Procedure

Procedure type

Competitive flexible procedure

Competitive flexible procedure description

The expected process for this procurement is set out below. Bidders should refer to section 2 of the Invitation to Participate and section 2 of the Invitation to Tender for further detail.

There will first be an Invitation to Participate stage where Bidders are invited to submit a Participation Submission (being a completed PSQ).

This is to enable the London Borough of Islington (the Council) to evaluate the economic and financial standing, technical ability and professional competence of the interested parties.

The participation stage will conclude with the Council shortlisting the three highest scoring Bidders (following the scoring methodology in the ITP), though the Council will reserve the right to shortlist the four highest scoring Bidders as set out in the Invitation to Participate.

The shortlisted Bidders (the Tenderers) will then be issued a formal Invitation to Tender.

The Council intends to hold a briefing session with each Tenderer to establish the expectations, requirements and process. The Council then intends to hold a number of dialogue meetings with the Tenderers to discuss their emerging proposals in respect to the award criteria before calling for final tender submissions.

Following evaluation of the final tender submissions received in accordance with the methodology set out in the Invitation to Tender, the Council will have identified the most advantageous tender. This being the tenderer whose tender achieved the highest score in accordance with the scoring methodology set out in the ITT (the Preferred Tenderer).

The Council intends to hold a ‘Preferred Tenderer stage’ with the Preferred Tenderer prior to entry into contract so as to clarify and confirm commitments made and for limited post tender negotiation, but it is expected that agreement will have been reached on all material issues before the call for Final Tenders.

The Council reserves the right to negotiate the Preferred Tenderer’s Final Tender whilst finalising the terms of the Contractual Documents, provided that this does not have the effect of:

• materially modifying key elements of the Final Tender;

• changing the scope or intention of the Final Tender; or

• distorting competition or causing discrimination.

The Council reserves the right to vary the process at any stage of the procurement.

Please note that the ‘contract start date’ and ‘award decision date’ included within this Tender Notice are estimates and may be subject to change.
