What RP Constructors does

RP Constructors, LLC is a privately held full-service design-build construction and engineering firm headquartered in North Sioux City, South Dakota. Founded in 2007 by Ryan P. Callaghan, the company operates across six integrated service divisions: Shoring & Ground Improvement, Site Heavy Civil, Environmental Water & Wastewater, Industrial Design & Build, Hydro Excavation & Sewer Cleaning, and Plumbing. Through its sister company, Civil Engineers & Constructors (CEC), RP delivers an integrated Engineering, Procurement, and Construction (EPC) model that bundles surveying, engineering design, and self-performing construction for municipal, industrial, and commercial clients across 10 Midwestern states.

The company's technical differentiation rests on self-performing capabilities and specialized equipment, including excavator-mounted MKT hydraulic hammers for tight-access pile driving, PACP-rated CCTV pipeline inspection technology, hydro excavation combination jet/vac trucks, and bypass pumping systems for sewer rehabilitation. RP holds Certified Environmentally Responsible Contractor (CERC) status from Environmental Risk Professionals. Its engineering practice includes licensed Professional Engineers performing in-house Global Stability Factor calculations for deep excavations and licensed PE project managers overseeing industrial and consulting engagements.

RP Constructors generates revenue through project-based contracts secured via competitive bidding (including a $12 million industrial wastewater pretreatment facility for Prestage Foods of Iowa in 2017 and a $6.6 million City of Sioux City Myrtle Street reconstruction in 2020) and relationship-based subcontractor engagements with general contractors such as W.A. Klinger. Pricing is quote-based and scope-dependent. The company employs over 85 people across trades and specialties, operates from offices in North Sioux City and Tea, South Dakota (the latter opened in 2025), and distributes its services through direct sales engagement, competitive procurement, and subcontractor partnerships.

Broad incumbents

• Ames Construction: Heavy civil and industrial general contractor operating across the Midwest and Mountain states. Comparable for site heavy civil, underground utilities, and industrial site work that overlaps with RP's Site Heavy Civil and Environmental Water divisions.
• Black & Veatch: Global engineering, procurement, and construction firm with leading water/wastewater treatment expertise. Direct overlap with RP's environmental water/wastewater vertical through design-build water/wastewater treatment plant construction.
• Mortenson Construction: National design-build general contractor with strong industrial, civil, and renewable energy practices. Comparable as integrated design-builder competing for similar industrial EPC and infrastructure work in the Midwest.
• McCarthy Building Companies: Larger national employee-owned design-build GC operating across industrial, water/wastewater, and infrastructure verticals. Competes with RP for larger municipal and industrial design-build work but serves a broader portfolio of healthcare, education, and commercial projects.
• Burns & McDonnell: National employee-owned engineering, architecture, and construction firm with strong water/wastewater and industrial design-build practices. Comparable as a one-stop integrated EPC competitor in many of RP's primary municipal and industrial verticals.

Direct peers

• Miron Construction: Midwest-headquartered, family-owned design-build general contractor offering industrial, civil, and infrastructure construction services. Directly comparable in regional footprint (Wisconsin/Midwest origin, multi-state presence), integrated self-perform model, and similar target verticals (municipal water/wastewater, industrial design-build).
