Both serve different purposes. Internal HR handles compliance, onboarding, and retention systems well. A specialized construction recruiter solves a different problem: speed and access to scarce talent. Senior roles like project managers, estimators, superintendents, and project engineers are hard to fill because qualified candidates are rarely active on job boards. Amundson Group maintains a network of 90,000+ construction professionals across heavy civil, site development, data center, rail, tunnel, and wastewater work, and delivers a first qualified resume within an average of 7 hours of job intake. Your HR team handles culture fit, benefits conversations, and long-term retention. The strongest hiring programs use both. Recruiters close the urgent, specialized gaps where time and access matter most.
