The town's only elementary school, a preK - 6 facility serving 604
students, has seen significant enrollment increases in recent years. The
70,638-square-foot school is a one-story structure built in 1950 with
three subsequent one-story additions. The town needed to expand the
existing school quickly to keep class sizes within limits or temporary
classrooms would have been required. Flansburgh Architects was retained
to conduct an extensive feasibility study to determine whether to
replace or renovate the school.
Flansburgh Architects recommended retaining and renovating all portions
of the school and adding 34,385 square feet of classroom, music, and
support space. Twenty-two classrooms were added. Renovations include
all-new HVAC systems utilizing the state-of-the-art displacement
ventilation system, which provides a more healthful and quieter
environment for a better learning; an expanded cafeteria; and
reconfigured kindergarten rooms and library. Site improvements include a
new baseball field, play areas, and expanded parking. The completed
school addition complies with MA-CHPS (Massachusetts Collaborative for
High Performance Schools), a certification which encompasses school
design, construction and operation, energy and water use, lighting,
temperature control, and acoustics. Precast concrete panels met several
of the criteria for environmentally friendly schools.
In order to meet the pressing need for an aggressive design and
construction schedule, Flansburgh employed two strategies: building the
needed classroom addition using a pre-cast concrete wall, floor, and
roof system to minimize erection time so that it will be completed in
only nine months; and utilizing the CM-at-Risk process to fast track the
design and construction sequences.
To meet the tight schedule, the site and foundation work were performed
while the precast design was being finalized to save valuable time. By
the time the foundation work was completed, the precast insulated wall
panels and hollowcore floor/ceiling planks were ready for erection, and
the entire two stories were fully enclosed in just three weeks.
The project was constructed in six phases so that the school remains
fully functioning. By completing the addition quickly, students will be
moved in phases into the addition from portions of the building to
accommodate the needed renovations while keeping the school fully
The key design challenge was to meet the aggressive design and
construction schedule. Not only did the use of precast concrete panels
allow the project to on time, it allowed the project to finish 9 months
ahead of schedule.
One of the advantages of using precast concrete panels was the variety
of exterior choices available. To match the existing school, thin brick
exterior was used, which eliminates the need for periodic sealing or
tuck-pointing required with traditional brick.
Precast Building Systems meet the criteria for high-performance school
building. They provide acoustical superior sound isolation, low-lifetime
maintenance, lower heating and cooling costs, and improved air quality.
