Quality control starts with well trained personnel, and a stringent network of engineering support.

At DBA we understand that quality control observation involves more than identifying construction problems. We provide innovative and cost effective solutions. Our team of responsive well trained field technicians has the ability to accurately identify construction problems and provide timely cost effective and practical solutions. Our engineering support staff works closely with the field staff to determine the most effective solution to specific construction problems.

We have established our own in-house laboratory for quality construction materials testing. Soils, Aggregate, Concrete, Masonry, and Fireproofing are tested by our certified lab technicians who perform ASTM standard and ACI standard testing and produce accurate test reports. To ensure continued high quality testing results our laboratory is enrolled in the Cement and Concrete Reference Laboratory’s inspection program and participates in the biannual laboratory proficiency program.
