Safety is the top priority; the intern will gain experience with OSHA requirements, attend safety meetings, and help with compliance tracking and inspections, developing an understanding of risk management and proactive safety measures.
Delivering high‑quality projects with outstanding service is central to Thornton’s operations; the intern will support project teams by ensuring work meets design specifications, conducting site walkthroughs, and assisting in reviewing submittals and shop drawings to maintain the company’s reputation for exceptional delivery.
Community involvement is valued, and the intern may participate in outreach efforts or assist with company‑sponsored philanthropic events that benefit the neighborhoods where Thornton builds.
Empowerment is fostered by giving the intern opportunities to take initiative, contribute ideas, and collaborate with experienced professionals, including tasks such as assisting with RFIs, tracking schedules, and coordinating subcontractor meetings.
Accountability is emphasized through meeting deadlines, tracking progress, and ensuring precise completion of tasks such as logging permits, subcontract agreements, and assisting in project cost tracking, while also holding others accountable for deliverables.
Professionalism is essential in the fast‑paced construction environment; the intern will interact with project managers, subcontractors, and clients, learning to manage documentation, uphold ethical standards, and represent the company with integrity.
