The Dawson County Board of Commissioners last night voted to approve purchases of a new Computer Aided Dispatch system for E-911 and to ratify an agreement that will transfer the operation of Fire Station 8 to Pickens County, among other items. County to update current E-911 computer system Purchasing Director Melissa Hawk presented a proposal to upgrade the county’s current Computer Aided Dispatch, or CAD system, in order to fix issues that sheriff’s office staff have been dealing with for several years in regards to 911 calls and dispatch. Hawk presented a quote for a sole source exemption, meaning the county would not have to follow the requirements for a bid process in order to purchase an upgrade to the county’s currently owned system. The board voted unanimously Jan. 17 to purchase the upgrade at a cost of $421,260.15.
