DeepBlue Engineering is a specialized bridge and structural engineering consulting firm serving Louisiana, Mississippi, and Texas. Senior-led, end-to-end, and built to function as a seamless extension of your team.
DeepBlue Engineering, LLC was founded by Maggie Ye, PE — a licensed engineer with 10+ years of experience and 400+ bridges designed, rated, and inspected across Louisiana, Mississippi, and Texas. The firm was built to solve a persistent problem in the DOT and structural consulting market: workload spikes, tight deadlines, and rework caused by inconsistent subconsultant quality.
DeepBlue fills that gap by delivering submission-ready work with minimal oversight, functioning as a seamless, high-reliability extension of client teams — whether that's a prime consultant managing a DOT contract, a municipality replacing a local structure, or a contractor needing construction-phase engineering support.
We operate as a lean, senior-led practice: every project is handled directly by an experienced, licensed engineer — not passed down to junior staff — so quality and reliability stay consistent from proposal to final stamped plans.
From concept through submission-ready plans — design, drafting, load rating, and inspection across all bridge and structural types, without relying on outside support.
A team of licensed PEs with deep hands-on experience — every deliverable is reviewed and stamped by the engineer who did the work.
Active experience and agency relationships across LaDOTD, MDOT/OSARC, and TxDOT project delivery requirements.
Low overhead means competitive rates without compromising the quality of the person doing the work — and faster turnaround than larger firms.
From bridge inspection and load rating to general structural design and construction-phase support, DeepBlue covers the full lifecycle of a structure.
Inspection, load rating, design, and rehabilitation across all bridge types — prestressed concrete, steel, truss, arch, box culvert, and slab spans.
Beyond bridges — structural design for site, roadway, and civil infrastructure applications.
Engineering support that carries a project through construction, not just to bid.
A sample of inspection, load rating, and design work delivered for state DOTs, municipalities, and prime consultants.
Inspected and authored hundreds of inspection reports statewide; load rated bridges using BrR and ConSpan; developed load rating templates and procedures.
Three bridge plan sets — two 300-ft prestressed concrete FIB bridges and one skewed steel plate girder bridge (280+358+280 ft) — produced using OpenBridge Modeler.
Inspected and developed repair plans for a damaged 550-ft, three-span steel through-truss bridge; post-design construction monitoring and shop drawing review.
320-ft bridge plans delivered on an accelerated six-month schedule; structural design calculations, plan production, and construction-phase technical support.
Detailed inspections and load ratings for four steel through-truss bridges; built truss models in BrR and developed truss load rating procedures.
Bridge plan development with complex geometry and superelevation; pile foundation design and structural analysis; construction coordination and support.
Load rating for complex bridges; hand calculations for truss members, floor beams, and hammerhead bents; strut-and-tie modeling for substructure evaluation.
Multiple design packages including LG and LU girders, slab spans, substructure, foundations, and I-10 repair plans; shop drawing review and RFI response.
Every project at DeepBlue is handled by an experienced, credentialed engineer — not a junior team working in the background.
10+ years of experience with 400+ bridges designed, rated, and inspected across Louisiana, Mississippi, and Texas. End-to-end capability — able to take a bridge or structure from concept to submission-ready independently, across all bridge and structural types.
Experienced bridge and geotechnical engineer with a background at SDR Engineering and LaDOTD's bridge design and geotechnical teams. Brings deep expertise in pile design and bridge structural analysis.
Bridge engineer specializing in inspection, load testing, and load rating. Certified NHI Team Leader with hands-on experience inspecting truss bridges and a strong design foundation from SDR Engineering.
