Work is expected to begin in mid-April on $37.7 million in construction and renovations at Niagara-Wheatfield Central Schools.
Most of the plans have been approved, and the School Board recently awarded more than $26 million in contracts for the work, approved by voters in late 2004.
Some schools will get additions, and most buildings will be renovated and improved to accommodate the district's growing enrollment.
