Onshore Wind Farms Across Terrains

With +30 years of experience in onshore wind civil works, we handle tree clearing, site preparation, roads, crane hardstands, foundations, and cable laying. Our expertise ensures efficient and reliable execution, supporting successful wind farm development across various terrains.

Tree clearing: Forest clearing in connection with the establishment of roads, crane sites, and sites for wind farms. The work is carried out by competent and locally based logging companies.

Site facilities: SIC establishes and manages site facilities according to customer requirements, including compounds, heating, and electricity at the site. Up to you if you prefer us to operate from individually owned compounds or shared facilities for contractors and suppliers, ensuring efficient project execution.

Roads & crane hardstand: Tailored to customer specifications we design and construct roads for transporting concrete and wind turbine components. Additionally, we provide solutions for crane foundations, enhancing the safe and effective handling of heavy materials on construction sites.

Foundations: SIC specializes in establishing various types of wind turbine foundations. We design solutions based on provided drawings or offer alternative foundation designs from scratch, aiming to optimize material usage.

Laying cables: In collaboration with our competent subcontractors, SIC lays cables and installs ducts for power cables and optical fibers, ensuring reliable connectivity for wind farms.

Gravity Base Foundation

With SIC you get a partner specialized in gravity base foundations for wind turbines, offering both standard and customized solutions. Whether working from provided designs or optimizing them for better material efficiency, we ensure structurally sound and cost-effective foundations tailored to each project.

Rock-Anchored Foundations

For projects on rocky terrain, SIC has extensive experience in rock-anchored foundations, including traditional bedrock-anchored solutions with line anchors. We also install RockAdapter foundations, ensuring stability and durability even in demanding ground conditions.

Pile Foundation

For projects in watery areas or with soft soil conditions, where traditional foundations are not feasible, SIC construct pile foundations. By driving or drilling piles deep into the ground, the structure is anchored to a stable layer, ensuring durability and load-bearing capacity.

onshore wind project FAQs

- common questions about our onshore wind projects -

To SIC safety is an integrated part of execution – not a parallel process. Planning  plays a key role. Work sequences are structured to avoid unnecessary overlap between high-risk activities, and risk assessments are continuously updated as conditions change – whether that’s ground conditions, weather or site congestion.

 

Unexpected issues – whether related to soil, access, or design – are inevitable. The key is having decision-making close to site and maintaining flexibility in planning and sequencing.

Wind projects often involve multiple contractors working in parallel. We focus on clear interface definitions, shared planning, and ongoing coordination to avoid clashes – especially between civil, electrical, and turbine installation teams.

Our teams coordinate closely with engineers, electrical contractors, and other project partners to ensure that the civil works are delivered according to the project design and timeline. This integrated approach helps ensure that the infrastructure is ready for electrical installation and that the different project phases connect smoothly.

We combine local subcontractors with our own management and technical supervision. This ensures local knowledge is used effectively while maintaining consistent standards across the project.

It also ensures that we become closer with the local community and bring value in other ways than the project alone.

We plan site layout and logistics flows early, including material storage, transport routes, and work zones. This becomes critical on constrained sites or where multiple activities happen simultaneously.

It largely comes down to people, structure, and communication on site. We prioritize having experienced crews who are properly trained and familiar with the standards and workflows before work starts.

At the same time, we keep decision-making close to site. That means a tight organization with short lines of communication between supervisors, engineers, and project management – supported by frequent coordination meetings to track progress and address issues early.

Delays are often linked to ground conditions, weather, or poor coordination between disciplines. Addressing these early and maintaining flexibility in execution is key.
