PIPELINE CONTRACT AWARDED
A $19,156,946 contract was awarded on June 27 to Carstensen Contracting of Dell Rapids, SD for the middle 12.6 mile segment of 24 inch pipeline between Beresford and Sioux Center. Designated as IA – Segment 3 (IA-3), this is the third and final segment of pipeline needed to connect the two communities. “For reasons that were not unexpected, the low bid for IA – 3 unfortunately was significantly over budget. However, the other two segments of pipeline between Beresford and Sioux Center came in significantly under budget. Combined these three contracts came in $1.1M under budget,” said Executive Director Troy Larson.
Carstensen also was the low bidder for the segments of 24 inch pipeline to the west (11.2 miles) and east (10 miles) of IA-3. Collectively these three segments of pipeline are referred to as the “Iowa Transmission Line”. The IA-3 contract includes two separate parts – pipe installation and pigging and disinfecting the entire 33.8 miles of 24 inch pipeline between Beresford and Sioux Center. Construction on IA-3, which includes the Big Sioux River crossing, is anticipated to begin in the summer of 2020. July 2021 is the substantial completion deadline for pipe installation, but the substantial completion deadline for the pigging and disinfection is not until July 2022. “Our current goal is to deliver water to Sioux Center and Hull by late 2022. We want to disinfect the pipeline as close as reasonably possible to when we put it into service,” said Operations Manager Jim Auen.
