The Week We’re All Irish: From Bridges to Broadband, the Irish Keep Building
Learn how Bulk Exchange's construction technology can streamline your projects, save you time and money & revolutionize the way you manage bulk material!
Ahhh, St. Patrick’s Week, the one time of year when everyone suddenly discovers their long-lost Irish granny, and Guinness sales mysteriously triple. It’s a grand time altogether, with parades, pints, and questionable attempts at an Irish accent. But beyond the shamrocks and shenanigans, it’s worth remembering the deeper legacy of the Irish in America, one not just built on celebrations, but on sheer grit, resilience, and the ability to build things that last.
As a proud Irish American with deep roots in both tech and construction, I don’t just celebrate my heritage, I walk on it, work with it, and build upon it every day. The Irish didn’t just show up for the craic (though let’s be honest, we do love a good party). When Irish immigrants landed on these shores, they got straight to work, designing and constructing the backbone of this country. From the White House to the Golden Gate Bridge, from tunnels to towering skyscrapers, the Irish left their mark. Not with riches or privilege, but with sheer determination, strong backs, and the unshakable belief that they could build something better in their chosen home and country.
Fast forward a century or two, and the Irish are still at it. Instead of just building roads and bridges, we’re laying the foundation for the digital world. Paul Foley, my own CEO at Bulk Exchange and a proud son of County Leitrim, is part of that new wave, building the construction tech infrastructure that powers our modern economy. And let’s not forget the Collison brothers, two lads from rural Ireland who founded Stripe and reshaped online payments globally. Whether it’s steel and concrete or code and connectivity, the Irish spirit of resilience and innovation hasn’t changed and we’re still getting the job done.
Why are the Irish so good at this? Maybe it’s because we’ve always known how to push forward, no matter the odds. Whether it was swinging hammers or writing lines of code, the same qualities that built America’s physical landscape are now shaping its digital future: toughness, adaptability, and an innate ability to solve problems (usually with a bit of charm thrown in for good measure).
So this week, when you raise a glass at the parade, take a moment to remember, there’s a good chance the road you traveled to get there, and the tech you used to plan or pay for your night out, have the Irish to thank. Sláinte to the builders, past, present, and future!

Redefining Value: From Life Choices to Construction Materials
In our daily lives, we constantly make value judgments. We assess the quality of experiences, relationships, and purchases based on certain criteria: durability, reliability, consistency, and long-term satisfaction rather than momentary pleasure. Yet when it comes to construction materials, the literal foundation of our built environment, we sometimes lose sight of these value metrics in favor of immediate cost savings.
The True Definition of Value
Value isn't simply about the lowest price point. True value encompasses performance, longevity, reliability, and increasingly, sustainability. Just as we wouldn't choose a friendship based solely on convenience, we shouldn't select construction materials based solely on acquisition cost.
"The construction materials industry is rapidly evolving beyond the outdated paradigm of choosing materials based on initial cost alone," says Michael Philipps, former President of the National Ready Mixed Concrete Association (NRMCA). "Today's definition of value must include resilience, sustainability, and total lifecycle performance. The cheapest option upfront often becomes the most expensive over time."
In the world of bulk construction materials, value manifests in specific, measurable ways:
Consistent gradation ensures predictable performance across batches. When aggregates maintain uniform size distribution, the resulting concrete or asphalt delivers reliable strength properties.
Cleanliness of materials prevents contamination that can compromise structural integrity. Foreign substances in aggregates can inhibit proper bonding and accelerate deterioration.
Durability translates directly to reduced maintenance costs and extended service life. Materials that resist weathering, abrasion, and chemical attack provide significantly greater long-term value.
Strength determines load-bearing capacity and resistance to failure. Higher-quality materials typically offer superior strength-to-weight ratios, enabling more efficient designs.
Adherence to ASTM and DOT specifications provides verified quality assurance. These standards represent industry consensus on minimum acceptable performance criteria, formed through rigorous testing and real-world experience.
"Quality aggregates are the backbone of resilient infrastructure," observes Karen Hubacz, Chairwoman of the National Stone, Sand & Gravel Association (NSSGA). "When we talk about extending the service life of our roads, bridges, and buildings, we're really talking about starting with materials that meet or exceed specifications. The difference between marginal materials and premium aggregates can mean decades of additional service life."
The Future of Value: Sustainability Meets Performance
The construction industry stands at a critical juncture. Climate change and resource scarcity demand that we reconsider how we define value in building materials. Fortunately, innovation is already providing solutions that harmonize performance with environmental responsibility.
