Our Full Scope
Structural · Civil · Forensic · Permits
Most engineering firms specialize in one area. We deliver the complete spectrum — all PE-licensed, all under one roof. You shouldn't need three different firms for one project.
Structural & Foundation Inspections
On-site PE inspections for residential and commercial properties — pre-purchase, damage assessments, insurance, and permits.
Forensic Investigations
Root-cause engineering analysis for structural failures, construction defects, and insurance or litigation reports.
Structural Plans & Calculations
PE-stamped structural drawings and engineering calculations for all project types across 26 states.
Permit-Ready Documents
Turnkey construction document packages formatted for local building departments — minimizing review cycles.
Permit Expediting
We manage the permitting process end-to-end — submissions, plan review responses, resubmittals, and approvals.
Construction Administration
Engineering support during construction — RFIs, shop drawing review, site observations, and structural clarifications.
Civil Engineering
Site plans, grading, drainage, stormwater, utilities, and civil construction documents for development projects.
Nationwide Coverage
7,500+ projects across 26 states — we know your local codes, wind zones, and building departments.
Regional Expertise
We Know Local Engineering
Every region presents unique engineering challenges — hurricane zones, seismic areas, snow loads, expansive soils, and varying state building codes. With 7,500+ projects completed, our engineers understand regional requirements deeply.
Our Commitment
What Sets Us Apart
PE-Licensed & Code Compliant
Every plan, calculation, letter, and report is reviewed and sealed by a licensed Professional Engineer authorized in the project jurisdiction.
Nationwide Local Knowledge
7,500+ projects completed — we know local codes, wind zones, flood plains, and building departments.
No Project Too Small
A homeowner needing a simple deck letter gets the same professionalism as a $10M commercial client. We serve all sizes.
Our Partner Network
State-Licensed Engineering Partners
Licensed Structural Engineers (LSE) partners with state-specific licensed engineering entities to provide local, PE-stamped structural engineering services in every jurisdiction we serve. Each partner firm holds active Professional Engineer licensure in its respective state and operates under a state-branded identity to ensure clear jurisdictional accountability. All engineering work is performed or directly supervised by PE-licensed professionals in the project's state.
This partnership structure ensures that every project — from a homeowner permit letter to a full commercial engineering package — is stamped by a Professional Engineer licensed in that specific state. Clients benefit from localized expertise (building codes, climate conditions, building department relationships) delivered through a nationally coordinated network. All partner entities carry appropriate professional liability insurance and maintain active state board registration.
