Materials Prices Soar 20 Percent In 2021 Despite Moderating In December; Most Contractors In Association Survey List Costs As Top Concern In 2022


Construction Officials Say Biden Administration’s Plan to Double Tariffs on Canadian Lumber, Leave Other Ones in Place will Undermine Efforts to Address the Rapid Inflation in Key Materials Costs

Prices of construction materials jumped nearly 20 percent in 2021 despite moderating in December, according to an analysis by the Associated General Contractors of America of government data released today. Association officials said contractors rate materials costs as a top concern for 2022, according to a survey predicting the industry’s outlook for the industry the association released yesterday.

“Costs may not rise as steeply in 2022 as they did last year but they are likely to remain volatile, with unpredictable prices and delivery dates for key materials,” said Ken Simonson, the association’s chief economist. “That volatility can be as hard to cope with as steadily rising prices and lead times.”

In the association’s 2022 Construction Hiring and Business Outlook Survey, material costs were listed as a top concern by 86 percent of contractors, more than any concern. Availability of materials and supply chain disruptions were the second most frequent concern, listed by 77 percent of the more than 1000 respondents.

The producer price index for inputs to new nonresidential construction—the prices charged by goods producers and service providers such as distributors and transportation firms—increased by 0.5 percent in December and 19.6 percent in 2021 as a whole. Those gains topped the rise in the index for new nonresidential construction—a measure of what contractors say they would charge to erect five types of nonresidential buildings, Simonson noted. That index climbed by 0.3 percent for the month and 12.5 percent from a year earlier.

Prices moderated for some construction materials in December but still ended the year with large gains, Simonson observed. The price index for steel mill products rose 0.2 percent in December, its smallest rise in 15 months, but soared 127.2 percent over 12 months. The index for diesel fuel declined 5.3 percent for the month but increased 54.9 percent for the year. The index for aluminum mill shapes slid 4.9 percent in December but rose 29.8 percent over 12 months, while the index for copper and brass mill shapes fell 3.3 percent in December but rose 23.4 percent over the year.

Some prices accelerated in December. The index for plastic construction products climbed 1.3 percent for the month and 34.0 percent over 12 months. The index for lumber and plywood rose 12.7 percent and 17.6 percent.

Association officials said rising materials prices threaten to undermine what is otherwise a strong outlook for the construction industry in 2022. They urged the Biden administration to reconsider its plans to double tariffs on Canadian lumber and leave other trade barriers in place that artificially inflate the costs of key construction materials.

“Making lumber and other materials even more expensive will not tame inflation, boost supplies of affordable housing or help the economy grow,” said Stephen E. Sandherr, the association’s chief executive officer. “Instead, the administration should be removing tariffs and beating inflation.”
