    Brief

    National Highways Ltd is establishing a framework to support the A122 Lower Thames Crossing project. This major infrastructure programme is transitioning to public funding through a Regulated Asset Base (RAB) model, with potential private sector involvement in construction and long-term operation. The framework seeks specialist technical consultancy, engineering advice, research and innovation across five key service areas: (1) Engineering and Standards, (2) Operations Maintenance, (3) Environmental Sustainability, (4) Customer Behaviour, Health & Safety and Communications, and (5) Planning Policy, Organisational Support & Governance. Services will cover roads, structures including tunnel design, highway infrastructure, operations, environmental sustainability, health and safety, plus evaluation and review of projects, policies, standards and post-implementation assessments. This is an opportunity for qualified suppliers to provide expert support to a nationally significant transport infrastructure project.
