Fonn Construction site-management software
Published 21 March 2023; updated 21 September 2026; 2-minute read. Fonn Construction combines a web app for office staff with a mobile field app, giving project participants access to current drawings, plans and BIM models on computers, tablets and smartphones. Teams can communicate by phone or instant messaging; communications are stored for liability records. The page says up-to-date shared information can reduce misunderstandings, delays and rework.
Fonn estimates its tool could lower total project construction costs by about 18%, while reducing material consumption and transport to/from construction sites. The company frames this against construction-industry productivity challenges and cites USD 13.2 billion spent on US rework in 2018 due to inadequate project data. Market context in the article includes USD 10 trillion in annual global construction-related spending and a McKinsey estimate of USD 1.6 trillion in potential value from improved productivity (historical data).
The article says Fonn was used by construction companies worldwide and had 50% market share in Norway; it also states Fonn was acquired by the UK-based Access Group in May 2025.
