Suncor Refinery

Our BTrenchless division was contracted by Suncor Refinery to install 500 LF 72" Microtunnel underneath two railroad tracks and a state highway. This tunnel connected each side of the plant with new gas and system lines. This project involved constructing two 20' deep entry and exit pits in a confined layout inside the refinery facility with very tight safety requirements and unusual hazards.
