crotunnelling and traditional meth- ods. And in 2018, it received the Con- sulting Engineers of Alberta Award of Excellence for the Southwest Water Supply project for the Regional Mu- nicipality of Wood Buffalo for the design of a 1,400 m long , 750-mm diameter, steel pipe HDD crossing of the Athabasca River. GROWTH AHEAD Lueke sees a trend toward larger sized trenchless projects. He says, " In the last five years, we have seen a steady decrease in the number of HDD projects, and a significant up - tick in the number of microtunnel and utility tunnelling work we are doing at Associated Engineering . This trend is in response to the con- fidence in owners and consultants in tunnelling technology, and the grow- ing microtunnelling and tunnelling expertise in the industry. The ben- efits to utility owners are reduced risks, lower construction costs, and less disruption to congested urban areas." " If we look at the future of trench- less work in Canada, we see more tun- nelling . We see significant work and potential in the Greater Toronto Area, Winnipeg , Edmonton and Calgary. From a municipal perspective, we see a greater number of tunnelling proj- ects than directional drilling projects occurring over the near future," says Lueke. Calgary, for example, is heavily in- volved in light rail transit and Associ- ated Engineering is working on light rail projects in Edmonton, and both are part of Canada's push for sustain- able transportation alternatives. Part and parcel with these projects are the associated utility work and when that comes into play, there is definitely room for trenchless to shine. Reflecting on the shift towards more tunnelling projects at Associat- ed Engineering , McDermott says that since he joined the company 10 years ago, he has watched microtunnelling boom in Eastern Canada. " Because the Greater Toronto Area is so built up, we are forced to do more trenchless construction to miti- gate impacts on the public," he says. " In the last 10 years the industry has evolved from hand mining small di- ameter tunnels to microtunnelling , and in the last four to five years mi- crotunnelling technology has really become standard practice for com- plex tunnel drives in adverse ground conditions." He adds that he doesn't see any of this development slowing as more and more projects take place in the Greater Toronto Area. " The industry here is extremely busy and there is more need for trenchless components on every project we design these days based on the ever-expanding growth of the GTA ."
