What Clemens Construction does
Clemens Construction Company, Inc. is a privately held, full-service commercial general contractor and construction manager headquartered at the Drexel Building in Center City Philadelphia, founded in 1979 by Jim Clemens. The firm operates a horizontal-segment business across multifamily, hospitality, historic preservation, education, health sciences, corporate, retail, special projects, and social-impact construction, primarily in the Philadelphia metropolitan area with select multi-state institutional work (notably a PNC Bank branch rollout across DE, KY, NJ, OH, and VA). The technical core of the firm is its self-performing carpentry and millwork division — the 4th largest carpentry contractor in Philadelphia with 350+ union carpenters and an in-house millshop — supported by BIM-based constructability analysis and a design-assist delivery model. The company also maintains company-wide LEED accreditation and reports more than 60 LEED-certified projects completed.
Clemens' project portfolio skews to complex, schedule-sensitive, occupied-environment work: marquee projects include the $30M Cristo Rey Philadelphia High School on a former brownfield, the Four Seasons Hotel Philadelphia Sky Garden Suites fit-out on Level 45 of the Comcast Technology Center, the Union League Trumbauer's Rooftop Restaurant, the adaptive-reuse UPenn College Hall West Wing, and conversions of landmark hotels such as the Sheraton Society Hill-to-Philadelphia Marriott Old City. Repeat clients include Hersha Hospitality Trust ($10M across Rittenhouse and Westin over five years), Loews Hotel (eight years including a 26-story guest-room refresh), the Union League of Philadelphia, and the University of Pennsylvania. Pricing is project-specific via RFQ/RFP under Vice President of Preconstruction Paul Horning, with no published rate card; project values disclosed in testimonials range from $7.6M (Boyds Philadelphia) to $30M (Cristo Rey).
The operating profile reflects a regional GC scale with substantial self-perform labor: 51-100 office staff, 350+ carpenters, eight served market segments, and proven execution across ground-up, renovation, and adaptive-reuse modalities. Differentiators cited in awards and client testimony include occupied-environment expertise, in-house millwork control, LEED specialization, and a safety record of 500,000+ consecutive hours without an incident (recognized by GBCA). Leadership comprises Founder Jim Clemens, President Steve Pouppirt, CFO Brent Paxton, VP Preconstruction Paul Horning, HR Director Kimura Anderson, and Operations Manager (Millwork) Joe Bellenzeni. The firm owns no subsidiaries, has no disclosed parent company or outside investors, and operates without a public listing.
