The RLB Construction Cost Relativity Index identifies the relative cost of constructing similar buildings across the globe. The index is based on the local costing of standard building models and baskets of goods.

These are costed globally, and within regions, using the same quantities and similar specifications. They are costed in local currencies and relativities are calculated using a combination of statistical methods, including:

• Conversion into one currency by converting local currency model costs using USD and the International Monetary Fund’s published Purchasing Power Parity figures.
• The RLB Relativity Factor, a weighted sum of ‘one currency’ results.

The resultant index highlights the relative levels of construction costs between key global cities at Q2 2024.
