Construction Cost Inflation – Commentary 2019 ...
Divide Index for 2019 by index for 2013 = 109.6/86.0 = 1.27. Cost of building in 2013 times 1.27 = cost of same building in 2019. For future work, I would use the long term average idex for the type of work. See the very end of the post "Construction Inflation Index Tables" for the complete explanation of "How to use an index."
