Arizona Reinforcing Bar and Wire Mesh Residential / Commercial Contractor (CR-70) Exam Book Package

The Arizona Reinforcing Bar and Wire Mesh Residential / Commercial Contractor (CR-70) Exam Book Package is designed for contractors, qualifying parties, reinforcing steel installers, post-tensioning personnel, concrete construction professionals, field supervisors, and business owners preparing for the Arizona CR-70 Reinforcing Bar and Wire Mesh contractor trade exam. This package brings together the key references used to study reinforcing bars, wire mesh, post-tensioning, concrete construction practices, building code requirements, residential code requirements, and OSHA construction safety.

The CR-70 classification is a dual residential and commercial reinforcing bar and wire mesh classification in Arizona. This means it is connected to the scopes of work permitted by the commercial and residential reinforcing bar and wire mesh classifications. Candidates preparing for this exam should understand the installation and repair of reinforcing bars, post-tensioning, and wire mesh in residential and commercial construction settings.

Reinforcing steel and wire mesh work requires accuracy, planning, and safe field practice. Contractors and installers must understand reinforcing materials, placement requirements, supports, spacing, laps, bends, ties, cover, layout, construction documents, concrete coordination, post-tensioning field procedures, and jobsite safety. The Arizona CR-70 exam reflects these responsibilities by testing both trade knowledge and reference-based understanding.

This book package supports preparation for the major exam categories, including post-tensioning, reinforcing steel materials, reinforcing steel placement, and safety. The included references help candidates build a stronger understanding of how reinforcement is installed, protected, supported, inspected, and coordinated with concrete construction. Candidates should also be prepared to use code references efficiently for open-book exam questions.

The Arizona CR-70 exam is an open-book test with specific rules about which references may be brought into the examination center. Candidates are responsible for bringing their own approved references. The remaining books in this package are important study materials that help build trade knowledge before exam day, even though they are not allowed in the testing room.

Exam Details

The Arizona CR-70 Reinforcing Bar and Wire Mesh Residential / Commercial Contractor trade exam contains 50 questions. Candidates must earn a minimum passing score of 70%, and the time allowed for the exam is 120 minutes.

The exam content outline includes the following subject areas:

• Post-Tensioning
• Reinforcing Steel - Materials
• Reinforcing Steel - Placement
• Safety

Post-tensioning questions may involve field procedures, tendon placement, anchorage concepts, stressing operations, safety, protection of tendons, slab preparation, inspection concerns, and coordination with concrete placement. Candidates should understand the basic purpose of post-tensioning and the field practices used to protect the system before, during, and after concrete placement.

Reinforcing steel materials questions may involve reinforcing bar types, sizes, grades, wire mesh, supports, ties, accessories, splices, bends, coatings, storage, handling, and protection. Candidates should be familiar with common reinforcing materials used in concrete construction and how those materials are identified and prepared for placement.

Reinforcing steel placement questions may involve layout, spacing, lap splices, cover, supports, chairs, dobies, bar mats, wire mesh placement, placement tolerances, drawings, field adjustments, concrete coordination, and inspection readiness. Proper placement is essential because reinforcement must be located correctly to perform as intended inside the concrete.

Safety questions may involve OSHA construction standards, personal protective equipment, material handling, fall protection concepts, reinforcing steel hazards, impalement protection, tools, lifting, access, concrete work, post-tensioning hazards, and safe jobsite practices. Since reinforcing steel work often involves sharp bar ends, heavy materials, elevated work, bending equipment, cutting tools, and coordination with concrete crews, safety preparation should be treated as a major part of exam study.

Open Book Test

The Arizona Reinforcing Bar and Wire Mesh Residential / Commercial Contractor (CR-70) Exam is an open-book test. Candidates are responsible for bringing their own approved references to the examination center. The testing center does not provide the reference materials.

The approved exam-room references include:

• Code of Federal Regulations - 29 CFR Part 1926 (OSHA), with latest available amendments, or Code of Federal Regulations - 29 CFR Part 1926 Selections by PSI
• International Building Code, 2018
• International Residential Code for One- and Two-Family Dwellings, 2018

The following references are listed for study but are not allowed in the examination center:

• Placing Reinforcing Bars
• Training and Certification of Field Personnel for Unbonded Post-Tensioning - Level 1 Field Fundamentals
• The Contractor's Guide to Quality Concrete Construction - 4th Edition

Candidates may use a silent, nonprinting, non-programmable calculator during the exam. Approved references may be highlighted, underlined, annotated, and indexed before the examination session. Candidates may not write, highlight, underline, or index references during the exam.

Additional papers are not allowed with approved references. This includes loose papers and attached papers. References may be tabbed or indexed with permanent tabs only. Permanent tabs are tabs that would tear the page if removed. Temporary tabs, including removable sticky notes or Post-It style tabs, are not allowed and must be removed before the exam begins.

Downloaded reference materials may be brought into the testing center only when properly bound. Spiral binding or hole-punching and placing the material in a binder are acceptable binding methods. Candidates should prepare all approved exam-room references before test day so the books meet testing-center rules.

Because only OSHA, the International Building Code, and the International Residential Code are allowed in the exam room, preparation should be divided into two parts. First, use the study-only books to build trade knowledge in reinforcing steel, wire mesh, post-tensioning, and concrete construction. Second, practice using OSHA, the IBC, and the IRC so approved references can be used efficiently during the open-book exam.

