CPV 511 – Installation of Electrical and Mechanical Equipment

What does CPV 511 cover?

CPV group 511 covers installation services for electrical and mechanical equipment and systems. This includes the assembly and commissioning of high-voltage and medium-voltage switchgear, transformers, generators, motor drives, pump drives, compressors, and mechanical transmission systems.

This group is particularly relevant for public utility companies, infrastructure operators and municipal energy suppliers. The installation of transformer stations, switchgear and power supply equipment for public buildings and infrastructure projects typically falls within this group. The assembly of emergency power generators, uninterruptible power supply (UPS) systems and network backup systems for public facilities is also tendered under CPV 511.

In the mechanical domain, CPV 511 covers the installation of drive systems, hydraulic systems, pneumatic systems and mechanical transmission equipment. The group is distinct from building installation works (CPV 453) in that it involves the assembly of independent mechanical and electrical systems – not building services installations forming part of a construction contract. The full CPV structure is available at the European Commission (SIMAP) and Regulation (EC) No 213/2008.
