General and procurement questions
Have you considered Early Contractor Engagement to reduce cost and risk? This can bring benefit to the project.
We have considered the approach of Early Contractor Engagement. For the Yellow Line civil works contracts, we have decided to base the procurement on the Swedish standard form of contract (AB04 or ABT06). However, for the TBM/Årstaberg contract, we plan to hold a dialogue with the qualified tenderers based on the preliminary tender documents, to gather their views on both technical and commercial requirements.
Could you please share the budget of each procurement package?
The estimated values of the procurements are presented in the procurement schedule (see column L), which is updated quarterly and published on our website.

Hello. Only the companies with certain product codes in TransQ will get the invitation to prequalificacion. Are you going to inform about the product codes needed to get the invitation?
The applicable TransQ product codes for each procurement are specified in the procurement schedule (see column G), which is published on our website:
Swedish version, see the following link: https://nyatunnelbanan.se/aktuella-upphandlingar/
English version, see the following link: https://nyatunnelbanan.se/en/current-procurements/
Are the invitations going to be sendt via TransQ? Can you say which product codes must be offered by the contractor so as to receive the invitation?
No, invitations to participate will not be sent via TransQ. They will be issued through the Client’s electronic procurement system (currently tenders are handled in Tendsign.com, and will later move to eAvrop.com). Invitations will only be sent to suppliers that are successfully prequalified through TransQ where this applies.
The procurements for which the TransQ prequalification system is used, including the applicable product codes, are specified in the procurement schedule (see columns F and G), which is updated quarterly and published on our website:

What procurement system are you using? Mercell TendSign or E-avrop?
For the moment we are using Mercell Tendsign marketplace for publishing of procurements. But we are in currently in a transistion-phase to shift over to e-Avrop in nearly future.
Procurement for ”77051 Station Östbergahöjden” is out on ”E-avrop” but I can’t find it in the Excel on your webpage: https://nyatunnelbanan.se/aktuella-upphandlingar/
Procurement 77051 Preparatory work, Östbergahöjden Station is reported in the procurement schedule (see line 5), which is published on our website:

Does the procurement framework allow a contractor, or a consortium of contractors, to bid for and potentially be awarded multiple packages? If so, how can the Client best leverage the reduced interface risk that comes with a more integrated delivery approach? Indeed, fragmentation inevitably increases the number of interfaces. To what extent is the Client prepared to explore alternative, more streamlined procurement strategies?
We are currently not planning to carry out combinatorial procurements, where one contractor or consortium could be awarded multiple contracts. The packaging and sequencing of the procurements have been structured to secure competition, manage project interfaces effectively, and align with the overall schedule for the Yellow Line. Each procurement will be launched as soon as the necessary conditions for implementation are in place. If changes however occur in the scheduling, the client reserves the right to introduce combinational procurement where appropriate.
When will it start?
The Station contracts like Drill and Blast kontract for Östbergahöjden will be published at the end of december 2025, see teh procurement schedule on our website.

What do you mean about cooperative work mode in TBM procurement? Is it gonna be a dialogue process? Or a collaborative process like alliances in Nordic Countries? Is it gonna be a pure design & build contract?
The TBM contract will be a design and build contract based on the Swedish standard form ABT 06. We will apply a cooperative work model, which is a structured and partnership-oriented way of working between the parties, aimed at improving productivity and project outcomes.
The procurement will include a dialogue phase under a Preliminary Procurement Document (PUD) procedure. This allows the qualified tenderers to review and comment on the preliminary tender documentation in a structured manner before submitting their final tenders.

Regarding Guarantees: For the performance guarantees under ABT06, you named bank guarantees. Please also point out to the contractors that you are also fine with guarantees issued by Insurance companies with international rating.
