According to Associated General Contractors of America (AGC), in the past two years, construction costs appear to be rising faster than the general rate of inflation.
Heavy construction in the U.S. and rapid growth in Asia have created a strong demand for a number of construction materials.
"The impact of the hurricanes has shown up most dramatically in the cost of diesel fuel and natural gas," says Ken Simonson, chief economist for AGC.
Inflation of diesel fuel impacts contractors most. "It's important to contractors because not only do they use diesel fuel to power their own construction trucks, concrete mixers and cranes, they also pay a fuel surcharge on deliveries to their job sites," Simonson says.
Simonson recommends coping with inflation prices by staying in contact with suppliers and keeping the homebuyer informed.
