machine advances it spits out the smaller rock fragments and simultaneously installs segmental liner plates. The segmental liner added is a foot thick on the top and bo om, making the nished tunnel hole 10 feet in diameter. The liner locks together like a ve-piece puzzle, making it leak proof.
“The average ci zen won’t know that the TBM is working underground,” said McCarney, adding the machine, which costs in the neighbourhood of $7Million, will be working 22 hours a day, ve days a week. “It will be literally like a mechanical mole working deep in the ground - its a very safe and sophis cated machine.”
One of the biggest challenges for the project, McCarney noted, is ming, especially since the three-year project coincides with O awa 2017, celebra ng Canada’s 150th anniversary. However, the companies have successfully worked together before on major infrastructure projects in the city. “We are very honoured that the Dragados-Tomlinson Joint Venture has been awarded this signi cant infrastructure project here in O awa,” said Ricardo Franco, president of Dragados Canada. “We are aware how important the CSST project is for the city and have con dence that the work our highly quali ed team will deliver will contribute to preserve the O awa River for genera ons to come.”
The Dragados-Tomlinson Joint Venture (DTJV) on the CSST project is a testament to the great work completed by many Tomlinson divisions in the past 4 years on the OLRT Phase 1. Countless nights and weekends worked by crews to deliver new sewers and watermain on schedule, the construc on of the newly widened Highway 417 including many structures and o - ramps – these e orts have built trust with Dragados, a partner of the Rideau Transit Group, who was awarded the $2 Billion Phase 1 of the OLRT. Tomlinson’s Core Value of Excellence has led to the OLRT awarding many follow-up contracts to Tomlinson and ul mately, led to a partnership being formed for the CSST.
The process of being awarded the CSST contract started early in 2015 with the prepara on of the Request for Quali ca ons. DTJV was one of ve successful teams short-listed to begin working on the bid. Adam Hendriks and Darrin Alberty acted as leads for the sewer/watermain works and Mario Lalonde and Derek Conway were principally in charge of the Heavy Civil components. Many others helped behind the scenes with pricing and support and it was truly a team e ort which led to the winning bid on April 26, 2016.
