Out of the total of 53,426 Mio CHF, new construction holds most expenditure with 61%,
especially in house building (66% of all construction activities). Public maintenance activities
account for only 8%. Expenses in new traffic and communication constructions are expected
to decrease in support of reconstruction, enlargement and demolition since the national grid is
more or less planned and finished. This fact can be confirmed with the increase of 14% of
investments in reconstruction, enlargement and demolition of traffic and communication
constructions. Public maintenance activities don’t cost much because only small activities
such as new coating or snow clearance are included in this category. About 2/3 of the
investments are made by private awarding authorities, the other 1/3 by public awarding
authorities (calculated for normed figures to the year 2000). This fact is important to know
which stakeholders are influencing which sectors most.
Flows and stocks
This section describes general volume stocks in house building. Existing networks and
constructions were compiled for civil engineering. After that, flows and stocks are
concretized for different materials.

Stocks in constructions
In 2007, there were 168 t of construction materials stocked per habitant. As we will see in the
next chapter, the construction period has a great influence on the type of materials
incorporated and therefore for waste management. The following figure shows the inventory
volume in Mm3 of Swiss buildings in different time periods. Please note that data represent
the whole building volume, including not only materials but also room volume. The periods
