Contracts signed and value contracted under each code, counted from Portugal's open register across every procedure type. Each row is the deepest code carrying data, because a whole division is credited with everything beneath it and would take the list.

## What the notices look like

Construction notices carry the heaviest documents in procurement: bills of quantities, technical specifications, site-visit dates that are often mandatory. Deciding early matters more here than anywhere, because a serious offer takes weeks to build and the mandatory site visit passes long before the deadline.

## Frequently asked questions

**Which CPV codes cover construction tenders?**

Construction procurement spans four CPV divisions: 45, construction work, which is the core; 44, construction structures and materials; 71, architectural, construction, engineering and inspection services; and 43, machinery for mining, quarrying and construction. A contractor watching only division 45 misses the design, engineering and materials procedures that precede and accompany the works themselves.

**Why are construction tenders so hard to monitor?**

Because the buyers are local by nature. National portals carry the large procedures, but the regional, state and municipal buyers who commission most public works publish on their own platforms, in their own language, on their own rhythm. That layer is exactly what a national-portal watch misses, and it is where the contestable volume for a mid-sized contractor usually sits.

Sector buyers mapped outside the national portals: 174.

## How contested it is, measured in Portugal

- 14.9% of open procedures drew a single bid
- 5.1 bids on average
- 2,500 open procedures behind these figures
- CPV 45, Construction work: 16.1% single bid across 1,607 procedures
- CPV 71, Architectural, construction, engineering and inspection services: 10.3% single bid across 478 procedures
- CPV 44, Construction structures and materials; auxiliary products to construction (except electric apparatus): 15.4% single bid across 415 procedures

Portugal publishes its complete contract register as open data, so competition is counted there rather than estimated. These are Portuguese figures for January to July 2026, covering only open procedures whose bidder list was reported; direct awards are excluded, because there the buyer chooses who bids.
