ISO 9001 Certification

“We strive to exceed expectations on every project”

One of Delta’s Core Principles


Our highly motivated Delta team members recognize that a key element of exceeding our clients’ expectations is the delivery of exceptionally thorough and accurate studies, reports and construction documents.

To better facilitate our ability to do this, Delta developed a comprehensive quality management program that first received ISO 9001:2008 Certification from UL DQS, Inc. in 2009. We’ve maintained our certification through annual audits ever since.

As part of our program, we track several key metrics that we developed to allow each of our groups to measure our success with exceeding client expectations, such as our ability to meet promised delivery dates, our low change order percentage, and of course, the feedback we receive.

One of the cornerstones of our quality program is our commitment to soliciting, welcoming, and reacting to feedback from both our clients and our team members. Through this feedback, we learn, we adjust, then we improve.

We are exceptionally proud that Delta is one of the very few AEC firms whose quality program rises to the level of achieving and maintaining ISO Certification. However as we all know – based upon the constantly changing marketplace, technologies, available materials, and the economy, the delivery of high quality studies, reports and construction documents is not a destination but a journey. We’re now eight years into our journey, and we have recently transitioned our quality management program to conform to the requirements of ISO 9001:2015 – the newest ISO 9001 international standard – and we will be pursuing certification under this standard in February 2018.

Our current ISO 9001:2008 Certification is valid through May 2018.
