Integrated Industrial Construction for Reliable, Fast-Track Project Delivery

IAC delivers complete industrial construction services with precision, efficiency, and accountability. Through our wholly owned subsidiary, Adelphi Construction LC, we self-perform civil, structural, mechanical, and electrical work to ensure seamless project execution and full quality control. Every build reflects IAC’s commitment to safety and disciplined project management, giving customers a single, dependable partner from foundation to startup.

Our construction teams bring decades of experience supporting industrial plants across the United States and abroad. By combining engineering expertise, OEM equipment integration, and field-proven safety programs, we help customers complete capital projects and expansions on schedule and built for long-term performance.

Integrated Engineering for EPC and OEM Systems

IAC’s engineering team supports every stage of project delivery, combining technical expertise with the efficiency of a vertically integrated organization. Our engineers collaborate across structural, civil, mechanical, electrical, and controls disciplines to design complete systems that perform reliably and install seamlessly.

Each design is developed with fabrication and construction in mind, allowing IAC to maintain quality control from the first drawing to final installation. This integration minimizes handoffs, accelerates schedules, and ensures that complex industrial systems are built exactly as intended.

Civil, Structural, and Mechanical Construction

Adelphi’s field teams deliver every project with precision and accountability, starting from the ground up. Our crews self-perform foundations, concrete, and structural steel erection to maintain schedule control and consistent quality. Mechanical capabilities include equipment setting, ductwork installation, and process piping to support complex industrial systems.

Because IAC manages engineering, fabrication, and construction in-house, each phase of work is coordinated for accuracy and efficiency. This integration reduces rework, improves safety, and ensures that every component aligns with design intent. From greenfield plants to facility expansions, IAC delivers dependable results backed by decades of industrial experience.

Electrical and Controls Installation

Adelphi Construction teams install and commission complete power and control systems that keep industrial operations running safely and efficiently. Capabilities include motor control centers, programmable logic controllers, instrumentation, and full plant automation for both new facilities and system upgrades.

By coordinating electrical and controls work with IAC’s in-house engineering and OEM equipment design, projects are completed with shorter commissioning times, seamless system integration, and long-term reliability.

Safety and Workforce Excellence

Safety is the foundation of every Adelphi Construction project. From pre-construction planning through field execution, every activity is guided by programs that protect people, equipment, and the environment. Dedicated safety personnel oversee site-specific training, inspections, and continuous improvement initiatives to ensure consistent performance across all job sites.

Adelphi Construction teams meet or exceed OSHA and MSHA safety standards and maintain certifications across multiple trades. This commitment to compliance and training supports safe, efficient operations even in the most demanding industrial environments. Skilled millwrights, welders, electricians, and construction managers bring the technical depth and accountability that define IAC’s culture of precision and performance.

Fast-Track Construction and Project Management

IAC and Adelphi Construction deliver projects on accelerated schedules without compromising quality or safety. Our integrated engineering, fabrication, and construction model allows decisions to move quickly from design to execution, minimizing downtime and maintaining schedule certainty. This fast-track capability has been proven across hundreds of industrial installations, from greenfield facilities to major plant expansions.
