Pre-cut in translation from English means “pre-cut”. The secret of the technology is in the preliminary preparation of the elements that make up the supporting structure of the building, and lumber.
Each part of the house kit is cut out at the factory in advance, in accordance with the project plan, and the parts are connected on the spot. In addition to the kit are sheet materials. Ecowool is most often used as a precast heater.
During the construction of a wooden-frame house using the pre-roll technology, the building is assembled from pre-fabricated elements of the required length, which have ready-made connections to each other, said Makim Morozov, founder of M9 development. However, for the assembly of such houses, a team of professionals specializing specifically in rolling is needed, and in our country there are not so many of them yet.
Advantages and disadvantages
To create a pre-cut, you do not need sophisticated equipment, a developed project and a standard set of tools for processing lumber are enough. “Since the construction of the house does not have a huge weight, you can save a lot on the foundation of such a house. Therefore, the main advantage of this technology, of course, is the price,” Apanasenko specified. According to him, the average cost per square meter of such a house is 35-40 thousand per square meter. m.
The average pre-roll assembly time is from one and a half months or more, the head of Waldek noted. According to him, in this case, the client receives materials for construction, which must then be assembled. It takes much longer to assemble such a house than using other technologies (prefabs or modules), which can be attributed to the disadvantages of the technology.
When choosing to build a house from a pre-sale kit, it is important to understand that it is necessary to carefully control all stages of construction in the process. The preparation of lumber does not require special sophisticated equipment, but there is a big risk that such production will turn out to be artisanal, and all the wooden elements prepared on it will not be of the quality that was expected, Apanasenko specified.
“After the delivery of sawn timber to the site, it is necessary to think over the conditions for their storage. It is highly undesirable that they be exposed to atmospheric precipitation, ”the expert specified.
Brigade of workers
The disadvantage is that, unlike modules for assembling such a house kit, it is extremely important to choose a professional team with good experience in building such houses, and it is best to document all work (contracts, acts), the head of Waldeck said. He recommended that you do not try to build such a house alone if you do not have experience.
So that the price does not increase during the assembly process, you need to have a professional team of builders with technical supervision at the facility, which controls the quality of both the supplied materials and the assembly of the house kit. Otherwise, the low initial price threatens to rise significantly, and the construction will be delayed, the expert concluded.
