Engineering Writing Style Guide – 6 Things to Know

Great technical writing conveys clear and accurate information. Using my engineering writing style guide, you’ll know what good technical writing is.

Important to realize, you don’t need to be the next Stephen King. But, to write like a great engineer, you need to have a certain level of writing skills. This applies to all types of engineering.

Technical writing helps others understand and implement complex ideas. So, bad writing can lead to costly mistakes and even worse, deaths.

That’s why engineers with poor writing skills are not reliable in writing-related tasks. Bad wording of a sentence or two is enough to cause design failure.

As an engineer, doing technical writing is very common. You write such things as:

  • Reports
  • Design documents
  • Calculation summaries
  • Manuals

I read a lot of technical writing myself. It’s frustrating when I come across poorly written material. It shows the writer doesn’t care about their craft.

And I know, technical writing isn’t easy. But it’s a great skill every engineer should have.

It allows you to help people understand a subject you’re an expert in. For example in your career, you may write for:

  • Other engineers
  • Managers
  • Consumers
  • Technicians
  • Contractors

To that end, in my engineering writing style guide, I’ll go over 6 important writing pillars. Every great technical writer needs to consider these pillars.

Pillar #1: Being clear and concise

Your readers probably don’t know all the engineering terms you use.

Don’t expect them to know either. So, use a lot of details in your writing.

When you’re describing something, don’t leave out details. You don’t want someone to assume something incorrectly. You want your writing to be as clear as possible.

As an example, below is a note I wrote for a contractor for their implementation of my design. The note holds their hand for the entire part of the work.

As a summary, I wanted the contractor to route a new conduit. The conduit routes from a new service electrical panel to an existing one.

As a result, the existing panel will have a lot of obsolete parts left inside. Because all the utility servicing parts are now in my new panel.

“Route conduit from 250A-3p breaker inside of new Pump Station #1 MCC to Meter/Main Switchboard #1 at Mont Building. After coordination with utility and District, penetrate Meter/Main Switchboard #1 breaker cabinet from the side using an LB condulet.

Land wires as shown on the line side of the existing 600A-3p breaker. Terminate ground from Pump Station #1 to Meter/Main Switchboard #1 ground bus.

Disconnect and remove all equipment from inside of the Meter/Main Switchboard #1 as shown, after coordination with the utility and the District.

Then use appropriate seal box covers for all exposed box openings.

Interconnect time to be limited to 24 hours. Coordinate with the utility and the District to establish the cutover schedule.

After the cutover, the contractor to coordinate with the utility and demolish the existing service.

For greater detail on Meter/Main Switchboard #1, see drawing set dated January 2000, prepared by engineering firm X.”

Keep in mind, this note went with a series of drawings I had made too. Everything together helps perfectly illustrate what I want the contractor to do.

All in all, I’m very detailed in my writing. I want to limit as much confusion and mistakes as possible.

But, an English professor wouldn’t consider the writing to be proper. And, that’s okay.

The goal of a technical writer

Your goal is to make a reader who doesn’t know something to understand. In other words, make a complex problem sound easy in any way possible

Also, it’s great to have empathy as a writer.

What do I mean? A designer will not always have empathy for someone who first views their design. They may think everyone should just “get it” since they themselves get it.

But a great technical writer has empathy. They place themselves in the shoes of an uninformed reader.

As a result, they always produce great content. This way, every reader will have a great experience understanding a given idea.

Important Note: to write clearly you need to understand the subject you’re writing on. Without understanding the subject, you can’t write anything useful. 

This further highlights the importance of each sentence in your writing. You don’t want to have ambiguity in any sentence you write. 

Pillar #2: Keeping it simple

Engineering includes many difficult concepts. Some of the ideas can even make an engineer’s head spin.

Without question, making a difficult subject easy to read is a skill. Yes, technical writing will include some technical words. That’s because we’re dealing with engineering.

Overall though, your writing should be easy enough for an 8th grader to read.

Also, you want to keep your writing barebones simple. This includes leaving out your personality. No one cares about your personal writing style.

As well, writing using a top-down approach. In other words, you start from the basic conceptual ideas. Then you drill into the more specific ideas further into your writing.

For example, when you read a manual, the basic information you’ll find presented first. Then as you read more you’ll find more technical information stuffed in.

In short, great technical writers explain complex ideas in simple words.

Pillar #3: Keeping it short

This sounds contradictory to Pillar #1. How can you keep it short yet add a lot of details?

The trick is to add all the details you think are necessary. But not more.

What I mean is, certain things don’t need an explanation. As an engineer, you need to know what needs explaining and what doesn’t.

