Dunwald & Fleming Enterprises Ltd.

Natural gas distribution work in Alberta needs trenching, utility installation, access, and restoration planned around existing underground infrastructure. Dunwald & Fleming Enterprises Ltd. is a Calgary-based pipeline contractor and underground utility construction team with more than 40 years in Alberta natural gas distribution systems.

We handle mainline integrity digs when buried pipeline assets need exposed access for inspection or repair activity. Civil and earthworks service can include bulk earthworks and access roads, so the site is ready for utility or pipeline tasks before restoration begins.

Reclamation and remediation needs are part of many underground utility projects. Our service scope includes seeding and riparian zone restoration, which helps return disturbed areas after construction or integrity activity.

Custom fabrication adds shop capability when a field project needs built components to match the installation. Since starting in Calgary in 1978, Dunwald & Fleming has also added telecommunication construction for utility corridors and civil infrastructure projects in Alberta.
