Constructions are buildings such as floors, walls, and stairs. They can be made of boulders, logs, blocks, and bars of any solid material—including wood, stone, metal, glass, clay, and even soap—and are accessible in the uild- onstruction menu. One exception is the track stop, found in the construction submenu even though it is a regular building.
Unlike most objects accessed from the removal, suspension, and an idea of the current status before the construction is complete.uild menu, Constructions are treated as inert terrain features when completed, with a few limitations as described below. Additionally, constructions can only be interacted with by loo -ing at them or by pressing - to designate their removal. Using the uery or ask selection will give no information after the construction is completed, but will allow
 Required labors
In order to make a construction, a dwarf must have the "Wall/Floor Construction" labor enabled, found under the "Other Jobs" heading.
The construction removal labor is required for removing constructions.
No experience is granted when building or removing constructions.
 Constructions and mines
Constructions are similar to mined out formations. However, unlike the walls and floors surrounding mined or channeled spaces, constructed features cannot be smoothed, engraved, or carved into minecart tracks. In order to construct smooth stone walls and floors, blocks need to be used in place of raw stone. Wood, metal, and glass constructions are not considered either rough or smooth, but in the case of wood, building with blocks will increase room value - metal bars have the same value as metal blocks and are thus interchangeable (though blocks may be preferred to simplify resource tracking), and glass can only be used in block form.
 Order of construction
Constructions are built in a Last-In-First-Out (LIFO) order. That means that whichever constructions are ordered first will be built last. Also, if there is a large group of constructions being built, and a new set of constructions is ordered, the constructions in progress will be ignored until the new constructions are finished.
Respecting the LIFO order is also necessary to efficiently and correctly construct multi-z-level walls.
Constructions are generally inert, resisting building destroyers, but will be destroyed if magma and water can interact in the square of the construction to form obsidian, or in a cave-in. Building and removing a construction can change the floor it is built upon to a default value, removing things like engravings and the "magma flow" floor above semi-molten rock.
