What D'Leon Consulting Engineers does

D'Leon Consulting Engineers (DLCE) is a privately held civil engineering and Program/Construction Management (PMCM) consulting firm headquartered in Long Beach, California, founded in 1987 by Domingo Leon and now led by Borja Leon, PE. The firm provides planning, engineering design, program management, and construction management support services for transportation and infrastructure projects in aviation, rail and transit, streets and highways, water and utilities, serving public-sector agencies primarily through competitive contracting and master service agreements. Its customer roster includes Los Angeles World Airports (LAWA), LA Metro, Caltrans, the Port of Long Beach, the Orange County Transportation Authority, Sacramento County Department of Airports, JFK Airport, Phoenix Sky Harbor, the City of Inglewood, and the California High-Speed Rail Authority.

DLCE works as both a prime contractor and sub-consultant on multi-billion-dollar capital programs, including the LAWA Capital Improvement Program at LAX, Crenshaw/LAX and Purple Line light-rail extensions, the I-405 Improvements, and design/build support to prime designers such as HNTB. Technical capability centers on civil engineering design (trackwork, roadway, drainage, structural, utility coordination) augmented by Building Information Modeling (BIM) and digital workflows through Autodesk Construction Cloud, with a dedicated BIM Administrator / Technology Innovation Developer role deployed on LAWA engagements. Certifications held include Small Business Enterprise (SBE), Minority-Owned Business Enterprise (MBE) — including through the Port Authority of New York and New Jersey — and Disadvantaged Business Enterprise (DBE), which provide preferential access to diversity-targeted procurements.

The firm's go-to-market is enterprise field sales to government agencies through competitive bids, with marketing conducted primarily via its company website, LinkedIn presence, and participation in project milestones and industry events. DLCE operates from five U.S. offices (Long Beach, CA; Seattle, WA; Houston, TX; Las Vegas, NV; and presence in NY/NJ), generates revenue through professional services contracts (typically multi-year, fixed-price or cost-reimbursable), and is privately held with no institutional or private-equity ownership disclosed.
