The aim of this Tender Notice is to:

  • Ensure we provide bidders with adequate information to determine if they wish to proceed with this tender event.
  • Provide NGN with a more detailed understanding of the interest within the market.

The Tender Notice process is the first stage of multistage procurement process. All interested suppliers must follow the below steps in order to proceed with the conditions of participation and PQQ stages of this procurement event:

Sign up or Sign in to NGNs Tendering Portal - Market Dojo. Follow this link to do so:

secure.marketdojo.com/signup ↗

When you have logged in to your dashboard, you'll need to click the 'Show all or enter invite code' button under the Event Invitations section.

You'll need to enter this code: 0FBCACB238

It will then notify NGN to approve you onto the tender event. Once approved you will be given access to the event, where you'll be taken to the Conditions of Participation stage, this stage is a pass/fail and will be locked until after the PQQ submission deadline. Any supplier who fails this stage will automatically be withdrawn from the process and will not gain access to the PQQ.

All suppliers who pass this stage will be automatically taken to the PQQ where they will be given a deadline and detail to complete.

Once the PQQ has been evaluated by NGNs internal evaluation team all those who meet the criteria will be sent to the RFP stage where NGN will assess against award criteria.
