## Summary

NPL Management Limited bought three broadband seismic sensors and associated monitoring equipment for precision measurement, vibration analysis and scientific research. The sensors are specified for a measurement range from 360 seconds to 100 Hz and sensitivity of 2,000 (2 × 1,000) V/m/s. The package includes handheld control units, power cables, sensor connection cables, packaging and delivery, alongside warranty support, technical documentation and manufacturer support. The equipment is intended for high-precision ground-motion, vibration and seismic monitoring in laboratory and field environments, including research, metrology, infrastructure monitoring and environmental measurement. The goods were delivered in the United Kingdom.

The procurement is complete and the contract is active. It was a below-threshold purchase using a procedure described as unknown, arranged as one lot. GURALP SYSTEMS LIMITED was selected as supplier. The contract was signed on 7 September 2026 and runs from 7 September to 30 December 2026. Its value is £5,041,250 excluding VAT and £6,049,500 including VAT. The award information does not state an evaluation basis.

This award demonstrates demand from NPL Management Limited for specialist broadband seismic sensing equipment, supplied as a complete package rather than sensors alone. A credible competitor for a similar requirement would need to provide sensors meeting the stated long-period-to-high-frequency measurement range and sensitivity, together with compatible handheld controls, power and connection cabling, packaging and delivery. The requirement also points to the importance of dependable measurement for laboratory and field monitoring, plus warranty provision, technical documentation and manufacturer support to enable installation and operation. Suppliers able to cover the equipment and its associated support as a coordinated supply would be well placed to compete when this buyer next sources the same kind of seismic monitoring equipment.

## Notice

Requires the supply and delivery of broadband seismic sensors and associated monitoring equipment to support precision measurement, vibration analysis, and scientific research activities. The requirement includes the provision of three broadband seismic sensors with a measurement range of 360 seconds to 100 Hz and sensitivity of 2000 (2 x 1000) V/m/s, together with handheld control units, power cables, sensor connection cables, packaging, and delivery services. The equipment will be used to undertake high-precision ground motion, vibration, and seismic monitoring within laboratory and field environments. The sensors shall provide reliable and accurate measurement capabilities suitable for scientific research, metrology, infrastructure monitoring, environmental measurement, and other applications requiring the detection and analysis of low-frequency vibration and seismic activity. The contract includes supply, delivery, warranty support, technical documentation, and associated manufacturer support services required to ensure successful installation and operation of the equipment.
