en.Wedoany.com Reported - Scottish Hydro Electric Transmission issued a tender notice on June 3, launching a nationwide framework agreement worth up to £7.4 billion, covering engineering fields such as civil works, buildings, overhead lines, and underground cables.
The electricity supplier is seeking long-term strategic partners to undertake tasks including design, management, construction, testing, and commissioning. The tendering party stated that contracted contractors will participate in grid upgrades, asset renewal, user connections, and net-zero infrastructure construction. The framework plan includes six lots with a maximum contract duration of eight years. Scottish Hydro Electric Transmission stated that this procurement will support projects within its large capital delivery portfolio.
The civil engineering lot is divided into two categories based on project value: below £10 million and above £10 million. The low-value civil engineering lot involves substation earthworks, access roads, drainage systems, pipeline laying, fence installation, and environmental mitigation works, tendered separately across five geographical regions in Scotland. The high-value civil engineering lot covers more complex schemes, including bridge refurbishment, retaining wall reinforcement, culvert construction, flood defense works, major road diversions, peatland ecological restoration, and operations integrated with in-service transmission assets.
The buildings and infrastructure lot covers new construction projects such as office buildings, training centers, dormitories, welfare facilities, as well as renovation, expansion, and mechanical and electrical (M&E) fit-outs. The scope of work for this lot also includes design management, planning approvals, building information modeling (BIM) application, environmental assessments, and, where necessary, replacement of roof structures constructed from reinforced autoclaved aerated concrete (RAAC).
Overhead lines are split into two separate lots. The pole construction lot focuses on 132kV transmission line works, including foundation construction, pole erection, conductor installation, and substation connections. The tower construction lot targets lattice tower projects using voltage levels such as 132kV, 275kV, and 400kV, with work including foundation construction, steel structure erection, and transmission line diversions.
The final lot covers underground cable construction for transmission projects at 132kV and above, encompassing route design, trench excavation, duct laying, joint bay creation, cable installation, site restoration, and commissioning support. This tender adopts a competitive procedure with negotiation, with the deadline for submission of expressions of interest set for July 16.
