Types of tendering

The procurement procedure followed by HHNK depends primarily on the value of the products or services to be purchased or the work to be carried out.Legislation and regulationsdetermine which entrepreneurs are admitted to the tendering procedure.

Threshold amounts for types of procurement

The tendering procedures we apply depend on whether the contract concerns works, supplies, or services, and on the estimated value of the contract. The table below shows the threshold amounts we use to select the appropriate procedure for a contract (all amounts are exclusive of VAT).

The procurement threshold is an amount set by the European Commission every two years.

Single private tender

HHNK approaches one company of its choice with the request for quotation.

Multiple private tendering

HHNK invites a limited number of companies, usually between three and five, to submit a tender. We select these companies based on a number of objective criteria. The contract is published onTenderNed, but is only accessible and visible to companies that we have approached for this tender.

National tendering

HHNK awards the contract to a company through a national procedure (public or non-public). An announcement of the contract is always published on TenderNed, which is only open to the Dutch market. This national procedure is similar to the European one but has shorter lead times.

European tendering

Above the European thresholds, HHNK must issue European tenders. These contracts are always published on TenderNed and are open to companies from all member states of the European Union (EU). Under certain conditions, they are also open to companies outside the EU (if they are affiliated with the EU through treaties). The most common procedures are: restricted, open, and competitive dialogue.

Requirements and criteria

Depending on the procurement procedure and the type of contract, certain requirements and criteria apply to tendering.

Comprehensive list of engineering services and works

When privately tendering engineering services and painting work, we use a wholesale list system. Market parties can register for one or more wholesale lists and are admitted if they meet oursuitability requirements. The document below explains exactly how it works, which wholesale lists you can register for, and which suitability requirements apply.
