Columbus School Board selects Burlington firm for infrastructure improvements Jim Rudisill for The Hawk Eye COLUMBUS JUNCTION — A Burlington consulting firm has been given the job of seeking bids for several proposed Columbus School District building infrastructure improvement projects, after submitting a proposal cutting the estimates submitted earlier by another consulting firm by nearly $200,000. The school board agreed during its regular monthly meeting Monday to accept the proposal from Klingner and Associates, after comparing the estimates in that package to estimates provided last month by Shive-Hattery Associates, Cedar Rapids. At last month’s meeting, the board tentatively agreed to direct Shive-Hattery to seek bids for replacing a chiller at the Roundy Elementary building and for cooling and dehumidifying the middle school gym and the auditorium.
