Broken of the foundation plan: how to do it yourself

The breakdown of the foundation is the process of transferring the foundation schemes that were indicated on the drawings of the design documentation for the construction of the building. Such a breakdown is carried out using a clogging. Before you start the process of breaking, you need to prepare the place where the foundation will be laid, its surface should be flat, the vegetation must be removed, and the required building materials should be arranged in strategically convenient points.

First of all, you need to determine the extreme angular points of the house. Most often, on design schemes, the house is attached to the red lines of development of the site. Using this line as a guideline, the parallel axis of the facade is determined, after which it is possible to put two angular points that coincide with the width of the house. Having determined points, you need to fix them on the ground with pegs.

Then, using such a geodetic device as theodolite, from one of the pegs you need to organize a right angle and, having drawn another axis along the length of the house, put the third pegs. If theodolite is unavailable, you should knock down the wooden angle and with the help of it and the rope determine the third control point, then put the fourth pegs in exactly the same way. Now you need to measure the diagonals between the pegs, and if the numbers coincide, then everything is done correctly. The breakdown of the foundation is determined, which means that you can start working on Obska.

The future foundation is raised around the perimeter with pillars at a distance of about one and a half meters from the future walls, horizontal boards are nailed to poles at a height of about a meter. The distance must be withstanded so that when digging the foundation of the pit under the foundation of the cloak is not broken. Then carefully above the pegs you need to pull the cord from one cast -up to another opposite to it. So we get the perimeter of the foundation. We suspend the plumb line on the intersection points and get the verified points of the intersection of the axes of the walls of the house. Now you can start digging a pit and lay trenches.

The main one here is to carefully ensure that the walls are at right angles to each other. The main way to double -check this is the frozen diagonals, which should perfectly match.

Of course, the described scheme is suitable only for standard rectangular houses. In the case of any architectural complications, the process of breaking the foundation is also proportionally complicated.
