The majority of May’s megaproject spending was attributed to the recent groundbreaking of the Taiwan Semiconductor Manufacturing Company’s new chip plant located in Phoenix, AZ.
The megaproject activity for the month transitioned manufacturing “from being among the five worst-performing subcategories YTD to now being among the top five best performers through May,” Guckes said.
“May’s megaprojects spending once again emphasized the importance of very large projects in the nonresidential construction market, accounting for
39% of the month’s total spending.”
