Featured Projects for the Education Industry


4-plex Elementary Modular Classroom Custom Additions

Clearcreek Elementary School needed a modular school building for much-needed classroom space that blended seamlessly into the existing school structure. For the exterior treatment, our team matched the colors of the masonry, scuppers, downspouts and metal trim of the modular classroom to the existing school structure. The interior comprises four modules, configured into four large 30-by-30-foot classrooms and a hallway. The project was a success, and our customer and the community residents were unable to tell the difference between the original school buildings and the prefab classrooms and offices.

SCMO Education Ross Montessori

Ross Montessori Modular School Building Delivered in Less Than 30 Days

The Ross Montessori School needed a modular school addition before the semester began, leaving minimal time for construction. The building’s eight portable classrooms are arranged in an “H” shape so that each classroom attaches to the school’s central 1,500-square-foot common area. Each classroom is 1,080 square feet with two 4-by-4-foot windows, an exterior door and floors covered in 2/3 carpet and 1/3 tile. While we designed the building as a permanent structure, it can be broken up into five 3-plex units for transportation, should the need arise. We delivered this 11,376-square-foot, 15-plex modular school building in just 19 days, allowing the school to open on time.

SCMO Modular School 8-Plex

8-plex Regis University Modular Office and Laboratories

Regis University required a modular office complex with laboratories, and we were happy to help. This 6,888-square-foot modular school building comprises two 1,080-square-foot classrooms, restrooms, professors’ offices and a resource center. We designed the exterior of the building to match the university’s colors. Five rooftop HVAC systems provide variable heating/cooling zones for the different uses in the building. In addition, energy recovery ventilators in each modular lab add airflow when the rooms are full. All interior walls were designed with R11 poly-encapsulated acoustical insulation, and all corridors have a one-hour fire rating throughout the modular should a fire break out.


Custom Modular Classrooms, Labs and Offices — DePaul Cristo Rey High School

DePaul Cristo Rey High School needed a custom modular building to use for classrooms, science labs and administration offices. The biggest challenge with this project was the plot of land with which we had to work. The modular facilities are perched on a wooded hillside that overlooks the existing campus. Once the site work was completed, the 27 modules were craned into place. On the middle building, a site-built grand entryway was constructed. The team modified the configuration/layouts for buildings No. 1 and No. 2 drastically to allow for offices, labs and classrooms to meet the customer's campus needs. The building façade is a combination of split face block and Hardie panel, along with custom sills. This was a cost-effective project for our customer from the start. We were able to purchase used modular facilities from a past customer for minimal costs. The building costs alone saved the customer in excess of $500,000. This cost saving allowed the customer to install some of the accent items, such as building interior and exterior upgrades, that otherwise may not have fit in their budget.

SCMO Education AOF

Custom Modular Education Building — American Opportunity Foundation

The American Opportunity Foundation project is a 7,968-square-foot modular building comprising 11 12-by-40-foot modules and three 2-by-60-foot modules configured in an L-shape. Designed as a childcare facility, the building has three offices, child and adult restrooms, a laundry facility, a break room, a lounge, day care rooms and a lobby area. The exterior of the building is very modern in aesthetic and has an eggshell white stucco and dark gray façade. We used 12-by-40-foot shipping containers and 12-by-60-foot shipping containers approved by the California Department of Housing & Community Development with a pier and pad tie down foundation, recessed to ground level. All fixtures, doors and windows comply with childcare guidelines, including the 13 child-sized toilets and sinks. The unit is relocatable and built to California Code of Regulations Title 21, a state regulation to ensure modular buildings are of the highest standard using the most energy-efficient materials. The heating and air conditioning units are all electric with heat pumps. Cost-effective choices included the recessed pier and pad foundation that eliminated any cement work for the customer and using standard shipping containers to create a custom unit. The HVACs are end mounted versus roof mounted, eliminating the need for a crane and preventing anyone from climbing on the roof, which can cause safety issues and leaks.


