Structural Calculations & Reports for DC, Maryland & Virginia
If you need structural calculations for a permit, an assessment report for a property transaction, or engineering documentation for insurance — BOZ Engineering Group delivers PE-stamped structural calculations and reports on a fast turnaround, formatted for the specific jurisdiction where you're submitting. We produce beam calcs, lateral analyses, full calculation packages, structural assessment reports, and feasibility studies for residential and commercial projects throughout Washington DC, Maryland, and Virginia. Every deliverable is prepared with the plan reviewer in mind — because a calculation that's technically correct but formatted wrong still gets kicked back.
Who This Is For
Contractors needing structural calcs for permit — You have a project ready to submit and the jurisdiction requires PE-stamped structural calculations. You need them fast, accurate, and formatted so the plan reviewer doesn't send them back.
Architects needing structural verification — You've designed a space and need a structural engineer to verify your framing, size your beams, and produce the calculations your client's permit application requires.
Building owners needing structural assessments — You have an existing building and need a licensed PE to evaluate its structural condition — for a sale, a refinance, a change of use, or because something doesn't look right.
Insurance companies needing structural reports — You need a PE-stamped structural assessment documenting storm damage, structural deficiencies, or building condition for a claim or underwriting decision.
Property buyers needing pre-purchase evaluations — Your inspector flagged structural concerns and you need a licensed engineer to assess the building before you close the deal.
Need structural calcs or a report on a tight timeline? Call us at +1 202-998-5445 — we'll give you a turnaround estimate on the first call.
Why Jurisdiction-Specific Structural Calculations Matter
Structural calculations aren't just math — they're a communication tool between your engineer and the plan reviewer who decides whether your permit gets approved. Every jurisdiction in the DC, Maryland, and Virginia region has different expectations for how calculations are organized, what code references are cited, what load combinations are shown, and how results are presented. A calculation package that sails through Fairfax County may get comment letters in Arlington or DC.
This is where generic calculation templates and out-of-state engineers cost you time and money. Incomplete calculations get kicked back with reviewer comments. Calculations that don't reference the correct local amendments get flagged. Assessment reports without a PE stamp carry no legal weight for insurance claims, property transactions, or code compliance. Every round of revisions adds weeks to your timeline and frustration to your project.
BOZ Engineering Group submits structural calculations and reports to DC, Maryland, and Virginia jurisdictions every week. We know what each reviewer expects to see, how they want it organized, and what triggers comment letters. Your calculations are technically sound and strategically formatted — which means fewer review cycles, faster permits, and documentation that holds up when it matters.

Our Structural Calculations Process
Step 1: Scope Definition
We review your project — architectural plans, permit requirements, or assessment needs — and define exactly what calculations or reports are required. We confirm the jurisdiction, the submission format, and your deadline so there are no surprises.
Step 2: Document Review & Site Visit (If Needed)
For calculation packages, we review your architectural drawings, surveys, and any existing structural information. For assessment reports, we schedule a site visit to visually inspect and document the structural conditions firsthand.
Step 3: Engineering Analysis
Our PE performs the structural analysis — gravity loads, lateral loads, member sizing, connection design, and load path verification. For assessment reports, we document conditions, identify deficiencies, and develop recommendations. Everything is referenced to the applicable building code and local amendments.
Step 4: Calculation Package or Report Production
We compile the calculations or report into a clean, organized, PE-stamped document formatted for the specific jurisdiction or intended use. Calculation packages include summary sheets for quick reviewer reference. Assessment reports include photos, findings, and recommendations.
Step 5: Delivery & Support
We deliver the stamped package and support you through the review process. If the plan reviewer issues comments, we respond with revisions. For assessment reports, we're available to discuss findings with property owners, buyers, insurance adjusters, or attorneys as needed.
What Your Structural Calculations Package Includes
Gravity load analysis (dead loads, live loads, snow loads per local code)
Lateral load analysis (wind and seismic per jurisdiction requirements)
Individual member design — beams, columns, headers, joists, bearing walls
Connection design and detailing where required
Load path narrative from roof to foundation
Code references specific to your jurisdiction (IBC, IRC, local amendments)
PE stamp and signature on all calculation sheets
Formatted for your specific plan reviewer and jurisdiction
Summary sheets for quick reviewer reference
Revision response if plan reviewer issues comments

Frequently Asked Questions
Structural Engineering Questions — Answered by Our Team
Wondering what structural calculations cost, how fast we can deliver, or whether you need a full calculation package or just a single beam calc? Here's what contractors, architects, and property owners across the DMV ask most.
How much do structural calculations cost?
Structural calculation fees depend on whether you need individual member calculations or a full calculation package, as well as the project size and complexity. Assessment reports are scoped separately. We provide a fixed quote before starting any work — call +1 202-998-5445 or fill out the form on this page.
How fast can you deliver structural calculations?
Simple individual calculations (beam sizing, header calcs) take 3 to 7 business days. Full calculation packages for new construction or major renovations take 2 to 4 weeks. Rush turnaround is available for an additional fee — call us to discuss your deadline.
Do I need a full calculation package, or just individual calcs?
It depends on the jurisdiction and the scope of work. Many wall removals and simple modifications only require individual beam/column calculations. New construction, additions, and major renovations typically require a full calculation package with gravity and lateral analysis. We'll tell you exactly what your project and jurisdiction require.
Why do my calculations keep getting kicked back by the plan reviewer?
The most common reasons are incomplete load paths, missing lateral analysis, incorrect code references, and formatting that doesn't match what the jurisdiction expects. BOZ formats every calculation package for the specific jurisdiction where you're submitting — DC, Fairfax County, Arlington, Montgomery County — because each one has different expectations.
Do structural assessment reports need a PE stamp?
For the report to carry legal weight — for insurance claims, property transactions, code compliance, or litigation — yes, it needs a PE stamp. An assessment report without a PE stamp is essentially an opinion. A PE-stamped report is a professional engineering document backed by a licensed engineer's credentials and liability.
Can you help if the plan reviewer issues comments on my calculations?
Yes. Comment response is included in our scope. When a plan reviewer issues comments, we review them, update the calculations, and resubmit. Our goal is to get your permit approved — not just hand you a document and disappear.
What's the difference between structural calculations and a structural report?
Structural calculations are the engineering math — load analysis, member sizing, connection design — produced to support a design for permit. A structural report is a condition assessment of an existing building, documenting what we observe, what's deficient, and what we recommend. Different deliverables for different purposes.
What jurisdictions do you serve?
BOZ is licensed in DC, Maryland, Virginia, and Florida. We regularly submit structural calculations to Washington DC DCRA, Fairfax County, Arlington County, City of Alexandria, Montgomery County, Prince George's County, and jurisdictions throughout the DMV. In Florida, we serve Tampa, Miami, Fort Lauderdale, Orlando, and more.
