Supply, Installation and Maintenance of Air Quality Monitoring System

Description

This work package of the Liverpool City Region Combined Authority (LCRCA) is to supply, install and maintain (for an initial fixed period) air quality management sensors onto existing traffic signal poles at 37 key junctions and locations. The over arching requirement is that the sensors should have the ability to detect in real-time the levels of Nitric Oxide, Nitrogen Dioxide, Ozone and Particulate Matter (PM1, PM2.5 and PM10) and feed into the Local Authorities' traffic management systems via their 6 individual Siemens "Stratos" traffic control systems. The key factor for this work package is that the sensors will need to be capable of being fully integrated into Stratos systems that each of the 6 Local Authorities currently use to control their traffic signal and systems strategies The commission will include ongoing operational and maintenance responsibility of the sensors and system connections for a 5-year period. This should be priced into the upfront cost such that the LCRCA and Local Authorities will have no ongoing costs for maintenance and repair going forward for a 5-year period. (This will be with the exception of where damage has been caused by RTA or vandalism, following which additional repair / replacement costs will be agreed with the Service Provider.)
