Interlocking and assurance
We retain end-to-end SSI capability in-house, from design and data through simulation and verification to principles testing, helping find errors in the office before they become site or operational risk.
Who we work with
We work with a wide range of clients, from Network Rail and Tier 1 and 2 contractors to manufacturers, design houses and operators, whether we are the Principal Contractor or supporting one. They come to us for specialist depth that is hard to find elsewhere, delivered with the agility of an SME: direct access to the engineers doing the work, and decisions made quickly.
