The table below lists both the RSMeans historical cost index based on
Jan. 1, 1993 = 100 as well as the computed value of an index based on
Jan. 1, 2017 costs. Since the Jan. 1, 2017 figure is estimated, space is left
to write in the actual index figures as they become available through
the quarterly RSMeans Construction Cost Indexes.
To compute the actual index based on Jan. 1, 2017 = 100, divide the historical
cost index for a particular year by the actual Jan. 1,2017 construction cost index.
Space has been left to advance the index figures as the year progresses.

Adjustments to Costs
The ″Historical Cost Index″can be used to convert national average building
costs at a particular time to the approximate building costs for some other time.
Example:
Estimate and compare construction costs for different years in the same city.
To estimate the national average construction cost of a building in 1970,
knowing that it cost $900,000 in 2017:
INDEX in 1970 = 28.7
INDEX in 2017 = 208.5
Note:The city cost indexes for Canada can be used to convert
U.S. national averages to local costs in Canadian dollars.
Time Adjustment Using the Historical Cost Indexes:
Index for Year A
Index for Year B
× Cost in Year B = Cost in Year A
INDEX 1970
INDEX 2017
× Cost 2017 = Cost 1970
28.7
208.5 × $900,000 = .138 × $900,000 = $124,200
The construction cost of the building in 1970 was $124,200.
Example:
To estimate and compare the cost of a building in Toronto, ON in 2017 with the
known cost of $600,000 (US$) in New York, NY in 2017:
INDEX Toronto = 110.6
INDEX New York = 134.6
INDEX Toronto
INDEX New York
× Cost New York = Cost Toronto
110.6
134.6 × $600,000 = .822 × $600,000 = $493,200
The construction cost of the building in Toronto is $493,200 (CN$).