Let’s go back to my contractor’s note in Pillar #1 as an example.

If you noticed, I assumed the contractor has some level of knowledge. It’s not a far stretch, given contractors need to earn a license to practice.

Thus, in my note I didn’t explain things like:

  • What a conduit is
  • What tools to use to penetrate the existing panel
  • How to demolish the existing panel
  • The safety measures the contractor needs to follow

As I mentioned, the engineer needs to make the judgment call on what to include. You need to know your reader audience.

If I wasn’t directing my writing to a contractor, I’d include more details. But, since I’m writing to a contractor, I keep it short.

In short, the intent is not to write a novel. The goal is to communicate your point concisely yet clearly.

Pillar #4: Getting rid of fluff talk

Fluff talk is sometimes good. For example, if you’re speaking with business folks, you want to add fluff talk to your writing. Pad your words as they say.

But with pure technical writing, you want to jump right into your point. Just dish it out.

Be very specific. This makes your word choice very important. Use words that are to the point and don’t cause confusion.

As readers only want to absorb the following things:

  • How does it work?
  • What are the problems?
  • How do we improve it?
  • How does it fix my problem?

When I read about how something operates, I don’t care about “getting to know you” conversation. Just tell me how it works. That’s it.

Funny thing is, this way of writing is a great way to build professional relationships. If you can dish great information to me efficiently, we’ll build an instant bond. Because I know you get it.

Think of it like the instructions you find in the furniture you buy at IKEA. You’ll find clearly written steps. The instructions are straight to the point.

So yes, technical writing is dry. This is probably why you hear things like:

  • Why is engineering writing so boring to read?
  • How come engineers’ writing is only aimed at other engineers?
  • Why can’t engineers write using any persuasion?

There’s some truth to these questions. But again, technical writing isn’t meant to entertain you. If you want entertainment, go pick up a novel.

Technical writing serves a different purpose. Plus, any great engineer is flexible with their writing. This leads us to my next pillar.

Pillar #5: Writing to your audience

Know your audience!

Depending on who you write to, your writing style will differ. Your content will differ too.

If you’re writing to other engineers, your writing needs to be straight to the point as I discussed.

But, if you’re writing to business people, you’ll need to use a different writing style. You’ll need to blend technical writing with formal writing.

Like in this blog, my writing style here differs a lot from how I write in my engineering work. Here I try to make my writing scannable. I limit the use of big technical words.

In short, I want my writing to be fun to read. This is why you’ll find a lot of fragment sentences here. I find a looser writing style works better for casual readers online.

Now for a college paper, my writing style would be even more different. My writing would be much more proper.

With technical writing though, you need to forget what you learned in school. I’m talking about what schools classify as “good writing”. Because technical writing is:

  • Very specific
  • Boring
  • Easy to understand

As a result, some sentences may not be correct. But the end goal is to communicate your point efficiently. If that means swerving from what someone views as wrong, then so be it.

All in all, you need to adapt your writing style to your readers. I often find myself writing to people who could care less about technical details.

So, I need to dumb myself down without getting too technical. But also, make sure I don’t lose the important technical points I’m trying to get across.

Pillar #6: Using good grammar

In the grand scheme, perfect grammar is not super important. Especially if you’re able to get your points across efficiently.

Of course, you still need to know basic grammar. Like how to use a comma properly. That’s a given.

That said, if your grammar is great, it’s a huge plus. So, why not improve your grammar? It can only help.

Here’s an example of poor grammar gone wrong:

Poor grammar: The contractor shall have drilling people and foundation skills.

Good grammar: The contractor shall have drilling, people, and foundation skills.

Do you see how the meaning of the entire sentence changed because of a few commas? I know it’s a crazy example, but you get the point.

Small grammar mistakes can lead to incorrect implementation of a design. I’ve seen it.

This further drives my point home. Technical writing will suffer from poor grammar.

“How to write like an engineer?” wrap up

Writing like a great engineer isn’t easy. In fact, you can be the greatest engineer on the planet. But if no one understands you, then you’ll quickly lose a lot of your effectiveness.

So, you need to be able to mix technical concepts with good writing skills.

School taught us to write a certain way. With engineering writing, you need to shuffle what you’ve learned.

In other words, strip away a lot of the fluff writing. Then kick out the formalities and scale up the details. All the while, keep your writing simple and readable.

That’s my engineering writing style guide in a nutshell.

Even more, by adopting this way of writing you’ll become a better engineer too. It’ll help you think through your designs and spot mistakes.

After doing technical writing, I always gain a deeper understanding of a subject. This includes a better theoretical understanding of designs I even did myself.
