The project to bring back long-range radar coverage from the far North of Scotland saw the previously closed Saxa Vord Radar site being regenerated and brought back online.  The site was to be taken back into service as a Remote Radar Head (RRH) which required substantial security and technological upgrades.

Nordri Ltd formed part of the design and delivery team on site as Mechanical and Electrical (M&E) contractor. 

The scope of works required was complex in that it required multi-disciplined input not only from our design and installation team, but from the client, other subcontractors, and specialist manufacturers.  

The works included but not limited to:

• Replace sub-mains underground feed cable.

• Small light and power in new build areas of site.

• Electrical containment and switch gear to allow integration of new equipment.

• Installation of 275KVA genset with associated air, exhaust and fuel supplies.

• Installation of supporting fuel storage.

• Site and build Uninterruptible Power Supply and changeover switches.

• Replace operationally critical LV feeder pillar.

To ensure a successful project delivery, on award of contract works we established a dedicated project team to undertake the works with a single project lead.  Given the sensitivities of working on an operational military site, relevant staff obtained suitable Security Clearance and qualified as Skilled Persons to allow autonomous working in accordance with client, engineering authority and site requirements.

Overall, the project was successfully completed in line with the client’s expectations.  All aspects of the project were tested, commissioned, signed off and brought into service followed by formal handover.  A full suite of project documentation and records along with an Operation and Maintenance Manual were produced.
