Site supervision is where most civil engineers start. And for a while, it is exactly where the real learning happens. Labour management, material scheduling, drawing interpretation, quality checks under pressure. The site is unforgiving and instructive in equal measure.
But it has a shelf life as a growth vehicle.
At some point, usually three to five years in, the trajectory flattens. The engineers moving into leadership are not necessarily better at reading drawings. They are better at reading contracts, managing clients, controlling budgets, and making decisions under financial pressure. That gap is not a technical one. It is managerial.
This is the moment most civil engineers seriously consider an MBA.
