The ongoing expansion project at Edmonton International Airport (EIA) in Canada is estimated to reach a final cost of C$750m (US$725m), 25% under its original C$1bn (US$966m) budget.
EIA vice-president of infrastructure and technology Paul Garbiar said the economic downturn had made a good supply of workers available, kept labour costs down and made the project more efficient.
Garbiar said the project, which began in 2009, was on schedule and would be complete by 2012.
The expansion will add 480,000ft² to the current terminal, 13 new aircraft gates, a new control tower, an office building and a large concrete apron for aircraft movement.
The airport currently handles 6.1 million passengers a year and is expected to accommodate nine million annually by 2015 as a result of the expansion.
A new larger US departure and arrival space will also open to handle trans-border traffic, and new customs and immigration areas.
The project is being funded by Alberta Capital Finance Authority, according to edmontonjournal.com.
