Case Studies

Here we have some examples of some case studies, of projects that PSL have provided for our clients.

County Hall – New London Dungeon

Case StdiesPipefreezing Services Ltd. was chosen as the supplier of pipe freeze isolation services for the whole project. This project lasted for a duration of several months. Their were plenty of challenges, in particular difficult basement working conditions, lack of electronic communication methods, high  ambient temperatures and limited access.

This project, undertaken by Network Rail was a large scale station redevelopment project spanning platforms, concourses and terminals. This extensive work included the movement, modification and alteration to various mechanical and HVAC systems. Click on Link  Major Rail Station Upgrade

PSL were able to turn this around within days of getting the initial call, turning what could have been over a week of stopped work into just a few days delay.


This is a project was completed for a major school project. It was carried out when a main refurbishment of the school boiler system was undertaken. Please click on the link School_Boilers to find our more about this project and the role we played in rectifying the issues.
