Registration as pre-qualified company (PQ VOB)

In order to ease the placing of public contracts, the system of prequalification was installed in 2005 by the prequalification guideline of the German federal ministry for traffic, building and city development (BMVBS).

This upstream, placement-independent check of the suitability proofs by the requirements defined in § 6 VOB/A makes it easier for public purchasers to check a company’s suitability and enables companies to prove their suitability quicker and easier.

Because SOKRATHERM is also frequently working for public purchasers (e.g. municipalities or hospitals) we have applied for registration in the freely accessible prequalification list in 2009 and are registered with the PQ-number 110.000314.

Since then, SOKRATHERM is an officially prequalified company. The regularly updated documents of proof can be viewed in the password protected area at Further info about the prequalification system as well the freely accessible list of prequalified companies can be read on this website as well.
