SPECIALIST INFRASTRUCTURE CONTRACTOR
Built for Power & Civil Infrastructure
Woodbridge Infrastructure is a specialist UK contractor for power and complex civil infrastructure. We support developers, utilities, ICPs, EPC contractors and principal contractors from early feasibility through to delivery.
Our involvement can begin long before construction.
Through early contractor engagement, grid connection feasibility, site investigations, constructability reviews, programme development and cost planning, Woodbridge helps clients identify practical construction solutions before designs become fixed.
EXPERIENCE AT TRANSMISSION SCALE
HV infrastructure experience up to 400kV.
Woodbridge teams have experience delivering civil engineering associated with major 400kV and 275kV energy infrastructure projects across the UK.

EARLY CONTRACTOR INVOLVEMENT
Buildability Starts Before Construction.
Many of the largest risks associated with an HV grid connection are created before construction begins. Woodbridge provides practical civil engineering input during development and design to help identify these issues early.
Route Strategy
Grid connection feasibility, route optioneering, desktop assessment and site walkovers.
Buildability
Constructability reviews, utility constraints, crossings and temporary works strategy.
Planning
Programme development, preliminary methodology, risk identification and cost planning.
Identify the problems before they become construction problems.
Explore Grid Connection Feasibility
PLAN. SOLVE. DELIVER.
Understand the route. Engineer around the constraints. Deliver the works.
PLAN
Grid Connection Feasibility
Route assessment, constraints, buildability, methodology, programme and budget.
SOLVE
Specialist Engineering
Practical solutions for HDDs, crossings, deep excavations, temporary works and restricted corridors.
DELIVER
HV Infrastructure Construction
Major cable routes, substations, BESS infrastructure and associated civil engineering with project experience up to 400kV.
CORE CAPABILITIES
Infrastructure Capability Across Complex Networks.
Pre-Construction & Feasibility
Early route assessment, constructability, investigation, programme, cost and methodology support.
HV Cable Routes
Open-cut excavation, duct systems, concrete encasement, joint bays, crossings, backfill and reinstatement.
Substation Civils
Earthworks, reinforced concrete, foundations, roads, drainage, cable infrastructure and associated civils.
BESS Infrastructure
Civil engineering supporting utility-scale battery storage developments and grid connections.
Cable Infrastructure
Cable route preparation, duct proving, joint bays, pulling support and associated civil engineering.
HDD & Specialist Crossings
Launch and reception pits, enabling works, temporary works and support to trenchless construction.
SPECIALIST ENGINEERING
Engineering Around the Constraints.
Complex grid connections rarely follow a straightforward route. Woodbridge combines construction experience, early planning and specialist delivery methods to overcome the interfaces that can otherwise drive programme, cost and risk.
When the straightforward solution isn’t possible, we develop a buildable one.
Deep Excavations
Joint bays, launch pits, reception pits, chambers and associated temporary works interfaces.
Constrained Working
Narrow corridors, highways, substations, urban environments and restricted-access locations.
Existing Utilities
Congested services, uncertain records, difficult crossing arrangements and live-asset interfaces.
Ground Conditions
Rock, groundwater, unstable ground and contamination that can change the construction methodology.
Temporary Works
Shoring, trench support, excavation stability, working platforms and access arrangements.
Interface Management
Coordination across civils, HDD specialists, cable installers, jointing teams, electrical contractors, utilities and designers.
HDD & TRENCHLESS CROSSINGS
The Civil Engineering Interface Around the Crossing.
Woodbridge plans, coordinates and delivers the complete civil engineering interface surrounding specialist HDD and trenchless works, working with specialist partners where required. We understand how crossings fit into the wider grid-route programme and construction strategy.
