University Hospital Lewisham

Share on

Bouygues Energies & Services (Bouygues E&S) partnered with University Hospital Lewisham (UHL) in 2016 under a 20-year PFI agreement to deliver Hard Facilities Management services. The work we do supports the UHL in delivering the highest standard of healthcare to the community.
The Hard Services that we deliver are within the Riverside building; a 22,000m2 building that contains 415 beds over 6 floors and includes intensive care, high dependency and cardiology units.


of building managed



UHL required a seamless transition from the previous contractor, overcoming the inherent challenges and transferring staff efficiently and effectively. A flexible partnership with UHL was needed to ensure that their standards were maintained and demonstrated throughout the building, to patients and users.

Our Solution

Through collaboration with UHL, we have successfully achieved their requirements on an ongoing basis. We have engaged in regular communication with the UHL team and other service providers, adopting a ‘one team’ approach that is maintained across the estate. We have open communication with the teams to address any issues, allowing innovative solutions to be developed.

Working closely with our Special Purpose Vehicle team, we have ensured that lifecycle requirements are met professionally and in accordance with the contract, benefiting all parties in service delivery and ensuring a comfortable patient experience.

The creation of Authorised Person/Competent Person & Authorising Engineer roles has also proved successful, with a full support system that can provide major planning and orchestration of critical system works. In order to remain a flexible partnership, Bouygues E&S began providing Grounds Maintenance service for the client in 2017, which is within the main body of our approach.

Client Benefits

  • Working as one team with other service providers has provided a greater understanding of all components that operate within the hospital environment.
  • Utilising Bouygues E&S Energy team to assist in energy management along with environmental impact reduction.
  • Joint communication with the UHL’s Health & Safety department and Bouygues E&S QSE advisers to develop a collaborative approach between these departments.
  • UHL benefits from access to all BYES specialist departments to provide expertise in a particular fields

Broomfield Hospital

Share on

Bouygues Energies & Services has been working in partnership with the Broomfield Hospital to deliver Hard FM, Lifecycle and HelpDesk Services to the New Build element since 2010.


Statutory compliance

Working closely with our client, we work hard to ensure the building and services continue to meet the demanding and critical nature of patient care. We put the patient experience first, providing a well maintained, fully compliant hospital environment. By ensuring we keep the patients at the forefront of our minds, we have built a strong relationship with our client based on trust and hard work.

Our Solution

It was fundamental for Broomfield Hospital, and Bouygues E&S, that the patient experience was not impacted by the dual approach to Hard FM services, and that service remained consistent across the hospital.

As part of our service delivery platform, we established a HelpDesk facility that deals with all Hard and Soft FM Services in one central place.

The creation of interfaces and protocols detailing responsibilities on site (including AE/AP roles), in relation to shared technology such as fire systems, pneumatic tubes and physical links between the new and retained estate has been fundamental to our success on this project.

Our approach improved the hospital’s reporting mechanisms, aligned the facilities under a single number and provided added value through the removal of dual running costs.

Working with Broomfield Hospital, we ensure that we always maintain consistency of service for the teams and patients regardless of the building category or whoever is delivering the services.

Client Benefits

Joint procurement approach

By working together with the hospital, we can benchmark subcontractor prices and therefore procure at the best price for our client.

Collaborative benchmarking

By conducting bottom-up reviews of Hard FM services costs with the client and external advisers (costs identified as within benchmarks) during operations, we continually challenge and optimise the services we are providing.

Corporate Responsibility

In line with our corporate approach, we currently use 67% SMEs in our supply chain.

We actively seek to recruit from the local community and have an apprenticeship scheme in place to support those getting into work.

Silver Hydrocel and Tank Farm Capacity Increase

Share on

Our client required the modification of their facility, where they chemically convert cellulose based fibres into a gelling fibre for antimicrobial wound dressings which contain ionic silver. Such products are registered as Class III medical devices, so the facility is required to operate under cGMP guidelines and is auditable by BSi, FDA and MHRA. 

Grade D



temperature control


tonnes/year output

They required the capacity increase of a Silver Hydrocel manufacturing suite and an additional Industrial Denatured Alcohol (IDA) and Solvent Effluent storage capacity increase, that could be integrated with minimal disruption to ongoing operations. The capacity increase needed to include provision of Grade D cleanrooms fitted-out with manufacturing equipment, all of which would be designed, commissioned and validated in compliance with corporate and regulatory standards.

Our Solution

Bouygues Energies & Services were required to adopt the design for the facility in its current form and complete the necessary detail to facilitate two operational suites, supporting facilities, utilities, services and equipment within the annex building.

The Grade D suites were provided with a discreet HVAC system, comprising of air handling units and extract fans to allow independent operation. The air flows were designed to achieve a minimum air change rate of 20 per hour and the technical spaces are served by natural ventilation.

Room pressures were designed to maintain GMP and solvent vapour containment requirements; pressure differentials can be monitored and an alarm is raised if an area does not retain pressure within a specified delay time. Temperature can also be controlled to 21±3.

Our solution included chemical storage and distribution systems capable of handling industrial denatured alcohol (IDA), silver nitrate, brine, BeCl and Tween. Presence of IDA was a particular challenge, as it is a highly flammable liquid. A range of measures were put in place to reduce risk of fire or explosion, adhering to DSEAR and ATEX 137 regulations.

Client Benefits

Providing Medical Devices (EBME) Maintenance

Share on

Existing healthcare clients of Bouygues Energies & Services were uncertain of the compliance rate of their clinical engineering/Electro-Bio Medical Equipment (EBME). With planned CQC inspections approaching, the clients wanted to know what was required to bring their device inventories to 100% compliance.



compliance from the measured rate of 32%


interference with clinical operations

We were already providing hard facilities management services for our clients and were able to enhance this service through our expertise in low and medium risk medical device maintenance.

Our Solution

Detailed audits were performed on existing policies, processes, structure and records. A key challenge was showing the clinical engineering departments that the audit highlighted where we could provide additional support, and assist them with the CQC audit. The findings were then discussed in confidence with the clients, before submitting to the board.

We created a solution to bring the compliance rate back up to 100%. This involved targeting product families and then expanding through areas to obtain final completion sign off. By working closely with our EBME partners, we put together a detailed schedule of works to achieve 100% compliance.

Communication was essential to the client and this was maintained through weekly reports on the progress.

Additional services we offer are:

  • Combining the clinical device helpdesk with the hard FM helpdesk; logging all reactive jobs against the particular device
  • Providing and implementing a 53-week (PPM) planner
  • Maintaining device databases
  • Procurement of new devices when necessary and disposal of failed and redundant devices

Client Benefits

With detailed preparation, a small team of specialist engineers were able to begin promptly, and over an 11-week period provided documented proof of 100% compliance. A total of over 5,000 devices were tested and signed off across 58 different wards / departments.
