What Our Structural Engineering Service Includes
Every structural package is designed, checked and sealed by a professional engineer licensed in the state where the project is permitted.
Framing Design & Structural Analysis
Complete gravity and lateral framing layouts for wood, cold-formed steel, structural steel and concrete — joists, rafters, beams, headers, columns, shear walls and diaphragms sized and detailed.
Load Calculations
Dead, live, roof live, wind, seismic and snow loads derived per ASCE 7 and your jurisdiction’s adopted edition, with the full calculation package sealed and submitted alongside the drawings.
Foundations & Footings
Spread footings, strip footings, grade beams, mat and post-tensioned slabs, pier and helical systems — sized against the geotechnical report or presumptive bearing values where no report exists.
Retaining & Basement Walls
Cantilever, restrained and segmental retaining walls checked for overturning, sliding and bearing, with surcharge, drainage and global stability addressed.
Structural Drawings & Details
Permit-ready plans, sections, schedules and connection details drawn so a framer can build from them and a plan reviewer can approve them without a correction letter.
Assessments & Engineer Letters
Existing-condition assessments, load-bearing wall removal letters, deck and balcony evaluations and repair recommendations, sealed for submittal to the building department or an HOA.
What Arrives in Your Structural Package
You are quoted against a written deliverable list before any work starts, so there is never a question about which sheets and calculations you are paying for.
- Sealed foundation plan with footing schedule and reinforcement details
- Floor and roof framing plans with member sizes, spans and spacing
- Lateral system plan — shear walls, hold-downs, braced lines and diaphragm details
- Structural sections, connection details and typical construction notes
- Full load calculation package: gravity, wind, seismic and snow per ASCE 7
- Foundation bearing check against the geotechnical report or code presumptive values
- General structural notes covering materials, testing and special inspections
- Professional Engineer seal and signature valid in your project’s state
Structural Support Built Around Your Role
Architects & Designers
Structural sheets that coordinate cleanly with your architectural set — matching grids, datums and sheet conventions, so redlines do not bounce back between disciplines.
Contractors & Builders
Buildable drawings with the member sizes, connections and details your framers and subs need to price the work accurately and build it right the first time.
Developers & Project Owners
Certified structural documentation for residential, commercial and mixed-use developments, delivered on a schedule that matches your permitting timeline.
Homeowners & Renovators
Load-bearing wall removals, additions, deck and balcony evaluations and foundation repairs — explained in plain language and sealed for your permit.
From Sketch to Sealed Submittal in Four Steps
Share Your Project
Send the project address, architectural plans or sketches, any survey or geotechnical report, and the permit comments your jurisdiction issued. A dimensioned sketch is enough to start.
Fixed-Fee Quote
We confirm the sheet list, the governing code edition and the schedule, then return a written fixed fee — usually the same business day, at no cost.
Design & Independent Review
Our engineers run the analysis and calculations, then a PE licensed in your state independently reviews the package before anything is sealed.
Sealed Delivery
You receive sealed, signed PDFs ready to upload to the permit portal, plus support through any plan-review comments that follow.
How We Protect You Before You Spend a Dollar
Engineering is bought on trust long before it is bought on price. These are the commitments every Residential PE engagement carries, in writing, from the first message.
Free Quote, One Fixed Fee
Consultations and quotes cost nothing. You receive one written fixed fee against a written sheet list — no hourly billing, no surprise add-ons.
A Named Engineer of Record
Every drawing is sealed by a professional engineer holding an active licence in your project’s state, and we confirm who that engineer is before you commit.
Revisions Until Approval
If the plan reviewer returns comments, we revise the sealed drawings and respond as part of the original fee — never as a change order.
Your Documents Stay Private
Drawings, surveys and site information are used only to engineer your project. They are never resold, published or used as portfolio material without consent.
48–72 Hour Turnaround
Most standard packages are sealed and returned within two to three business days, so engineering is never the reason a permit slips.
A Real Engineer Answers
Questions reach an engineer, not a call centre. Open the live chat and you are talking to someone who can actually scope and price the job.
Structural Engineering You Can Submit With Confidence
Licensed U.S. Structural Engineers
Your drawings are produced and sealed by professional engineers holding active licensure in the state of record — never by unlicensed drafters working under a borrowed seal.
Jurisdiction-Specific Compliance
We design to the code edition and local amendments your reviewer actually enforces, which differ far more between jurisdictions than most out-of-state firms account for.
Calculations You Can Defend
Every package ships with the supporting calculations, so when a reviewer questions a member size or a load path there is a sealed answer already in the file.
48–72 Hour Turnaround
Standard residential and light commercial structural packages are returned within two to three business days without compromising the review step.
Built to Pass the First Review
Across 2,200+ delivered projects our sets are built to survive plan review the first time — the only metric that actually shortens a construction schedule.
Support Until the Permit Issues
If comments come back, we revise and respond as part of the engagement. The engineer of record stays on your project until the permit is in hand.

Structural Engineering Questions We Are Asked Most
What is included in a structural engineering package?
A typical package includes the foundation plan, floor and roof framing plans, the lateral system, structural sections and details, general structural notes, and the full load calculation package — all sealed by the engineer of record. The exact sheet list is confirmed in writing before work begins.
Are your structural engineers licensed in my state?
Yes. A professional engineer seal is only valid in the state where the engineer holds an active licence, so every project is assigned to a PE licensed in that jurisdiction. Note that Illinois is a special case — structural design there requires an Illinois Structural Engineer (SE) licence, and we assign an SE accordingly.
How fast can I get sealed structural drawings?
Most standard residential and light commercial packages are delivered within 48 to 72 hours of receiving complete information. Larger or more complex structures are quoted with a specific schedule up front rather than an optimistic estimate.
Do you provide the load calculations, or only the drawings?
Calculations are included as standard. Gravity, wind, seismic and snow loads are derived per ASCE 7 and the adopted code edition, and the sealed calculation package is delivered alongside the drawings because most reviewers ask for it.
Can you review and seal drawings someone else prepared?
Yes — that is our Review and Stamp service. An engineer licensed in your state reviews the existing set against local code, requests any corrections needed to make it compliant, and then applies the seal.
Do I need a geotechnical report before you can design my foundation?
Not always. Where a soils report exists we design to its recommended bearing capacity and any special requirements. Where one does not, we can design to the code presumptive bearing values if the jurisdiction accepts that approach — we will tell you which applies before starting.
Can you write a letter for removing a load-bearing wall?
Yes. We assess the existing framing, size the replacement beam and its supports down to the foundation, and issue sealed drawings or an engineer’s letter in whatever format your building department or HOA requires.
What happens if the plan reviewer returns comments?
We respond to comments and revise the sealed drawings as part of the original engagement, not as a separate change order. Responding to a reviewer is a normal part of permitting and it is built into the fee.
One Engineering Team for the Whole Submittal
Most permit packages need more than one discipline. Keeping them with one firm removes the coordination gaps between sheets that cause the majority of plan-review rejections.
