Working with utility companies

We have been working alongside major utility companies, such as SSE and SGN since our formation, to deliver the construction of new substations, internal fit outs, refurbishment or extension of existing substations, and general civil engineering works.

We deliver a wide variety of building and civil engineering works including:

  • Ground works
  • Construction of concrete access roads
  • Construction of transformer & cooler bunds
  • Excavation for and construction of concrete bases for electrical equipment
  • Building typical traditional masonry block & brick switch houses with reinforced concrete cable basements and steel sheet roofing, or elevated switch house buildings with walls and roof constructed of composite steel cladding.
  • Installation of concrete cable troughs and ducting
  • Provision and repair of drainage and the laying of compacted stone surfacing.
