Texas-sized Concrete Pour

I’ve worked on several concrete pours over the years (mostly less than 500 cubic yards in one placement), and I’ve seen just how sideways they can get in short amount of time.

For a new office tower in Houston, TX, CEMEX USA did a 13,799 cubic yard pour in 20 hours. I can hardly imagine the resources expended to plan and execute a pour of this size in such a short amount of time. - Jason Savage, DTC Civil Construction Instructor

CHANGE IS COMING - Allowable Items: CBT Exam versus Pencil-and-Paper Exam


The Mechanical PE Exams will convert to the year-round Computer-Based Testing (CBT) format starting in April of 2020. The October 2019 Exam is the last chance to take the Mechanical exams in the Pencil-and-Paper format. In this post, I want to take a closer look at the difference in what you’re allowed to take into the CBT PE Exam (which is virtually nothing) and what you can take into a Pencil-and-Paper PE Exam (which is almost anything useful within reason). 

The downloadable NCEES Examinee Guide contains information for the both the CBT and Pencil-and-Paper exams, including a list of what items you are allowed to have during the exam.

For the CBT exam, this list of allowed items is very limited.  The following items are allowed: official ID, one approved calculator without cover (spare must be in locker), a key to the locker, booklet and marker supplied by Pearson VUE, eyeglasses without the case, light sweater or jacket, and approved medications. You will be given a pad and a special pen to do all your calculations, which will stay in the exam facility when you have completed the exam. You may ask for additional pads or pens during the exam. That is it. Then there is the long list of items not allowed. Cell phones and computers, of course, fitness trackers, pagers, watches, wallets, purses, hats and other head coverings (unless religious in nature), bags, coats, books, notes, pens, pencils, erasers, food, and beverages. Please note that books and notes are included in the list of banned items. That means no references whatsoever. Your only reference during the exam is limited to the provided NCEES Reference Handbook PDF shown on your computer screen.

As for the current Pencil-and-Paper format, yes, you need an official ID, and you are not allowed any electronic devices including cell phones, computers, fitness trackers, or smart watches (wristwatches are okay). However, you will have your personalized reference materials and approved calculator (and spare if you like), and you can bring in two straightedges (such as a ruler, scale, triangle, or protractor) and handheld magnifying glass. You can even have snacks (hard candies, candy bars, and even gum which is restricted in the CBT facility) and nonalcoholic beverages. You can essentially set up a home away from home for the duration of the exam. I remember having a bag with morning goodies to eat and drink and then a separate bag for the afternoon. I know the chocolate yogurt flavored raisins I consumed during the afternoon portion of the exam were a key to my success. Not a chance having those in a Pearson VUE testing center, except during your timed 50-minute lunch break.

If you like “rules”, then you are going to love the new CBT format. If not, then if you don’t take and pass the October 2019 PE Exam, you will have no choice but to comply with a great many rules.  - Dr. Tom

Engineer Astronaut - Truly Extraordinary

At DTC, one of our big messages is about Achieving the Extraordinary. I was so inspired to read about astronaut Christina Hammock Koch, who blasted into space on March 14. She is an alumna of NC State and the North Carolina School of Science and Mathematics, both institutions that I’m proud to have attended as well. As a kid, I dreamed of one day being an astronaut, and although my career has led me down a more terrestrial path, I still find a space launch exciting. Koch and her colleague Anne McClain will be making an historic spacewalk on March 29, as the first all-female crew to do so. An engineer by training, she will do something so few of us will ever experience, but we will all benefit from the knowledge gained, as we try to achieve the extraordinary in our own ways! - Beth Sciaudone, DTC Civil Water Resources & Environmental Instructor

FEATURED TESTIMONIAL - The Only Reason I Passed

“The only reason I passed the Mechanical TFS PE exam was because of Dr. Toms Classroom. I struggled through college, barely passing despite giving it everything I had. This was a huge confidence boost. I just wanted to write and say thank you.”

