Pipeline construction, as anyone who has travelled this province knows, is big business. But are you aware that contractors lay between 12,000 and 15,000 km of pipeline in Alberta, Canada each year?
About 85% of that is pipe less than 12 inches in diameter-in fact, most pipe has a diameter less than six inches. Yet, virtually every installation requires excavating a trench between 32 and 42 inches wide.
