Excavation

This article or the following section is not adequately provided with supporting documents ( e.g. individual evidence ). Information without sufficient evidence could be removed soon. Please help Wikipedia by researching the information and including good evidence.

Under excavation refers to the (for the purpose of a construction project) from the building excavated soil.

Excavated earth occurs in large quantities in the development of residential areas as well as in road and mining work . It does not count as building rubble and must be disposed of separately. If there is no earth excavation collection point in the area, z. B. earth excavation can be brokered via the Chamber of Commerce and Industry ( IHK ) earth excavation exchange or you have to have it picked up by private disposal companies for a fee .

description

Excavated earth occurs, for example, when excavating basements or leveling levels when building foundations (development of residential areas) as well as during roads and mining work. Excavated soil includes all different types of soil such as sand, clay, clay, and gravel. According to the Federal Soil Protection Act (BBodschG) and the State Working Group on Waste (LAGA), topsoil is a special case. When disposing of excavated earth, it is not its structure but its condition that plays a role. A distinction is made between unpolluted excavated earth and contaminated soil. The excavated earth is considered contaminated as soon as it is interspersed with roots, branches, or discarded packaging waste. It is considered polluted if the floor is inseparably contaminated by heavy metals or toxins such as acids and alkalis.

Recycling

Excavated soil that is not contaminated with pollutants can be reused without restriction for construction measures after thorough sifting out of larger stones (for example as sealing material in landfill construction or as insulation material for flood protection).

Contaminated and polluted soil may still be used to a limited extent after a microbiological decontamination wash, depending on the level of pollution. However, special protective provisions apply to the topsoil (humus-rich topsoil). Due to its high organic content, it is not suitable for building purposes, as it is not sustainable for buildings and rotates quickly. However, it finds its place in agriculture and horticulture.

Legal classification

If a building project produces more than 200 m³ of excavated earth, a complete soil analysis is mandatory in Germany. According to the Waste Catalog Ordinance (AVV), excavated earth and soil material can be found under the following waste catalog key:

• Waste from gravel and broken rock as well as waste from sand and clay ( AVV 01 04 08 and AVV 01 04 09 ). This is about excavated earth that has arisen during the extraction and processing of non-metallic mineral resources.
• Soil as construction and demolition waste ( AVV 17 05 ) This is soil (including excavation from contaminated sites), stones and dredged material.
• Soil and stones from garden and park waste ( AVV 20 02 02 ). This includes floor waste from domestic household waste and similar commercial and industrial waste.

Under contract law, the excavation from the construction and demolition waste area is passed on to the executing construction company when the construction project is awarded through the predominant tendering practice, which is also responsible for the professional disposal or recycling in the following step. In the Building Code (BauGB), general statements are made about the careful handling of soil, according to which, according to § 1 No. 7, the "concerns of environmental protection [...], in particular [...] of the soil including its raw material deposits [...]" must be taken into account. The protection of the topsoil from waste is also anchored here (§ 202). The Federal Mining Act contains a general obligation to deal with excavated earth; the Federal Immission Control Act formulates basic obligations for the proper and harmless recycling of residues.