Where the Sun Always Shines

Of all the alternatives to generating electrical power over fossil fuel or nuclear technology, solar power is probably the one that has the most promise. The biggest challenge to it becoming our sole source of power is that the sun only shines part of the day, and then many days are too cloudy to allow the necessary light to contact solar panels.

One way to get around this challenge is to place solar panels where the sun always shines and there are no clouds - in space.  In synchronous orbit  around earth, they can collect energy and with the appropriate microwave technology, and beam that energy to earth 24/7/365, as they say.

Turns out this idea is not new, but technology and cost have be kept it from becoming a reality. However, China has just announced that it plans to put a solar power station in orbit by 2050. That is also when it is predicted that there will be 9 billion people on earth who will need every watt of electricity that can be produced.  No details of their solar power station have been forthcoming from the Chinese, however a team of researchers at Cal Tech are keeping a close eye on developments, and are working on various strategies for space-based solar power stations.

Ali Hajimiri, professor of electrical engineering at Cal Tech, says that with a continuous source of light from the sun, not subject to the earth's atmosphere, such power stations could have eight to nine times the solar energy available.  This could mean a solar power station in space producing 2,000 gigawatts whereas the most efficient earth based solar power station currently produces less than 2 gigawatts, a 1,000 to 1 difference.  That has certainly gotten the attention of the Chinese, and it certainly has gotten my attention. - Dr. Tom

“If you don’t read my entire testimonial – here is the 'bottom line upfront:' Look no further! Like many other folks, I had previously taken the Mechanical PE exam without a great deal of structure.  In fact, after two unsuccessful attempts in the mid 1990’s – I placed professional registration on hold – uncertain if I would ever try again. However, with life and work ever-changing, it became clear that professional registration would be a benefit. Needless to say – I passed the Mechanical Thermal/Fluids exam and a great deal of credit goes to Dr. Tom and the course.  If you work the program, watch the lectures, do the problems, prepare the personalized resource notebooks, and use the participant forum…you will pass the exam. This structure, organization, and commitment are why this program is so successful and I will be recommending this to my colleagues. Thank you Dr. Tom and your entire staff.”

CHANGE IS COMING - The CBT Exam Experience Versus the Pencil-and-Paper Exam Experience



The Mechanical PE Exams will convert to the year-round Computer-Based Testing (CBT) format starting in April of 2020. The October 2019 Exam is the last chance to take the Mechanical exams in the Pencil-and-Paper format. In this post, I want to look at the difference in the experience of taking a CBT PE Exam and taking a Pencil-and-Paper PE Exam.

Understanding the difference is an important consideration, because, for many people what keeps them from passing is the nervousness generated by the exam experience itself and not their lack of understanding or ability to solve problems. 

One key change in the exam experience is that the CBT format uses what is called Linear On The Fly (LOTF) testing, meaning that each examinee will get a different exam. Currently, when the NCEES administers the Pencil-and-Paper PE Exams, everyone in the country takes the exact same exam in their discipline. Yes, the questions for one exam cycle will be different from another, but everyone is facing the same changes each time. However, with the CBT exam, you might get a lot of questions in an area you are not very familiar with and the person beside you, or one who comes in another day, gets just the right number of questions in the areas they are familiar and very few in their weak areas. This sets up a much bigger “roll of the dice” factor, and I have a “minimum of high regard” for that philosophy of testing. It will, however, be the case for the CBT format.

