Moray East Substation Platform

Enabling infrastructure for a major new substation.

The Moray East project forms part of the onshore enabling works package for the offshore Moray East Windfarm, which will generate 950MW of power to the national grid via a 52km offshore and 34km onshore cable route to this new substation.

Employed by principal contractor Siemens, our works required the construction of substantial temporary and permanent compounds, earthworks, 500m of access roads, road and platform drainage, as well as six temporary construction lagoons.

Key Challenges.

To construct the main substation platform, we were tasked with the excavation of 120,000m3 of weathered and dolomite rock. This process utilised both our in-house operatives and plant, before crushing the material as part of our cut-to-fill operation that would create the final platform.

An additional challenge was the presence of live overhead high voltage power lines situated adjacent to the site. Through extensive liaison, careful planning, and full supervision, this obstacle did not hinder successful completion of the earthworks.

Once the earthworks were completed, a process of settlement monitoring was undertaken to ensure that the platform remained within tolerance during the substation commissioning phase.

Our Solution.

We were tasked with the design of temporary works for the whole of the ‘Contractors Works’ package which included surface water management, fencing, materials and stockpile management, temporary site establishment, and construction haul roads.
