In recent years, when it comes to construction sites, whether private or public industry, the lack of workforce has been a consistent problem. Matter of fact, this problem has been haunting Taiwan's construction industry for more than a decade. The reason for lacking of solution, or even the reason why there is a shortage of workforce, as well as the degree of shortage, have all been unsolved puzzles. As a result, this research aims to examine the current environment of Taiwan's construction workforce, and putting the main focus on rebar, template and concrete workers. Through interviewing experts, learning the situation of our nation's problem, this research generated a second phase of questionnaire, which included questions regarding current situation, reason, effect and solution on the problem of the shortage of workforce. The questionnaire was given out in 16 different cities in Taiwan.
