What San Engineering LLC does

San Engineering LLC is a privately held, minority-owned civil and structural engineering firm headquartered in Denver, Colorado, with a primary office in Littleton. The company was founded by Eduardo San Rubio, PE (Managing Member, Principal, and Civil Engineering Manager) and John Migliaccio, PE (Group Manager, Structural Engineering Services, Partner), and operates with a small team of seven employees delivering multidisciplinary infrastructure design services across Colorado and the broader Rocky Mountain region.

The firm provides twelve distinct engineering service lines, including civil and structural engineering, bridge engineering, transportation and roadway design, rail engineering, airport and aviation engineering, drainage and water systems, site development, parks and trails, inspection services, design/build, and utility design and coordination. Underlying technology consists of industry-standard engineering software — SAP2000, LEAP Bridge Suite, AASHTOWare BrR, and L-Pile for structural analysis; Civil 3D, Inroads, and Revit Structural for 3-D modeling — rather than proprietary platforms. The firm holds six public-sector certifications (CDOT DBE, CDOT ESB, CDOT SBE, CDOT Pre-Qualified, RTD SBE, and City and County of Denver MBE) plus LEED-accredited design staff, and applies these credentials to compete on set-aside and diversity-goal contracts.

The business model is project-based professional services: revenue is generated through consulting fees on civil and structural engineering design, inspection, and coordination projects valued up to $20 million, delivered either as a prime consultant directly to public agencies or as a strategic sub-consultant to general contractors and prime engineering firms. Customers are concentrated in Colorado government (CDOT, RTD, City and County of Denver, Denver International Airport, Denver Public Schools) with adjacent enterprise work for Class I freight railroads (BNSF, Union Pacific). Go-to-market is relationship-driven enterprise field sales, supported by a content website and social media presence; the company is privately held with no disclosed funding rounds, parent entity, or revenue figures.

Broad incumbents

• AECOM: Global infrastructure consulting firm with major Colorado transportation, aviation, and rail practices serving CDOT, RTD, and DIA — large incumbent that can prime the same pursuits where San Engineering serves as sub-consultant.
• Stantec: Global engineering and design consultancy with significant Colorado transportation, water, and infrastructure practices serving CDOT, RTD, and municipal clients — broader portfolio competitor for the same public-sector RFPs.
• WSP: Global professional-services firm with extensive U.S. transportation and infrastructure footprint actively bidding CDOT, RTD, and DIA work — a large-scale incumbent whose Colorado projects often tap sub-consultants like San Engineering.
• HDR Inc. Employee-owned engineering and architecture firm with one of the largest U.S. transportation practices and significant Colorado presence pursuing CDOT and rail programs — broader incumbent competing for similar public infrastructure work.
• Michael Baker International: Large national engineering, planning, and consulting firm with a strong Colorado transportation practice — competes with San Engineering on CDOT and DOT pursuits but operates at materially greater scale and capability breadth.
• Burns & McDonnell: Employee-owned engineering firm with strong U.S. transportation, rail (including RTD), aviation, and water practices — comparable in serving Colorado public agencies but at much greater scale across the full project life cycle.

Direct peers

• CTL Thompson: Denver-based engineering firm offering geotechnical, structural, and construction-materials services to Colorado public agencies and developers — adjacent Colorado specialty peer serving overlapping CDOT/RTD programs.
• Martin/Martin: Lakewood, Colorado-based civil and structural engineering consulting firm serving public agencies, transportation, and development clients across the Rocky Mountain region — directly comparable in size, geography, and service mix to San Engineering.
• KL&A Engineers: Structural and civil engineering firm headquartered in Wyoming/Colorado serving transportation, municipal, and private development clients — comparable specialty boutique with similar public-agency focus and project sizes.
• JVA Consulting Engineers: Colorado-based civil, structural, and environmental consulting firm with deep public-sector and infrastructure practice — comparable mid-size regional peer competing for the same CDOT/RTD work.
