Electronet subcontracted the civil works to Martin Civil Construction due to the team’s expertise working within the electrical environment. The upgrade included: Two yard extensions totaling to 1087m2 with 90m of new substation fence, the construction of 2 new transformer foundations and associated auxiliary foundations incl ducting, demolition of existing transformer foundations, The upgrade of the existing oil containment system and associated drainage and a new control building basement floor to prevent dampness.

 

Martin Civil Construction undertook

    • Construction of 16 new foundations under live buswork
    • Demolition of existing transformer foundations
    • Oil containment system upgrade outside of yard involving excavation, shields and construction of a new SEPA unit foundation

    • Excavation and installation of 13m of pre-cast trenches supplied by our pre-cast team
    • Transformer drainage installation – 55m of 100mm PE pipe welded and installed by our drainage team

 

Key challenges

    • Weather in Stoke – team worked through hot weather in order to stick to project timeline for client. Invested in cooler overalls for the team
    • This project continued through Covid-19 lockdown. A dedicated team worked closely with MCC’s H&S Officer to create safe working procedure to allow the essential works on the oil containment system to continue
