Manufacture, supply and maintenance of ST CRIDs

There will be an ongoing demand for ST-Crids, circa 4,000 units, to cover the requirements of TfL across its Network and into the future. This requirement covers the following elements: 1. Annual Test & Calibration 2. Maintenance & Repairs 3. Supply of New Units Due to the nature and age of the ST-Crids, ongoing reviews to capture obsolescence and new design changes and ensure continued value for money for TfL, therefore the need for an updated partnership strategy may be required.
