Many mid- to large-size construction firms have dedicated intern programs for college students, and they're often a pipeline for permanent hires (they know what they're getting based on the internship). They often ramp up for the spring-summer-fall construction season so you may have missed that window (they start taking applications after Christmas and New Years). Still, it's worth looking into. Larger firms often work on bigger projects that need a lot of manpower at all experience levels. I'm not sure if you're looking to get into the transportation construction business or the buildings end of construction.You might also try your state DOT and even county and city engineering departments. Some have intern positions in their budgets and they may also have a number of entry level tasks related to construction oversight and observations that are perfect for interns.If you haven't already, try your school's placement department - they can be very helpful and have good contacts. Also, consider looking geographically in warmer/southern areas if you're hitting too many dead ends - construction is obviously less seasonal in warmer climates. One of my son's friends was a construction management major - he worked one or two internships in the Cleveland (OH) area and one or two additional ones in one of the southern states, and he relocated after graduation for a position in one of the southeastern states.Good luck!
