Exploratory Research into the Adaptation and Implementation of the Magnetic Main Flux Method (MMFM) for UK Bridge Infrastructure

National Highways, the government-owned operator of the UK strategic road network, is seeking exploratory research into the Magnetic Main Flux Method (MMFM), an advanced non-destructive testing technique for detecting internal corrosion, wire breaks and deterioration in bridge cable systems, particularly in aging suspension, cable-stayed, prestressed and post-tensioned concrete structures. The research aims to technically validate claims that MMFM works through protective layers such as cement grout, galvanisation, coatings, HDPE sheathing and wax, and to assess its adaptation to UK environmental and operational conditions. This is a preliminary market engagement notice under the Procurement Act 2023; it is not a call for competition and commits National Highways to no future procurement.
