The Brief

Freedom were asked to provide a flood defence solution for an NPG Distributions substation consisting of two 132/25Kv transformers. The substation was built in the 1960’s and had extensive ducts built into the base of the building that would potentially allow flood waters or raised water table levels to enter into the control room.

The Approach

This was a primary substation with over sailing cables as well as buried HV cables. The project was partially carried out in the winter, the team produced inventive ways to speed up the project so as not to let the project run further into the winter. As the project was a design and build, the team helped designers come up with quicker and less expensive ways to create the design objective such as Pitchmasticing buildings and fitting flood doors.

The Delivery

Freedom delivered quality solutions ahead of schedule saving the client money. Site challenges were considered by the engineering team who on all occasions through this project, studied the best possible workable, value engineered solutions. These were then added to the construction drawings and put into action by the site team, saving the client time and money.
