Pointing to the nightmare of the behind-schedule Dibrell School expansion, architects believe Morrison School will avoid similar delays and expect it to be available for students by the beginning of the next school year.“As far as the schedule, they are moving along out there,” said school architect Paul McCall of Red Chair Architects (formerly Cockrill Design) about the progress at the new Morrison School. McCall made his report to members of the Warren County School Board on Thursday night, noting there is presently a June 23 estimated completion date. His power-point presentation of Morrison School’s progress came as board members expressed concerns about how sluggish construction at Dibrell School has left the campus still uncompleted months after its expected date.“We don’t want to see what has happened out at Dibrell happen out there,” said School Board chairman Scott Holmes, saying should weather delays push back the schedule the contractor could be pressed to have the school open for the 2012-13 year.School system maintenance supervisor Donnie Caldwell said the contractor at the Morrison site has been more aggressive with subcontractors in making sure they meet deadlines.
