Login2026 marks 65 years of BCIS supporting the built environment with trusted construction cost data.
Since 1961, our role has been consistent: helping the industry to base decisions on evidence rather than assumption, reducing pricing uncertainty and strengthening risk management across projects and portfolios.
From post-war reconstruction through to today’s digital-driven environment, our service has supported construction and insurance professionals, investors and asset owners to understand costs, benchmark performance and plan with greater confidence.
Over six decades, the industry has changed. So have we.
Our data, technology and methods continue to evolve to reflect new delivery models, sustainability priorities and emerging risks.
As we mark this milestone, we are reflecting on where we started, how the service has developed and what comes next.
