The ability and experience of suppliers in undertaking design optimization activities, and capacity to deliver the main works scope are important considerations for this opportunity. It is anticipated that the current value of this package is circa. £70m, which BBVS expect to value-engineer through design optimization.

Respondents to this opportunity should be advised that shortlisted applicants will be invited to tender through an external ERP system.

The exact scoring criteria are currently being developed by BBVS, and shortlisted suppliers will be invited to register for the ERP system in due course.

What is clear at this stage is that tenders will be scored competitively across a range of criteria, such as, but not limited to: Commercial, Programme, Methodology, HSEQ, Capability and Capacity.

BBVS are currently exploring the potential for early contractor engagement to optimize the existing RIBA 4 design. The experience of suppliers in undertaking design optimization, and ability to meet this requirement is also likely to be factored into the scoring criteria.

In 2018, Balfour Beatty, VINCI and Systra (BBVS) created a strategic alliance to deliver major infrastructure projects for HS2, in particular the Terminus at Old Oak Common.

BBVS are committed to delivering this project to align with the key principles of Integrity, Leadership, Respect & Safety.