Portland Limestone Cement (PLC) exemplifies this evolution in value. By replacing a portion of clinker with fine limestone, PLC reduces carbon emissions by 10% compared to traditional Portland cement while maintaining equivalent performance. This isn't just an environmental win—it's economically sound, as reducing clinker content lowers production energy requirements.
"PLC represents the kind of innovation that's transforming our industry," says Tom Beck, Executive Vice President of Summit Materials. "We're seeing materials that not only reduce environmental impact but actually outperform their traditional counterparts in many applications. This is the future of construction – where sustainability and superior performance go hand in hand."
Other innovations are rapidly transforming our options:
- Geopolymer concretes utilizing industrial byproducts like fly ash and slag
- Carbon-sequestering concrete that actually absorbs CO₂ during curing
- Mass timber products offering renewable alternatives to steel and concrete
- Recycled aggregate concrete reducing the need for virgin material extraction
"The asphalt industry has long been at the forefront of recycling and material innovation," notes Audrey Copeland, President and CEO of the National Asphalt Pavement Association (NAPA). "Today's high-performance asphalt mixes incorporate recycled materials while delivering longer-lasting, smoother, quieter roadways. This combination of sustainability and enhanced performance is redefining what value means in infrastructure construction."
The true breakthrough is that these sustainable alternatives aren't just "green options"—they're increasingly becoming the highest-performing, most economical choices. Much like LED lighting has surpassed incandescent bulbs in both performance and cost-efficiency, sustainable construction materials are poised to redefine value in the building industry.

Overcoming the Knowledge Gap
The shift toward higher-value, sustainable materials faces one significant obstacle: awareness and access. Contractors, engineers, and project managers often default to familiar materials not because they prefer them, but because they lack information about alternatives and where to source them.
"One of our greatest challenges is connecting innovative products with the professionals who specify and use them," explains Rex Cottle, Executive Director, The National Steering Committee (NSC) - Concrete Industry Management (CIM). "We can develop the most sustainable, high-performance materials in the world, but they only create value when they're actually used in construction."
This knowledge gap represents perhaps the greatest barrier to adopting higher-value materials. How can professionals specify innovative products if they don't know these products exist or where to find them?
Bulk Exchange has emerged as the solution to this critical challenge. As the first and only complete directory of construction materials, Bulk Exchange enables professionals to discover, compare, and source next-generation materials in their local area. This platform bridges the information gap, making it easier than ever to select high-value materials for any project.
By providing comprehensive information on material properties, sustainability metrics, and local availability, Bulk Exchange empowers builders to make truly value-based decisions. The platform transforms the abstract concept of "better materials" into concrete actions: specifying PLC instead of traditional cement, selecting recycled concrete aggregate, or choosing locally-sourced materials to reduce transportation emissions.
The infrastructure we build today will serve communities for decades to come. By leveraging tools like Bulk Exchange to identify and source the highest-value materials, we're not just constructing buildings and bridges—we're creating a legacy of sustainability, performance, and true economic value. For the projects of tomorrow, choosing high-value materials isn't just preferable—it's essential. And now, with Bulk Exchange, it's also achievable.

What “Buy Local” Really Means in Construction
Why Local Knowledge, Not Just Local Goods, Is the Key to Profitability, Sustainability, and Growth in Heavy Civil
By Rachael Mahoney, Chief Strategy Officer at Bulk Exchange
We’ve all seen the signs: Buy Local.
It’s in shop windows. Plastered on billboards. Preached by every chamber of commerce, economic development office, and tourism campaign from New York to New Zealand. We use it to market everything from farm-fresh eggs to five-star resorts—and it works. Studies have shown that buying local keeps up to 68% more money in the local economy, fosters community resilience, and reduces environmental impact.
But in commercial and heavy civil construction, “buy local” has a very different, and far more literal meaning.
Because in this world, local isn’t about zip codes. It’s about tonnage, travel time, and trust.
It’s about sourcing 20,000 tons of rock from 10 miles away instead of 60. It’s about knowing which landfill will take concrete but not clay. And it’s about understanding the hyperlocal logistics that can make or break a job.
In our industry, local knowledge is everything.
The True Cost of Not Sourcing Locally
If you work in construction, you already know this: transportation is often the biggest cost driver in your bulk materials budget. Not the material itself. Not labor. Hauling.
Moving 15,000 tons of base rock just 25 miles instead of 50 can mean the difference between profit and red ink.
According to Bulk Exchange platform data:
- Transport costs can account for 60–80% of the total delivered cost of bulk materials
- Every additional 10 miles of haul distance can add $1–$3/ton to the final price
- Over the course of a large job, that can mean hundreds of thousands of dollars lost
And that’s just the financial cost. There’s also the human cost.
