Berghammer Construction Corporation

What Berghammer Construction Corporation does

Berghammer Construction Corporation is a privately held general contractor founded in 1928 by Edward P. Berghammer and headquartered in Butler, Wisconsin. The firm provides preconstruction, construction management, design-build, self-perform, and a dedicated Special Projects Division to enterprise and institutional clients across ten market verticals - healthcare, education, industrial and manufacturing, senior living, multi-family and mixed-use, hospitality and retail, religious, corporate, civic, and special projects - operating exclusively in southeastern Wisconsin. Notable technical components include in-house concrete, carpentry, and selective demolition crews (described as one of the largest pre-cast wall panel project builders in Wisconsin), supplemented by Matterport 3D scanning, drone-based site capture, BIM, and cloud-based project management systems. The current principal ownership group comprises Kevin White (President), Matt Iwanski (Executive Vice President), Tiffany May (Vice President, Preconstruction), Martin Chapa (Vice President, Healthcare Construction), and James F. Parks (Principal, retired January 2026); the firm is governed by Wisconsin law and has historically been family-led, transitioning to professional management after the 1988 trade-name sale and 2017 ownership restructuring.

The business model is project-based commercial construction: revenue is earned on a one-time contract basis via general contracting, professional services (construction management and self-perform labor), or design-build delivery, with each engagement custom-priced based on scope, specifications, and requirements and documented in formal multi-year contracts. Go-to-market is direct enterprise field sales through RFP/RFQ processes and long-term relationship referrals, anchored by 20+ year client relationships with Charter Communications, Seeds of Health, Lumen Christi Parish, Azura Memory Care, Aurora Health Care, Briggs & Stratton, and other regional enterprises. No public revenue, EBITDA, or backlog disclosures are made; the company self-describes as a "multi-million-dollar firm" with nearly 100 employees, headquarters of 15,000 SF constructed in 1995, and a community foundation (established 2009) that has supported more than 100 local organizations.

The company's value proposition rests on principal-led project execution ("The Berghammer Way"), self-perform trade capability for schedule, safety, and quality control, modern visualization and modeling tools, and a track record of multi-decade client retention; competitive positioning emphasizes hands-on ownership involvement, transparent process, and demonstrated safety (multiple AGC Leadership in Safety Awards across 2018-2025). Pricing is bespoke and not publicly disclosed. The firm maintains a marketing presence via berghammer.com and a dedicated plan room (berghammerplanroom.com) for subcontractor engagement, with earned media through industry awards (Mayor's Design Award, Daily Reporter Top Projects, Milwaukee Business Journal Real Estate Awards).
