The Wilkes County Commissioners were given an update yesterday on the progress on the construction of a new jail or Wilkes County Detention Center.  The project began in April of last year, and Jack Hemphill of Hemphill-Randell Assoc stated that they are now beyond half way through and on target with the construction and funding in spite of record breaking rain last summer and record breaking cold last month.  Commissioners asked about any cost over-runs but were told that while contingency cost nationally usually average about 5 percent of the total cost, so far, any contingency costs with this project were only 3/10 of 1 percent.  Project Manager Kris Little said the building is now under roof and work is progressing well. They still expect to have construction completed by the end of July or first of August which will be followed by inspections and Sheriff Dept training on using the new facility.  Chairman Gary D. Blevins suggested that they have future discuss and development of parking and security for the judges entering and leaving the courthouse.  Commissioners Keith Elmore and Eddie Settle said they were very impressed with the work accomplished on the new detention center and believed the project was going well.  Project Manager Kris Little reminded Commissioners that this is an economic boost to Wilkes as several people working on the project live here in the county.
