## Summary

National Highways Limited has completed the procurement process for the "Exe viaduct monitoring" contract, classified under architectural, construction, engineering and inspection services. This contract, valued at £320,000, was awarded to Mistras Group Limited for monitoring and analysis services of an acoustic monitoring system installed inside Exe Viaduct. The procurement method used was a limited negotiated process without the prior publication of a contract notice. Key dates include the contract being signed on 12th November 2021, with the process fully addressed under Public Contracts Regulations 2015.

This tender represents a significant opportunity for businesses specialising in structural health monitoring and maintenance, particularly those with expertise in acoustic monitoring systems. The unique nature of the contract, which restricts maintenance and repairs to Mistras due to proprietary technology, suggests that businesses with innovative monitoring solutions could look towards similar contracts in future needs for bridge monitoring and structural analysis, potentially collaborating with established suppliers or focusing on research and development to meet such requirements.

## Notice

This is a Voluntary Ex Ante Transparency (VEAT) notice informing the market that National Highways Limited (NHL) intend to award a contract without prior publication of a call for competition. NHL is entering a contract with Mistras Geroup Limited (Mistras) for monitoring and analysis services for previously installed Mistras proprietary sensor equipment. Under the contract, Mistras will monitor an acoustic monitoring system inside Exe Viaduct to provide 24hr monitoring of the external post tensioning cables following the finding of post tensioning cable failures.

### Lot Information

Lot 1

Monitoring an acoustic monitoring system inside Exe Viaduct to provide 24hr monitoring of the external post tensioning cables following the finding of post tensioning cable failures.

### Procurement Information

In 2016 Mistras installed an acoustic monitoring system (AMS) costing approximately PS0.5 million inside Exe Viaduct to provide 24hr monitoring of the external post tensioning cables following the finding of post tensioning cable failures. The original installation works were competitively tendered and Mistras were the only tenderers who quoted. The contract protects their rights for system and data analysis. Safe guarding works have been undertaken to protect the bridge structure but underlying corrosion issues in the remaining post tensioning remain and will not be rectified until a major scheme is undertaken under the National Highways Road Investment Strategy 3 from 2026. The AMS is an integral part of the safe guarding system for monitoring the bridge until the major scheme is undertaken. There are 72 sensors in each box, totalling 144 sensors across the bridge. This system provides a real time picture of the structural health of the bridge and safeguards us from potential catastrophic collapse. This Voluntary Ex Ante Transparency (VEAT) notice directly awarding a contract without prior publication is to allow National Highways Limited (NHL) to continue to use the AMS to obtain real time data of the structural health of the bridge. The current system has been assessed to meet the needs of the business and NHL does not wish to seek to procure an alternative solution. The system does have to be maintained and repaired by the provider, Mistras Group Limited (Mistras) and this contract will ensure NHL continue with the latest version of the system and the necessary technical support required should issues arise. NHL considers the award to Mistras is permitted by regulation 32(2)(b)(ii) of the Public Contracts Regulations 2015. The AMS has been designed by Mistras and they hold the intellectual property rights for it. Consequently no other Contractor can carry out maintenance, repairs or analysis of the system. They also maintain a live up to date webpage and analysis of the readings.
