Introduction to GOSH

Great Ormond Street Hospital (GOSH) is an international centre of excellence in child healthcare. Since its formation in 1852, the hospital has been dedicated to children’s healthcare and finding new and better ways to treat child illnesses. Quinn London have been working with GOSH since 2018 and has completed several fast track projects within the live hospital, at all times putting the hospital, patients and stakeholders first.

Overview of the project

GOSH appointed Quinn London to carry out refurbishment and fit out works to create a Medical Equipment Decontamination Unit (MEDU). The MEDU is the first of its kind in the UK and sets a benchmark for other trusts to follow in the future. The decontamination unit uses a hydrogen peroxide vapour to decontaminate medical equipment so that it is quickly sterilised for use.

The contract involved fit out works to an existing storeroom to create a compliant environment for the decontamination of medical equipment that has clear segregation of dirty and clean equipment. The works began with the initial strip out and demolition of walls and an existing staircase. We extended the existing footprint of the building with installation of block work and a roof membrane to protect both the inbound ‘dirty’ corridor and outbound ‘clean’ corridor. Once structural changes had been completed, we installed partitions to create the new layout and completed the 1st and 2nd fix of the M&E system and flooring installation. This was followed by installing automatic sliding doors, Altro Whiterock finishes to all walls and the FF&E, all of which were HTM compliant.

We carefully segregated the works throughout the duration of the project to ensure the safety of the staff and hospital stakeholders and to avoid any spread of dust or debris.

Overview of Project challenges

A main part of the project involved the design, supply, and installation of the fogging room, which is used to decontaminate medical equipment. The fogging machine specified could not interface with the existing external controls systems or with other equipment such as the doors or ventilation system. This proved to be a key challenge because the fogging process is very harmful and dangerous, hence the requirement for a 100% gas tight room. Without the option for the fogging machine to interface with the equipment (which would have allowed it to be programmed not to run until the room was 100% gas tight) we were left with an issue.

In order to design a safe system that ensured the fogging room was 100% sealed prior to and during the fogging process, we designed a bespoke controls system and a bespoke user instruction manual to make the process as safe and as automated as possible. This created a system that was clear for users to understand and safe to operate.

The project was completed on time, GOSH appreciated our hands on approach to solving problems and also the amount of effort we put into get projects delivered on time by increasing labour, working longer hours and over weekends to accommodate the design changes made throughout the project.