Licensing Steps

Arizona contractor licensing is handled by the Arizona Registrar of Contractors. A candidate pursuing the CR-70 Reinforcing Bar and Wire Mesh Residential / Commercial Contractor classification should review the current state licensing requirements and application instructions before applying.

The qualifying party for the license must complete the applicable examination requirements for the classification. Arizona contractor applicants may also need to complete the Arizona Statutes and Rules Exam, which covers state-specific contractor laws, rules, and regulatory responsibilities.

After the required examination process is completed, the applicant submits the contractor license application and supporting documents to the Arizona Registrar of Contractors. The application process may include business entity information, qualifying party information, experience documentation, bonding, financial responsibility, background-related forms, and other state-required documents.

Applicants should apply for the classification that matches the work they intend to perform. The CR-70 classification is a dual residential and commercial reinforcing bar and wire mesh classification. It is intended for contractors who need both residential and commercial authority for covered reinforcing bar, post-tensioning, and wire mesh work.

Passing the trade exam does not automatically issue a contractor license. The exam supports the trade competency portion of the process, but the license is issued only after the Arizona Registrar of Contractors approves the complete application for the applicable classification.

State Requirements

Arizona uses contractor license classifications to define the type of work a contractor may legally contract for and perform. The CR-70 Reinforcing Bar and Wire Mesh classification allows the scope of work permitted by the commercial C-70 Reinforcing Bar and Wire Mesh and the residential R-70 Reinforcing Bar and Wire Mesh classifications.

The CR-70 scope allows the licensee to install or repair reinforcing bars, post-tension, and wire mesh. This makes the classification relevant for contractors who work with reinforcing steel systems in concrete construction, including residential slabs, commercial slabs, foundations, walls, beams, columns, post-tensioned concrete systems, and related concrete reinforcement applications within the classification scope.

Contractors should stay within the scope of the license issued to them. Reinforcing steel and post-tensioning work can overlap with concrete, excavation, structural, welding, general contracting, and engineering-related activities. Contractors should understand the limits of the CR-70 classification before bidding or performing work and should use properly licensed subcontractors when work falls outside the classification scope.

Residential and commercial reinforcing projects may involve coordination with general contractors, concrete contractors, engineers, inspectors, testing agencies, post-tensioning suppliers, rebar fabricators, and other trades. Projects may also require shop drawings, placing drawings, inspections, cover requirements, lap requirements, material staging, concrete placement coordination, and jobsite safety planning.

The exam book package supports study for the trade exam, while the state licensing process is handled separately through the Arizona Registrar of Contractors. Applicants should follow the state process for application timing, examination requirements, bonding, entity documentation, and final license approval.

Test Information and Study Materials

Preparation for the Arizona CR-70 exam should begin with the exam content outline. The exam covers post-tensioning, reinforcing steel materials, reinforcing steel placement, and safety. These categories connect directly to the work performed by reinforcing bar and wire mesh contractors.

For post-tensioning, candidates should study unbonded tendon systems, placement procedures, anchors, stressing operations, safety precautions, concrete coordination, tendons, sheathing, protection, support, and field quality concerns. Post-tensioning questions may require candidates to understand both the purpose of the system and the field steps used to install and protect it.

For reinforcing steel materials, candidates should review reinforcing bar sizes, grades, identification, bending, cutting, fabrication, storage, handling, wire mesh, bar supports, chairs, ties, dobies, spacers, and other accessories. Reinforcing materials must be clean, properly supported, correctly positioned, and coordinated with the concrete placement process.

For reinforcing steel placement, candidates should study placing drawings, layout, spacing, clear cover, lap splices, hooks, bends, ties, supports, tolerances, construction joints, openings, embeds, slab reinforcement, wall reinforcement, foundation reinforcement, and inspection readiness. The location of reinforcing steel inside the concrete is critical because misplaced reinforcement may reduce performance and create inspection problems.

For wire mesh, candidates should understand handling, placement, lap requirements, support, elevation control, cutting, field adjustment, and coordination during concrete placement. Wire mesh should be positioned properly so it remains at the intended elevation instead of being displaced during placement and finishing.

For concrete coordination, candidates should use The Contractor’s Guide to Quality Concrete Construction to understand how reinforcement interacts with formwork, concrete placement, consolidation, finishing, curing, joints, tolerances, and quality control. Reinforcing steel contractors often work closely with concrete crews, so preparation should include the practical sequence of placing, inspecting, and pouring concrete.

For OSHA safety, candidates should become familiar with OSHA 29 CFR Part 1926. Reinforcing steel and post-tensioning work may involve sharp bar ends, lifting and carrying heavy materials, bending equipment, cutting equipment, elevated work, fall hazards, impalement hazards, concrete operations, and coordination with cranes, pumps, and other jobsite equipment. Candidates should practice locating OSHA topics quickly because safety questions may require reference lookup during the open-book exam.

Strong preparation includes organizing the approved references and using the study-only books to build trade knowledge. Highlight important sections in OSHA, the International Building Code, and the International Residential Code, add permanent tabs, and practice looking up information quickly. With 50 questions and 120 minutes, candidates should manage time carefully and avoid spending too long on any single question.
