The President's Series - Mark Ventrelli

Jul 2015

Scott Brown, Director of Business Development for the W-T Family of Companies, dives into the professional experience and lives of our company presidents. Next up: Mark Ventrelli, Vice President of W-T Mechanical/Electrical.


When did you first start at W-T Engineering, and what were your responsibilities at the time?

I became employed at W-T Engineering in February of 2002. At that time, my responsibilities were similar to my current tasks that I perform, including mechanical design, load calculations, and CAD layout specifications.

When did you know that you wanted to become an engineer?

I was attending Northern Illinois University, as an undecided major. While I was taking math and science classes, I met some friends that were entering the engineering program. Since I was undecided at the time, I figured I would try engineering, which has worked out pretty well.

What would you say to a young person, who is interested in entering the construction design field?

Experience in the field is essential. It is important to see how things are installed, because ultimately that is where it all ends up. Ideas that makes sense on paper, might not make sense in the field. Making time to go check out job sites, is an essential part of understanding how they actually are built.

One of my former colleagues used to say, “Measure with a laser, mark it with a crayon, and cut it with a chainsaw.” Meaning this is not a hard scientific field, we are not designing to the 10th decimal point.

What changes have you seen in the industry since you first started?

Since I first started in the industry, the biggest change has been AutoCAD. Everything used to be much slower. It went from sending letters, to fax machines, and now to email. Now everything is much more efficient.

What do you like to do in your free time?

I play the drums in a couple of bands. We mostly play Rock n’ Roll music around the Northern suburbs at local bars. One of the bands that I play in is called “Mid Life Crisis.”

As the built environment becomes more stringent with energy codes, what steps do owners of new and existing facilities need to take to ensure they are compliant?

The first step is to hire a well-trained engineer that knows the energy codes. Do not always look at the first cost. By putting in more efficient equipment, you can actually save money in the long run.

If it is an old building that needs a new furnace, it is in the best interest to put in a new, more energy efficient piece of equipment. Renovations of a large building with a 50 year old boiler can be kept in place; however, if there are any upgrades in the system that need to be made, those should be done.
