B+ G will guide you and help you define your spoil management concept according to the laws in your country.
In Switzerland, excavated materials are legally spoken waste, since they are not exploitated for the intended purpose (USG Art.7-6).
Moreover, the pollutor is responsible for the waste disposal which "...includes its recovery or deposit in a landfill as well as the preliminary stages of collection, transport, storage and treatment. “Treatment” is any physical, chemical or biological modification of the waste." (USG Art.7-6bis).
Finally, the production of waste should be avoided wherever possible and certain
types of waste have to be recovered if " this is economically feasible
and harms the environment less than other forms of disposal and the manufacture of new products." (USG Art. 30d).
In any cases, the client has to test different recovery possibilities for his excavated materials.
A spoil management concept has to be formulated in accordance to the following laws, ordinances and guidelines (since english is not one of the federal languages, the titles are given in german):
Since 2021 B+ G supports a consortium for the tender of the material management lot. Based on our experience, the raw material is continuously tested in the construction site's own laboratory.
Concrete tests with sulphate-containing aggregates (produced from tunnel excavation) and special binders were carried out in the Modane intermediate attack on 7 April 2016.
Among other things, the sulphate resistance is to be investigated.
The new Spitallam dam in the Bernese Oberland will require around 200,000m3 of concrete. The mass concrete consists of a maximum grain size of 125mm! A gravel plant was built for the production of the aggregates. B+ G supports the client KWO in the quality of raw materials, aggregates and concrete.
