Why Armcorp Construction Leads Off ABC Ohio Valley’s New Member Spotlight Series

This is the first installment of ABC Ohio Valley’s Member Spotlight series—a recurring feature recognizing member firms whose work on the jobsite and in the community embodies the values of merit shop construction. We created this series because our 300-plus member network across 40-plus counties in Ohio, Kentucky, and Indiana includes contractors whose stories deserve to be told. Starting today, we’re sharing those stories with the people who matter most: fellow members, prospective members, and industry stakeholders invested in the future of construction in this region.

Armcorp Construction, Inc., headquartered at 8511 State Route 703 in Celina, OH, is the right firm to lead off. This general contractor has been a merit shop member since 2009, building a portfolio spanning healthcare, government construction, manufacturing, and higher education projects. The merit shop philosophy emphasizes hiring based on skills and performance rather than union affiliation, promoting a competitive environment in the construction industry—and Armcorp lives that philosophy day in and day out.

The numbers frame the stakes clearly. Approximately 9 out of 10 construction workers in the Ohio Valley region choose non-union employment. Yet we face an estimated 60,000-worker shortage over the next several years, driven by infrastructure demands, retirements from the aging workforce, and insufficient new entrants into the trades. Firms like Armcorp are part of the solution, pairing workforce development with veteran support and community reinvestment in ways that attract talent and build loyalty.

We write this from ABC Ohio Valley’s perspective, as insiders who see member firms up close. The tone is professional but grounded—no promotional fluff, just the specifics that matter to contractors evaluating how peer firms operate and grow.

Humanitarians of the Year: Tim and Mary Rosengarten’s Community Impact

In spring 2026, at the Celina-Mercer County Chamber of Commerce Annual Banquet, Armcorp founders Tim and Mary Rosengarten were named Humanitarians of the Year. This award honors a multi-year pattern of service in Celina and Mercer County, not a single event or isolated donation. The recognition specifically cited their consistent investment in those who serve—veterans and first responders who form the backbone of the communities where Armcorp operates.

Tim serves as President and Owner, while Mary’s involvement as co-founder emphasizes the family-led values that have guided the company since its founding. Their roots run deep in Celina, OH, and as Armcorp has grown from a local operation to a firm handling regional and national projects with 41 employees, that growth has always been paired with intentional community reinvestment. The Rosengartens haven’t treated success as separate from service—they’ve treated them as the same thing.

For ABC Ohio Valley members, this recognition signals something important. Merit shop contractors can build both strong balance sheets and strong communities. Financial success and community leadership aren’t competing priorities. Firms like Armcorp demonstrate that the values driving excellence on the jobsite—integrity, pride, dedication—translate directly into how contractors show up for the people around them.

Lots for Soldiers: A Veteran-Owned Foundation Close to Home

Lots for Soldiers is a veteran-owned foundation dedicated to acquiring residential lots and facilitating home builds for veterans and their families. Founded in 2012 by Greg Lightle, a Celina native and Army veteran, the organization has completed over 20 homes by 2026, with a geographic focus that includes Celina, OH, and surrounding Mercer County communities. The foundation emphasizes self-reliance through sweat equity and community partnerships—a model that aligns naturally with Armcorp’s own approach to work and service.

Armcorp’s support of Lots for Soldiers is ongoing and multifaceted. The firm provides financial contributions from company funds, volunteer labor from field crews on build days, office staff participation in administrative tasks, and in-kind construction expertise such as design consultations and material donations. In 2025, build events in Mercer County, Armcorp crews handled concrete pours and utility trenching, reducing costs by an estimated 15-20% per home through pro bono skilled labor.

This partnership connects to ABC Ohio Valley’s broader commitment to workforce development pathways for veterans entering the trades. Training programs in construction often combine classroom instruction and on-the-job training to ensure workers are well prepared for their roles. Veterans represent a key untapped pool for addressing the construction industry’s skilled labor shortage—nationally, only 10-15% of post-9/11 veterans enter construction. Merit shop initiatives like those championed by Armcorp help bridge that gap, creating pathways to careers as a journeyman electrician, carpenter, equipment operator, or superintendent.

Recognizing First Responders and Veterans at the Mercer County Fairgrounds

Armcorp’s community engagement extends beyond Lots for Soldiers. During the August 2025 fair season, the company donated a firearm to the Mercer County Fairgrounds Reverse Raffle—specifically reserved for a veteran or emergency responder, with no purchase required. This gesture reflected the firm’s hands-on approach to honoring those who serve.

Finance and Admin Manager Kirsten attended the event on behalf of Armcorp, personally congratulating winner Tom Knapke, a local veteran. The firearm transfer was completed in full compliance with Ohio and federal regulations, including ATF Form 4473 background check requirements via a licensed dealer. No risks or violations were reported.

This raffle donation represents one of many touchpoints that position Armcorp as embedded in local networks. Mercer County sees high volunteer firefighter and EMS participation—over 500 personnel countywide—and Armcorp’s consistent presence at community events reinforces a pattern of celebrating those who serve while supporting the facilities and programs that bring communities together.

