Residential contractors and land developers face much risk during the course of their projects. New construction often conflicts with the various unknowns beneath the surface, specifically utilities such as; existing gas, hydro, electrical, telecommunications, water and sewer infrastructure.

When the State of Washington implemented damage prevention legislation, the hardest part for the departments and organizations involved was determining how that legislation would be enforced. They wanted a system that helped to change people’s behaviour around buried utilities, to prevent lines from getting cut, but they wanted it focused education, rather than penalties—and above all they wanted to ensure there was no fiscal impact on taxpayers.

In the lead-up to National Skilled Trades and Technology Week, Stephen Lecce, Minister of Education, announced a record-level investment to support expansion of the province's Specialist High Skills Major (SHSM) program to include an additional 122 new programs aimed at encouraging more high school students to enter the skilled trades. It is estimated that by 2021, one in five new jobs in Ontario will be in trades-related occupations, with employers already facing a shortage of workers in key sectors.



With household waste, unwanted possessions and garbage are stuffed into the bin, brought to the curb, and promptly forgotten about. However, behind the scenes, there’s an army of city employees working to transport, sort, and store the waste. This process works perfectly on a small scale, but what if the project is bigger? What if, instead of a bag of garbage, the material in question was truckloads of dirt?

On Tuesday, August 13, a 6.8 m (22.3 ft) diameter Robbins Single Shield TBM accomplished an epic feat of tunneling. The unique TBM, designed to statically hold up to 20 bar pressure, had bored below the Hudson River for 3,794 m (12,448 ft) over 582 days with instantaneous penetration rates of 6 m (20 ft) per hour. The tunnel depth was a challenge, ranging from nearly 270 m (900 ft) deep where the TBM was launched in Newburgh, New York to over 180 m (600 ft) deep at the exit shaft. The water volume and pressure were also challenges.
