A look at how overruns at Brazil's Cup stadiums

Some examples of questionable costs that government auditors found in the building of Brasilia's stadium for the World Cup:

—Auditors allege that nearly one-third of the $900 million in costs for the stadium are fraudulent.

—The tab for transportation of pre-fabricated grandstands in Brasilia was supposed to be just $4,700 — but the construction consortium billed the government $1.5 million.

—$16 million was lost when Brasilia's city government inexplicably failed to enforce a fine against the consortium building the stadium despite a five-month delay in completion of the main portion of the arena.

—Materials worth $2.3 million were listed multiple times on bills.
