Why do we have modular classrooms?

There are several reasons why school systems have to resort to the use of temporary modular classrooms:

A major reason for modular or relocatable classrooms in North Carolina is to accommodate high growth. In an area of continuing growth, it is wise for school boards to instruct their architect to plan for and designate the location of future modulars at a new facility, including stub-outs for power, intercom and other utilities. This allows the board to cope with growth until the next building program takes place. It insures that the location meets the building code for fire separation, distance to toilets and other functional considerations. It could also guarantee that modulars are not placed where a future, permanent addition would be constructed.

In communities with a stable population, but with many buildings built twenty or more years ago, modular classrooms may be necessary to handle new programs and teaching methods. Kindergarten programs began in the early seventies and every school system in the state faced a space crunch. Resource, exceptional children and other specialized programs have been added or grown and have created a need for new space. Reduction in teacher/student ratios increases the need for classrooms. New schools and permanent additions to existing facilities are the long-range solution to this condition.

Teachers no longer line up children up rows in small classrooms. New teaching methods and the introduction of technology within the classroom have made it impossible to use classrooms smaller than 80% of the recommended size in the Facility Guidelines. A double wide modular classroom is often preferable to a small room that would be better utilized for other program needs.

Modular classrooms similar to the single wide units used many years ago typically last about fifteen years before they require a very high level of maintenance to remain serviceable. Newer double wide units with shingled sloped roofs and stained plywood siding should last about twenty years and require less maintenance than the older type. Heating and air conditioning units that are commonly hung on the end of these units tend to have a short service life and may need replacing at least once during the life of the modular.

Yes, this is called modular construction as opposed to modular units. Factory constructed modular components of steel and concrete are transported to the site that has been prepared with foundations and underground utilities. When joined together they are known as modular construction and are a permanent building using pre-manufactured units. Assembly and finish work is required at the site. Larger sections of the building, such as cafeterias and gymnasiums are usually "stick-built" on site. When modular units are assembled to form more than a single classroom and requiring halls, toilets, etc, it becomes permanent modular construction and it must comply with all general statutes related to construction and undergo complete state and local plan reviews.

It could cost more than on-site construction of equal quality. For classroom additions at a school with limited site availability, the shorter on-site construction time could be a deciding factor. The ability to complete the construction during the summer would not delay the safe start of the school year.
