The firm's core service offering is MEP engineering design, with BIM coordination, base-building infrastructure design, and LEED certification design as adjacent capabilities.

Project examples include LEED certified mixed-use developments, hotel renovations, corporate headquarters with amenity spaces, indoor arenas, cultivation and extraction laboratories, and medical office fitouts. Revenue is generated on a project-based, quote-by-quote professional services model, with pricing negotiated per project scope. DDG has no disclosed external investors, no parent company, no partnerships, and no technology products beyond standard BIM tooling. Go-to-market is direct enterprise sales to developers, property owners, corporations, and general contractors, supported by a portfolio-based company website.

Broad incumbents

• Stantec: Stantec is a global engineering, architecture, and environmental services firm with a strong buildings practice and track record of acquiring niche MEP firms (e.g., ESD). It is a relevant incumbent comparable and a likely strategic acquirer profile for DDG.
• AECOM: AECOM is one of the largest global engineering and infrastructure consulting firms with a substantial buildings design practice. It is a broad incumbent comparable on end markets and scope, though at vastly different scale and delivery model.
• WSP Global: WSP is a global professional services firm with a large Buildings practice delivering MEP, structural, and sustainability design at scale. It competes with DDG for the same enterprise clients but with a much broader portfolio and deeper bench.
• Burns & McDonnell: Burns & McDonnell is a large U.S. engineering, construction, and consulting firm with growing facilities and MEP design capabilities. It is a broad incumbent peer that competes with DDG on complex commercial and industrial facility projects.
• Jacobs Solutions: Jacobs is a global engineering services firm with significant buildings and infrastructure design capability. It is a broad incumbent peer that DDG may compete against as a subconsultant or on larger enterprise pursuits.

Direct peers

• IMEG Corp: IMEG is a U.S. engineering firm delivering MEP, structural, and technology design for healthcare, higher education, commercial, and government clients. It is a direct peer to DDG in terms of services (MEP/BIM/LEED design) and customer segments, though at significantly larger scale.
• Affiliated Engineers: Affiliated Engineers (AEI) is a national MEP consulting engineering firm focused on complex, high-performance buildings including labs, healthcare, and higher-ed. Like DDG, AEI is a specialist MEP house (not a multi-discipline generalist) that wins on technical depth, which makes it the most direct comparable for DDG's positioning.
• ME Engineers: ME Engineers is a specialized MEP/FP and technology systems design firm serving entertainment, cultural, sports, and high-end commercial projects. DDG's arena and corporate headquarters work closely mirrors ME Engineers' portfolio, making it a direct peer in the boutique high-performance MEP space.
• Page (PageSouthwell): Page is a multidisciplinary engineering and design firm with strong MEP and architectural practices serving commercial, healthcare, and industrial clients. Its project types and consulting-only engineering model overlap directly with DDG's offerings.

Emerging players

• ESD (now part of Stantec): ESD was a Chicago-based MEP/technology systems consulting firm with strong local market presence and similar mix of workplace, mission-critical, and healthcare design. It is highly comparable to DDG in geography and service mix, illustrating both the opportunity and the consolidation path (acquired by Stantec).
