What Global Engineering Solutions does

Global Engineering Solutions, now operating as Salas O'Brien of Washington DC, is a Washington, DC-based engineering, program management, and construction management firm founded in 2008. The firm serves public and private clients in the DC Metro area across vertical markets including government/public sector, healthcare, science and technology, education, and commercial real estate, with a specific specialization in Net-Zero design for buildings and infrastructure. It was previously known as Global Engineering Solutions of Washington DC before being renamed to Salas O'Brien of Washington DC, marking its integration into the broader Salas O'Brien engineering network. The firm lists Laleh Zargarinejad as President and Owner.

Service delivery is organized around four offerings: Engineering Services (design and consulting), Program Management (multi-project portfolio oversight), Construction Management (build-phase coordination), and Net-Zero Design (specialized sustainable design for buildings and infrastructure). The website navigation also surfaces an Energy service line. A single source of revenue is professional services fees billed on a project basis, generated through long-term enterprise engagements and competitive public-sector bids rather than productized or subscription pricing. Public sector work is anchored by engagements such as DC Water's Biosolids Management Program Main Process Train engineering design and design-build services for DC Department of General Services projects including McKinley Technology High School (STEM Middle School) and Duke Ellington School of the Arts; private/nonprofit engagements include the AARP Renovation project in Washington DC.

Distribution is direct enterprise sales to government agencies and private organizations in the DC Metro area, with a website/portfolio page serving as the primary marketing surface. Pricing is not publicly disclosed and is scoped per engagement. The firm has a small headcount of 11-50 employees, no disclosed funding rounds, no parent company or PE/VC backers identified in the source data, and no public listing or stock exchange presence. Information on certifications, compliance, management team beyond the President, and detailed financial metrics is absent from the available data.
