No more missing relevant tenders because of a wrong accreditation category. No more spending hours on specifications you do not qualify for. Find, assess and track construction-related public tenders — from a single platform.
Accreditations: the first filter that matters
In the construction sector, a selection mechanism exists that is found in no other industry: contractor accreditation. Without the right accreditation in the right category and class, you cannot bid — regardless of your experience or price. Category D (general contracting), C (road construction), P (electrical), each with classes from 1 to 8: these are the parameters that determine which contracts are within your reach.
In TenderWolf, accreditations are a full search dimension. You set your category and class as part of your search profile, alongside CPV codes, NUTS regions, keywords, form types and specific contracting authorities. The platform shows you only contracts that match your accreditation. That sounds simple, but it saves you daily sifting through dozens of notices that are not relevant to you.
Knowing quickly whether you may and want to bid
Construction specifications are technically complex documents. Beyond the accreditation requirements, they contain selection criteria you need to check: required references (comparable works of a specified scale), minimum annual turnover, safety certificates (VCA, BeSaCC), and sometimes specific technical capabilities.
The AI Quickscan reads the specification and extracts this information in a structured format: required accreditations, selection thresholds, award criteria with weightings, timeline, estimated value, lots. Instead of reading through the entire document, you have an overview in seconds that you share with your team and use for a GO/NO GO decision.
This is relevant for every contractor, but especially for smaller firms that need to be selective with their bidding capacity. One wrong call — writing a bid for a contract where you just fall short of the selection criteria — costs weeks of work.
Lots: opportunities for specialised contractors
Since the 2016 Public Procurement Act, contracting authorities must justify why they do not divide contracts above €143,000 into lots. In practice, this means many construction projects are split: structural works, electrical, HVAC, painting, finishing — each as a separate lot with its own accreditation requirements and selection criteria.
For specialised contractors, lots are a gateway to projects that as a whole would exceed their class. An HVAC specialist with accreditation D17/D18 in class 3 can bid on the climate lot of a major renovation project, even if the total project exceeds class 8.
TenderWolf shows which lots exist per publication, with their individual requirements. This way you spot contracts that match your specialisation and class, even when they are embedded in a larger project.
Knowing your competitors in the region
The construction sector is more regional than other markets. Contractors primarily compete with firms that are active at the same contracting authorities and in the same region. Through the company profiles in TenderWolf, you can see per contracting authority which contractors have previously worked there, which contracts they have won, and at what price.
In a sector where price is often the decisive award criterion, this gives you insight into what constitutes a realistic price level. For tenders with opening reports, you see the submitted amounts — you know not just who is bidding, but how they price.

Construction is physical and local, but not always limited to one country. TenderWolf covers Belgium, the Netherlands, Luxembourg, France and European above-threshold tenders alongside.
