Lending our Support to Mergen Consortium

David A Graham Associates Joins Elite Consortium for TfL’s TPIMES Framework

We are delighted to announce that David A Graham Associates (DAGA) Ltd has joined a specialist consortium called MERGEN , led by renowned vehicle safety expert Dr. Alix Edwards, to bid for the Transport for London (TfL) TPIMES Framework.

Bridging the Gap Between Vehicle and Infrastructure Safety

This partnership represents a unique synergy in the road safety sector. While Dr. Edwards’ team has been at the forefront of developing TfL’s Bus Safety Standard since 2016, David A Graham Associates brings the essential Road Safety Audit (RSA) and Engineering accreditation required to deliver safe, compliant infrastructure for the capital.

Why an “Expert-Led” Approach Matters

In a shift away from the traditional model of large-scale consultancies—where work is often delegated to junior staff—this consortium is built on a foundation of independent experts, micro-organisations, and leading universities.

By joining this group, David A Graham Associates ensures that TfL has direct access to:

• Accredited Senior Auditors: Providing the technical rigour required for Road Safety Audit Stages 1–4.
• Deep Domain Knowledge: Combining vehicle safety research with “on-the-ground” highway engineering and collision analysis.
• Agile Expertise: Delivering high-level insights directly from career-specialists who understand the complexities of London’s evolving transport network.

A New Chapter for London’s Road Safety

As London continues to push toward its Vision Zero goals, the integration of vehicle safety standards and highway engineering has never been more critical. David A Graham Associates is proud to lend its expertise to this consortium, ensuring that the next generation of TfL projects are scrutinised by the best in the business.

“We are thrilled to collaborate with Dr. Alix Edwards and this group of distinguished experts. Our goal is to provide TfL with a level of senior-led safety expertise that is often lost in larger corporate structures.” — David A Graham, Director of David A Graham Associates.
