Despite an increase in total construction spending in December, officials at the Associated General Contractors of America warn that tariffs could fuel inflation and temper demand for new construction.
“Despite declines in a few segments, construction demand remains relatively strong,” said Jeffrey Shoaf, CEO, in a statement. “But increasing the cost of a range of construction materials will prompt contractors to raise bid prices, potentially undermining future demand for projects.”
The recently released AGC of America/Sage 2025 Construction Hiring & Business Outlook revealed that potential tariffs and their impacts on materials prices were among construction firms’ top four concerns in 2025. Any tariffs that are ultimately put in place with trading partners, including Mexico and Canada, are likely to increase the costs of construction and harm construction employers who are forced to absorb cost increases because they are locked in contracts, sometimes that were signed several years ago, according to the association.
“We are working with the Trump administration to explain the negative impacts of inflation has had on our industry, particularly these few years,” Shoaf said. “Hopefully the administration will be able to rapidly resolve the underlying concerns driving the new tariffs so our members can help build an even stronger economy.”
