The air quality monitors are located around the UK within the Zones and Agglomerations and are housed in standalone enclosures of varying sizes. A supplier is required to lead project management and delivery of new construction works for Air Quality Monitoring sites for circa 70 sites over the next 2 years. The project requires flexibility hence the extension years until 2029, as the delivery timescales are challenging.