“We had drivers sitting in traffic for over an hour because of local delivery restrictions. We missed the pour window, and it put us behind three days,” one project manager in Los Angeles told us. “If we’d sourced 10 miles closer, we’d have finished early.”
These inefficiencies impact worker morale, job site momentum, and project timelines, especially when margins are earned on the completed job, not the hours spent getting materials to it.

Buying Local Isn’t Easy in Heavy Civil—But It Should Be
Here’s the catch: while every contractor wants to source locally, it’s not always easy, especially when you’re working outside your home market or scaling into new regions.
It takes deep, local knowledge to know:
- Who actually has the material you need
- If you can rely on their reputation
- What their gate rates and specs are
- When they’re open and how much capacity they have
- Whether their permits, restrictions, or truck routes fit your timeline
Most of that information isn’t online. And when it is, it’s scattered across outdated websites, voicemail boxes, and personal networks built over decades.
And that’s where things get risky.
The lack of transparency creates fertile ground for brokers or bad actors to take advantage—marking up rates, withholding information, or intentionally slowing down communication to control the transaction.
In many cases, contractors are forced to rely on intermediaries simply because they don’t have direct access to local knowledge. What should be a straightforward material order turns into a game of telephone, with every hop along the chain adding cost, delay, or uncertainty.
When information isn’t accessible, efficiency takes a backseat to gatekeeping.
And that doesn’t just affect pricing, it undermines scheduling, job planning, and margin in ways that are hard to measure but deeply felt.
“I’ve seen brokers tack on $5–10 per ton just because they knew we were out of market and up against a deadline,” one estimator told us. “By the time you find out, it’s too late—you’ve already bid or booked trucks.”
For too long, local sourcing has been gatekept by geography and opacity. If you weren’t from the area, you didn’t have the intel—and that meant higher risk, higher costs, and higher friction.
“Sourcing Like a Local”: The New Competitive Advantage
This is where technology becomes essential. At Bulk Exchange, we’re not just building a platform, we’re building a way to make local knowledge accessible anywhere.
Our marketplace gives contractors the power to:
- Search by material, location, and availability in real time
- Compare gate rates, capacity, specs, and distance in one place
- Directly connect with site contacts, bypassing gatekeepers
- List or match excess materials nearby, enabling reuse and reducing waste
“We sourced both import and export sites within 48 hours using Bulk Exchange. One was five miles from the site—we had no idea it was there,” said a senior estimator from a regional contractor in Texas. “That match saved us over $30K on the first phase alone.”
When you source like a local, you reduce risk, improve margins, and gain flexibility. You make smarter routing decisions. You build stronger subcontractor relationships. You eliminate painful surprises. And, perhaps most importantly, you create space to expand without the usual growing pains of entering new markets.
The Environmental Impact of Local Sourcing
In an industry facing increasing scrutiny and regulation on carbon emissions, local sourcing also has a huge role to play in sustainability.
Every extra mile traveled by a heavy-duty truck means more:
- Diesel consumption
- Traffic congestion
- Carbon emissions
And as we begin integrating newer, more sustainable materials—from low-carbon concrete mixes to recycled aggregates—the logistics become even more time and distance sensitive. These materials often have shorter working windows or specific storage conditions, making precise planning essential.
“You can’t use low-carbon concrete if it’s been sitting in a drum for two hours in summer heat,” one project engineer told us. “Local sourcing isn’t just cheaper. It’s necessary if we want to hit our sustainability targets.”
According to Bulk Exchange estimates, local sourcing can reduce material-related emissions by 25–40%, depending on haul distance and vehicle type.
The Future of Construction Is Local + Digital
“Buy local” is no longer just a slogan…it’s a strategic imperative for construction. But it’s time we expand what that really means.
It’s not just about supporting local suppliers (though that’s important). It’s about empowering contractors—wherever they are—to access local knowledge, make smarter sourcing decisions, and complete jobs with fewer delays, lower costs, and less environmental impact.
And the only way to do that at scale is with technology, and the willingness to adopt it.
Bulk Exchange is unlocking the ability to “source like a local” on every job, whether you’re in your home market or hundreds of miles away. That changes everything.
It de-risks expansion, improves margins, supports sustainability, and reduces friction for everyone, from planners and estimators to drivers and crews.

Why Are We Still Using Google to Source Rock?
The construction industry still relies on outdated methods like Google searches to source rock, spreadsheets, and cold calls, leading to wasted time and cost. Bulk Exchange is a digital marketplace specifically designed for bulk materials sourcing. Our platform aims to reduce wasted materials, cut costs, and modernize outdated workflows.
