New win: 33kV cable infrastructure in Scotland
Rospower Projects has secured a 33kV cable civils scheme in Scotland: 4 km of route across agricultural land and carriageway, through to reinstatement.
By Connor Lyons, Commercial director, MRICS
Rospower Projects has been appointed to deliver civil works for a 33 kV cable infrastructure scheme in Scotland. The route covers 4 km, comprising 1.5 km of agricultural land and 2.5 km of carriageway.
The civils package extends beyond trench excavation, covering duct installation, protective surround, backfilling and permanent reinstatement across agricultural land and carriageway. It is a new appointment, with route preparation and coordination of those stages central to the work ahead.
The scheme at a glance
| Item | Confirmed scope |
|---|---|
| Scheme | 33 kV cable infrastructure |
| Location | Scotland |
| Agricultural land | 1.5 km of route |
| Carriageway | 2.5 km of route |
| Total route | 4 km |
| Civil works | Route preparation, trenching, duct installation, protection, backfilling and permanent reinstatement |
The length describes the route through those two working environments, not the combined length of individual cables or ducts.
From route checks to permanent reinstatement
The package follows an engineering sequence:
- Prepare the route. Trial holes and route-feasibility assessment inform the work before the main trench excavation.
- Install and protect the infrastructure. Duct installation is followed by the specified surround, protective tape or tiles, and backfilling. The project design determines the arrangement and materials required.
- Reinstate the surface. Permanent reinstatement completes the civil works, with separate requirements for agricultural ground and carriageway.
The sequence links the work below ground to the condition of the land and road surface handed back after construction.
Planning for agricultural land and carriageway
The two route sections bring different access considerations. On agricultural ground, planning needs to address access to the work area. In the carriageway, the sequence also needs to account for road users. The project-specific design and agreed arrangements will determine the detail.
Safe excavation is part of that planning. The HSE’s HSG47 guidance on avoiding danger from underground services identifies three elements of a safe system of work: planning, locating and identifying buried services, and safe excavation. This guidance provides the general safety context for the route preparation and excavation stages.
More about our connection civils work
Our electricity connection civil works service covers cable trenching, ducting, joint bays, substation bases and reinstatement, with the package and responsibilities agreed for each project.
For examples of completed work, our separate LV network projects at Anstey Lane in Alton and Aycliffe Road in Borehamwood show cable route excavation and reinstatement in existing streets. Their project pages contain photographs of those completed jobs.
If you are preparing a cable civils package, send us the route drawings, scope and programme or contact Rospower Projects to discuss the work.
