How to calculate the scaffold area?

Scaffolding is a temporary structure made of metal rods and wooden platforms used to house materials and the builders themselves to carry out installation work. Such structures are installed both outside and inside the building for finishing various surfaces.

To order scaffolding, it is necessary to correctly calculate their area. It is worth considering in more detail how this is done and what must be taken into account.

There are several options for calculating scaffolding. The first involves calculating by area. In this case, you should pay attention to the following parameters.

1. Wall height. For the calculation, you will need to add one to the actual indicator to get 1 m2 with a margin. Then it will also be possible to take into account the safety requirements, because it is necessary to install fences on the scaffolding, requiring additional space.
2. The length of the façade or interior wall. Using this parameter, it will be possible to find out the number of sections that will help close the entire wall for high-quality and safe outdoor or indoor work.
3. Construction type. It will affect the size of the sections that the scaffolding will consist of. So, for example, in the calculation, it may be necessary to take into account the consumption of pipes.

The wall length in the example is 21 meters, and the structure type is frame. Then the height of the section will be equal to 2 meters, and it will be necessary to purchase 11 sections to cover the entire wall. Thus, in order to calculate the square meters of scaffolding, it will be necessary to multiply the height (8 meters) by the length (22 meters), and the result is 176 m2. If you write it with a formula, then it will look like this: 8 * 22 = 176 m2.

Among the customers who apply for the calculation of scaffolding for wall decoration, the question arises, what will be the price per square meter of the structure. Then the knowledge of a standard and rather simple scheme for calculating the area will come in handy.

The second method of determining a more accurate scaffold area involves taking into account the possible loads that the structure will be able to withstand. This is a fairly important criterion that allows you to select a material taking into account the required strength and stability of the structure:

• frames;
• racks;
• boards.

To find the value of the permissible loads, it is worth taking into account 3 main criteria.

1. The weight of the installers, plasterers, painters or other builders who will be standing on the platform.
2. The total mass of building materials that the structure will have to withstand as a result.
3. Transport system type. In the case of a tower hoist, it will be necessary to take into account a dynamic factor of 1.2 in the calculation. In all others, the standard load indicator will be 200 kg per box or wheelbarrow if the material is installed with a crane and 100 kg per load if it is carried by a worker.

It is worth noting that safety precautions only allow one level of the structure to be loaded. At the same time, the standards also determine the maximum number of people who can be on the platform. On average, there should be no more than 2-3 of them per flooring.

To calculate scaffolding, it is necessary to take into account both of the listed methods, with the help of which it will be possible to select the right material and determine its quantity, which will ultimately allow us to calculate the cost.

Example: scaffolding is required to help finish the facade of a building 20 meters high and 30 meters long. Solution.

1. First, you need to determine the total number of tiers. There will be 10 of them, since 10 * 2 = 20 meters.
2. Next, the number of spans along the length of the wall is determined. There will also be 10 of them, since 10 * 3 = 30 meters.
3. Then the total area of ​​the structure is calculated: 20 meters * 30 meters = 600 m2.
4. The next stage involves taking into account the possible load on the longline, which can be taken from the standards. The load depends on the type of work being carried out, the number of installers or other workers on the platform, and the total weight of the building materials. Depending on the data obtained, the dimensions of the sections of various structural elements are determined.
5. After determining the dimensions, they search for suitable elements in hardware stores or on the websites of manufacturers, determine the standard price and multiply it by the area.

The last three steps are necessary if you want to determine the cost of the structure in the case of ordering scaffolding or self-assembly of the structure. To determine the area without a price, it will be enough to use a calculation method that takes into account the height and length of the wall.
