I coordinated closely with the contractors to ensure every component met our specifications and industry standards.

One specific instance that stands out is when we discovered a discrepancy in the specifications of the ductwork being installed. I immediately halted the installation and conducted a thorough review, working with the supplier to resolve the issue and ensure all subsequent shipments met our criteria. This proactive approach not only kept the project on schedule but also maintained the high-quality standards we were committed to. It reinforced for me the importance of meticulous QA/QC processes in delivering reliable and efficient engineering solutions.”
