BIM Benefits Quantified (Again)

Previous efforts on calculating benefits from implementing BIM were done by various universities, industry associations, so that’s probably why they were mostly ignored. It’s a pity we don’t respect our scientists! There was a good book published by IFMA (International Facility Management Association) in 2014 – “BIM for Facility Managers” that dedicated many pages to this topic: what is the Return on Investment (ROI) from implementing BIM for handover and facility operation & maintenance. The University of Southern California, ZHAW in Switzerland, and others published white papers showing significant benefits not only in cutting time needed for a work order, but also in improving risk management, extending life of serviced equipment, etc.

Well, now the situation may be better – PwC has used the sophisticated methodology to work out savings on two UK BIM projects, for the Department of Health and the Department of the Environment, and have used the results to extrapolate across the government’s capital spending programme. The report says: “Interpreting quantified benefit estimates across our two projects/assets – Foss Barrier Upgrade and the 39 Victoria Street Office Refurbishment – the gross total quantified benefits estimated were 1.5% and 3% of whole of life expenditure, respectively.

For the Department of Health refurbishment of 39 Victoria Street for example (pictured above), the report calculated that BIM-enabled savings accounted for £676,907. Of this, £42,366 was in design, £141,872 in construction and an expected £492,669 in operation over 12 years. As usual, the biggest savings identified are in the operation phase.
