DENVER - The price of expansion plans at Denver International Airport is growing again.
The airport is adding a hotel and conference center, public plaza and light rail.
Initial estimates for the project were $650 million for phase one. However, airport officials changed the design to cut the budget by $150 million to $500 million.
A change that caused Spanish "star-chitect" Santiago Calatrava to leave the project.
Now the price is creeping closer back to the original price.
Officials at Denver International Airport have told city council the cost of a terminal redevelopment project has risen by $44 million and could go higher.
Airport officials say the project is now expected to reach $544 million.
According to the Denver Post, officials are blaming the rising costs on a competitive market for builders and problems with poor soil conditions that have led to frustrations for the contractors.
