As concrete events go, this was among the biggest. On December 2, 400 people working as well-organized team completed one of the largest single-day pours in the history of Colorado construction. The 120,000-sq-ft. slab at Denver Water Department's Fourteen Reservoir #3, located a few miles south of Chatfield Reservoir, required 3,240 cu. yds. of concrete poured and finished in a 14-hour period. The pour according to Steve Thanner, construction manager for the water and wastewater division of Centric-Jones Constructors, the general contractor on the project, |
the massive pour was completed "without a hitch." Thanner credits everyone involved, especially the planning of Mike Leister at the Denver Water Dept. and the engineers, Bob Bates of Bates Engineering and Diana Horner of Plains Engineering. The pour required 65 trucks and 128 people from Aggregate Industries, the concrete provider, whose drivers logged more than 10,500 miles on the project. Brundage Bone handled the pumping, and more than 100 people from Laursso Concrete did the finish work. The slab is the base of a 25-million-gal. tank that will eventually |
replace treated water storage the water department lost due to upgrades
at two other plants. The tank should be complete in late 2001. |

Huge concrete pour raises logistical challenges, attracts crowd. How many concrete trucks does it take to continuously deliver and pour 3,300 yd. (3,000 m3) of concrete into a hole in the ground about the size of a football stadium? The question was not a trivial matter when Denver Water began laying plans to build a 25-mil-gal (95 × 103m3) underground water reservoir for its Foothills Water Treatment Plant west of Denver. The storage tank—the biggest circular post-tensioned concrete water storage tank west of the Mississippi River—posed challenges that required 31/2 months of preparations. |
