What is a general contractor internship?

General Contractor Internships are temporary positions designed for students or recent graduates to gain hands-on experience in the construction industry.

As a General Contractor Intern, you can expect to assist with project coordination, site supervision, and communication between subcontractors and clients. Your daily tasks may include attending project meetings, reviewing blueprints, conducting site visits to monitor progress, and helping to ensure safety compliance. Interns often gain hands-on experience by shadowing experienced contractors, learning about budgeting, scheduling, and problem-solving on active job sites. This role offers a valuable opportunity to understand the workflow of construction projects and develop professional relationships within the industry.
