Blackline

What Blackline does

Blackline Corporation is a privately held general contractor and construction management firm headquartered in Gulfport, Mississippi. The company delivers projects across three core service lines — Construction Management at Risk, Design-Build, and traditional General Contracting — with a vertical focus on healthcare facility construction (particularly renal dialysis clinics for Fresenius Kidney Care), historical restoration (anchored by the Saenger Theatre in Biloxi), and commercial design-build. Blackline holds contractor licensure in 19 U.S. states plus Puerto Rico and operates an 11–50 person organization executing project values that range from approximately $500K for smaller dialysis clinics to over $23M for landmark restoration work.

The business model is project-based and one-time in nature: revenue is generated through competitive bids and direct contract negotiations with healthcare operators, real-estate developers, and public/institutional owners. Go-to-market relies on referral relationships with architecture and engineering firms (Eley Guild Hardy, Dale Partners, LPK, Hardy & Associates, Oman-Gibson, Machado | Patano) and direct relationships with healthcare end-clients, primarily Fresenius Kidney Care. Marketing is minimal — a project-portfolio website, a LinkedIn presence, and referral-letter testimonials — with no paid acquisition or digital channel evident.

Operationally, Blackline differentiates on craftsmanship, schedule discipline (multiple dialysis projects delivered in 105–150 days), and safety record (zero recordable incidents cited on multiple projects). Leadership is anchored by Project Manager Kempton Batia and Superintendent Josh Swinford, both repeatedly named in client referrals. The company carries no disclosed debt or equity funding, no AI/ML capability, and no proprietary technology beyond standard construction project management systems; competitive advantage is rooted in reputation, multi-state licensure, and repeat-customer trust rather than technology or scale.

Direct peers

• DPR Construction: DPR is a national commercial GC with strong healthcare and life-sciences verticals, executing technically complex medical and ambulatory surgery projects. It is comparable to Blackline in targeting regulated healthcare facility work, but at a meaningfully larger scale and with deeper technical resources.
• McCarthy Building Companies: McCarthy is one of the largest U.S. healthcare-specialized general contractors, with deep hospital, ambulatory, and medical office building portfolios and significant self-perform capability. It represents the scaled version of the healthcare-specialist model Blackline is pursuing, and competes for the same dialysis and outpatient clinic clients.
• Hoar Construction: Hoar Construction is a privately held Southeast-focused general contractor with healthcare, higher education, and commercial experience. It shares Blackline's regional delivery model, healthcare vertical focus, and privately held ownership structure, and operates in overlapping Gulf South markets.
• Gilbane Building Company: Gilbane is a large, family-owned U.S. general contractor with a dedicated healthcare and education practice and regional offices across the country. Its mix of healthcare construction, education, and historic/civic work overlaps meaningfully with Blackline's verticals, and its regional delivery model parallels Blackline's licensed-state footprint approach.
• Robins & Morton: Robins & Morton is a privately held U.S. general contractor with a nationally recognized healthcare construction practice, including extensive hospital and outpatient facility experience. It is the most direct comparable to Blackline in terms of healthcare-construction specialization, regional-to-national scaling path, and middle-market project size profile.

Broad incumbents

• Clark Construction Group: Clark Construction is a major U.S. general contractor with healthcare, education, and public-sector work across multiple states. It is comparable to Blackline as a privately oriented contractor with healthcare experience, but operates with significantly larger project size capacity and national reach.
• Manhattan Construction Group: Manhattan Construction is a diversified U.S. general contractor with healthcare, education, sports, and public-sector work. It is comparable to Blackline in healthcare and historic construction delivery, but operates at substantially larger scale and serves national accounts.
• Skanska USA: Skanska is a global construction firm with a sizable U.S. healthcare and civil practice, competing for large hospital and outpatient projects. It is comparable to Blackline in healthcare construction capability but operates at much greater scale, geographic breadth, and balance-sheet capacity.
• Turner Construction Company: Turner is one of the largest U.S. general contractors with a national healthcare practice that competes for major hospital systems and outpatient programs. It is comparable to Blackline in healthcare facility delivery but operates at a scale that lets it absorb GMP risk and execute national account programs Blackline cannot match.
• Brasfield & Gorrie: Brasfield & Gorrie is one of the largest privately held U.S. general contractors with significant healthcare, commercial, and institutional work in the Southeast — Blackline's core geography. It competes for the same healthcare systems and dialysis operators across the Gulf South region but at a larger scale and with broader service lines.
