The Twinning of the Etobicoke Creek Sanitary Sewer involved the microtunneling construction of approximately 576 m of 1,800 mm internal diameter trunk sanitary sewer underneath runways and taxiways at the Lester B. Pearson International. Airport (LBPIA).
The new sewer, runs parallel with the existing sewer to increase capacity and allow for redundancy, diversion and inspection.
A casing for a water main was needed underneath the Mary Hill Bypass to expand service to the metropolitan Vancouver area. Michels combined proper planning, procedures, and execution to overcome issues and turn an uncertain project into a success.
BC Hydro’s John Hart Generating Station has been supplying water for electrical power operation since 1947.
To provide safer, efficient and more reliable service, BC Hydro embarked on the construction of a new underground hydro power generation facility slated for completion in 2018. The change required the City of Campbell River to devise an independent means for sourcing its drinking water.
Presented an opportunity to embark bravely into the next frontier of microtunneling by designing and completing a curved drive, trenchless contractor Super Excavators, Inc. (SEI) stepped up to the challenge, delivering excellent value to the project owner, while working to minimize surface disruption for residents in a busy east side Cleveland neighborhood.
The PWI was a multi-year project that consists of 13 miles of large diameter pipeline constructed from Valley View Boulevard and Serene Avenue in the southwest valley to Nellis Boulevard and Flamingo Road in the southeast valley. The project alignment is generally southwest to northeast in the area to south of the Strip and McCarran Airport.
The King Street Feedermain project included the construction of 852 m of 1200 mm ID RCP water main through the congested downtown of Bolton. Microtunneling was selected as the preferred method, with minimal access shafts to protect the historical integrity of the region while improving their water systems.
The project involves the construction of two force mains and a gravity sewer, a new wet weather pump station and upgrade to an existing pump station to increase capacity and reduce an annual estimate of 13-million gallons of raw sewage discharge into the Cuyahoga River.
The City of Memphis needed to replace the deteriorating triple-barrel siphons under the Wolf River, to help prevent any disruptions. The siphons were past their life cycle being that they were constructed in 1958 and connected to an 84-in concrete interceptor tunnel.
As part of the Destination Medical Center Project (DMC), the Rochester Public Works Department needed to improve a sanitary sewer along 1st Avenue SE to 2nd Street SE, the storm sewer along 2nd Street SE to 3rd Avenue SE, as well as a new siphon located from the 3rd Avenue SE Bridge from the Rochester -Olmsted Government Center to 2nd Street. The packaged result was the 1st Avenue SE Relief Sewer for the Government Siphon J7825 Project.
The expansion of the Port Mann Bridge to a 10-lane structure, widening Highway 1, and upgrading the interchanges were made to reduce the area’s traffic congestion and improve air quality in the Vancouver area. This involved the installation of three large-diameter drainage culverts under Highway 1, which benefited the Latimer Creek and Leoran Brook Salmon Habitat Enhancement Culverts project and satisfied one of the Port Mann/Highway 1 Improvement (PMH1) goals, to protect and improve fish passage between habitats.
