Jastrowie-Okonek Wind Farm
Client: Amazon/Votrex/P&Q
Turbine types:
12 turbines

• Nordex N149 5.0 MW TS105
• Nordex N131/3600 TS99
• Nordex N149 5.0 MW TS125
• Nordex N131/3900 TS84

Scope of services:

• Foundation design.
• Geotechnical design.
• Ground improvement works on site.
• Cost optimisation through technology:
  • Variety of turbines: Four different types of turbines used on the farm.
  • Diversity of foundations: Six different foundation types on one wind farm site.

• Key to cost optimisation:
  • The use of a combination of ground improvement technologies has resulted in an optimum return on investment, including: 
    • CFA
    • FDC
    • Driven Piles – piling with a piling machine

Additional customer value: 

• Lower construction costs: achieved through the optimal choice of foundation technology.
• No technology selection bias: technology neutrality in the choice of solutions, leading to more cost-effective options.

By consolidating the project under one General Contractor, the client gained:

• Additional savings: reduction in project implementation costs.
• Faster construction process: speeding up project delivery.
• Lower risk: reducing the risks arising from coordinating multiple contractors.
• Consolidated responsibility: eliminating the dispersion of responsibility between different actors, which facilitated coordination.
• Higher safety: better safety management thanks to a uniform organisation of project conduct.

This case study illustrates how a combination of modern technology and effective project management has achieved significant savings, increased safety and accelerated project delivery.

Banie Wind Farm
Client: PBE Elbud/ Energix
Turbine type:16 turbines Vestas V126-3.5MW HH137m

Scope of services

• Complex structural design for 16 turbines

Foundation design:

• Geotechnical design.
• Soil improvement works: FDC concrete columns and CFA piles.

Added value: We respond quickly to our customers’ challenges. When faced with difficulties in meeting the investment schedule, we were asked to intervene immediately to accelerate the piling works. Our solution? Organizing and providing additional machinery on-site, enabling the work to be completed faster than expected. This demonstrates our readiness to act and our ability to adapt to dynamic project conditions.
