Preconstruction’s Smartest Move: The AI Advantage General Contractors & Subcontractors Can’t Ignore Anymore

Let’s face it, construction has never been short on hard work. But hard work doesn’t fix broken bid cycles.

It’s the workflow.

Bids are still getting bottlenecked at the takeoff stage.

Estimators are still tracing lines and cleaning Excel sheets. And that’s costing contractors the one thing they don’t have: time.

Meanwhile, other industries are using AI to automate grunt work, scale output, and move faster.

So why is pre-construction still stuck?

The truth is: AI isn’t the problem. The mindset to adopt it late is.

The smartest general contractors and subcontractors are switching to AI-based construction takeoff software such as Beam AI, and watching productivity, bid volume, and revenue soar like never before.

Let’s break down how it’s happening.

 

Let’s Start With the Problem (That’s Costing You Bids)

Ask any general contractor or subcontractor and they’ll tell you the same thing: the bottleneck isn’t skill. It’s time. Or the lack of it.

• Average estimator wastes 1,040 hours a year on manual takeoffs
• Manual takeoffs still consume up to 50% of the bid cycle
• Estimators are buried in the manual grind
• Bid turnaround is slow, and supplier quotes come in late
• GCs struggle to finalize packages because subs are backed up

Manual workflows limit how many bids your team can submit. They delay your ability to respond to addenda.

If you’re still operating like this, you’re not just losing time—you’re leaving money on the table.

 

AI Isn’t a Threat. It’s a Force Multiplier.

Let’s clear something up: AI isn’t here to replace estimators.

It’s here to give them time back—to negotiate with vendors, refine pricing, and build better bids.

Think of it like this: CAD didn’t replace architects. It replaced drafting tables.

Similarly, AI-based construction takeoff software like Beam AI is flipping the script. It’s removing the need for clicking through 40 sheets a day.

By automating quantity takeoffs across 15+ trades and delivering them in 24–72 hours, Beam AI doesn’t just extract quantities. It scans every sheet to catch keyed-in spec notes, scope requirements, and general instructions, just like an estimator would. Here’s what estimators get with Beam AI:

• Auto-detection of addenda changes across plan versions
• Accuracy guaranteed within ±1% of in-house takeoffs
• Excel-ready exports tailored to your estimating workflow

900+ businesses using Beam AI are saving up to 90% of their time on takeoffs, and as a result, they’re bidding for 2X more jobs.

But the real story? What they’re doing with that saved time.

 

How General Contractors Are Gaining the Edge with AI Takeoffs

Pilkington Construction Co.

As a GC, Pilkington struggled with bid delays. Using tools like Bluebeam and OST, takeoffs would take 3–4 days per project, leaving estimators with little time for collaboration or quality control.

After adopting Beam AI:

• Takeoffs that used to take a full week now require just a quick review in a few hours
• Estimators have more time to engage subcontractors and sharpen bids
• Bid accuracy has improved, reducing errors and missed scope
• Most importantly, they saw 1.5X business growth with more submissions and stronger deal closures

Pilkington’s team didn’t grow in size. They grew in output.

“In reality what you guys are doing saved me is… a week’s worth of work.” –— Lead Estimator, Pilkington Construction

 

How Subcontractors Are Doubling Down on Growth with AI

Rays Stairs Inc.

For steel subcontractor Rays Stairs Inc., takeoffs were a huge time sink—18+ hours per week, just for one estimator.

The team could only manage 5 bids per week, and that cap was throttling revenue growth.

Post-Beam AI?

• Bid volume doubled from 5 to 10 bids per week
• Takeoff time dropped by 18 hours per week—saving 2 full workdays
• They won 10 new projects in one month
• Their win rate jumped from 3–4 to 6–7 projects a week
• Revenue skyrocketed from $900K to $2M in just 2 months

Beam AI didn’t just save them time, it unlocked bidding opportunities they never had the bandwidth to pursue.

“I think it’s a really easy software to use. Anybody that can pretty much send an email, I think can learn how to use it within a week.” –Estimating Lead, Rays Stairs

Legacy HVAC

Legacy was using Bluebeam for takeoffs, spending 4–6 hours per page. It took 3 to 5 days to prepare a single bid.

The lengthy bid prep slowed down how many projects they could actually go after and win.

With Beam AI:

• Takeoff time was slashed by 80%
• What once took hours now takes minutes to review
• Productivity soared by 60%, freeing up teams to handle more bids and focus on change orders
• Legacy’s revenue grew from $6M to $12M within a year

And it didn’t require more staff. Just smarter software…

 

Across Trades, One Thing’s Common: Faster Bids with Beam AI

Beam AI isn’t just built for one trade, it’s transforming estimating across the board.

1- Bommarito Construction, a utility construction subcontractor, unlocked $1M in new revenue and submitted 50 more bids in 6 months.

2- Desert Rat Welding, a Utah-based steel fabrication and welding firm, slashed 80% of takeoff time—and went after bigger jobs.

3- Rocky Mountain Steel, a structural steel subcontractor, saved 15 hours a week on takeoffs and boosted bid volume.

4- JBG Flooring, a flooring subcontractor, reduced takeoff time and increased bid volume by submitting faster, more competitive bids.

5- Merritt Contracting, a concrete and civil construction company, saved 8 hours a week and kept bid accuracy sharp by automating takeoffs.

No matter the trade, one thing’s clear: takeoffs don’t have to be the bottleneck anymore.

 

Why Beam AI Works

Beam AI isn’t just another takeoff tool. It does the takeoffs, an expert estimator reviews them, so you get takeoffs in 24 to 72 hours.

• Supports 15+ trades
• Reduces takeoff time by 90%
• Enables teams to send 2X more bids
• Delivers reviewed takeoffs within 24–72 hours
• Lets estimators focus on high-impact tasks—not PDF tracing

It’s what happens when construction tech actually works for construction people.

When tech adapts to real workflows, the results speak for themselves. Time back, bids up. That’s real pre-construction tech.

 

The Takeaway: When Estimators Get Time Back, Bids Go Up 2X

The shift is already happening.

Manual estimating workflows are on their way out. And the contractors embracing AI today are the ones outbidding, outpacing, and outperforming everyone else.

GCs like Pilkington. Subs like Rays Stairs and Legacy. They didn’t wait for AI to become “normal.” They used it to win big.

And now it’s your move.
