CPV 4533 – Plumbing and Sanitary Installation Works

What does CPV 4533 cover?

CPV 4533 covers all plumbing, sanitary and heating installation works within buildings. This includes the installation of drinking water supply systems (cold and hot water), waste water and drainage systems, gas supply pipework, heating systems (radiators, underfloor heating, heat pumps, district heating connections) and sanitary fittings and fixtures. Industrial water systems, process pipework, fire-extinguishing systems (sprinkler systems) and solar thermal installations also fall within this area.

In the context of public procurement, plumbing and sanitary installation is one of the core trades in every building project and is regularly tendered as a standalone specialist lot. The requirements of the Drinking Water Ordinance (TrinkwV), DVGW technical rules, DIN 1988 series and EN standards govern the technical execution. Sanitary installation works are particularly significant in hospitals, care homes, schools and sports facilities, where extensive fittings requirements and hygienic standards must be fulfilled.

Public contracting authorities include state building authorities, hospital companies, school building authorities, municipal housing companies and sports facility operators. The increasing integration of heat pumps, solar thermal systems and waste heat recovery in the heating system, as well as sustainable water management concepts, are becoming central elements of modern plumbing tenders. Further information on the CPV system is available from the European Commission (SIMAP) and in Regulation (EC) No 213/2008.
