This interview is with Mario Barnes, Owner, EM Contingency Group LLC.
Mario, as the Owner of a construction firm specializing in custom homes and residential development across Mississippi and Alabama, how do you introduce your company, your typical client, and the kinds of projects you build?
I own EM Contingency Group, a construction company operating across North Mississippi and North Alabama. We work in government contracting, commercial construction, and residential development. Our homebuilding division, Hexalon Homes, focuses on custom homes and residential communities.
My role has always been to look for gaps—whether that’s in housing, infrastructure, or something a community is missing—and figure out how to build a solution around it. On the residential side, we often work with families relocating for work, local buyers trying to stay in their communities, or landowners looking to turn raw property into usable housing where supply hasn’t kept up.
On the commercial and government side, we collaborate with agencies and organizations that need projects delivered correctly and efficiently, but I approach those the same way—identifying the need and then executing.
Some of the projects I’ve taken on don’t necessarily start as profit-driven decisions. Iuka Sports Academy is a good example. That was something I chose to build because there was a clear gap in the community, and I wanted to create something that added value locally. I’ve found that when communities have better infrastructure—whether that’s housing, recreation, or services—it naturally supports growth.
Housing, in particular, is one of the biggest drivers. You can bring in jobs, but if people don’t have a place to live, growth stalls. A lot of what I focus on now is using construction and development not just as a business, but as a way to help remove those bottlenecks and allow smaller communities to actually move forward.
Stepping back, what key experiences—from electrician work and construction engineering to project management and contract negotiation—most shaped your path to owning your own building company?
My path into construction really started in the Air Force as an aircraft electrician. That’s where I learned discipline and attention to detail early—when you’re working on aircraft, there’s no margin for error. From there, I transitioned into the IBEW electrical wireman apprenticeship, which gave me a strong foundation in the trade and eventually led to working as a journeyman electrician in Iraq.
Being overseas accelerated everything. I was promoted into roles as an inspector and auditor, where I wasn’t just doing the work anymore—I was responsible for making sure entire systems and installations were done correctly. That shifted my mindset from task-focused to outcome-focused. After that, I worked as an electrical consultant supporting AFCENT in Qatar, which exposed me to higher-level coordination, planning, and accountability on large-scale projects.
From there, I moved into project management roles, including working with KBRwyle on a NASA project and later managing work on a U.S. Embassy project in El Salvador with Futron. Those roles brought everything together—technical background, leadership, scheduling, budgeting, and dealing with real-world constraints across different environments and teams.
At the same time, I had already been working for myself for years, taking on projects and building experience on the business side. Over time, it became clear that I didn’t just want to manage pieces of projects—I wanted to control the full process, from concept to completion.
What shaped me the most wasn’t any single role, but the progression through all of them. Starting in the field, moving into inspection and consulting, then into full project leadership—you see where things break, where they succeed, and what actually matters. It teaches you that construction isn’t just about building something—it’s about accountability, problem-solving, and delivering results under pressure.
Owning my own company was the natural result of that path. It gave me the ability to apply everything I’d learned—across trades, management, and contracts—and build projects the way they should be done, while also taking on opportunities that I believe actually move communities forward.
Bringing that background to a new project, how do you structure pre-construction for a custom home in Mississippi or Alabama—feasibility, budgeting, design coordination, and permitting—in a way that protects cost and schedule, and what’s the one step you insist on before a client signs?
Pre-construction is where I’ve seen more projects go wrong than anywhere else, and most of the time, people don’t realize it until they’re halfway through the build. So, I put a lot of emphasis on getting that part right from the beginning.
The first thing I look at is feasibility, which comes from experience in the field. I’ve been on enough sites to know that what looks fine on paper can turn into a problem once you start moving dirt. In Mississippi and Alabama especially, you’ve got to pay attention to soil conditions, drainage, utilities, and access—those are the things that can quietly blow a budget if you don’t deal with them early.
From there, I like to walk clients through budgeting alongside the design. I don’t believe in letting someone fall in love with a set of plans and then telling them what it costs afterward. I’d rather adjust things as we go so we’re always staying grounded in reality.
Design coordination is really about putting a builder’s mindset on the plans. I’ve seen plenty of details over the years that look good but don’t make sense once you’re actually trying to build them. My job there is to simplify where needed, avoid unnecessary costs, and make sure the project can move efficiently once we break ground.
Permitting is something I try to stay ahead of. Every area is a little different, and I’ve learned it’s better to address those requirements early than to be sitting still later waiting on approvals.
At the end of the day, I’m trying to remove as many unknowns as possible before we ever start. That’s what protects both the cost and the schedule.
The one thing I won’t move forward without is a clearly defined scope tied to a realistic budget. That’s something I’ve learned over time—you can’t protect a client or a project if everyone isn’t on the same page about what’s being built and what it’s going to take to get there.
Once shovels are in the ground, how do you use tools like MS Project, Excel cost codes, and a disciplined change-order workflow to control budgets and expectations, and what’s one habit homeowners should adopt to avoid surprises?
