AZ ROC A (KA) Dual Engineering case studies
AZ ROC A (KA) Dual Engineering · Put your knowledge to work in context.
The Arizona Registrar of Contractors A (KA) Dual Engineering license is a state contractor credential for firms that take on engineered commercial and industrial construction - the kind of work where a single project mixes structural concrete, steel erection, mechanical equipment, electrical distribution, and process piping. The "Dual Engineering" designation signals that the qualifier is examined across both general engineering and the building-trades engineering scope rather than a single narrow trade. Candidates are typically experienced superintendents, project managers, or owners who already run this work and now need to qualify a licensed entity. The exam is multiple choice and blends business and law - contracts, lien rights, licensing rules, employment and safety obligations - with technical material spanning sitework and excavation, concrete and structural systems, mechanical and electrical installations, plumbing and piping, structural steel and welding, plan and specification reading with estimating, and code and environmental compliance. The AZ ROC A (KA) Dual Engineering case studies are 5 cases and about 2,786 words.
