BAKU, Azerbaijan, September 17. Materials
represent approximately two-thirds of Türkiye's construction cost
index.
This is according to data released by the Turkish Statistical
Institute (TÜİK).
"Material index increased by 1.28% and labour index increased by
0.92% compared with the previous month," TÜİK said in its July 2026
report, adding that the two sub-indices increased by 27.13% and
30.51%, respectively, over the past year.
As TÜİK does not publish the exact weighting of materials and
labor in the overall construction cost index, Trend's calculations use the
relationship between the growth rates of the sub-indices and the
overall index to estimate their implied shares. The calculations
indicate that materials account for approximately 64% of the
overall construction cost index, while labor represents the
remaining 36%.
The estimated weighting remains broadly consistent when
calculated using both monthly and annual changes, providing an
additional cross-check of the result.
Trend's
calculations also show that materials account for an estimated 63%
of the building construction index and approximately 67-68% of the
civil engineering index. The difference indicates that the
composition of construction costs varies between building
construction and civil engineering projects.
For reference, this estimate is independently calculated by
Trend based on the relationship between each sub-index's growth
rate and the overall index's growth rate. It represents an
approximation and does not reflect TÜİK's official weighting
methodology.
