At building of buildings carry out earthen, assembly, stone, concrete and ferro-concrete, plotnichnye, joiner's, roofing, finishing, sanitary-engineering, electrotechnical, and also other kinds of civil work. We will consider only plotnichnye and joiner's works.
To plotnichnym and to joiner's works almost all kinds of works connected with processing or use of a tree concern. In building carpenters perform simple work with a tree. Joiners carry out more a delicate work, processing or mounting products from ostrogannoj and even the polished wood. In the work they apply the various tool. Nevertheless sharp border between the carpenter and the joiner it is impossible to spend. The good carpenter not only owns the joiner's tool, but also performs many joiner's works as well as the joiner can perform work of the carpenter, for example, to lay a deal floor, to make a timbering, etc.
Carpenters produce elements wooden rublennyh houses, collect wooden houses, do rafters at the device of roofs, produce a timbering, collect and rearrange woods and podmosti, establish window and door blocks, do floors and partitions, make working stock.

Joiner's business was born from plotnitskogo with the advent of tools and the receptions, giving the chance to receive smooth surfaces and exact details. The essence of joiner's business consists in ability purely to process and connect among themselves in a product pieces of the tree received from a round wood trunk. Furnish has appeared much later. In the beginning all joiner's products were carried out in a natural tree - a file.
Today in joiner's business find application as thick bruski and the boards possessing the big durability, and very thin plates, such as the plywood interline interval, demanding a wooden basis. The interline interval is used only for facing. A surface of boards and bruskov process vystragivaniem, porezkoj, tocheniem. As the natural basis of a joiner's material has not changed is a same tree, the principle of its processing so, and receptions of old masters, in perfection owning the manual tool, can quite serve the today's master has remained also, whose work is still facilitated by use of mechanisms.
Joiner's skill along with ability to choose a material and to give brusku the necessary form demands also the account of constructive work of it bruska in a product, proceeding from a direction and the form of its fibres. As it is known, there is a set of different breeds of a tree, they differ colour, a structure and durability of wood. Each breed has the features in processing and furnish. Joiner's art consists also in being able to define breed, the nobility of its feature - merits and demerits, to be able to find in a tree piece - preparation - the parts most suitable to obverse details, to be able to connect among themselves different breeds so that this connection was harmonious, beautiful and would correspond to the constructive characteristic of a product.
Any joiner's product consists of the separate details connected among themselves. It is necessary for master to be able to choose type of a sheaf of details, the form and character of their processing in junctions, and also fastening materials. Ability to define section necessary for a given place with the account not only works, but also beauty - one of the main components of joiner's art. The master should possess feeling of proportions and that is called as feeling of a tree.
