Ash Tunnel Modifications

Mining & Metals


The underground firewater piping system at a client’s mine south of Lake Wabamun, Alberta, had corroded and required replacement. ONEC was contracted to engineer and replace the underground system with new HDPE piping, hydrants, and post indicator valves. This project had road crossings and over 100 piping and electrical crossings to be managed by our construction teams.

Tank Farm Expansion

Power & Utilties


ONEC provided full engineering, procurement, and construction services for a tank farm expansion at a pharmaceutical facility in Edmonton. The client initially came to ONEC for a study as we had both designed and installed the previous tank farm expansion at the site. This project included four 50,000L, 316SS solvent tanks, loading/unloading facilities, pumps, metering, feed vessels, and filtering systems. Our team produced all engineering deliverables, procured equipment and bulk materials/tanks, and performed the construction.

Oil & Gas


In order to increase the incoming shipper capacity to a terminal, the client installed a new piperack to a meter bank. This pipe rack was intended convey new delivery lines from various facilities with an ultimate buildout for two additional rack tiers and structural capacity for numerous future incoming shipper pipelines. A multitude of existing underground pipelines are located north of the existing east-west pipe rack within the new proposed rack alignment. To facilitate installation of the new pipe rack, two existing underground pipelines needed to be removed.
