Our Clients Reviews

I want to thank you & your team for the excellent support & results for two recent projects I managed; Primary Blow Heat Condenser installation and the E-4 Evaporator by-pass installation.  Specifically, the pre-planning, execution and on-going communication throughout the project execution was superb.  I was always kept informed and when changes arose the team was quick to propose alternatives to keep things moving forward.  This allowed me to make effective project decisions on cost & schedule as well as allowing me to better coordinate other resources.  Most of my communication was with Don & Ron and of course, they were great.  Even the individual boilermakers were excellent at presenting situations and handling themselves in a professional manner.  Kudos to all of them.  You should be proud of the way your business was represented by the entire onsite team. It’s easy to downplay this as just ‘doing what you are paid to do’ but I think your team went beyond that.  They make it easy to do business with C H Murphy || Clark-Ullman.  Thanks again!

I Would like to thank you for all your Professional Hard Work you did on our turnaround. As we manage the turnaround, it is your Project Management which makes it successful. Your Team stepped in to do the important project we have to do on our shutdown. I know all the Engineers and Project Owners are very pleased for you to handle the management of the Projects. You all worked safely & productively while producing the work with the highest quality. Your team also stepped in on several occasions to help our maintenance team along with Items I asked for help with to make sure they were done on schedule during the turnaround correctly. Your company and personnel are always very professional and their work top quality. We meet daily discussing items which contractors, operations and maintenance were involved with and your input was extremely valuable. Thank you so very much. We are looking forward to a long relationship with CH Murphy || Clark-Ullman.

Just wanted to send out a note to say thanks. As usual all of your crew members were very professional, highly skilled, courteous, communicated and worked well with others. They met or exceeded all of our safety expectations, were attentive during the permitting process, and brought up things during the permitting process that we might have missed due to their higher knowledge of the welding process than ours. We had various times that we had to juggle projects a little due to other work being done in the same general area and your guys were accommodating to these changes and helped us to figure out things they could do in other areas to keep them busy. We did many different types of work requiring higher levels of permitting from confined space entry, high energy hot work, elevated work, life critical guarding among others, and your crews followed our requirements and expectations very well. They were good to point out things that came up during the day that needed addressed. They picked up of few other small jobs that came up and got everything done without us having to push back our startup. Jared and Duke were the ones that ran the crews and as always, they did a great job. Setting up the work to be done during their shift, monitoring the work to make sure it was done correctly and at a high level of quality, going over the permits, making sure all of their crews members were signed on to and off of the appropriate paper work. Working with their project leaders to go over the upcoming work so we could get it set up for them ahead of time. Just an all-out great job on everybody’s part. Your guys always come in here and do a fantastic job and are fun and easy to work with. Over the years we have also created a close friendship with many of them that will last a lifetime, you should be proud of all of them. It’s always a pleasure working with you and your crew members.