Once we break ground, everything comes down to communication and keeping everyone aligned. If that breaks down, that’s when you start seeing issues with cost and schedule.
We run everything through Buildertrend. That’s where the schedule lives, where communication happens, where selections are tracked, and where all change orders are processed. It keeps everything in one place so there’s no confusion about what’s been decided, what’s been approved, and what’s coming next.
On the cost side, we still track things with detailed cost codes, but Buildertrend ties it all together in real time. The biggest advantage is transparency—clients can see what’s going on without having to guess or chase information.
Change orders are handled strictly through Buildertrend as well. If something changes, it’s documented, priced, and approved before we move forward. No side conversations, no verbal changes—that’s where projects get into trouble. Keeping that process centralized keeps expectations clear and avoids disputes later.
At the end of the day, the system works because communication is consistent. Buildertrend just makes that easier by keeping everything organized and visible.
If there’s one habit I’d tell homeowners to adopt, it’s this: stay engaged and communicate early. Ask questions, review updates, and don’t wait until something is already in progress to bring up a concern. The more involved and proactive you are, the smoother the project will go and the fewer surprises you’ll have.
Because execution depends on trade partners, how do you qualify, contract, and manage subcontractors across two states to ensure safety, quality, and schedule alignment, and what single criterion should clients look for in a builder’s trade network?
Execution really comes down to the people in the field, and that is where a lot of the value of a general contractor actually lies. You’re constantly filtering, evaluating, and adjusting your subcontractor base; it’s not something you set once and forget.
Across Mississippi and Alabama, we’re always qualifying subcontractors based on a few factors: reliability, quality of work, communication, and their ability to meet schedules. Price matters, but it’s not the first filter. The cheapest subcontractor will usually cost you more if they can’t perform.
We assess past performance, how they’ve handled other jobs, how they communicate during the bidding phase, and whether they show up and follow through. Once they are under contract, clear expectations regarding scope, schedule, and standards are defined up front.
Managing subcontractors is really about consistency: clear schedules, regular communication, and holding people accountable. If someone starts slipping, whether in quality or timeline, we address it early. If it becomes a pattern, we replace them. That is just part of maintaining a strong network.
The reality is, you’re never done building that network. Good subcontractors get busy, crews change, and markets shift. So we are always refining who we work with to maintain the right mix of dependable and reasonably priced partners.
If a client is evaluating a builder, the single biggest thing they should look for is whether that builder has a proven and reliable trade network, not just a list of names. A strong builder isn’t just managing a project; they are managing the people who actually execute it. That is where quality, schedule, and ultimately the success of the job are decided.
On the quality and compliance side, how do your inspection, QA/QC, and construction safety practices—shaped by work that includes an active DoD Secret clearance—translate into a residential quality-control plan, and what checkpoint do you encourage clients to personally verify at each phase?
Quality and compliance is something I’ve been trained in over time, especially working in environments where there’s zero tolerance for mistakes. Having held an active DoD Secret clearance and worked on federal and overseas projects, you operate under strict inspection, QA/QC, and safety standards. That mindset doesn’t go away when you move into residential—it carries over.
For me, quality control starts with structure. We don’t treat it as a one-time inspection at the end—we’re checking work at each phase. That includes verifying:
- Layout
- Foundation preparation
- Framing
- Rough-ins
- Finishes
It’s an ongoing process, not something you hope passes at the end.
Safety follows the same approach. A clean, organized job site and crews that understand expectations are essential. A lot of quality issues arise from rushed or disorganized environments, so maintaining control in the field directly impacts the end result.
The biggest lesson I’ve learned is that problems are easier to prevent than to fix. So we focus on catching issues early—before they get buried behind the next phase of work.
This is also something that’s constantly improving. Every project teaches you something—whether it’s a detail that needs to be tightened up or a better way to sequence work. We take that knowledge and apply it forward so each job runs cleaner than the last.
For clients, I always encourage them to personally verify one key checkpoint at each phase: what’s about to be covered up. Before concrete is poured, before drywall goes up, and before finishes are installed—those are the moments where visibility is highest and changes are still manageable. Once it’s covered, your options become limited. Staying engaged at those points gives them confidence in what’s behind the walls, not just what they see at the end.
Communication can make or break a custom build; what cadence and artifacts (look-ahead schedules, submittal logs, budget updates, progress videos) keep your clients confident, and which single report or template delivers the most clarity?
Communication is what makes or breaks a project. Most problems I’ve seen over the years weren’t because something couldn’t be built; they came from people not being on the same page.
We keep a consistent cadence through Buildertrend, which acts as the central point for everything: daily updates, schedule tracking, selections, change orders, and messaging. Clients aren’t left guessing where things stand. They can log in and see progress, photos, and what’s coming next.
We also make sure communication is proactive, not reactive. That means regular updates, progress photos, and keeping clients aware of upcoming decisions before they become urgent. If something needs attention, we address it early instead of letting it turn into a problem.
