Structural Engineering Services in Washington DC, Maryland & Virginia

Licensed Professional Engineers delivering stamped structural plans for residential and commercial projects across the DMV. From load-bearing wall removals to full new construction packages — we design it, we stamp it, we get it approved.

Residential & Commercial Structural Design

PE-stamped structural plans for homes, renovations, and commercial builds — ready for permit submission the day you receive them. From single-family additions to multi-story developments, one in-house team handles it all.

Load-Bearing Wall Analysis & Removal

We analyze your framing, design the beam and post details, and deliver stamped plans your contractor can build from and your jurisdiction will approve. Most load-bearing wall projects are turned around within 5 to 10 business days from site visit.

Foundation Design & Repair

We design new foundations based on actual soil conditions and engineer repair solutions for foundations showing settlement, cracking, or failure. Our in-house geotechnical team can test your site first — so your foundation is built on real data, not assumptions.

Structural Calculations & Reports

Stamped engineering calculations for beams, columns, connections, and load paths — delivered as a report your plan reviewer can approve on the spot. We also prepare structural assessments for existing buildings, renovation feasibility, and pre-purchase evaluations.

Additions, Alterations & New Construction

Every addition, second story, garage conversion, or new build needs a full structural package before a permit office will look at it. We handle the complete scope from site visit through approved permit, coordinated with your architect or designer.

Retaining Wall Design

We design retaining walls engineered for actual soil pressure, drainage, slope conditions, and surcharge loads — not guesswork. Every design includes full structural details, material specs, drainage provisions, and stamped calculations ready for permit.

Roof Truss & Framing Design

We design roof truss layouts and framing systems engineered for the snow loads, wind uplift, and code requirements specific to your jurisdiction. Our plans include member sizing, connection details, and full coordination with truss manufacturers when prefab is specified.

Building Code Compliance Review

We review your drawings against IBC, IRC, and local amendments before you submit — catching the issues that generate comments or rejection. We also prepare stamped code compliance reports for change of use, occupancy reclassification, and renovation projects.

Why DMV Property Owners Choose BOZ Engineering

Every delayed permit and every round of revision comments costs you time and money. Our structural engineering team designs with the approval process in mind from day one. We know what DC, Maryland, and Virginia plan reviewers look for because we submit to them every week. Your plans are detailed, code-compliant, and built to move through review — not sit in a queue collecting comments.

Most Clients Pair Structural With MEP and Permitting

85% of our clients need more than structural plans. They need MEP coordination, civil site plans, or someone to pull the permit and manage the review process. We provide all of it under one contract — so your project stays on one timeline with one point of contact.
