Job Responsibilities
An Army carpenter and mason specialist enlisted in the United States Army is an individual who enters the military to gain skills in carpentry, masonry, or both. They are skilled in all aspects of construction work related to building construction. It is an entry-level skill unrelated to any specific job. The mason works with stone, brick, tile, mortar for construction purposes, while the carpenter deals with woodwork, including constructing furniture and window frames that are not structural components but are still used for decoration. The person should be able to cut wood accurately using a circular saw as well as weld sheet metal on a metal framework by hand or by the power source. They should also be able to install wall and floor tile as well as concrete and glass blocks. A good sense of balance is preferred since they will be standing on ladders or scaffolds for long periods.
Fundamental carpentry and masonry task

Performing basic carpentry and masonry skills is a responsibility of Army Carpentry And Masonry Specialist (MOS 12W), which is an army career classification that represents “civilian construction craftsmen supporting the United States Army.” The skills are necessary for military building projects that are located off the U.S. or Canadian coast. To achieve this, MOS requires a combination of trade skills, including woodworking, carpentry, masonry, electrical work, plumbing, and sheet metal work.
Rigging devices and trusses maintenance

Carpentry and masonry specialists maintain rigging devices, trusses, cable stays, bridge structures, or other structures designed to support the weight. They are also responsible for testing the strength of the structures they maintain. Using hand tools and power equipment such as electric drills, grinders, saws, sanders, air compressors, or hammers to support structures are part of their duties. Routing or operating electric lines is also a task for this job title.
These specialists inspect structural members that have been treated with fireproofing materials to ensure that their integrity has not been compromised by fires. They may use specialized equipment such as lasers to detect cracks in structural members while using other methods such as magnifying glasses and telescopes. They may also perform similar tasks for watertight integrity, such as inspecting rivets or bolts, drilling seals, and inserting plugs to prevent water leaks.
Carpentry and masonry specialists inspect structural members in warehouses and storehouses for signs of cracking and other damage. They may use specialized equipment such as lasers to detect cracks in structural members while using other methods such as magnifying glasses and telescopes.
Maintaining the strength of the structure reduces the chance that additional firefighting efforts will be necessary. This helps ensure that the structure remains standing during an emergency to prevent loss of life, injury to people, or damage to buildings or other property.
Combat engineer missions assistance

The job of a carpentry and masonry specialist is to assist in the performance of combat engineer missions. It requires specialized knowledge, skills, and abilities in order to construct, repair, demolish and maintain buildings, roads, bridges, highways, and other civil engineering projects. Combat engineers are responsible for designing and constructing fortifications such as bunker systems or trenches as well as bridges to support military forces in their missions. They also guide their units during combat operations at the tactical level by providing pre-mission plans for maneuver units. Combat engineers can help save lives by establishing temporary roadways or building temporary bridges that can be used at the scene of buildings damaged by enemy fire.
The Army is currently short of qualified personnel who can fill the position of carpentry and masonry specialists. This means that future carpenters and masons will need to transition into combat engineer fields. This transition is necessary because of the heightened demand for construction work in war zones around the globe due to military operations, natural disasters, and humanitarian concerns.
Concrete forming
The carpenter and mason are responsible for building concrete forms that will support the construction of walls, slabs, or columns. The carpenter-mason generally works in teams with the bricklayer to prepare for construction. They have to work in order to fit openings where pipes are being installed, wiring is being put in the walls, floor slabs are being laid out, or electrical equipment is being set up. Other tasks include assembling scaffolds for constructing walls and slabs. Working on different types of foundations may also be part of the job description. A carpenter-mason must exercise safety by following all safety rules during all activities under their supervision at all times.
Building layout, structuring assistance

A carpenter and mason are typically responsible for assisting in the building layout, framing, sheathing, fabrication, and roofing structures. This job deals with all different types of materials such as steel beams, wood framing systems, siding materials like plywood. Your typical tasks will be cutting boards or beams to size using a circular saw or table saw. You may also be dealing with metals that need to be cut by using a plasma cutter. You’ll also likely have to fabricate much of the material you’ll use in this position because it won’t come prefabricated at the stores you visit. You’ll also perform tasks like placing insulation inside walls, drywall installation, installing cabinets, painting, tiling, etc.
It is necessary to note that the primary duty of a carpenter is to plan and install finish flooring. There are carpenters who do not fabricate the materials for this position but solely perform the installation. This will be your primary duty if you are in this type of position. If you do not care about flooring installation, then this may not be the career for you. There are also engineers who only do carpentry work as part of their programs but many times, and they join an established carpentry company later on in their career.
Besides being an integral part of building structures, carpenters and masons also must have a good knowledge of building codes. Knowing the codes will help you plan ahead for your structures and layout your project correctly.

Building carpenters may work in office buildings, schools, hospitals, and hotels where they specify materials used to install bathrooms, ceilings, floors, and walls.
Brattice builders
Brattice builders construct brattice, which is a latticework barrier used mainly in construction work and military combat situations. Brattice consists of a series of parallel timber or steel panels that give support to an overhead structure without closing off the area below completely. Brattice is used primarily to reduce the risk of falling objects from striking workers, equipment, or material below.
Brattice may be constructed as a temporary or permanent structure and supports other building and construction components such as tanks and boilers, as well as tanks and heavy artillery. Brattice builders cut lengths of wood to dimensions given in engineering drawings and use shears to cut sections down to size. They match sections by using complex engineering drawings that specify measurements, material requirements, and the type of brattice required. Brattice builders attach panels together using nails, screws, or bolts, depending on the construction design.
They also screw bracing cross pieces to panels, making sure that it is strong enough to withstand the weight of objects placed on them. They may cut and fit additional wooden or steel braces to add stability and support or to add to the brattice’s height. They use calculating instruments such as rulers, squares, and calculators to measure and keep track of materials while they build brattice.
Carpenter apprentices
Carpenter apprentices must be able to use power tools, which can include handsaws, circular saws, drills, sled hammers, planers, air compressors, and nail guns. Carpenters must have a basic knowledge of carpentry terms such as framing lumber for the installation of doors or windows. They must also be able to adjust their tools or change their formats to accommodate different materials or sizes of materials.
Carpenters must know the basic steps of a job, such as first measuring a room to determine if a piece of furniture will fit into it. They also must know how to account for differences in room sizes, such as compensating for uneven floors. Carpenters must be able to use their hands and fingers to feel the dimensions and positions of objects and materials.
Carpenters must follow specific safety rules for using power tools or other equipment. They also may need special training on the installation of special products, such as reinforced concrete beams used in new construction or satellite dishes used on top floors of tall buildings.
