COSMIX repairs on the way

If you've been on I-25 in Colorado Springs lately you may have noticed a bit of a bumpy ride. Dips in the road are making for one headache of a commute. "About two weeks ago we went in there and we did have some panels that had settled and created a lip there. It was causing some problems. We got some complaints." says CDOT and COSMIX Project Manager Don Garcia.

When the complaints came in, CDOT crews drilled holes in the road to check the soil. What they found was loose and wet soil underneath the road which was causing it to form dips in the road. The fix? Drilling holes and filling them in a process called compaction grounding. "They drill holes into the ground and they drill some grout, aggregate and a little bit of cement in there and what that does is strengthen and densify the soil." explains Garcia.

Normally the bill would fall on the taxpayers for this type of work but because this COSMIX project was done through a process called "design build", the state has a warranty on the work. It's a relief for tax payer in an already tough economy. "The warranty is on the contractor." explains Garcia, "If it was a traditional project, once the project was done and accepted CDOT would have to foot that bill. In this instance the bill is all on the contractor."

Garcia tells News First the road work on I-25 should start sometime within the next two weeks. The work will be done in night and weekend intervals. The hope is to have all work completed by mid-December.
