Builder (BU)

SEABEE
Navy Construction - Builders Rating. Mil

Sea-Bees are the construction workers in the Navy.  The men and women of the BU rate are part of the Naval Construction Force.  The term Sea-Bees has grown from when the Navy Builders were part of the Construction Battalions (CB).  The term Sea-Bee comes from the acronym CB for the type of command the Builders deploy with overseas.  

Builders make up the largest segment of the Naval Construction Force.

They work as carpenters, plasterers, roofers, concrete finishers, masons, painters, bricklayers, and cabinet makers.  However, not only are they all the above, they are also specially trained to fight as well as perform underwater construction and qualified in Navy SCUBA diving.

The duties performed by BUs include:

  • building and repairing wood, masonry concrete, and steel structures;
  • installing interior finish work, including installing sheet rock, paneling or ceramic tile walls and installing ceiling and floor tile, millwork and trim;
  • operating carpentry, cabinet-making, and tool and equipment repair shops;
  • building forms for concrete construction;
  • mixing, placing and finishing concrete;
  • operating concrete batch plants, portable concrete mixers and other concrete finishing equipment and tools;
  • building wharves, bridges and other heavy timber structures;
  • reading and interpreting blueprints and preparing sketches for projects;
  • making estimates of material, labor, and equipment requirements.
  • Underwater Construction Teams also perform pier, bridges, and other construction that requires SCUBA diving.

Working Environment

BU's may work in a variety of conditions, independently or as members of a large team. Their many different duties may be performed in climates ranging from tropical to arctic.
