Architectural Excellence:
This two classroom, two bathroom 1,344 square foot facility
was designed and engineered to be the prototype modular building
for the entire NYC School District. The building design
and specifications were approved by the NYC SCA and FID after
a rigorous review and submittal process. M Space Holdings
was awarded a two year exclusive vendor agreement to supply
these units throughout the five boroughs of the NYC School
system. M Space has provided fourteen (14) of these
TCU’s to date in both stand alone and back to back
configurations. The building units are designed to
provide additional classroom space for existing schools or
to be clustered together to form stand alone schools. The
open floor plan allows the SCA to convert the units to administrative
space, nurses offices, and any other type of area as needed
by the different schools.
Technical Innovation:
This facility was built to meet construction group 1-E non-combustible
and the rigid NYC building codes, including mechanical and
electrical equipment MEA certification. The buildings
rest on M12 x W26 perimeter steel I-beam frames to increase
rigidity, allowing for multiple relocations, and an increased
lifespan. The floor is comprised of 16 gauge 8” steel
joists under ¾” fire rated plywood and ¼” underlayment. Exterior
walls are comprised of 18 gauge 3-5/8” steel joinse,
1-1/2” 20 gauge steel desk, 5//8” Densdeck barrier,
tapered polyiso insulation, and ¼” Densdeck
prime cover board. Anti-graffiti coating, 26 gauge
1-1/4” ribbed steel siding, HS-HC60 heavy commercial
window guards, 16 gauge 1-3/4” galvanized and insulated
doors also increase the durability of the units. Fully
cantilevered 4’ x 6’ stainless steal canopies
are positioned over each door for weather protection.
Cost Effectiveness and Energy Efficiencies:
Due to NYC shipping restrictions and security concerns, the
modular buildings were delivered at night and set via crane
utilizing spreader bar and straps as they arrived that same
evening (typically double-wide modular buildings are landed
and seamed weather tight by sunrise). The units HVAC
system exceeds ASHRA requirement for sound. The Exterior
walls include 3-1/2” sound attenuation blankets and
all sheathing joints are taped and caulked with 2” 10
x 10 glass mesh joint tape. All steel siding and bottom
board has continuous sealant at laps of panels to reduce
moisture. The roof consists of .060 fully adhered EPDM, 1A/1-90
(Carlisle) rating with 20 ml. top coat. The entire
building is insulated with mineral fiber with the following
R values: floor R-22, walls R-13, and roof R-23.45. The
attention to the material specifications makes this building
a very energy efficient design.
