Customer Testimonials

EPIC did a great job on our modular pipe rack project. EPIC’s project manager was very detail-oriented and provided impressive technical capabilities. There were many areas where EPIC’s project manager was able to add value based upon his experience working on similar modular construction projects. With EPIC’s open communication, we were able to quickly overcome any obstacle that arose during the project. Their industry knowledge and experience helped ensure the project was completed in a quality fashion while achieving the project schedule. I look forward to another opportunity to work with EPIC!

I have had the pleasure to work with EPIC on numerous successful jobs, and I’ve been impressed with their team of process engineers and skilled craftsmen. They are adept at achieving specified separations through column sizing and process modeling. Quality and customer service are clearly priorities for EPIC, and I recommend them for any distillation project

Mead O’Brien is a customer of EPIC Systems for both engineering and skid-mounted fabricated safety systems. Our experience with them over the past several years with recurring projects has been exemplary. The level of detail and professionalism for which they execute their business on our projects, starting with our assigned Project Manager, gives us high confidence regarding all evolution of our project including specification details, code compliance, welding procedures, and a host of other details necessary for refinery installation are all taken into account by their engineers, technicians, and other employees who touch some phase of our orders.

I have personally known the CEO for a number of years and have become familiar with his teamwork approach to business leadership and success. I also know several EPIC engineers and their professional track record from their time previously working for Fortune 500 companies. The proven experience and track record of the company technical employees, not just in years, but in breadth and depth is impressive.

Our company has a high trust and confidence level in Epic Systems when we engage them with our business.

As a plant we have relied on EPIC Systems to be our main resource for process design and to be a project manager on some of the bigger projects. We like using EPIC since they are very cost effective for the value you get. When we have dealt with some of the larger Engineering firms, they tend to involve too many disciplines that are not necessarily required.” With EPIC, we get the Engineer who can handle the job, and we deal directly with him (her).

We have always had more than qualified Engineers from EPIC that could handle the work. And over the years we have developed close working relationships with several of their people. I don’t think you can go wrong with choosing EPIC.

EPIC Systems takes a conservative approach to safety, touching all safety bases such as earthquake and fire control. Careful and thorough implementation of the projects from all disciplines, including document control and cost control, made the projects move surely and safely.

Our collaborative partnership with EPIC enabled us to deliver a strategically-important project on budget and within a very aggressive timeline. Installation and start-up were completed in a matter of weeks and products made in the EPIC-supplied equipment fully met expectations upon the first production.
