DEMS

What DEMS does

DEMS LLC (Dominion Engineering Management Services), founded in 2002 and headquartered in Houston, Texas, is a privately held professional services firm that delivers engineering, construction management, procurement, program management, and technology consulting across complex capital projects. The company operates through four divisions - DEMS Engineering, DEMS Construction, DEMS Infrastructure & Maintenance, and DEMS Covenant Foundation - and serves clients in oil and gas, petroleum refining and petrochemical, power and renewable energy, infrastructure and transportation, residential and commercial building, and carbon capture (CCUS) sectors in the United States and internationally.

The firm's core service stack spans turnkey EPCI delivery, advanced work packaging (AWP) and sub-contracting management, 3D scanning, value engineering, LEED-certified project scheduling, and Portfolio Management Office (PMO) solutions with an explicit ESG/sustainability lens. A newer offering, Digital Transformation as a Service (DTaaS), bundles cloud computing, data analytics, AI/ML, IoT, and digital twin technology across the asset lifecycle, including predictive maintenance and energy forecasting. Adjacent revenue lines include local heavy equipment rental in the Houston/Montgomery County area and the Project Management Academy, which runs cohort-based training (including AWS, Azure, and Google Cloud certifications) in partnership with TenStep Inc. and PMI Houston targeting ESG Renewable Project Management credentials.

Commercially, DEMS is sales-led with direct enterprise engagement via website, phone, and email, and reaches the U.S. PM community through its PMI Houston channel. Pricing is predominantly quote-based across consulting, construction management, and technology services; equipment rentals are priced publicly by duration, and training programs operate on fixed per-seat terms with tiered cancellation policies. The firm claims over 150 years of combined industry experience across its consultants, engineers, and project managers, reports a 15% reduction in client capital expenditures attributable to its digital-deployment approach, and has named ExxonMobil and Halliburton as testimonial clients for its training services. No ownership, funding, or revenue disclosures are available in the source material.
