What Do Our Clients Have To Say?
"I wanted to reach out and send a Quality High Five to recognize efforts from the on-site PNL Team this week. I had to stand down a couple of our new subcontractors this week. Andrew, Neil, and Bobby took the time to meet with me and my subcontractors in the field to educate and align on requirements/ inspection procedures. In addition, they walked with my new CSA QA/QC Engineer to identify various, specific issues to look for during his inspections prior to 3rd party review.
This project has presented innumerable challenges- but the consistent communication, positive attitudes, and wealth of knowledge shared has been, and will persist to be the fuel for fostering an excellent culture of quality at the project, Andrew & Neil’s support has not gone unnoticed, and is greatly appreciated by me & my team." - Calli Kube, Quality Control Manager, Hoffman Construction Company (3/10/2023)