Tennis Team Facility With HVAC, Lights and Windows

This 8-by-40-foot ISO standard container was installed adjacent to multiple tennis courts at an Indianapolis private high school. It is being used as a tennis training facility. The shipping container event space is climate controlled and utilizes the original container doors to lead into an equipment storage area. An exterior door gives access to a space for players to review instructional training videos. The interior is bright due to the 48-inch energy-efficient LED lights as well as high-efficiency windows for observation and natural lighting. The walls are covered with vinyl-covered Luan, and the flooring is finished with vinyl tile. The container was painted to match the branding of the school. The shipping container stands also include an exterior stairwell leading up to an observation deck with a wrap-around fence enclosure that can accommodate up to 42 spectators for a full view of tennis matches.

SCMO Education L.I.F.E.

Energy-Efficient Modular School Buildings — Design to Installation in 170 Days

This 70-by-68-foot modular building was built and installed for L.I.F.E., a place for developmentally disabled children that offers a variety of therapies to help improve their quality of life. With four classrooms, restrooms and three administrative offices, L.I.F.E. was able to increase classroom space while also adding three offices for additional staff members. The town of Gilbert required specific design criteria, such as an extended roof parapet, which helped to hide the mounted HVAC units. L.I.F.E. also required the building to be set below grade, and exterior elements were matched to an existing modular structure on the campus. A fire alarm and security system were connected to their existing system. By using a clear span roof, we were able to secure the structural integrity of the building and allow for future modifications to the building. Given the extreme Arizona heat, the roof was covered using white EPDM, which helps to reflect light, creating a more energy-efficient building. In addition, we installed five 4-ton Daikin rooftop commercial heat pumps. This high-efficiency system helps to save energy while keeping costs low. This project took a total of 170 days from the time of designing and permitting to final installation.


Custom-Modified Modular Classrooms and Break Rooms

This project included 11,788 square feet of classroom and break room space encompassing seven different buildings. The soft beige body and medium brown trim exterior colors were chosen because they blended in with the natural desert surroundings and to assist in shielding the hot summer Arizona sun. The colors were matched to the colors on the existing main campus building. The red colored ramps and steps were chosen to create a playful atmosphere for the students. The interior wall colors were coordinated to blend the VCG with the carpet, creating a pleasant surrounding for the students. The teachers’ break room was designed with functionality in mind. We included a staff restroom, eating area and phone lines all within the same locale.


Modular High School Press Box — Delivered and Installed in One Day

This 340-square-foot stackable modular building was constructed for the Danville High School football field. The structure comprises two separate units, one 10-by-30 foot and one 8-by-10 foot. This unit was shipped and crane-lifted into place on the same day. It sits high atop a structural steel mezzanine built just behind the existing bleachers. Features include an interior stair to a hatch door that opens onto the top deck. The interior provides workspace and electrical hookups for the press along the entire length of the unit, and another 18 feet of locking storage doubles as a platform for second row seating inside. The top unit is equipped with a Raynor rolling door for camera use and two exterior steel doors.


30-plex University of Cincinnati — Wilson Auditorium Modular Building

The University of Cincinnati uses this modular school building as a swing space for the university, which was running increasingly low on space. In addition to adding more modules in a brief period, technical innovations for this project included interior layout changes to the two portable school buildings.

Classroom sizes at the university needed to be considerably bigger than the original classroom areas of the modular building. Our team worked with Mark Line Industries to design larger portable classroom sizes. By removing the load-bearing walls and installing LVL beams supported on steel posts within the roof cavity, we were ultimately able to create clear span modules. This design change allowed us to double the size of each classroom.

The Wilson Auditorium Swing Space project highlights the series of reuse projects we have completed with the University of Cincinnati. The university purchased the used prefabricated school buildings from a local public school district for a fraction of the original cost.

By reusing an existing set of buildings, the customer was able to have their entire swing space plan completed before the start of the fall trimester. With the space in place in such a short time, the university was able to move on to the next phase of its expansion and renovation project.
