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.

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.

Compliance Note: Licensed Structural Engineers (LSE) operates through a network of state-licensed partner engineering entities including those listed above. Each partner is a legally separate Professional Engineering firm registered in its respective state. Engineering services are provided by the partner entity licensed in the project's jurisdiction. This structure ensures full compliance with state engineering practice acts, board regulations, and professional liability requirements in every state we serve. For verification of any entity's licensure status, please contact the relevant state board of professional engineers.
