Estimated to build a house from a bar: how to make it

Despite the powerful development of nanotechnology and advanced construction methods, wood, as the main and facing building material, is still in value. But after the development of the project plan, we will definitely need an estimate for the construction of a house from a bar in order to be able to preempt any unforeseen situations that arise when paying for any work or materials.

For such a calculation, you can use the services of a construction company, but you can do it yourself, which we will learn below, and you will also be given the video in this article.

How much money is needed to build a wooden house

To make an estimate for the construction of a house of timber, we will have to take into account not only its walls, but also the foundation and roof. Since we will be doing calculations for example, our attention will be paid exclusively to the box, without any finishing, that is, to the foundation, walls and roof.

We will try to understand the principle itself so that you can use it when using any timber - profiled and smooth, solid and glued.

We make a project

• Итак, наша смета на дом из бруса будет составляться по проектному плану, приведенному выше, где есть гостиная, спальня, кухня, санузел, тамбур и терраса, для которой нужен фундамент и крыша, но не нужны стены. В качестве основания мы возьмём монолитный малозаглубленный ленточный фундамент, стены сделаем из цельного непрофилированного бруса 200×200 мм, а перегородки из такого же материала, но 100×100 мм. Вы можете применить другой тип фундамента для брусового дома и другое сечение и конфигурацию профиля, но суть подсчётов при этом не изменится.
• As a result, we get the bearing walls: 9m - 1 piece; 7m - 1; 5.5m - 2; 3.5m - 1; 1.5 m - 1. Partitions: 5.5 m - 1 piece; 4m - 1; 3.5m - 2; 3m - 1; 2m - 1. Two more sides of the terrace will be added for arranging the strip foundation: 3.5m -1 piece; 1.5 - 1 - here it is better to fill a full-fledged tape in order to put supports under the roof without any problems, and if necessary - to build walls.

Foundation

• МФ не будем углубляться в технологическую сторону вопроса, так как нас больше интересует смета строительства дома из бруса, поэтому сразу перейдём к подсчётам. Предположим, что ширина ленты у нас будет 0,4м, глубина от поверхности грунта – 0,5м, а верхняя часть (цоколь) – 0,4м, значит, в итоге мы получим сечение 0,4×0,9м, а общую длину мы сейчас узнаем. Не забываем также о том, что для монолита нужен арматурный каркас, который тоже будет участвовать в расчётах.

• Now we need to calculate the total length of the entire trench and for this we need to use the project plan and put together all the walls and partitions: 9 + 7 + 5.5 * 2 + 3.5 + 1.5 + 5.5 + 4 + 3.5 * 2 + 3 + 2 + 3.5 + 1.5 = 58.5m with a terrace. Now we need the volume of the tape to find out the necessary amount of concrete to fill it: 58.5 * 0.9 * 0.4 = 21.06 m³. You can buy ready-made concrete by ordering it at the concrete goods plant or prepare it in the concrete mixer yourself using the table shown in the photo above, and the cost will depend on the price of the ingredients.
• You can include a pillow in the estimate, which is poured under the base of the tape and has a minimum thickness of 0.2m and for this purpose either gravel (crushed stone, screenings) or coarse sand is used. The calculation is performed in the same way: 58.5 * 0.4 * 0.2 = 4.68 m³ sand or rubble.

• For arranging the framework with our own hands, we will need 4 (four) longitudinal supporting rods of corrugated reinforcement with a cross section of 12 mm and for the connecting ring vertically - 2 pieces of smooth reinforcement 0.7 m and horizontal - 2 pieces 0.25 m (section of the rod for the ring - 8 or 10 mm). The distance between the rings is 0.5m, the joints are made with soft steel wire.
• So, we consider longitudinal reinforcement: 58.5 * 4 = 234m, but we have two tapes of more than 6m (rod length), which means we need to add a meter to each joint for a tire, which means 234 + 8 = 242 m of total length. And if this is translated into rods, we get 242/6 = 40.3 or 41 pieces.
• Now let's calculate the rings: 58.5 / 0.5 = 117 plus one per edge, total, 118 pieces. Each ring has 0.7 * 2 + 0.25 * 2 = 1.9 m. Then 118 * 1.9 = 224.2 m, and in rods it will be 224.2 / 6 = 37.4 or 38 pieces. Knitting wire can be purchased only in coils, so it does not make sense to count its metric area, but just in case you can adopt, that about 0.5 m is spent on one joint.

Walls

• Для начала устанавливают оклад и если делать его из такого же материала, то нам понадобится для него 9+7+5,5*2+3,5+1,5+5,5+4+3,5*2+3+2=53,5 м бруса сечением 200×200 мм (террасу не учитываем). На него устанавливаете лаги, чаще всего они в таких случаях бывают сечением 150×50 мм или 200×50 мм – их мы считать не будем, так как это уже пол. Теперь нам нужна смета дома из бруса по несущим стенам и давайте возьмём для подсчётов их высоту в 2,8м (можете подставить другие цифры).
• Несущих стен у нас 9+7+5,5*2+3,5+1,5=32 м, а для заданной высоты нам понадобится 2,8/0,2=14 рядов. В таком случае, 32*14=448м бруса сечением 200×200 мм. Если цена древесины такого рода у вас определяется в кубометрах, то для этого можно легко узнать его объём: 448*0,2*0,2=17,92м³.

• Теперь давайте сосчитаем количество дерева для перегородок, учитывая, что у них одинаковая высота с несущими стенами, но вычеты для дверных и оконных проёмов при этом делать не будем – нет смысла. Всего перегородок получится 5,5+4+3,5*2+3+2=21,5м, но здесь сечение уже 100×100 мм, тогда понадобится 28 рядов: 21,5*28=602м бруса сечением 100×100 мм, но если перевести это в кубы, то мы получим 602*0,1*0,1=6,02м³. This means that only 17.92 + 6.02 = 23.94 m will go to the walls.³.

Council As we have said above, it is not necessary to deduct the beam for openings for windows and doors when calculating. You still need wood for making dowels, and the waste here will be very appropriate.

Roof

• It is not difficult to calculate the amount of material for the roof, having a project plan in hand, but you need to know exactly what kind of roof you are going to make. We will not list all types of roofs, but consider a simple gable option that is suitable for this project of a log house or cottage, although here it is quite possible to equip the attic. The distance between the rafters here is determined by the height of the ridge and the higher it is, the smaller the step, which can be from 0.4 to 1.0 m, as required by the instruction.
• If there is no attic, then in this case it is possible to make a height of 1.5 m, therefore, the rafter legs will be exactly like that, and the step here will be 0.7 or 0.8 m. For rafters and racks in such cases use a 150X50 mm profile, and here for struts, you can use the bar to 100 mm. You can use an unedged board with a thickness of 20-25 mm for sheathing a skeleton from a timber - this will be somewhat cheaper than edged.

Council Under the roofing material (usually a sheeting or metal tile, less often - slate), put a roofing material. Estimated at the same time will not increase much, but the benefits will be undoubted - it will reduce noise during the rain (blows drops on the roof) and will serve as a heat insulator.

Conclusion

What you have just read is only an example of how calculations are made, but in fact, the estimate for building a house from a bar includes not only basic materials. We even dropped some of the little things out of the box, for example, impregnation and tow, and in fact for the residential building you need many more different elements and materials, and also includes the arrangement of communications. All this is possible to calculate, having a ready-made project.
