The United States is a high-cost construction market by global standards — it is the baseline our construction cost index is measured against (index 100). This page prices an apartment block — four floors, roughly 12–16 units, reinforced-concrete frame, common stair core — at 4800 m² of gross floor area, then breaks the cost down element by element so you can see where the money actually goes. Costs are quoted in USD for comparability; the local currency in the United States is USD ($), and a bill of quantities generated from your own drawings is priced in USD using the CSI MasterFormat divisions standard.

Why do build costs vary so much between countries?
+
Three things dominate: labour cost, how much of the material basket is imported, and the code requirements the building must satisfy. The United States sits at index 100 against the United States at 100, which is why the figures above differ from what you'd see quoted for the same building elsewhere.
