Artificial Intelligence Is Here—Now What?
“AI!…Huh!…Good God, y’all…What is it good for?”
If you’re old enough, you probably recognize that famous line from Edwin Starr’s classic song War.
When people ask me about Artificial Intelligence, I can’t help but think about that song.
Some people believe AI will completely replace electrical estimators.
Others believe it is nothing more than another marketing gimmick.
After spending more than 50 years in the electrical industry, I believe the truth lies somewhere in the middle.
I use AI almost every day.
Recently AI helped me solve a computer problem that had frustrated me for weeks. It also helped me diagnose a problem on my lawn mower that refused to start.
Did AI fix my computer?
No.
Did AI replace the bad part?
No.
Did AI walk into my shop with a toolbox, crawl around on the floor, read the voltmeter, loosen bolts, or turn a wrench?
Absolutely not.
AI gave me ideas.
AI helped me think.
I still had to do the work.
That is exactly where AI belongs in electrical estimating.
Why Everyone Wants AI to Estimate for Them
Every software company today seems to promise the same thing.
“Push a button and let AI estimate your project.”
That sounds wonderful.
Unfortunately, electrical estimating doesn’t work that way.
People want AI because they believe it will:
- Count every symbol automatically.
- Measure every conduit run.
- Build a complete estimate.
- Produce the perfect bid.
- Save hours of work.
The problem is this…
Estimating isn’t just counting.
Estimating is making decisions.
Those decisions determine whether you make money—or lose money.
No software, no matter how intelligent, understands your company the way you do.
It doesn’t know your crews.
It doesn’t know whether you’re working with apprentices or master electricians.
It doesn’t know how efficiently your foreman installs conduit.
It doesn’t know whether the engineer consistently over-designs projects.
It doesn’t know your local suppliers.
It doesn’t know whether copper prices have changed dramatically this week.
Most importantly…
It doesn’t know your company.
AI Is an Assistant—Not an Estimator
One of the biggest mistakes I see contractors make is expecting AI to replace knowledge.
Knowledge cannot be downloaded.
Experience cannot be automated.
Judgment cannot be programmed.
AI should never replace the estimator.
It should assist the estimator.
Think about a calculator.
Calculators have existed for decades.
Nobody would argue that calculators replaced accountants.
They simply made accountants faster.
AI should do exactly the same thing for electrical estimating.
Use it to save time.
Use it to organize information.
Use it to verify your work.
Never use it to replace your thinking.
The Danger of Blindly Trusting AI
One bad estimate can wipe out the profit from several successful jobs.
That is why I become concerned when I hear people say…
“The software estimated it.”
That statement should make every contractor nervous.
Before you submit a bid you should understand exactly how every important number was created.
If AI counted 400 receptacles…
Can you verify them?
If AI measured 12,000 feet of conduit…
Can you prove it?
If AI identified every lighting fixture…
How do you know it didn’t confuse one fixture with another?
The answer is simple.
You verify.
Every.
Single.
Time.
The Art of Balance Between AI and Experience
One of the most important lessons I’ve learned over my career is that success usually comes from balance.
Too much confidence can hurt you.
Too much fear can hurt you.
Too much technology can hurt you.
Too little technology can hurt you.
The contractors who succeed over the next decade won’t reject AI.
They also won’t blindly trust it.
They’ll find the proper balance between technology and experience.
I discuss this philosophy in much greater detail in my article:
The Art of Balance in Electrical Estimating
https://bestbidestimating.com/art-of-balance-electrical-estimating/
Technology should make you a better estimator.
It should never replace becoming one.
Why Every Estimator Must Learn the Fundamentals
Many people want software because they don’t want to learn estimating.
That is backwards.
Software should speed up what you already understand.
Imagine hiring someone who cannot read blueprints but owns the world’s best estimating software.
Would you trust their bid?
Neither would I.
You need to understand:
- Labor
- Material
- Difficulty
- Installation methods
- NEC requirements
- Crew productivity
- Risk
- Material handling
before you allow software to help you.
Learning estimating is never wasted knowledge.
No one can take it away from you.
Understanding Auto Count Technology
Auto Count has improved tremendously over the past several years.
At Best Bid, we have spent years developing and improving our own hybrid Auto Count technology.
