Simonson urged Congress not to let construction funding for highways, transit and airports lapse.
"Congress and the White House need to make these programs a priority, along with long-term funding for drinking water, wastewater and waterways," he said.
The group also noted that homebuilding increased from levels last year.
Simonson said the homebuyer tax credit had a profound effect on his industry. New, single-family home construction in May soared 31 percent from levels a year earlier while new multi-family construction, like condos or rental housing, tumbled 57 percent.
"The first-time homebuyer tax credit that expired at the end of April boosted demand for single-family and lessened demand for multi-family," he said. "Those distortions have now ended, although Congress voted to extend the closing deadline until Sept. 30 for families that have signed contracts by April 30."
