News : New 911 Call Center Faces Construction Freeze
Columbia, MO, USA, March 23, 2015 - Winter's passing is good news for those interested in a speedy completion of Boone County's new 911 call center. Snow, ice and rain have caused significant delays since ground broke in late February.
Seventeen potential construction days have so far been forsaken due to weather, and soft ground will cause a further delay of at least four days, pushing the estimated completion date into May 2016. The delay will increase the cost by up to $75,268, which the Boone County Commission approved Thursday through a change order.
The soft soil will be replaced with gravel that can support a road needed to bring in construction equipment and supplies to build the emergency communications center. In this case, county inspector Dan Marshall said, this primary avenue for construction equipment will become a secondary access road when the center comes online.

Erik Miller, vice president of consulting firm PWArchitects, said the problem became apparent when machines first started to move into the construction site. Despite its tracks, a backhoe started sinking into the earth, and it took a bulldozer and chains to pull it to solid ground.
The main construction site was surveyed, but the area around the access road was not, and the development team was surprised to find ground too soft and too treacherous to trust with a proper asphalt road.
"You just can't foresee every problem," Marshall said.
Miller said the soft soil will be replaced by a five-layer fill: a layer of geotextile fabric, a couple feet of rock, a layer of geogrid fabric, more rock and then a final layer of geogrid, which is used to keep gravel from shifting.
At Boone County Southern District Commissioner Karen Miller's request, the dirt that will be taken out of the area will be kept around the construction site to fill in elsewhere.