Many competitors rely on one of two basic approaches.
The first searches for symbols that look exactly alike.
It works well until the symbol is rotated, mirrored, partially hidden, or drawn differently.
The second approach attempts to learn an entire symbol library.
This can be very impressive.
Until it isn’t.
Sometimes the software counts everything.
Unfortunately, it also counts the wrong things.
A duplex receptacle becomes a GFCI.
One light fixture becomes another.
Everything gets highlighted.
Everything looks correct.
But underneath…
The count is wrong.
That is one of the biggest dangers with automatic counting.
Wrong answers often look very convincing.
Why AI Still Misses Electrical Symbols
People often tell me…
“My drawings look perfect.”
Looking perfect and being perfect are two completely different things.
AI has no common sense.
It only understands what it can see.
If the drawing quality changes…
The count changes.
If symbols overlap…
The count changes.
If the engineer uses different symbols…
The count changes.
If resolution changes…
The count changes.
This isn’t because AI is bad.
It simply has limitations.
Vector Drawings vs. Scanned Drawings
One of the biggest misunderstandings in our industry is the difference between vector drawings and scanned drawings.
Vector drawings contain mathematical information.
Scanned drawings contain pictures.
That difference is enormous.
Vector drawings allow software to identify lines, circles, symbols, and text with incredible precision.
Scanned drawings are simply millions of colored pixels.
When contractors tell me,
“The drawing looks great on my screen.”
that tells me absolutely nothing.
Many beautiful drawings are terrible for automatic counting.
Before running Auto Count, always perform two simple tests.
The Zoom Test
Zoom in extremely close.
If the lines stay perfectly sharp…
You probably have a vector drawing.
If the lines become fuzzy blocks…
You’re looking at a scanned image.
The Text Test
Try selecting text.
If individual letters can be highlighted…
You probably have a vector drawing.
If the entire page acts like one giant photograph…
You’re working with a scanned drawing.
Understanding this one concept can save hours of frustration.
How to Get Better Results From AI
If you really want AI to help you, follow these rules.
- Use the best drawing quality available.
- Request vector PDFs whenever possible.
- Verify every automatic count.
- Never trust one click.
- Always review highlighted symbols.
- Compare counts against your own expectations.
- Use AI to speed up your work—not replace it.
Doing these things will dramatically improve your accuracy.
My Personal Experience After Testing AI
I’ve spent years testing AI.
I’ve tested nearly every major automatic counting approach available.
Some are impressive.
Some are disappointing.
Some fail completely.
Our own hybrid Auto Count technology at Best Bid works on many scanned drawings and recognizes symbols in different orientations better than most systems available today.
Even with that success…
I still tell every customer exactly the same thing.
Don’t buy software because of Auto Count.
Buy software because it makes you a better estimator.
Many of our customers use Auto Count every day and absolutely love it.
Others rarely touch it.
The difference isn’t the software.
The difference is knowing when AI helps and when experience should take over.
That judgment only comes from learning the trade.
Frequently Asked Questions
Can AI estimate an electrical project?
No.
AI can assist an estimator, but it cannot replace experience, judgment, labor knowledge, and business decisions.
Is Auto Count 100% accurate?
No.
Every automatic counting system requires verification.
Why are vector drawings better?
Because vector drawings contain mathematical objects instead of pixels, making symbol recognition dramatically more accurate.
Should I trust AI-generated quantities?
Only after verifying them.
Never submit an estimate without reviewing the results.
Will AI replace electrical estimators?
I don’t believe so.
The best estimators will simply become faster because they’ll know how to use AI correctly.
Final Thoughts
Artificial Intelligence is one of the greatest tools our industry has ever seen.
It can save hours.
It can reduce repetitive work.
It can improve consistency.
It can even make you a better estimator.
But only if you remember one simple truth.
AI does not build the estimate.
You do.
Software doesn’t make contractors successful.
Knowledge does.
Experience does.
Discipline does.
Technology will continue to evolve.
The contractors who succeed won’t be the ones who blindly trust AI.
They’ll be the ones who combine modern technology with decades of proven estimating principles.
That is where real success lives.
That is the future of electrical estimating.
And that is the true Art of Balance.