If that doesn’t make you nervous enough, then watch the NCEES YouTube video showing what will happen when you arrive at a Pearson VUE Testing Center to take your exam. The sight of someone having to pull out all the pockets of their pants and do a 360º turn in front of the administrative assistant is a bit disconcerting. The assistant is smiling, but the adversarial nature of the things you are required to do is unnerving, to say the least. First, you read the rules, show an approved ID, provide a digital signature, have your picture taken, and then provide a palm vein scan. You are told to put everything but the few allowable items into a locker. Next, another ID check and palm vein scan, and you are given your work pad and pen and escorted to the testing room door where you are to read, yet again, the rules. You are then escorted into the small testing room and the cubicle where you will spend the next eight hours taking the exam, carefully watched by a proctor over security cameras. At your cubicle, you watch a short tutorial on how to proceed with the CBT exam, then the clock starts and will literally count down the seconds until your time is over. You can take breaks (palm vein scan going out and coming back), and you are intensely watched so that if you access your locker you don’t violate one of the rules. There are numerous security procedures that you must follow precisely or your exam will be invalidated. You can learn more about the new CBT experience from a series of NCEES videos.

In contrast, for a Pencil-and-Paper exam, you arrive along with hundreds of other people and are shown to a large table in a very large open auditorium where you can begin to set up all the references you have brought. Yes, no cell phones or computers, but you can have just about anything else including food and drink, though at some locations these are restricted. In the CBT cubicle, you can’t even chew gum. In the pencil and paper environment, there is an air of excitement and expectation, that you are part of a bigger world. Yes, you are sitting in a pre-assigned seat and someone asks for your ID, but that is it. You sit waiting for the exam to begin among a great many others with the same ambition of becoming a PE. Instructions are read to you by a person at the front of the room, usually at a podium. A team of proctors circulate, helping people get settled. Professional, but very friendly. During the exam, if you have to use the restroom, you simply raise your hand. Once the Pencil-and-Paper exam starts, there is a big clock on the wall and periodically the time remaining will be announced. Again, none of the intimidation generated by the CBT format.

Those are my impressions of the two vastly different exam experiences, and the Pencil-and-Paper exam wins hands down in my book. I can tell you that without a doubt I would not be looking forward to taking the exam under CBT format conditions. I would like to think that it would not affect the outcome, however, I am sure my stress level would be maxed out during the entire experience. If the CBT experience does not appeal to you, then your only option is to take the Pencil-and-Paper PE exam now and pass! After the October 2019 Exam, the CBT format will be your only option. - Dr. Tom

FEATURED TESTIMONIAL - The Binders Proved To Be a Lifesaver!

“I successfully passed the PE exam on my second attempt. I went in much more confident and I can thank your class for that. The binders that we made from the class proved to be a lifesaver and I was able to answer most of the questions simply from them alone. This saved a ton of time as I wasn't constantly flipping through the MERM and the other mountains of books desperately looking for an answer or random equation.

I feel like the biggest advantage that your class brings to the table is that you structure all of the information you need in a way that is much easier to find. I feel that any competent engineer should be able to answer just about every question the PE throws at them if given enough time, but the exam forces you to be fast and efficient. Even if you are the most well-versed engineer in the world if you don't have a method in place to quickly find the equation or topic that you are looking for it can make for a really tough test day.

I will definitely recommend your class to peers who are considering taking the PE in the future. Thanks for everything!”


- Brandon F., PE, Dallas, TX

From Dr. Tom - "Mechanical Engineers, what this DTC participant is saying reinforces my recommendation to take the October PE Exam while you can still use these binders that you create yourself. This is your last chance!"

Stainless Steel = 100-Year Bridge

The Bonner Bridge on NC 12 over the Oregon Inlet opened for traffic on February 25, 2019. This bridge was the first bridge in North Carolina constructed with stainless steel reinforcing, and is intended to have a 100 year service life. Increased service life of critical public infrastructure is becoming more common and this project is an excellent example. It’s constructed with numerous precast concrete elements, which not only simplified construction, but also can be more durable than cast in place concrete. The precast elements on the bridge are prestressed, which allows for better crack control in the concrete, which is critical to preserving the integrity of the reinforcing steel in a saltwater environment like the Oregon Inlet.

If you’d like to see the construction process in action, check out the excellent series of videos produced by Dare County that tracks the building of the bridge from the very beginning in March 2016 to its opening nearly three years later. - Mike Batten, DTC Civil Geotechnical Instructor