From Celina to Federal Campuses: Armcorp’s Project Portfolio in Government Construction

Transitioning from community work to core business, Armcorp Construction, Inc. has built a strong reputation in government construction while remaining rooted in Celina, Ohio. The firm’s portfolio includes federal and VA projects, municipal facilities, public infrastructure, and military upgrades—demonstrating breadth from local Ohio work to national scopes.

Merit shop construction allows contractors to choose their workforce freely, which can lead to increased efficiency and productivity on job sites. For government work specifically, this flexibility enables faster hiring and adaptation to project demands. Armcorp operates as a merit shop contractor able to meet strict certified payroll requirements under the Davis-Bacon Act, labor compliance regulations, and OSHA safety standards typical of federal projects.

The firm’s historical projects include healthcare expansions, military upgrades, and manufacturing facilities. Their safety awards highlight a culture that reduces incidents below industry averages—construction’s national Total Recordable Incident Rate sits around 2.8, while merit shops often achieve rates below 2.0. This safety record directly supports their ability to win and deliver government construction work where compliance and worker protection are non-negotiable.

Case Study: Dayton VA Medical Center Dock Replacement

The Dayton VA Medical Center Dock Replacement, launched in late 2025, stands as one of Armcorp’s current flagship projects. It thematically aligns with the firm’s commitment to veterans and VA operations—a meaningful parallel to their broader veteran-focused community work. The project demonstrates Armcorp’s capability in federal and VA work, with the certified payroll and labor compliance demands those contracts carry.

The project began with the demolition of outdated dock structures and site preparation, including excavation and grading. Operating within an occupied healthcare campus demands precise phasing: work confined to off-peak hours, including nights and weekends; infection control barriers with HEPA filtration and negative pressure; life-safety coordination to maintain egress routes; and daily VA staff syncs to avoid disrupting patient care or deliveries.

Core improvements include upgraded loading dock infrastructure with wider bays, improved truck circulation, weather-resistant canopies, enhanced ADA accessibility, and logistics optimizations for materials handling. The upgrades are projected to deliver 30% faster loading times, improved weather protection, and long-term usability for VA staff and logistics teams.

Implementing a comprehensive safety program includes regular training, safety audits, and the establishment of safety committees, all of which have been proven to enhance compliance with safety regulations. On this project, that means job hazard analyses, pre-task planning for each phase, and coordination with VA safety personnel throughout the project. The administrative backbone includes certified payroll management that verifies 100% compliance with Davis-Bacon wage rates, averaging $35-50 per hour for trades, reducing audit risk and ensuring field teams can focus on quality and schedule.

Project leadership noted that phasing around 24/7 operations required weekly VA huddles and preemptive mock drills for truck maneuvers. Budget estimates for similar VA dock scopes range from $2-5 million, showcasing Armcorp’s federal capability amid the VA’s $20 billion-plus annual construction spend.

Behind the Scenes: Women in Construction Powering Armcorp’s Back Office

Armcorp’s participation in Women in Construction Week in March 2026 highlighted a reality that high-performing merit shop firms understand: construction success in government and VA projects is built as much behind the scenes as on the jobsite. Certified payroll errors can delay payments 30-90 days or trigger debarment. HR failures in a 60,000-worker shortage market mean losing talent to competitors. Financial missteps on bonding and insurance can disqualify firms from sizable bids.

The women leading Armcorp’s back-office operations ensure none of those failures happen. Merit shop reliance on female leaders runs 20-30% in administrative positions, above the industry average of approximately 15%, according to NAWIC data. At Armcorp, two leaders exemplify this strength: Rebekah, Accounting Administrator, and Kirsten, Finance and Admin Manager. Their roles are central to the firm’s capacity to deliver complex work reliably.

Rebekah: Certified Payroll and Compliance for Federal and VA Work

Rebekah serves as Accounting Administrator, managing the financial and regulatory backbone that keeps Armcorp’s government construction projects compliant. Her primary duties may sound routine on paper, but the stakes are anything but routine when federal audits and labor regulations are involved.

She manages credit card tracking, reconciling over 100 transactions each month and ensuring project expenditures are coded correctly and are auditable for both internal management and external review. Receipt collection and GAAP-compliant auditing fall under her purview, creating the paper trail that protects the company during reviews.

Her most critical responsibility is producing accurate, timely certified payroll reports for federal, VA, and other public projects. This means cross-verifying wage rates against Department of Labor Wage Determinations, confirming fringe benefits, and ensuring proper labor classifications on WH-347 forms submitted to VA portals and eMars systems. Davis-Bacon violations carry fines up to $10,000 per misclassification—Rebekah’s accuracy prevents those risks while allowing field teams to focus on safety and quality rather than paperwork.

Kirsten: Finance, HR, and Administrative Leadership Across the Firm

Kirsten serves as Armcorp’s Finance and Admin Manager, sitting at the intersection of financial operations, human resources, marketing coordination, and administrative leadership. Her oversight touches nearly every aspect of how the company operates.

