Washington on Hwy 395. It was a ten-million- yard job, and we used them there quite a bit.
“Anybody who’s been around Quads knows that you could sink the can of a scraper down into the ground fourteen to sixteen inches—as far as you want to bury it—and if it’s loose material, the dirt just boils over. A single Cat—be it a D9L or a 10N or 10R or 10T—there’s just no comparison. The Quad has much more power. We still like them better, although we don’t use them anymore. If you’ve got a very big, long area, they’ll out-perform single machines. But nowadays, you just don’t see that large of a dirt project much.”
Dick Colf in Woodland, WA, owns the last DD9H set Caterpillar ever built, a vintage 1979 model—S/N 97V194 and 98V194. Colf ’s career spans forty-seven years with Kiewit, from project engineer to executive vice president. “From 1979 to 1995, we put twelve thousand hours on that Quad. Its first job was on SR-520, extending the highway from Bellevue to Redmond. I bought it from Kiewit in 2000 and only did minor main- tenance, and then painted it since it was in very good condition. Kiewit owned five Quads in the Northwest and I have the fifth set. The other four were all DD9Gs.”
Kiewit used Quads to push-load scrapers on a number of large earthmoving jobs in the late 1960s and ’70s. “The first job I was on was in 1967 pushing 651s outside Arlington, Oregon along the Columbia River,” says Colf. “Kiewit was relocat- ing a portion of the Union Pacific railroad, and I was an engineer keeping track of how many loads we were getting per hour. We also used Quads to build a section of the highway upriver from John Day Dam. We were borrowing coarse gravel near the river and then building embankments up to one hundred feet high to raise the highway. Kiew- it had quite a few of those jobs. And they used a double D9 on them. We were getting sixty loads an hour, which meant you were only pushing for twenty-five seconds.”
