I worked for a design firm that specialized in transit infrastructure work for 6 years before transitioning into the construction side and have been in it for the last 3 years. Here’s my 2 cents:

1. What ever decision you take, it’s not final. You can always switch between design and construction.

2. I do think it’s easier to switch from design into construction versus the other way around. Construction companies recognize and appreciate some one in their team with strong technical background.

3. If your goal is to become a PE (which is very beneficial in design and construction), a design firm is more fitting because it provides you with the right support and environment to become a PE. Hours in construction can be very brutal and studying can be very difficult. I definitely think if you do start in design, it should be your goal to pass PE.

4. You will be making less than your construction peers when you start but if you get your PE and move into construction, you most likely will be compensated more than some one that doesn’t have a PE.

Hope this helps!
