Built to take any monitor, now and later

Imperial College London needed a way to make London construction sites cut their pollution, driven by residents’ complaints about air quality. The web app, Envimo, had to capture data from several different makes of pollution monitor from day one and take new ones as they came, so the first question was how to build something that would still fit in five years.

Four things we did

  • Intensive technical analysis so the design fits future development, not just the first monitors
  • Analysis of likely future requirements to understand the whole picture
  • Direct work with the third-party monitor providers on how their data is retrieved
  • An admin portal inside the application where users add and manage third-party monitor data themselves

The result is a well-built web application with a user-friendly interface and a design to match the brand.

Alerts to regulators and site owners across London

Envimo pulls data from air-quality monitoring stations positioned around construction sites and alerts regulators and site owners when a site breaches its limits. It is monitoring and reporting on dust pollution today, so sites act immediately to improve air quality, and it was trialled across several London boroughs. On the back of the trial Imperial won further funding to extend it into noise and vibration, with a wider London roll-out planned.

  • Live data from multiple makes of air-quality monitor
  • Breach alerts to regulators and site owners
  • Trialled across several London boroughs
  • Further funding won to extend into sound and vibration
  • Admin portal for adding monitors without a developer
