PIERRE | Six contractors submitted bids to rebuild the S.D. Highway 34 bridge over Chappelle Creek 22 miles east of Pierre in Hughes County.
The least expensive was 23 percent more than the project engineer expected. Nonetheless, the state Transportation Commission awarded the project Tuesday to the lowest bidder, Swingen Construction Co. of Grand Forks, N.D.
The company proposed doing the work for $710,436, while the estimated cost was $576,311.
Sam Weisgra, who oversees the bid process for the South Dakota Department of Transportation, recommended accepting it. “This work needs to be completed through the fall and wintertime frame,” Weisgram said. “We don’t want to go through another freeze-thaw cycle.”
He indicated the higher bid prices probably reflected expectations of colder weather.
Commission chairman Ron Rosenboom of Sturgis said the six bids seemed to be “highly competitive” and indicated the process was “pretty honest.” The roll call was 6-0 in favor.
The commissioners awarded six other contracts, including one in West River.
Tru-Form Construction Inc. of Black Hawk was low bidder of three companies wanting to make turn-lane modifications at Interstate 90 Exit 67 in Pennington County.
Tru-Form proposed $154,274, and the project engineer’s estimate was $159,681.
