The challenge on this project was:

• To provide a new 550m² extension to an existing enhanced Category 3 high security containments facility.
• To provide a containment facility with a pressure cascade from -20 Pa to -60 Pa.
• Work closely with The Institute’s scientists and engineers to develop a unique solution that enables The Institute to conduct specific research into the airborne transmission of pathogens.
• To provide systems that allow the efficient isolation and fumigation of individual rooms.
• To provide an environment that is conductive to the occupant’s welfare.

Austin’s solution was to ensure containment could be maintained, the facility was constructed from reinforced concrete and all services designed to be automatically isolated and accessed for maintenance from a first floor plant room.

Develop a unique ventilation system that, in conjunction with bespoke air transfer grilles, creates a movement of air between pairs of rooms, but prevents possible cross contamination by other substances.  The ventilation system can be automatically switched between this mode of operation and a normal mode that provides individually ventilated rooms.

Design a ventilation system that allows each room to be remotely isolated so that fumigation of individual rooms can take place.

In line with the Home Office requirements, the facility was designed with tight temperature and humidity control, a bright, well lit environment and finishes that are designed to be easily cleaned.

As the extension increased the total size of the facility, the Institute’s existing Effluent Sterilization facility was also increased to handle the increased facility.  This involved controlled “break-ins” to the existing Category 3 drains.

Austin provided concept design, preliminary engineering, detailed engineering, procurement, project management, construction and commissioning services.  Austin also managed the testing process that enabled the facility to be approved for use by the Home Office.
