Shet £7.4bn civils and transmission framework: delivery notes for project engineers

First reported on New Civil Engineer
30 Second Briefing
Scottish Hydro Electric Transmission has launched a £7.4bn multi-lot framework covering civil engineering, buildings, overhead line (OHL) and underground cable (UGC) works across its Scottish transmission network investment programme. The framework will bundle large substation platforms, foundations, access roads and control buildings with new high-voltage OHL routes and UGC sections to support grid reinforcement and connection of new generation. Contractors can expect long-duration workbanks, complex geotechnical conditions in upland and coastal corridors, and tight delivery interfaces between civils, structural and electrical packages.
Technical Brief
- Framework value is £7.4bn, giving multi-year visibility for civils and transmission contractors’ workbanks.
- Scottish Hydro Electric Transmission (Shet) is the single client entity procuring all framework lots.
- Scope explicitly spans civil engineering, buildings, overhead line (OHL) and underground cable (UGC) delivery packages.
- Contracting parties will interface with Shet’s wider transmission investment programme, not stand-alone projects.
- Long-duration framework suggests emphasis on standardised design details and repeatable construction methodologies.
Our Take
Within our 861 Infrastructure stories, Scotland has relatively few multi‑billion‑pound frameworks, so this Scottish Hydro Electric Transmission programme is likely to set reference pricing and contract structures for other UK grid and civils procurements.
The related Shetland subsea fixed link study involving LNS, BeMo and Strabag suggests that northern Scottish authorities are simultaneously scoping both major transmission and transport corridors, which could create overlapping demand for tunnelling, marine works and remote‑area logistics expertise.
For contractors, a long‑horizon framework of this scale in the United Kingdom typically favours teams that can demonstrate repeatable delivery in harsh coastal and island environments, an area where firms active in the Shetland fixed‑link evaluations may have a competitive narrative.
