Western General Hospital phase one

Following the successful completion of the Kings Campus project in 2018-2019 in Edinburgh, PPSL were awarded the contract for the first phase of replacing the on site steam network with a new District Heating mains at the Western General hospital.

Weekly design meetings commenced in October 2019 working alongside our customer and the consultant to develop a working design. The route for the district heating mains had to be coordinated with the existing services and also future build plans given the future development results in substantial ground level changes over the next five years, and the introduction of a vast number of future services. PPSL played a key role in coordinating the route and working alongside the numerous stakeholders to create construction drawings as both flat plans and long sections. The design phase was concluded in February 2020 when works commenced on site.

The specified product was Logstor series 2 pipework with diffusion barrier and fusion welded joints. The project also incorporates the installation of a Logstor X1LG alarm panel to continuously monitor the system for potential moisture ingress. This is a key feature of the Logstor steel product. An alarm would be triggered should the pipework be damaged, and one of our alarm engineers can locate the fault to within 1m of it’s location. On sites being heavily developed or at risk of damage from other works this is a valuable addition and can ensure any such faults are repaired swiftly to minimise disruption.

PPSL took responsibility for unloading all the materials utilising a 40 ton mobile crane and contract lift, as well as coordinating the movement of the pipes around site given the challenges of working in a live hospital.

The project was in it’s first month when the Scottish COVID lockdown commenced, which introduced a range of challenges to keeping these essential works on programme.

PPSL’s project team and H&S worked closely with the client to develop a safe working environment that allowed works to continue with the approval of NHS Scotland. Our team ensured H&S and quality was the forefront of the project at all times, and that PPSL’s elements of the works were achieved on time and within budget through what was an extremely busy time for all NHS facilities.

PPSL also undertook all the expansion and contraction design for the project as well as providing all the setting out coordinates for the trenches and pipes throughout the project.

We are fully Accredited

PPSL are proud to hold the following accreditations to demonstrate the high standards we uphold across all our projects




The installation of pre insulated pipess is a more complex process that many other utility services, and primarily undertaken in excavations. The very nature of these working conditions and the products means that upholding and working to audited and approved processes is always essential to ensure the projects we deliver for our clients are the highest industry standards by way of quality and H&S.
