About Asite
We start with a simple idea: the built environment should be smarter, safer and more sustainable. Everything we do is about helping the people behind major construction and infrastructure projects work together more easily and make better decisions.
Asite offers a cloud-based platform that connects project teams, improves collaboration and manages data from the first design to the final handover. Industry leaders such as Laing O’Rourke, Transport for London and Aldar use Asite to keep their projects running smoothly and delivering strong results.
With offices around the world and a record of steady, profitable growth, we are shaping the future of construction technology while supporting the people who build the world around us.
