The BU Rating
In 1948, the Navy Builder rating became an off-shoot of the original Carpenter's Mate rating. The Carpenter's Mate rating was one of the original United States Navy ratings as it was first established in 1794.
The Navy's computerized personnel system associates the rating name with an alphanumeric Navy Occupational Specialty (NOS) code. For BU, the NOS is H100.
Navy Builders make up the largest segment of the Naval Construction Force, the SeaBees. They work as carpenters, plasters, roofers, concrete finishers, masons, painters, bricklayers, and cabinet makers. Opportunities to enter the BU rating are good for qualified applicants.
This is a 5 year enlistment program. The Builder class "A" school is approximately 14 weeks long, and it is located in Gulfport, Mississippi.

The duties performed by Navy Builders include building and repairing wood, masonry concrete, steel structures, and installing interior finish work, including installing sheet rock, paneling or ceramic tile walls and installing ceiling and floor tile, millwork and trim.
BUs operate carpentry, cabinet-making, and tool and equipment repair shops, and build forms for concrete construction; mix, place and finish concrete, and operate concrete batch plants, portable concrete mixers and other concrete finishing equipment and tools. BUs build wharves, bridges and other heavy timber structures.
They read and interpret blueprints and prepare sketches for projects, and make estimates of material, labor, and equipment requirements.