On the financial side, she manages budgeting and cash flow projection—targeting the 10-15% margins typical of government contracts—along with bonding and insurance coordination for surety lines on $10 million-plus bids. Financial reporting flows from QuickBooks through CPA audits under her direction, supporting Armcorp’s ability to pursue and deliver sizable government construction projects.

Her HR responsibilities are equally critical. She leads recruiting and onboarding, bringing on 10-15 new employees annually through channels such as Indeed and ABC job boards. Benefits administration, including 401 (k) matching, employee development coordination for safety training and veteran transitions, and reinforcing a workplace culture that attracts and retains skilled trades in a tight labor market—all fall under her leadership.

Kirsten also handles marketing coordination and community engagement logistics, including representing Armcorp at events like the Mercer County Fairgrounds Reverse Raffle. Her career path illustrates the professional development opportunities available to women in construction beyond purely field roles, aligning with ABC Ohio Valley’s emphasis on Next Gen Leaders programming.

Armcorp Construction and the Merit Shop Workforce: Building Capacity in a 60,000-Worker Short Market

The construction industry is facing a skilled labor shortage, making workforce development initiatives critical for attracting and retaining talent. In the Ohio Valley region specifically, we’re short an estimated 60,000 construction workers over the next several years—even as infrastructure and government construction demand remains strong. This isn’t a distant problem. It’s the reality every member firm navigates when staffing jobs today.

Approximately 9 out of 10 construction workers here choose to work in open-shop, non-union environments. This makes merit shop contractors like Armcorp central to meeting the region’s project needs. The merit shop approach is designed to foster innovation and cost-effectiveness in construction projects by encouraging competition among contractors and subcontractors—and it gives firms the flexibility to build teams based on skills rather than union affiliation.

Armcorp’s hiring and training practices align with ABC Ohio Valley’s workforce development and apprenticeship vision. Apprenticeship programs in the construction sector provide hands-on training and education, allowing individuals to learn a trade while earning a wage. Many construction companies offer full-time, paid training programs that allow individuals to learn trades while working, such as becoming a journeyman electrician or carpenter. Training programs for construction professionals often include apprenticeships, which provide hands-on experience and mentorship from skilled tradespeople.

The firm invests in safety programs, ongoing skills training, including OSHA 10 and OSHA 30 certifications, and internal mentorship that develops field technicians into superintendents. Construction safety programs are essential for reducing workplace injuries and fatalities, with the Occupational Safety and Health Administration (OSHA) reporting that effective safety programs can reduce injury rates by 20-40%. The National Safety Council emphasizes that construction companies with strong safety cultures not only protect their workers but also improve productivity and reduce costs associated with accidents and injuries.

Armcorp’s veteran-focused identity creates additional pathways into the workforce. By supporting initiatives like Lots for Soldiers and actively recruiting veterans into trades roles, they tap into a population that brings discipline, teamwork, and mission focus to the jobsite. Internal retention rates run higher when employees see that their employer invests in both their careers and their communities.

How Armcorp Embodies ABC Ohio Valley’s Six Pillars

ABC Ohio Valley’s Six Pillars framework—Workforce Development, Training, Safety, Communication, Marketing, and Advocacy—provides a structure for how member firms can grow their businesses while strengthening the merit shop community. Armcorp Construction gives those pillars a face and a track record the chapter can point to.

Workforce Development: Armcorp’s emphasis on developing field leaders, providing opportunities for craft professionals to advance, and supporting veterans into skilled roles aligns directly with this pillar. Their partnership with Lots for Soldiers and internal mentorship programs creates pathways that address the 60,000-worker shortage.

Training: Professional development in the construction industry can enhance skills in project management, safety protocols, and technical expertise, which are critical for career advancement. Armcorp’s investment in OSHA certifications, ABC apprenticeships, and on-the-job training ensures its team continues developing throughout their careers.

Safety: On projects such as the Dayton VA Medical Center Dock Replacement, Armcorp’s safety culture is evident in job hazard analyses, pre-task planning, and coordination with the owner’s safety teams. Their incident rates are below industry averages, demonstrating that safety isn’t a checkbox—it’s embedded in how they work.

Communication: Transparent interactions with owners, weekly VA huddles for complex projects, and internal communication that connects field and office teams characterize Armcorp’s approach. Clients see a contractor who keeps them informed rather than surprises them.

Marketing: Armcorp’s presence in community and chamber activities—from the Celina-Mercer County Chamber banquet to the Mercer County Fairgrounds—builds reputation alongside revenue. Their community engagement is marketing in its truest sense: demonstrating values through action.

Advocacy: Trade associations like ABC Ohio Valley play a crucial role in representing the interests of merit-shop contractors at local, state, and national levels. Armcorp’s membership and project success stories strengthen ABC’s voice when engaging policymakers on issues affecting merit shop contractors. Advocacy efforts in the construction industry often focus on legislative updates that impact regulations, safety standards, and funding for infrastructure projects. Legislative advocacy in the construction industry can lead to changes in policies that affect labor laws, environmental regulations, and public funding for construction projects.