By Rachael Mahoney, Chief Strategy Officer at Bulk Exchange
We live in a world where we can get a refrigerator delivered tomorrow with the tap of a finger. We can order shoes, sushi, or dog food and track it to our door in real time. Marketplaces have completely reshaped how we buy, sell, and connect.
But if you're an estimator trying to find 15,000 tons of fill or a disposal site for a few thousand cubic yards of contaminated soil?
You're still relying on Google. Maybe a spreadsheet. Probably a few cold calls. And a whole lot of waiting.
It’s wild, isn’t it? In one of the most essential and material-intensive industries on the planet, we’re still using tools that were never designed for us. And it's not just inconvenient—it’s costing us in time, money, and talent.
The Time Sink No One Talks About
Every sourcing professional I know are wildly skilled problem solvers with engineering minds and decades of collective experience. But ask any of them how much of their day is spent just trying to source or dispose of materials for a bid or project, and you’ll get the same eye roll.
“I spend about a third of my day just trying to track people down,” one estimator recently told us. “It’s all Google searches, phone tag, and out-of-date info. It’s incredibly inefficient.”
According to research from Dodge Leads and LetsBuild, it’s not uncommon for planners and estimators to spend 30–40% of their time on this one task alone. That’s 14 to 16 hours a week chasing down answers to questions that should take minutes:
- Who has the material I need?
- Can they deliver?
- What are their gate rates?
- Do they have capacity?
- Who’s the actual person to talk to?
This is one of the most foundational pieces of project planning, and yet it remains one of the least supported by technology.
Heavy Civil Construction: A Critical Industry, Missing a Critical Tool
Heavy civil construction builds the systems our entire world runs on—transportation, water, energy, public works. We are literally moving earth to make progress. But our sourcing workflows are stuck in the past.
"We're using million-dollar equipment, managing hundred-million-dollar projects, and still relying on fax machines and cold calls to move dirt." — Project Executive, Bay Area
Every other major industry has modernized its supply chain. Why haven’t we?
The truth is: we haven’t had a centralized marketplace—until now.
Introducing Bulk Exchange: A Marketplace Built for Us
That’s why we built Bulk Exchange—the first and only digital marketplace designed specifically for bulk materials in heavy civil construction.
This isn’t a directory. It’s a living, breathing, searchable ecosystem where suppliers, disposers, and contractors can:
- Search real-time inventory and gate rates
- Find nearby import/export matches
- Check site capacity and material specs
- Communicate directly with site contacts—no middlemen
It’s the platform our industry deserves: simple, transparent, cost-effective, and built for the realities of civil work. One that saves time, trims costs, and opens the door to a more sustainable, circular economy for construction materials.

How the Old Way Hurts Our Future
If the time suck wasn’t enough, there’s another side to this story: talent.
We’re in the middle of a historic labor shortage. According to the AGC, over 85% of construction firms are struggling to find qualified workers, and the younger generation isn’t exactly lining up to take their place.
Why?
Because we’re asking digital natives to work in analog environments. And frankly, they want no part of it.
“It’s not that I don’t want to work in construction,” a recent construction management grad told us. “It’s that I don’t want to work somewhere that still uses fax machines.”
Our reliance on outdated workflows doesn’t just create inefficiencies, it actively repels the next generation of talent. New grads are used to intuitive, data-driven platforms in every aspect of life. Expecting them to spend half their day chasing gate rates over the phone isn't just inefficient, it's a dealbreaker.
Circular Construction Starts with Visibility
We talk a lot about sustainability in this industry but you can’t optimize what you can’t see.
Without a centralized platform, we’re missing daily opportunities to reuse materials, cut haul distances, and keep resources in motion instead of in landfills. According to our white paper, over 70% of excess spoils are wasted or hauled long distances simply because contractors didn’t have visibility into nearby reuse options.
Bulk Exchange changes that. We’ve seen contractors:
- Cut sourcing time by 60%
- Avoid 4+ hours of haul time per load
- Save tens of thousands of dollars by matching with local suppliers or disposers in a single click
And those aren’t just wins for the bottom line—they’re wins for the planet, too.
It’s Time to Stop Making Phone Calls for Rock
This isn’t just about saving time…it’s about moving the industry forward.
Let’s give our people the tools they need to work smarter. Let’s make it easier to do the right thing, whether that’s reusing materials, shortening hauls, or just getting a job priced faster.
Let’s stop wasting world-class talent on low-value admin work, and start giving them back their time.
At Bulk Exchange, we’re not just building a platform—we’re building a better way to work.
