Great Falls Construction has begun renovations and expansion of the Mabel I. Wilson school in Cumberland along with the construction of a new building for the district’s youngest students.
The $35 million project includes a 76,700-square-foot school for pre-k, kindergarten and first graders and renovations to the existing elementary school, which will include the addition of 6,300 square feet for four classrooms.

The projects were approved by district voters in June 2024 as part of a $53.5 million bond that included construction of a $3 million turf field for the high school and a new maintenance building for the campus.
The Mabel I. Wilson school enrollment exceeded its 550-student capacity in 2015 and has been using modular classrooms. The school serves students in grades pre-k through fourth grade from North Yarmouth and Cumberland.
The new building is being built on a 2.3-acre lot adjacent to the SAD51 campus off Tuttle Road in Cumberland. It’s expected to have a capacity of 550 students when completed in June 2027.
North Yarmouth-based A.H. Grover Inc. is managing site work on the project and Stephen Blatt Architects, based in Portland, is the design team.
