Michels Canada has constructed 22 km of 42 in. natural gas pipeline and associated fabricated facilities on the Rocky View section of the Western Alberta System mainline loop, Alberta, Canada.
The work site was a combination of rural and urban locations that intersected the town of Cochrane and surrounding Rocky View County in Alberta's foothills region. Crews worked around scattered wetlands and a key wildlife biodiversity zone along the construction footprint associated with the Bow and Elbow Rivers.
Construction on the two-year project was completed in October 2020.
The project used mainly conventional pipeline construction techniques with the pipe placed 1.2 m (4 ft) below grade in an urban area. Two sections were completed by Horizontal Directional Drilling (HDD). One 650 m (2132 ft) crossing under the planned Springbank Reservoir was approximately 32 m below grade and 17.5 m below the bottom of the proposed reservoir channel. The second 1040 m (3412 ft) crossing under the Bow River was approximately 51 m beneath the river bottom.
During peak production, approximately 600 people were involved in construction. Due to native grasses and other environmental concerns, crews installed wooden access mats along extensive sections of right-of-way to facilitate the movement of heavy construction equipment. A sound wall was installed on the entry side of the Bow River HDD to mitigate noise for nearby residents.
