Who buys under it

Metropolitano de Lisboa, EPE1

Portugal publishes its complete contract register as open data, so this is counted rather than estimated. January to July 2026. The count and the value cover every procedure type; the bid figures cover open procedures only, because in a direct award the buyer chooses who bids. A mean is published from 10 open procedures up and a single-bid share from 30, so a rate on this page always rests on enough of them to mean something. All 25 divisions ranked.

The market this code sits in

Construction and public works1,671 codes across 4 divisions, and the buyers who publish under them.

Buyers tag their notices with CPV codes, and mis-tag them often enough that a code-only alert misses real tenders. TRINTA's radar reads the notices themselves, in their own languages, and scores each one against what your company actually sells, so a procedure filed under a neighbouring code still surfaces when the text fits.
