Tewksbury GIS Substation Rebuild

This live substation expansion project included several scopes of work to accommodate the expansion of the GIS system and a new emergency generator. Our work included both vacuum and conventional excavation for installation of grounding grid, concrete encased ductbanks as well as Trenwa trench. We also self-performed the installation of cast-in-place concrete foundations.