Artifacts like schedules, budget updates, and change orders are all tracked in the system, but the real value is that they’re all connected. You’re not looking at isolated pieces of information; you’re seeing how everything ties together in real time.
If I had to pick one thing that delivers the most clarity, it’s the live schedule tied to actual progress. That’s what sets expectations. If a client understands where the project is and what’s coming next, everything else—costs, decisions, timing—becomes easier to manage.
At the end of the day, consistent and clear communication builds trust. Buildertrend just gives us a way to keep that organized and visible so nothing falls through the cracks.
Beyond the jobsite, you’ve spoken about using AI to guide marketing; in the custom-home context, how are you leveraging AutoCAD, drones, short-form video, Google Business, and AI-assisted analytics to win work and set expectations, and what’s the one digital asset every Mississippi or Alabama builder should publish today?
We’re in the middle of a pretty big shift right now, moving toward using AI and digital tools to tighten up both how we win work and how we set expectations before a project ever starts.
On the front end, tools like AutoCAD and design software are helping us communicate ideas clearly, but the bigger change is how we present and document projects. We’re using drones and short-form video to show real progress, real sites, and real conditions, not just finished photos. That gives clients a much more accurate picture of what we do and what to expect.
On the marketing side, Google Business and online presence matter more than most builders realize. That’s where people are making decisions before they ever pick up the phone. We’re focused on consistently feeding it real content, projects, updates, and videos, so it reflects what we’re actually doing in the field.
Where AI comes in is tying all of that together. Instead of guessing what works, we’re starting to use AI-assisted tools to track engagement, understand what people are responding to, and refine how we present projects. It’s helping us move from just “posting content” to actually understanding what drives interest and trust.
Long-term, the goal is to have a system that runs in the background, capturing job site progress, turning it into content, and distributing it automatically. That creates a constant, accurate picture of our work without adding a lot of manual effort.
If there’s one digital asset every builder in Mississippi or Alabama should publish today, it’s simple: consistent, real video of their actual work. Not polished ads, but real projects, real progress, and real explanations. That builds trust faster than anything else, especially in smaller markets where reputation still drives most decisions.
At the end of the day, AI and these tools aren’t replacing anything; they’re just making it easier to show the truth about how you operate. And the builders who do that well are the ones who are going to stand out.
Looking 3–5 years ahead, what trends will most shape custom home building in Mississippi and Alabama—land availability, insurance pressure on the Gulf, material volatility, labor, interest rates, or energy codes—and what practical move should prospective owners make now to be ready?
Looking 3–5 years out, I think the biggest factor shaping custom home building in Mississippi and Alabama is going to be land and population movement, not in theory, but in very real terms along specific corridors.
Where I’m located, along the Huntsville–Memphis corridor, we’re already seeing the early stages of what’s coming. You’ve got major federal investment driving growth out of Huntsville, expansion at places like Northrop Grumman at the Tri-State Commerce Park, new job announcements like the 1,500 positions at the old rail car facility, and continued development with Amazon, data centers, and logistics infrastructure. That kind of job growth doesn’t stay contained; it pushes outward.
This area has been artificially depressed for a long time, and now it’s starting to catch up fast. As that happens, land that’s been overlooked or undervalued is going to get absorbed quickly. At the same time, you’ve got continued migration into the South, both from industry and from individuals, including retirees and “snowbirds” looking for a lower cost of living and milder winters.
On top of that, you still have pressure from material volatility. Lumber, fuel, and shipping have all been unstable since the pandemic and the expiration of the softwood lumber agreement with Canada, and I don’t see that fully normalizing. Labor is still tight, and interest rates will continue to influence timing, but they won’t stop growth in areas where jobs are being created.
So when you stack all of that together—job growth, migration, limited land in the right locations, and ongoing cost pressure—you end up with one clear trend: the cost of waiting is going up.
The most practical move a prospective owner can make right now is to secure land early and make decisions sooner rather than later. You don’t have to build immediately, but controlling a good piece of property in a growing area puts you in a completely different position than trying to find one after demand has already caught up.
The people who move early, before the growth fully shows up in pricing, are the ones who are going to benefit the most.
Thanks for sharing your knowledge and expertise. Is there anything else you'd like to add?
If there’s one thing I’d add, it’s that construction, especially in smaller and growing communities, isn’t just about building structures. It’s about solving problems that affect how people live and how areas grow.
I’ve seen firsthand that when housing, infrastructure, and community spaces fall behind, everything else slows down with it: jobs, investment, and quality of life. On the flip side, when those pieces are in place, growth follows.
A lot of what I focus on now is trying to stay ahead of that, whether it’s building housing where it’s needed, taking on projects that fill gaps in a community, or improving how we deliver projects through better systems and technology.
This industry is always evolving, and we’re in a period where things are changing quickly: costs, demand, technology, and expectations. The builders who adapt, stay disciplined, and focus on delivering real value are the ones who are going to last.
At the end of the day, I’m not just interested in building projects; I’m interested in building things that actually move communities forward.
