Hammering away on school complex

The massive rebuilding of the old Ayer High School complex, now the Ayer-Shirley Regional High School, is on target to be completed in the fall of 2015, according to school officials, who say the $56 million project is nearly 25 percent completed. While work is being done on the high school portion of the campus, off Washington Street near the town center, students will continue to have classes in the middle school wing. Seventy percent of total construction costs will be reimbursed by the Massachusetts School Building Authority.
