WICHITA, Kan. (AP) — A survey finds that many Kansas contractors are having trouble filling skilled jobs in the construction industry. The survey is by the Associated General Contractors and was released Wednesday. Ninety percent of the 20 Kansas firms that participated in the survey say they're having a hard time finding project managers, engineers, welders, plumbers and carpenters. An Associated General Contractors economist says Kansas isn't the only state experiencing a shortage of people applying for construction jobs. He notes that other states like Texas and Louisiana are seeing fewer job applications too. The Wichita Eagle reports that the construction industry is seeing its skilled workforce age and retire. Many construction workers also have left the industry after being laid off in 2008 and 2009.
