CPV Code 4533, Plumbing Installation
What does CPV code 4533 cover?
CPV code 4533 (Plumbing installation) covers all plumbing and sanitary installation work in buildings. This includes drinking water installation (cold and hot water pipes, circulation systems), drainage installation (sewage and rainwater pipes), installation of sanitary fittings (WCs, basins, showers, urinals) and heating installation (boiler systems, heat pumps, underfloor heating, radiators).
Fire suppression systems (sprinklers), medical gas supply in hospitals and laboratory media supply in research facilities also fall under this scope. Plumbing is the second most important building services trade after electrical installation.
Who uses this CPV code?
Plumbing installations are tendered for virtually every building project. Particularly complex requirements exist for hospitals (medical gas supply, hygienic water installation), schools and nurseries, swimming pools (water treatment), sports halls and administrative buildings.
The bidder side comprises SHK businesses (sanitary-heating-climate) of all sizes. Many cover both plumbing and heating, calculating both trades together.
How does Patterno help?
Patterno HIT identifies plumbing tenders specifically and distinguishes between pure plumbing, combined SHK lots and specialised services like sprinkler systems or medical gas supply. SHK businesses can set differentiated profiles.
Patterno BID supports SHK bill of quantities calculation effectively. The AI agent prices piping items based on current material prices (copper, stainless steel, plastic), assembly times by diameter and installation method, and respective markups. The time advantage is particularly evident for extensive projects with several hundred piping items.
Energy transition and plumbing
The heat transition is a massive driver: replacement of gas and oil heating with heat pumps is being accelerated in the public sector. Many municipalities have launched climate protection programmes for replacing fossil heating in public buildings. For SHK businesses building heat pump competence, a growing market segment is opening up.
