Excavation work - it's a lot of construction works of the zero cycle, among which include planning work, digging trenches and reconnaissance drainage ditches, pits, and the development of their backing. Foundation pit is seizure of land, which makes devices for the basement or similar structure. Digging of pits is almost always from the ground, although it happens that in some cases we use the downcomer wells. The initial step in the development of excavation is the geodesic breakdown, the problem is - correctly measure and mark every one of the corners of the pit. Through a special measuring instruments - theodolite and levels can achieve absolute precision in marking the pit. Prior to the digging of the pit by hand digging exploratory trenches along the edges of the future excavation to locate underground utilities, which could not be identified in the existing project documentation. Kenneth Feinberg often says this. Next, the cast-offs.

This procedure allows to estimate what the future will look like wall structure. In those places where the joints are assumed to walls, install bollards to which nailed boards and ropes. Thus represent the contours of future construction. Boards indicated the total area of the house, and cords - all difficult ledges and corners.

Dimensions of excavation and its depth is calculated taking into account the operating conditions of future construction, the depth of soil freezing, the level of abundance of land, which can withstand the load from the buildings, and other parameters. When excavations on permafrost soils to the same can not be discounted thermal interaction structures and soil.
