storey Hub provides space for Imperial’s
world-leading researchers, engineers, scientists and clinicians to work
alongside one another to investigate some of the twenty first century’s
most urgent biomedical and healthcare problems.
FEATURES CONTAINED WITHIN THE CLEANROOMS:
The new cleanrooms MAT was commissioned to design and build both had to be ISO Class 6 standard to safely accommodate the semiconductor research that would be carried out in them. Class 6, as defined in ISO 14644-1:2015 Cleanrooms and Controlled Environments, refers to the cleanliness levels that must be met within the cleanroom.
In addition to having a high air change rate, an ISO 6 environment must be accessed through airlocks to preserve pressurisation differentials and prevent the migration of particles from outside into the cleanroom space, increasing one class at a time. So, users should pass through an ISO 8 environment, then an ISO 7 environment, before entering the ISO 6 cleanroom.
MAT acted as the designer and main contractor on the cleanroom project, working closely with the university to ensure minimum disruption to the other activities being carried out in the Sir Michael Uren Hub.
The team developed a design built around the complex research equipment and specialist tools that would be housed in the new cleanrooms. Work included final services connections and extensive bottled and house gases installation to several hazardous gases and associated gas detection systems.
HVAC design is complex and requires a highly skilled delivery team.
MAT is an expert in the provision of specialist HVAC systems. The HVAC system is at the heart of cleanroom design. Cleanroom HVACs differ from standard systems in that they have an increased air supply, different airflow patterns, use of high efficiency particulate air (HEPA) filters, and room pressurisation, and clean to dirty room air cascades.
In order to meet the required air cleanliness, the air must pass through HEPA filters. The lower the ISO class, the more often the air must pass through the HEPA filter. This ‘air changes per hour’ rate (ACH) and the room volume are used to calculate the HVAC’s required airflow. A conventional HVAC system usually makes two to four air changes per hour, whereas in a cleanroom it can range anywhere from 10 to 250 or even more.
The ISO Class 6 cleanrooms at Imperial College London require air change rates from 50 to 70 per hour.
MAT designs, manufactures and installs bespoke critical ventilation systems and turnkey project solutions for new build and refurbishment projects. As a specialist contractor with many years’ experience, we are passionately committed to improving patient protection and end-user safety in demanding clinical, research and drug production arenas.
We have extensive experience of working in live environments and understand the challenges around delivering a project within an operational scenario.
In addition, MAT FM provides a range of competitively priced and highly effective service and maintenance packages for all core products and turnkey solutions offered by MAT or other suppliers, ensuring that equipment is maintained, serviced and validated correctly for optimum performance.
