Over the next several years, Howe's business expanded into engineering consulting and, much more profitably, general contracting.[16] His firm came to dominate the construction of grain elevators in the West, as the Saskatchewan and Alberta wheat pools gave him much of their construction business. This made him unpopular among private wheat companies: his firm did not receive any contracts to build terminal elevators for private corporations in the 1920s, but exceeded the number built by all other contractors combined, thanks to business from those cooperatives.[17] Howe's elevators were built more quickly, were better designed, and were cheaper to construct than those of his competitors. He worked to add to their efficiency; the Dominion-Howe unloader he helped design emptied a grain car in eight minutes, needing only two operators; the same operation had previously taken an hour for a crew of 20 men.[18]
