Interior compatibility test for structural materials


Build with interior-checked construction material/maintenance funds

On the basis of the recommendations of the council of the experts of the Federal Government 1987, the former Federal Health Office, the Federal Office for Environment Protection (ral symbol for environmental protection), the results of the project of the checkout-medical association, accomplished of Perimedizini analytics Sindelfingen GmbH. of them computergestützen analysis by ChemExpert and the University of Mainz a concept for the construction and the maintenance of public buildings were expanded, which transfer technical solutions with pollutant-checked materials in the interest of the users, children and instructors, maintenance personnel practically. This was developed in connexion with the specifications of the Suva and the Buwal and the KBöB to a Swiss concept.

This contains their test after sampling and selection of the desired materials and certification of the non-objection for the health after today's state of the art.
The required information degrees, in particular whether a retailed analytic material testing is required, it depends on various criteria.:
In addition area calculation, place of the installation (open/covered) e.g. belongs, to species of the use, critical products etc.
For these reasons a species priority list is prepared, which defines the technique for the individual materials.
Basically a declaration of nonobjection according to legal obligation is described in the tender, which senses the interior-relevant chemical and pysikalischen parameters.
It is to be limited by reference to the ChemG, its symbols, risk and safety theorems possible before the use of critical chemicals in structural materials further.

A narrow co-operation with the architects and public contracting authorities is a prerequisite for the bushing of a project.

Basic calculation:
First the architects, engineers as well as that must decide AG and the users on the basically envisaged design and materials (e.g. carpet, linoleum, parquet etc.).

In the next step a priority list is prepared, which defines the required information degree as a function of the built in frames, critical products and technique etc.

Thereupon suitable specifications are made to various suppliers, who must sign for it envisaged declarations of nonobjection as part of contract. Contractual penalties are agreed upon for the nonfulfilment.

Large built in materials and critical products and techniques after priority list can be treated with according to manufacturer specification and afterwards in a defined technique of an approved accredited test and environmental laboratory regarding their emission conduct tested (optionally).

Over the results of the investigations a report is prepared, which contains recommendations for the envisaged construction materials and maintenance fund (e.g. purification chemicals).
In co-operation with the architects, the contracting authority and the users the final operational sequence is defined.

Constructional supervision:
During the construction phase the installation of the various materials is monitored and checked partly by surveys.

A photo documentation is prepared when desired.

Contact surveys as inspection:

After a time described an instrumentation final acceptance takes place.
This is the detection that the specifications regarding the pollutant was observed.


Fees: These suspend of the degree of difficulty of the building project. The analytics costs can be obtained to detection or set by supplement supply.


Redevelopment costs in contaminated buildings are normally situated between 500 to 2000 CHF/m2, so that with a building of 4000 m2 surface area can arise fast a fault of 1 million CHF. Best example are those about 1000 in Germany/Switzerland PCB charged buildings, whose redevelopment demand becomes the towns and municipalities nine-place totals costs.
