At J-AAR, we take pride in fostering continuous learning and industry collaboration. That’s why we recently hosted the American Concrete Institute (ACI) Grade 1 Certification, bringing together professionals from across the construction sector to enhance their skills, stay up to date with industry standards, and ensure the highest level of quality in concrete construction. A Hands-On Learning Experience The ACI Grade 1 Certification provided participants with the opportunity to undergo practical training and certification exams for concrete field testing. This event is crucial for ensuring that industry professionals are well-versed in proper testing procedures, which play a vital role in maintaining the integrity and durability of concrete structures. Under the guidance of certified ACI examiners and experienced J-AAR Structural Group team members, attendees were able to perform essential tests, including slump tests, air content tests, unit weight measurements, and cylinder preparation for compressive strength testing. These hands-on experiences help reinforce best practices and ensure compliance with industry standards. Strengthening Industry Standards ACI certifications are widely recognized in the construction industry as a benchmark for excellence in concrete testing. By hosting this event, J-AAR Structural Group and Dutch Brothers Ready Mix contributed to the ongoing professional development of industry personnel, reinforcing the importance of quality control and precision in every project. We understand that accurate concrete testing is the foundation of safe and long-lasting structures. Events like these provide an opportunity for contractors, engineers, and technicians to validate their expertise and build confidence in their testing abilities. Commitment to Excellence At J-AAR, we are committed to advancing construction standards and supporting professional development within our industry. Hosting ACI Grade 1 Certification aligns with our mission to promote education, ensure best practices, and elevate the quality of work across all our projects. We extend our thanks to all participants, examiners, and organizers who made this event a success.
